+/** \page Page_BuildSystem The LUFA Build System

+ *

+ *  \section Sec_BuildSystem_Overview Overview of the LUFA Build System

+ *  The LUFA build system was originally an attempt at making a set of

+ *  re-usable, modular build make files which could be referenced in a LUFA

+ *  powered project, to minimize the amount of code required in an

+ *  application makefile.

+ *

+ *  As it turned out to be fairly generic in nature, it was split out into its

+ *  own separate project, called DMBS (<i>Dean's Makefile Build System</i>)

+ *  which is released into the public domain. LUFA-specific portions of the

+ *  LUFA build system extend DMBS, and provide a universal build system for all

+ *  LUFA projects.

+ *

+ *  The latest DMBS project information and documentation can be found at:

+ *  https://github.com/abcminiuser/dmbs

+ *

+ *  DMBS is written in GNU Make, and each module is independent of one-another.

+ *

+ *  LUFA now uses DMBS for its build system, with some LUFA specific extension

+ *  modules.

+ *

+ *  If you have problems building using LUFA, see \subpage Page_BuildTroubleshooting for resolution steps.

+ *

+ *  \li \subpage Page_BuildModule_LUFA_SOURCES - The LUFA SOURCES extension module for DMBS

+ *  \li \subpage Page_BuildModule_LUFA_GCC - The LUFA GCC extension module for DMBS

+/** \page Page_BuildModule_LUFA_SOURCES LUFA SOURCES extension module for DMBS

+ *

+ *  The LUFA SOURCES extension more for DMBS provides LUFA specific variables

+ *  listing the various LUFA source files required to be build by a project for

+ *  a given LUFA module. This module gives a way to reference LUFA source files

+ *  symbolically, so that changes to the library structure do not break the

+ *  library makefile.

+ *  used in a build environment. Missing utilities and incorrectly set makefile

+ *  configuration options can also result in different errors being produced

+ *  when compilation or other operations are attempted. The table below lists a

+/** \page Page_BuildLibrary Building as a Linkable Library
+ *
+ *  The LUFA library can be built as a proper linkable library (with the extension .a) under AVR-GCC, so that
+ *  the library does not need to be recompiled with each revision of a user project. Instructions for creating
+ *  a library from a given source tree can be found in the AVR-GCC user manual included in the WinAVR install
+ *  /Docs/ directory.
+ *
+ *  However, building the library is <b>not recommended</b>, as the static (compile-time) options will be
+ *  unable to be changed without a recompilation of the LUFA code. Therefore, if the library is to be built
+ *  from the LUFA source, it should be made to be application-specific and compiled with the static options
+ *  that are required for each project (which should be recorded along with the library).
+ *
+ *  Normal library use has the library components compiled in at the same point as the application code, as
+ *  demonstrated in the library demos and applications. This is the preferred method, as the library is recompiled
+ *  each time to ensure that all static options for a particular application are applied.

+  *    and USB_Host_IsBusSuspended()
+  *  - Renamed *_*_Is* macros to *_Is* to make all flag checking macros consistent, Pipe_SetInterruptFreq() is now
+  *    Pipe_SetInterruptPeriod() to use the correct terminology
+  *  - UnicodeString member of USB_Descriptor_String_t struct changed to an ordinary int array type, so that the GCC
+  *    Unicode strings (prefixed with an L before the opening quotation mark) can be used instead of explicit arrays
+  *    of ASCII characters
+  *  - Fixed Endpoint/Pipes being configured incorrectly if the maximum endpoint/pipe size for the selected USB AVR

+  *    the real high speed mode, which is unavailable on the USB AVRs)
+  *
+  *
+  *  \section Sec_ChangeLog120 Version 1.2.0 (080204)
+  *

+  *  - Mass Storage Host demo application updated to function correctly with all USB flash disks

+  *  - Fixed incorrect device reset routine being called in USBTask
+  *  - Devices which do not connect within the standard 300mS are now supported

+/** \page Page_TokenSummary Summary of Compile Tokens
+ *
+ *  The following lists all the possible tokens which can be defined in a project makefile, and passed to the
+ *  compiler via the -D switch, to alter the LUFA library code. These tokens may alter the library behaviour,
+ *  or remove features unused by a given application in order to save flash space.
+ *
+ *  \note If the \c USE_LUFA_CONFIG_HEADER token is defined, the library will include a header file named \c LUFAConfig.h located
+ *        in the user directory where the below compile time tokens may be defined. This allows for an alternative to makefile
+ *        defined tokens for configuring the library.
+ *
+ *  \section Sec_TokenSummary_NonUSBTokens Non USB Related Tokens
+ *  This section describes compile tokens which affect non-USB sections of the LUFA library.
+ *
+ *  \li <b>DISABLE_TERMINAL_CODES</b> - (\ref Group_Terminal) - <i>All Architectures</i> \n
+ *      If an application contains ANSI terminal control codes listed in TerminalCodes.h, it might be desired to remove them
+ *      at compile time for use with a terminal which is non-ANSI control code aware, without modifying the source code. If
+ *      this token is defined, all ANSI control codes in the application code from the TerminalCodes.h header are removed from
+ *      the source code at compile time.
+ *
+ *
+ *  \section Sec_TokenSummary_USBClassTokens USB Class Driver Related Tokens
+ *  This section describes compile tokens which affect USB class-specific drivers in the LUFA library.
+ *
+ *  \li <b>HID_HOST_BOOT_PROTOCOL_ONLY</b> - (\ref Group_USBClassHIDHost) - <i>All Architectures</i> \n
+ *      By default, the USB HID Host class driver is designed to work with HID devices using either the Boot or Report HID
+ *      communication protocols. On devices where the Report protocol is not used (i.e. in applications where only basic
+ *      Mouse or Keyboard operation is desired, using boot compatible devices), the code responsible for the Report protocol
+ *      mode can be removed to save space in the compiled application by defining this token. When defined, it is still necessary
+ *      to explicitly put the attached device into Boot protocol mode via a call to \ref HID_Host_SetBootProtocol().
+ *
+ *  \li <b>HID_STATETABLE_STACK_DEPTH</b>=<i>x</i> - (\ref Group_HIDParser) - <i>All Architectures</i> \n
+ *      HID reports may contain PUSH and POP elements, to store and retrieve the current HID state table onto a stack. This
+ *      allows for reports to save the state table before modifying it slightly for a data item, and then restore the previous
+ *      state table in a compact manner. This token may be defined to a non-zero 8-bit value to give the maximum depth of the state
+ *      table stack. If not defined, this defaults to the value indicated in the HID.h file documentation.
+ *
+ *  \li <b>HID_USAGE_STACK_DEPTH</b>=<i>x</i> - (\ref Group_HIDParser) - <i>All Architectures</i> \n
+ *      HID reports generally contain many USAGE elements, which are assigned to INPUT, OUTPUT and FEATURE items in succession
+ *      when multiple items are defined at once (via REPORT COUNT elements). This allows for several items to be defined with
+ *      different usages in a compact manner. This token may be defined to a non-zero 8-bit value to set the maximum depth of the
+ *      usage stack, indicating the maximum number of USAGE items which can be stored temporarily until the next INPUT, OUTPUT
+ *      and FEATURE item. If not defined, this defaults to the value indicated in the HID.h file documentation.
+ *
+ *  \li <b>HID_MAX_COLLECTIONS</b>=<i>x</i> - (\ref Group_HIDParser) - <i>All Architectures</i> \n
+ *      HID reports generally contain several COLLECTION elements, used to group related data items together. Collection information
+ *      is stored separately in the processed usage structure (and referred to by the data elements in the structure) to save space.
+ *      This token may be defined to a non-zero 8-bit value to set the maximum number of COLLECTION items which can be processed by the
+ *      parser into the resultant processed report structure. If not defined, this defaults to the value indicated in the HID.h file
+ *      documentation.
+ *
+ *  \li <b>HID_MAX_REPORTITEMS</b>=<i>x</i> - (\ref Group_HIDParser) - <i>All Architectures</i> \n
+ *      All HID reports contain one or more INPUT, OUTPUT and/or FEATURE items describing the data which can be sent to and from the HID
+ *      device. Each item has associated usages, bit offsets in the item reports and other associated data indicating the manner in which
+ *      the report data should be interpreted by the host. This token may be defined to a non-zero 8-bit value to set the maximum number of
+ *      data elements which can be stored in the processed HID report structure, including INPUT, OUTPUT and (if enabled) FEATURE items.
+ *      If a item has a multiple count (i.e. a REPORT COUNT of more than 1), each item in the report count is placed separately in the
+ *      processed HID report table. If not defined, this defaults to the value indicated in the HID.h file documentation.
+ *
+ *  \li <b>HID_MAX_REPORT_IDS</b>=<i>x</i> - (\ref Group_HIDParser) - <i>All Architectures</i> \n
+ *      HID reports may contain several report IDs, to logically distinguish grouped device data from one another - for example, a combination
+ *      keyboard and mouse might use report IDs to separate the keyboard reports from the mouse reports. In order to determine the size of each
+ *      report, and thus know how many bytes must be read or written, the size of each report (IN, OUT and FEATURE) must be calculated and
+ *      stored. This token may be defined to a non-zero 8-bit value to set the maximum number of report IDs in a device which can be processed
+ *      and their sizes calculated/stored into the resultant processed report structure. If not defined, this defaults to the value indicated in
+ *      the HID.h file documentation.
+ *
+ *  \li <b>NO_CLASS_DRIVER_AUTOFLUSH</b> - (\ref Group_USBClassDrivers) - <i>All Architectures</i> \n
+ *      Many of the device and host mode class drivers automatically flush any data waiting to be written to an interface, when the corresponding
+ *      USB management task is executed. This is usually desirable to ensure that any queued data is sent as soon as possible once and new data is
+ *      constructed in the main program loop. However, if flushing is to be controlled manually by the user application via the *_Flush() commands,
+ *      the compile time token may be defined in the application's makefile to disable automatic flushing during calls to the class driver USB
+ *      management tasks.
+ *
+ *
+ *  \section Sec_TokenSummary_USBTokens General USB Driver Related Tokens
+ *  This section describes compile tokens which affect USB driver stack as a whole in the LUFA library.
+ *
+ *  \li <b>ORDERED_EP_CONFIG</b> - (\ref Group_EndpointManagement , \ref Group_PipeManagement) - <i>AVR8, UC3</i> \n
+ *      The USB AVRs do not allow for Endpoints and Pipes to be configured out of order; they <i>must</i> be configured in an ascending order to
+ *      prevent data corruption issues. However, by default LUFA employs a workaround to allow for unordered Endpoint/Pipe initialization. This compile
+ *      time token may be used to restrict the initialization order to ascending indexes only in exchange for a smaller compiled binary size. Use
+ *      caution when applied to applications using the library USB Class drivers; the user application must ensure that all endpoints and pipes are
+ *      allocated sequentially.
+ *
+ *  \li <b>USE_STATIC_OPTIONS</b>=<i>x</i> - (\ref Group_USBManagement) - <i>All Architectures</i> \n
+ *      By default, the USB_Init() function accepts dynamic options at runtime to alter the library behaviour, including whether the USB pad
+ *      voltage regulator is enabled, and the device speed when in device mode. By defining this token to a mask comprised of the USB options
+ *      mask defines usually passed as the Options parameter to USB_Init(), the resulting compiled binary can be decreased in size by removing
+ *      the dynamic options code, and replacing it with the statically set options. When defined, the USB_Init() function no longer accepts an
+ *      Options parameter.
+ *
+ *  \li <b>USB_DEVICE_ONLY</b> - (\ref Group_USBManagement) - <i>All Architectures</i> \n
+ *      For the USB AVR models supporting both device and host USB modes, the USB_Init() function contains a Mode parameter which specifies the
+ *      mode the library should be initialized to. If only device mode is required, the code for USB host mode can be removed from the binary to
+ *      save space. When defined, the USB_Init() function no longer accepts a Mode parameter. This define is irrelevant on smaller USB AVRs which
+ *      do not support host mode.
+ *
+ *  \li <b>USB_HOST_ONLY</b> - (\ref Group_USBManagement) - <i>All Architectures</i> \n
+ *      Same as USB_DEVICE_ONLY, except the library is fixed to USB host mode rather than USB device mode. Not available on some USB AVR models.
+ *
+ *  \li <b>USB_STREAM_TIMEOUT_MS</b>=<i>x</i> - (\ref Group_USBManagement) - <i>All Architectures</i> \n
+ *      When endpoint and/or pipe stream functions are used, by default there is a timeout between each transfer which the connected device or host
+ *      must satisfy, or the stream function aborts the remaining data transfer. This token may be defined to a non-zero 16-bit value to set the timeout
+ *      period for stream transfers, specified in milliseconds. If not defined, the default value specified in LowLevel.h is used instead.
+ *
+ *  \li <b>NO_LIMITED_CONTROLLER_CONNECT</b> - (\ref Group_Events) - <i>AVR8 Only</i> \n
+ *      On the smaller USB AVRs, the USB controller lacks VBUS events to determine the physical connection state of the USB bus to a host. In lieu of
+ *      VBUS events, the library attempts to determine the connection state via the bus suspension and wake up events instead. This however may be
+ *      slightly inaccurate due to the possibility of the host suspending the bus while the device is still connected. If accurate connection status is
+ *      required, the VBUS line of the USB connector should be routed to an AVR pin to detect its level, so that the \ref USB_DeviceState global
+ *      can be accurately set and the \ref EVENT_USB_Device_Connect() and \ref EVENT_USB_Device_Disconnect() events manually raised by the user application.
+ *      When defined, this token disables the library's auto-detection of the connection state by the aforementioned suspension and wake up events.
+ *
+ *  \li <b>NO_SOF_EVENTS</b> - (\ref Group_Events) - <i>All Architectures</i> \n
+ *      By default, there exists a LUFA application event for the start of each USB frame while the USB bus is not suspended in either host or device mode.
+ *      This event can be selectively enabled or disabled by calling the appropriate device or host mode function. When this compile time token is defined,
+ *      the ability to receive USB Start of Frame events via the \ref EVENT_USB_Device_StartOfFrame() or \ref EVENT_USB_Host_StartOfFrame() events is removed,
+ *      reducing the compiled program's binary size.
+ *
+ *
+ *  \section Sec_TokenSummary_USBDeviceTokens USB Device Mode Driver Related Tokens
+ *  This section describes compile tokens which affect USB driver stack of the LUFA library when used in Device mode.
+ *
+ *  \li <b>USE_RAM_DESCRIPTORS</b> - (\ref Group_StdDescriptors) - <i>AVR8 Only</i> \n
+ *      Define this token to indicate to the USB driver that all device descriptors are stored in RAM, rather than being located in any one
+ *      of the AVR's memory spaces. RAM descriptors may be desirable in applications where the descriptors need to be modified at runtime.
+ *
+ *  \li <b>USE_FLASH_DESCRIPTORS</b> - (\ref Group_StdDescriptors) - <i>AVR8 Only</i> \n
+ *      Similar to USE_RAM_DESCRIPTORS, but all descriptors are stored in the AVR's FLASH memory rather than RAM.
+ *
+ *  \li <b>USE_EEPROM_DESCRIPTORS</b> - (\ref Group_StdDescriptors) - <i>AVR8 Only</i> \n
+ *      Similar to USE_RAM_DESCRIPTORS, but all descriptors are stored in the AVR's EEPROM memory rather than RAM.
+ *
+ *  \li <b>NO_INTERNAL_SERIAL</b> - (\ref Group_StdDescriptors) - <i>All Architectures</i> \n
+ *      Some AVR models contain a unique serial number which can be used as the device serial number, while in device mode. This allows
+ *      the host to uniquely identify the device regardless of if it is moved between USB ports on the same computer, allowing allocated
+ *      resources (such as drivers, COM Port number allocations) to be preserved. This is not needed in many apps, and so the code that
+ *      performs this task can be disabled by defining this option and passing it to the compiler via the -D switch.
+ *
+ *  \li <b>FIXED_CONTROL_ENDPOINT_SIZE</b>=<i>x</i> - (\ref Group_EndpointManagement) - <i>All Architectures</i> \n
+ *      By default, the library determines the size of the control endpoint (when in device mode) by reading the device descriptor.
+ *      Normally this reduces the amount of configuration required for the library, allows the value to change dynamically (if
+ *      descriptors are stored in EEPROM or RAM rather than flash memory) and reduces code maintenance. However, this token can be
+ *      defined to a non-zero value instead to give the size in bytes of the control endpoint, to reduce the size of the compiled
+ *      binary.
+ *
+ *  \li <b>DEVICE_STATE_AS_GPIOR</b> - (\ref Group_Device) - <i>AVR8 Only</i> \n
+ *      One of the most frequently used global variables in the stack is the USB_DeviceState global, which indicates the current state of
+ *      the Device State Machine. To reduce the amount of code and time required to access and modify this global in an application, this token
+ *      may be defined to a value between 0 and 2 to fix the state variable into one of the three general purpose IO registers inside the AVR
+ *      reserved for application use. When defined, the corresponding GPIOR register should not be used within the user application except
+ *      implicitly via the library APIs.
+ *
+ *  \li <b>FIXED_NUM_CONFIGURATIONS</b>=<i>x</i> - (\ref Group_Device) - <i>All Architectures</i> \n
+ *      By default, the library determines the number of configurations a USB device supports by reading the device descriptor. This reduces
+ *      the amount of configuration required to set up the library, and allows the value to change dynamically (if descriptors are stored in
+ *      EEPROM or RAM rather than flash memory) and reduces code maintenance. However, this value may be fixed via this token in the project
+ *      makefile to reduce the compiled size of the binary at the expense of flexibility.
+ *
+ *  \li <b>CONTROL_ONLY_DEVICE</b> - (\ref Group_Device) - <i>All Architectures</i> \n
+ *      In some limited USB device applications, there are no device endpoints other than the control endpoint; i.e. all device communication
+ *      is through control endpoint requests. Defining this token will remove several features related to the selection and control of device
+ *      endpoints internally, saving space. Generally, this is usually only useful in (some) bootloaders and is best avoided.
+ *
+ *  \li <b>MAX_ENDPOINT_INDEX</b> - (\ref Group_Device) - <i>XMEGA Only</i> \n
+ *      Defining this value to the highest index (not address - this excludes the direction flag) endpoint within the device will restrict the
+ *      number of FIFOs created internally for the endpoint buffers, reducing the total RAM usage.
+ *
+ *  \li <b>INTERRUPT_CONTROL_ENDPOINT</b> - (\ref Group_USBManagement) - <i>All Architectures</i> \n
+ *      Some applications prefer to not call the USB_USBTask() management task regularly while in device mode, as it can complicate code significantly.
+ *      Instead, when device mode is used this token can be passed to the library via the -D switch to allow the library to manage the USB control
+ *      endpoint entirely via USB controller interrupts asynchronously to the user application. When defined, USB_USBTask() does not need to be called
+ *      when in USB device mode.
+ *
+ *  \li <b>NO_DEVICE_REMOTE_WAKEUP</b> - (\ref Group_Device) - <i>All Architectures</i> \n
+ *      Many devices do not require the use of the Remote Wakeup features of USB, used to wake up the USB host when suspended. On these devices,
+ *      the code required to manage device Remote Wakeup can be disabled by defining this token and passing it to the library via the -D switch.
+ *
+ *  \li <b>NO_DEVICE_SELF_POWER</b> - (\ref Group_Device) - <i>All Architectures</i> \n
+ *      USB devices may be bus powered, self powered, or a combination of both. When a device can be both bus powered and self powered, the host may
+ *      query the device to determine the current power source, via \ref USB_Device_CurrentlySelfPowered. For solely bus powered devices, this global
+ *      and the code required to manage it may be disabled by passing this token to the library via the -D switch.
+ *
+ *
+ *  \section Sec_TokenSummary_USBHostTokens USB Host Mode Driver Related Tokens
+ *
+ *  This section describes compile tokens which affect USB driver stack of the LUFA library when used in Host mode.
+ *
+ *  \li <b>HOST_STATE_AS_GPIOR</b> - (\ref Group_Host) - <i>AVR8 Only</i> \n
+ *      One of the most frequently used global variables in the stack is the USB_HostState global, which indicates the current state of
+ *      the Host State Machine. To reduce the amount of code and time required to access and modify this global in an application, this token
+ *      may be defined to a value between 0 and 2 to fix the state variable into one of the three general purpose IO registers inside the AVR
+ *      reserved for application use. When defined, the corresponding GPIOR register should not be used within the user application except
+ *      implicitly via the library APIs.
+ *
+ *  \li <b>USB_HOST_TIMEOUT_MS</b>=<i>x</i> - (\ref Group_Host) - <i>All Architectures</i> \n
+ *      When a control transfer is initiated in host mode to an attached device, a timeout is used to abort the transfer if the attached
+ *      device fails to respond within the timeout period. This token may be defined to a non-zero 16-bit value to set the timeout period for
+ *      control transfers, specified in milliseconds. If not defined, the default value specified in Host.h is used instead.
+ *
+ *  \li <b>HOST_DEVICE_SETTLE_DELAY_MS</b>=<i>x</i> - (\ref Group_Host) - <i>All Architectures</i> \n
+ *      Some devices require a delay of up to 5 seconds after they are connected to VBUS before the enumeration process can be started, or
+ *      they will fail to enumerate correctly. By placing a delay before the enumeration process, it can be ensured that the bus has settled
+ *      back to a known idle state before communications occur with the device. This token may be defined to a 16-bit value to set the device
+ *      settle period, specified in milliseconds. If not defined, the default value specified in Host.h is used instead.
+ *
+ *  \li <b>INVERTED_VBUS_ENABLE_LINE</b> - (\ref Group_Host) - <i>All Architectures</i> \n
+ *      If enabled, this will indicate that the USB target VBUS line polarity is inverted; i.e. it should be pulled low to enable VBUS to the
+ *      target, and pulled high to stop the target VBUS generation.
+ *      \n
+ *      \attention On AVR8 architecture devices, this compile time option requires \c NO_AUTO_VBUS_MANAGEMENT to be set.
+ *
+ *  \li <b>NO_AUTO_VBUS_MANAGEMENT</b> - (\ref Group_Host) - <i>All Architectures</i> \n
+ *      Disables the automatic management of VBUS to the target, i.e. automatic shut down in the even of an overcurrent situation. When enabled, VBUS
+ *      is enabled while the USB controller is initialized in USB Host mode.

+/** \page Page_CompilingApps Compiling the Demos, Bootloaders and Projects
+ *
+ *  The following details how to compile the included LUFA demos, applications and bootloaders using AVR-GCC.
+ *
+ *  \section Sec_CompilingApps_Prerequisites Prerequisites
+ *  Before you can compile any of the LUFA library code or demos, you will need a recent distribution of avr-libc (1.6.2+)
+ *  and the AVR-GCC (4.2+) compiler. A standard "coreutils" package for your system is also required for command line
+ *  compilation of LUFA based applications.
+ *
+ *  \subsection SSec_CompilingApps_PreqWindows Windows Prerequisites
+ *  On Windows, you will need a copy of the latest Atmel Toolchain (<a>http://www.atmel.com/tools/ATMELAVRTOOLCHAINFORWINDOWS.aspx</a>),
+ *  either downloaded and installed as a standalone package, or installed as part of Atmel Studio. You will need to ensure
+ *  that the "bin" directory of the toolchain is available in your system's <b>PATH</b> environment variable.
+ *
+ *  In addition, you will need to install a ported version of the ZSH or BASH *nix shells, and a standard set of *nix
+ *  utilities such as <i>cut</i>, <i>find</i> and <i>sed</i>. These can be found in the "basic" system package of the
+ *  of the MinGW installer (<a>http://www.mingw.org</a>). Once installed, add the "msys\1.0\bin" of the MinGW installation
+ *  folder is added to your system's <b>PATH</b> environment variable.
+ *
+ *  \subsection SSec_CompilingApps_PreqLinux Linux Prerequisites
+ *  On Linux systems you will need to install the latest Linux distribution of the standalone Atmel Toolchain from the
+ *  Atmel website (<a>http://www.atmel.com/tools/ATMELAVRTOOLCHAINFORLINUX.aspx</a>), or use the latest avr-libc and avr-gcc packages
+ *  for your chosen distribution's package manager. For full device support, the Atmel standalone Toolchain package is recommended.
+ *
+ *  \section Sec_CompilingApps_Compiling Compiling a LUFA Application
+ *  Compiling the LUFA demos, applications and/or bootloaders is very simple. LUFA comes with makefile scripts for
+ *  each individual demo, bootloader and project folder, as well as scripts in the Demos/, Bootloaders/, Projects/
+ *  and the LUFA root directory. Compilation of projects can be started from any of the above directories, with a build
+ *  started from an upper directory in the directory structure executing build of all child directories under it. This
+ *  means that while a build inside a particular demo directory will build only that particular demo, a build started from
+ *  the /Demos/ directory will build all LUFA demo projects sequentially.
+ *
+ *  To build a project from the source via the command line, the command <b>"make all"</b> should be executed from the command
+ *  line in the directory of interest. To remove compiled files (including the binary output, all intermediately files and all
+ *  diagnostic output files), execute <b>"make clean"</b>. Once a "make all" has been run and no errors were encountered, the
+ *  resulting binary will be located in the generated ".HEX" file. If your project makes use of pre-initialized EEPROM
+ *  variables, the generated ".EEP" file will contain the project's EEPROM data.
+ *
+ *  \see \ref Page_BuildSystem for information on the LUFA build system.

+/** \page Page_ConfiguringApps Configuring the Demos, Bootloaders and Projects
+ *
+ *  If the target microcontroller model, architecture, clock speed, board or other settings are different from the current
+ *  settings, they must be changed and the project recompiled from the source code before being programmed into the microcontroller.
+ *  Most project configuration options are located in the <tt>makefile</tt> build script inside each LUFA application's folder,
+ *  however some demo or application-specific configuration settings are located in one or more of the source files of the project.
+ *  See each project's individual documentation for application-specific configuration values.
+ *
+ *  Each project "makefile" contains all the script and configuration data required to compile each project. When opened with
+ *  any regular basic text editor such as Notepad or WordPad (ensure that the save format is a pure ASCII text format) the
+ *  build configuration settings may be altered.
+ *
+ *  \see \ref Page_BuildSystem for information on the LUFA build system.
+ *
+ *  \section Sec_ConfiguringApps_AppMakefileParams The Default Application Makefile Template
+ *
+ *  Below is a copy of the default LUFA application makefile, which can be used as a template for each application.
+ *
+ *  \verbinclude makefile_template
+ *
+ *  Inside each makefile, a number of configuration variables are listed with the syntax "<VARIABLE NAME> = <VALUE>". For
+ *  each application, the important standard variables which should be altered are:
+ *
+ *    - <b>MCU</b>, the target processor model
+ *    - <b>ARCH</b>, the target microcontroller architecture
+ *    - <b>BOARD</b>, the target board hardware
+ *    - <b>F_CPU</b>, the target CPU master clock frequency, after any prescaling
+ *    - <b>F_USB</b>, the target raw input clock to the USB module of the processor
+ *    - <b>OPTIMIZATION</b>, the level of optimization to compile with
+ *    - <b>TARGET</b>, the name of the target output binary and other files
+ *    - <b>SRC</b>, the list of source files to compile/assemble/link
+ *    - <b>LUFA_PATH</b>, the path to the LUFA library core source code
+ *    - <b>CC_FLAGS</b>, the common command line flags to pass to the C/C++ compiler, assembler and linker
+ *    - <b>LD_FLAGS</b>, the command line flags to pass to the linker
+ *
+ *  These values should be changed to reflect the build hardware.
+ *
+ *  \subsection SSec_ConfiguringApps_MCU The MCU Parameter
+ *  This parameter indicates the target microcontroller model for the compiled application. This should be set to the model of the target
+ *  microcontroller (such as the AT90USB1287, or the ATMEGA32U4), in all lower-case (e.g. "at90usb1287"). Note that not all demos support all the
+ *  microcontroller models and architectures, as they may make use of peripherals or modes only present in some devices.
+ *
+ *  For supported processor models, see \ref Page_DeviceSupport.
+ *
+ *  \subsection SSec_ConfiguringApps_ARCH The ARCH Parameter
+ *  This parameter indicates the target microcontroller architecture the library is to be compiled for. Different microcontroller
+ *  architectures require different source files to be compiled into the final binary, and so this option must be set to the correct
+ *  architecture for the selected platform.
+ *
+ *  For supported processor architectures, see \ref Page_DeviceSupport.
+ *
+ *  \subsection SSec_ConfiguringApps_BOARD The BOARD Parameter
+ *  This parameter indicates the target board hardware for the compiled application. Some LUFA library drivers are board-specific,
+ *  such as the LED driver, and the library needs to know the layout of the target board. If you are using one of the board models listed
+ *  on the main library page, change this parameter to the board name in all UPPER-case.
+ *
+ *  If you are not using any board-specific drivers in the LUFA library, or you are using a custom board layout, change this to read
+ *  "USER" (no quotes) instead of a standard board name. If the USER board type is selected and the application makes use of one or more
+ *  board-specific hardware drivers inside the LUFA library, then the appropriate stub drives files should be copied from the \c /CodeTemplates/DriverStubs/
+ *  directory into a /Board/ folder inside the application directory, and the stub driver completed with the appropriate code to drive the
+ *  custom board's hardware.
+ *
+ *  For boards with built in hardware driver support within the LUFA library, see \ref Page_DeviceSupport.
+ *
+ *  \subsection SSec_ConfiguringApps_F_CPU The F_CPU Parameter
+ *  This parameter indicates the target microcontroller's main CPU clock frequency, in Hz. This is used by many libraries (and applications) for
+ *  timing related purposes, and should reflect the actual CPU speed after any prescaling or adjustments are performed.
+ *
+ *  \subsection SSec_ConfiguringApps_F_USB The F_USB Parameter
+ *  This parameter indicates the raw input clock frequency to the USB module within the microcontroller in Hz. This may be very different on some platforms
+ *  to the main CPU clock or other peripheral/bus clocks.
+ *
+ *    \note On AVR8 platforms, this must be equal to \c 8000000 or \c 16000000.
+ *
+ *    \note On XMEGA platforms, this must be equal to a multiple of 6000000 from \c 6000000 to \c 48000000.
+ *
+ *    \note On UC3 platforms, this must be equal to a multiple of 12000000 from \c 12000000 to \c 48000000.
+ *
+ *  \subsection SSec_ConfiguringApps_OPTIMIZATION The OPTIMIZATION Parameter
+ *  This parameter indicates the level of optimization to use when compiling the application. This will allow you to compile with an optimization level
+ *  supported by GCC, from <tt>0</tt> (no optimization) to <tt>3</tt> (fastest runtime optimization) or <tt>s</tt> (smallest size).
+ *
+ *  \subsection SSec_ConfiguringApps_TARGET The TARGET Parameter
+ *  This parameter indicates the application target name, which is used as the base filename for the build binary and debugging files. This will be the
+ *  name of the output files once linked together into the final application, ready to load into the target.
+ *
+ *  \subsection SSec_ConfiguringApps_SRC The SRC Parameter
+ *  This parameter indicates the source files used to compile the application, as a list of C (<tt>*.c</tt>), C++ (<tt>*.cpp</tt>) and Assembly (<tt>*.S</tt>) files. Note that
+ *  all assembly files must end in a <b>capital</b> .S extension, as lowercase .s files are reserved for GCC intermediate files.
+ *
+ *  \subsection SSec_ConfiguringApps_LUFA_PATH The LUFA_PATH Parameter
+ *  As each LUFA program requires the LUFA library source code to compile correctly, the application must know where the LUFA library is located. This
+ *  value specifies the path to the LUFA library core. This path may be relative or absolute, however note than even under Windows based systems the
+ *  forward-slash (/) path separator must be used.
+ *
+ *  \subsection SSec_ConfiguringApps_CC_FLAGS The CC_FLAGS Parameter
+ *  This parameter lists the compiler flags passed to the C/C++ compiler, the assembler and the linker. These are used as-is directly to GCC and thus
+ *  must match GCC's command line options as given in the GCC manual. This variable may be used to define tokens directly on the command line, enable or
+ *  disable warnings, adjust the target-specific tuning parameters or other options.
+ *
+ *  \subsection SSec_ConfiguringApps_LD_FLAGS The LD_FLAGS Parameter
+ *  This parameter lists the linker flags passed exclusively to the linker. These are used as-is directly to GCC and thus must match GCC's command line
+ *  linker options as given in the GCC manual. This variable may be used to create or relocate custom data sections, or enable linker specific behaviors.
+ *
+ *
+ *  \section Sec_ExampleAppConfig Example Application Makefile Configurations

+/** \page Page_GettingStarted Getting Started
+ *
+ *  Getting started with LUFA is easy; read the content below to get on your way to your first LUFA powered application.
+ *
+ *  \section Sec_DemosOverview The LUFA Demo Applications
+ *
+ *  Out of the box, LUFA contains a large number of pre-made class demos for you to test, experiment with and
+ *  ultimately build upon for your own projects. All the demos (where possible) come pre-configured to build and
+ *  run correctly on the AT90USB1287 AVR microcontroller, mounted on the Atmel USBKEY board and running at an 8MHz
+ *  master clock. This is due to two reasons; one, it is the hardware the author possesses, and two, it is the most
+ *  popular Atmel USB demonstration board to date. To learn how to reconfigure, recompile and program the included
+ *  LUFA applications using different settings, see the subsections below.
+ *
+ *  \section Sec_ClassOrLowLevel Class Driver and Low Level Demos
+ *
+ *  Most of the included demos in the /Demos/ folder come in both ClassDriver and LowLevel varieties. If you are new
+ *  to LUFA, it is highly recommended that you look at the ClassDriver versions first, which use the pre-made USB
+ *  Class Drivers (\ref Group_USBClassDrivers) to simplify the use of the standard USB classes in user applications.
+ *  These demos give a basic but easy to use interface to the USB class used in the demo application, such as HID or
+ *  CDC.
+ *
+ *  Those needing absolute control over the class implementation can look at the LowLevel demos, which implement the
+ *  required USB class directly in the demo application using the lowest level LUFA APIs.
+ *
+ *
+ *  <b>Subsections:</b>
+ *  \li \subpage Page_ConfiguringApps - How to Configure the Included Demos, Projects and Bootloaders
+ *  \li \subpage Page_CompilingApps - How to Compile the Included Demos, Projects and Bootloaders
+ *  \li \subpage Page_ProgrammingApps - How to Program an AVR with the Included Demos, Projects and Bootloaders

+  *  The following are known issues present in each official LUFA release. This list should contain all known
+  *  issues in the library. Most of these issues should be corrected in the future release - see
+  *  \ref Page_FutureChanges for a list of planned changes in future releases.
+  *
+  *  \section Sec_KnownIssues170418 Version 170418
+  *  - AVR8 Architecture
+  *    - No known issues.
+  *  - UC3 Architecture
+  *    \warning The UC3 device support is currently <b>experimental</b> (incomplete and/or non-functional), and is included for preview purposes only. \n
+  *
+  *    - No demos, bootloaders or projects have been ported for the UC3 devices in the current release,
+  *      although the architecture is supported in the LUFA core library.
+  *    - DMA transfers to and from the USB controller are not yet implemented for this release.
+  *    - The UC3C, UC3D and UC3L sub-families of UC3 are not currently supported by the library due to their
+  *      altered USB controller design.
+  *    - The various \c *_CreateStream() functions for creating standard \c <stdio.h> compatible virtual file
+  *      streams are not available on the UC3 architecture, due to a lack of suitable library support.
+  *  - XMEGA Architecture
+  *    \warning The XMEGA device support is currently <b>experimental</b> (incomplete and/or non-functional), and is included for preview purposes only.
+  *
+  *    - Endpoints of more than 64 bytes are not currently supported in this release.
+  *    - Isochronous endpoints are not currently supported in this release. As a result, the audio class
+  *      cannot be used on XMEGA devices.
+  *    - Multiple-bank endpoints are not currently supported in this release.
+  *    - Early silicon revisions of the ATXMEGA128A1U are incompatible with LUFA, due to their various errata
+  *      relating to the USB controller.
+  *  - Architecture Independent
+  *    - The LUFA library is not watchdog aware, and thus timeouts are possible if short periods are used
+  *      and a lengthy USB operation is initiated.
+  *    - No LUFA provided driver INF files for Windows are signed, and thus may fail to install on systems where driver signing is enforced (e.g. Windows 8/10).
+  *  - Build System
+  *    - No known issues.
+  *  - Atmel Studio Integration
+  *    - Not all devices are listed in the "Supported Parts" screen when selecting a device. To select an alternative device, change the "Show Device" drop-down to "All Parts".
+  *    - When switching boards after changing the device selection, a second conflicting \c BOARD symbol definition can be created that prevents successful compilation. To fix, open the project properties window (<i>Project->Project {name} Properties...</i> menu item), click the "Toolchain" tab, click "Symbols" under the "AVR/GNU C Compiler" section and remove the incorrect definition.

+ *  <b>LUFA is donationware. For author and donation information, see \ref Page_Donating.</b>
+ *
+ *  LUFA is an open-source USB library for the USB-enabled AVR microcontrollers, released under the MIT license (see \ref Page_LicenseInfo).
+ *  It supports a large number of USB AVR models and boards (see \ref Page_DeviceSupport). It is designed to provide an easy to use,
+ *  feature rich framework for the development of USB peripherals and hosts.
+ *
+ *  LUFA focuses on the microcontroller side of USB development only; it includes no PC host USB driver development facilities - other projects
+ *  such as the Windows Driver Development Kit, Windows USB Device Mode Framework and libusb may be of interest for developing custom OS drivers.
+ *  While custom USB devices can be made with LUFA using such tools, the included demos all use the inbuilt OS drivers for each USB class for
+ *  simplicity.
+ *
+ *  The library is currently in a stable release, suitable for download and incorporation into user projects for
+ *  both host and device modes. For information about the project progression, see the blog link at \ref Page_Resources.
+ *
+ *  LUFA is written specifically for the free AVR-GCC compiler, and uses several GCC-only extensions to make the
+ *  library API more streamlined and robust. You can download AVR-GCC for free in a convenient windows package,
+ *  from the the WinAVR website (see \ref Page_Resources).
+ *
+ *  The only required AVR peripherals for LUFA is the USB controller itself and interrupts - LUFA does not require the use of the
+ *  microcontroller's timers or other hardware, leaving more hardware to the application developer.
+ *
+ *  Accompanying LUFA in the download package is a set of example demo applications, plus several Bootloaders of different classes
+ *  and open source LUFA powered projects.

+/** \page Page_Migration Migrating from Older Versions
+ *
+ *  Below is migration information for updating existing projects based on previous versions of the LUFA library
+ *  to the next version released. It does not indicate all new additions to the library in each version change, only
+ *  areas relevant to making older projects compatible with the API changes of each new release.
+ *
+ *  \section Sec_Migration170418 Version 170418
+ *  <b>Device Mode</b>
+ *   - The \c CALLBACK_USB_GetDescriptor() callback function into the user application's \c wIndex parameter is now \c uint16_t, not \c uint8_t.
+ *
+ *  \section Sec_Migration151115 Migrating from 140928 to 151115
+ *  <b>Non-USB Library Components</b>
+ *    - The ATPROGRAM LUFA build system module now defaults to the Atmel ICE debugger tool, instead of the Atmel JTAG ICE3.
+ *    - The \c Serial_CreateStream() and \c Serial_CreateBlockingStream() functions now require a USART base pointer for XMEGA devices as the first parameter.
+ *
+ *  \section Sec_Migration140928 Migrating from 140302 to 140928
+ *  <b>Device Mode</b>
+ *    - The device mode RNDIS class driver now requires a user-supplied buffer and buffer length to operate, rather
+ *      than allocating this buffer internally.
+ *
+ *  \section Sec_Migration140302 Migrating from 130901 to 140302
+ *  <b>USB Core</b>
+ *    - The \c VERSION_BCD() macro has changed from accepting one floating point parameter to taking three distinct major/minor/revision integer parameters, as
+ *      some edge cases caused incorrect parsing of the input float into the final integer BCD encoded value.
+ *
+ *  <b>Non-USB Library Components</b>
+ *    - The \c ATTR_NEVER_INLINE macro, erroneously introduced in a previous release has been removed, as it duplicates the existing \c ATTR_NO_INLINE macro.
+ *
+ *  <b>Build System</b>
+ *    - The default configuration file for Doxygen is now "doxyfile" rather than "Doxygen.conf", to conform to the Doxygen project's own default file name.
+ *      Set \c DOXYGEN_CONF to override the new default file name.
+ *
+ *  \section Sec_Migration130901 Migrating from 130303 to 130901
+ *  <b>Non-USB Library Components</b>
+ *    - The Board Dataflash \c Dataflash_Init() function now automatically configures the appropriate communication interface.
+ *
+ *  \section Sec_Migration130303 Migrating from 120730 to 130303
+ *  <b>Device Mode</b>
+ *    - The \ref HID_KEYBOARD_LED_KANA macro was previously misspelled as \c HID_KEYBOARD_LED_KATANA, and had an incorrect value. User applications requiring this
+ *      constant should use the new name, and remove any workarounds for the previously incorrect macro definition.
+ *    - The \c HID_KEYBOARD_SC_EQUAL_SIGN macro has been renamed to \ref HID_KEYBOARD_SC_KEYPAD_EQUAL_SIGN, and the previous definition of
+ *      \c HID_KEYBOARD_SC_KEYPAD_EQUAL_SIGN has been renamed \ref HID_KEYBOARD_SC_KEYPAD_EQUAL_SIGN_AS400 to conform to the definitions in the HID specification.
+ *
+ *  <b>Host Mode</b>
+ *    - The \ref HID_KEYBOARD_LED_KANA macro was previously misspelled as \c HID_KEYBOARD_LED_KATANA, and had an incorrect value. User applications requiring this
+ *      constant should use the new name, and remove any workarounds for the previously incorrect macro definition.
+ *    - The \c HID_KEYBOARD_SC_EQUAL_SIGN macro has been renamed to \ref HID_KEYBOARD_SC_KEYPAD_EQUAL_SIGN, and the previous definition of
+ *      \c HID_KEYBOARD_SC_KEYPAD_EQUAL_SIGN has been renamed \ref HID_KEYBOARD_SC_KEYPAD_EQUAL_SIGN_AS400 to conform to the definitions in the HID specification.
+ *
+ *  \section Sec_Migration120730 Migrating from 120219 to 120730
+ *  <b>Device Mode</b>
+ *    - The device mode Audio Class driver now requires an additional configuration parameter, the Audio Control interface index. Existing applications should
+ *      be adjusted to specify the additional configuration parameter.
+ *    - The HID_DESCRIPTOR_JOYSTICK() macro no longer takes a variable number of axis as a parameter, due to OS incompatibilities; this macro now uses a fixed
+ *      3 axis of data. User applications should update their calls to this macro and their report structures to suit a fixed 3-axis joystick report. If a user
+ *      application requires more than 3 axis' of data, a custom report descriptor will need to be constructed by hand.
+ *    - The \ref Endpoint_ConfigureEndpoint() function no longer takes in masks for the banks and direction; the number of banks is now an integer argument, and
+ *      the direction is obtained from the full endpoint address within the device. Applications calling Endpoint_ConfigureEndpoint() should update their API
+ *      call to use a full endpoint address (including ENDPOINT_DIR_IN or ENDPOINT_DIR_OUT direction in the MSB of the endpoint address) and an integer number
+ *      of banks.
+ *    - All endpoint functions now operate on full endpoint addresses within the device, rather than a directionless endpoint index. Applications should update
+ *      their API calls to use full endpoint addresses when required within the device.
+ *    - All device mode class drivers have been updated to use a new unified endpoint description structure for all endpoints; existing applications will need
+ *      to update their class driver struct instantiation to match the new scheme (see \ref USB_Endpoint_Table_t).
+ *    - The \c ENDPOINT_BANKS_SUPPORTED() and \c ENDPOINT_MAX_ENDPOINT_SIZE() macros have been removed, as these do not function correctly with the new addressing
+ *      scheme for the endpoint APIs. Please refer to the target device's datasheet for the maximum bank size of each endpoint.
+ *    - The MIDI class driver \ref MIDI_EventPacket_t event packet no longer contains separate \c CableIndex and \c Command entries; these have been combined
+ *      into a single \c Event element which can be constructed using the new macro \ref MIDI_EVENT(). Existing applications should use the new macro and structure
+ *      element name.
+ *
+ *  <b>Host Mode</b>
+ *    - The Android Accessory Host class driver property strings are now a array of \c char* rather than a struct of named pointers. Existing applications
+ *      should use C99 Designated Initializers with the property string indexes located in \ref AOA_Strings_t instead.
+ *    - The \ref Pipe_ConfigurePipe() function no longer takes in masks for the banks and token; the number of banks is now an integer argument, and the token
+ *      is now inferred from the full pipe address within the device, and the pipe type. Applications calling Pipe_ConfigurePipe() should update their API
+ *      call to use a full pipe address (including PIPE_DIR_IN or PIPE_DIR_OUT direction in the MSB of the pipe address) and an integer number of banks.
+ *    - All pipe functions now operate on full pipe addresses within the device, rather than a directionless pipe index. Applications should update their API
+ *      calls to use full pipe addresses when required within the device.
+ *    - All host mode class drivers have been updated to use a new unified pipe description structure for all pipes; existing applications will need to update
+ *      their class driver struct instantiation to match the new scheme (see \ref USB_Pipe_Table_t).
+ *    - The MIDI class driver \ref MIDI_EventPacket_t event packet no longer contains seperate \c CableIndex and \c Command entries; these have been combined
+ *      into a single \c Event element which can be constructed using the new macro \ref MIDI_EVENT(). Existing applications should use the new macro and structure
+ *      element name.
+ *    - The library "LUFA/Drivers/USB/Core/ConfigDescriptor.c" source file has been renamed "LUFA/Drivers/USB/Core/ConfigDescriptors.c" as this was clashing with
+ *      files in some low level host mode demo applications, preventing parallel project builds. If you are referencing the project source files directly instead
+ *      of using the makefile module names, you will need to adjust your project makefile.

+ *      Existing applications should switch over to the correctly spelled macro names.
+ *    - The names of the USB Device and USB Host class driver files have changed; a new "ClassDevice" and "ClassHost" postfix has been added to the
+ *      respective class driver files. Projects referencing the class driver source files by filename rather than the LUFA_SRC_USBCLASS makefile
+ *      variable should append these postfixes to the source file names. Projects including the USB class driver dispatch headers directly should either
+ *      switch to including the main USB driver header instead, or use the updated header filenames.
+ *    - The USB_CONFIG_ATTR_BUSPOWERED constant has been renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed. All devices must set this bit in

+ *    - By default, unordered Endpoint and Pipe configuration is now allowed once again, via the previous workaround of
+ *      reconfiguring all Endpoints/Pipes in order each time a new Endpoint/Pipe is created. To minimize the compiled program
+ *      size, the new \c ORDERED_EP_CONFIG compile time option may be defined in the project makefile to restrict the ordering
+ *      in exchange for a smaller compiled binary size.
+ *    - The previous \c F_CLOCK symbol, required in the project makefile, has been renamed to \c F_USB. This is due to the previous name
+ *      being far too generic for use in future architecture ports, where multiple clock domains are used.
+ *
+ *  <b>Device Mode</b>
+ *    - The Endpoint stream functions now all require a \c BytesProcessed parameter instead of the previous callback parameter.

+ *      error code to allow the user application to determine when to send the next chunk of data.
+ *    - The \ref CDC_Device_SendString() function now expects a null terminated string instead of an explicit length. Existing code
+ *      should use the new \ref CDC_Device_SendData() function, or remove the length parameter from the function call.
+ *    - The \c Endpoint_ResetFIFO() function has been renamed to \ref Endpoint_ResetEndpoint(), to make the API function names more
+ *      consistent. Existing applications using the old function name should simply replace it with a call to the new function name.
+ *    - The \c Endpoint_*_Byte() functions have been renamed Endpoint_*_8() to ensure they are correct across all architectures. Existing

+ *      to \ref RNDIS_Device_ReadPacket() and/or \ref RNDIS_Device_SendPacket().
+ *    - The definition of the Audio class \ref USB_Audio_Descriptor_Format_t has been altered, to remove the fixed singular
+ *      audio sample rate in the descriptor definition, and to rename the \c SampleFrequencyType to the more appropriate
+ *      \c TotalDiscreteSampleRates. Existing applications will need to add an array of \ref USB_Audio_SampleFreq_t elements

+ *      \ref ENDPOINT_DIR_OUT to improve code clarity.
+ *    - The \ref HID_DESCRIPTOR_JOYSTICK() macro now takes an additional (first) parameter indicating the number of axis in the joystick.

+ *    - The \c Pipe_ClearErrorFlags() function has been removed, as the pipe error flags are now automatically cleared when the
+ *      \ref Pipe_ClearError() function is called.
+ *    - The \c Pipe_*_Byte() functions have been renamed Pipe_*_8() to ensure they are correct across all architectures. Existing code using

+ *    - The USB event names have been changed and their firing conditions changed to properly separate out Host mode events from Device mode
+ *      events. See the \ref Group_Events page for details on the new event names and firing conditions.
+ *
+ *  <b>Device Mode</b>
+ *    - The \ref CALLBACK_USB_GetDescriptor() function now takes an extra parameter to specify the descriptor's memory space so that
+ *      descriptors in mixed memory spaces can be used. The previous functionality can be returned by defining the \c USE_FLASH_DESCRIPTORS
+ *      token in the project makefile to fix all descriptors into FLASH space and remove the extra function parameter.
+ *    - The \c USB_IsSuspended global has been removed - test \ref USB_DeviceState against \ref DEVICE_STATE_Suspended instead.
+ *    - The \c USB_IsConnected global has been removed, as it is too vague for general use. Test \ref USB_DeviceState explicitly to ensure the device
+ *      is in the desired state instead.
+ *    - The VBUS events have been removed, as they are already exposed to the user via the \c USB_Connect and \c USB_Disconnect events.
+ *    - The USB event names have been changed and their firing conditions changed to properly separate out Host mode events from Device mode
+ *      events. See the \ref Group_Events page for details on the new event names and firing conditions.

+ *  <b>Device Mode</b>
+ *    - Support for non-control data endpoint interrupts has been dropped due to many issues in the implementation. All existing
+ *      projects using interrupts on non-control endpoints should switch to polling. For control interrupts, the library can
+ *      manage the control endpoint via interrupts automatically by compiling with the \c INTERRUPT_CONTROL_ENDPOINT token defined.
+ *    - The \c DESCRIPTOR_ADDRESS() macro has been removed. User applications should use normal casts to obtain a descriptor's memory
+ *      address.
+ *    - The library events system has been rewritten, so that all macros have been removed to allow for clearer user code. See
+ *      \ref Group_Events for new API details.
+ *    - The \c STREAM_CALLBACK() macro has been removed. User applications should replace all instances of the macro with regular
+ *      function signatures of a function accepting no arguments and returning a \c uint8_t value.
+ *    - The \c Event_DeviceError() event no longer exists, as its sole caller (unlinked \c USB_GetDescriptor() function) now produces a
+ *      compilation error rather than a runtime error. The \c StdDescriptors.c file no longer exists as a result, and should be removed
+ *      from project makefiles.
+ *    - The \c USB_GetDescriptor() function has been renamed to \ref CALLBACK_USB_GetDescriptor() to be in line with the new \c CALLBACK_
+ *      function prefixes for functions which <i>must</i> be implemented in the user application.
+ *

+ *  <b>Host Mode</b>
+ *    - The \ref USB_Host_SendControlRequest() function no longer automatically selects the Control pipe (pipe 0) to allow it to be used on
+ *      other control type pipes. Care should be taken to ensure that the Control pipe is always selected before the function is called
+ *      in existing projects where the Control pipe is to be operated on.
+ *    - The USB Host management task now saves and restores the currently selected pipe before and after the task runs. Projects no longer
+ *      need to manage this manually when calling the USB management task.
+ *    - The \c Pipe_ClearCurrentBank() macro has been removed, and is now replaced with the Pipe_ClearIN(), Pipe_ClearOUT() macros. See
+ *      Pipe.h documentation for more details on the new pipe management macros.
+ *    - The \c Pipe_ReadWriteAllowed() macro has been renamed to \ref Pipe_IsReadWriteAllowed() to be more consistent with the rest of the API

+ *    - The \c Pipe_Ignore_Word() and \c Pipe_Ignore_DWord() functions have been renamed to \c Pipe_Discard_Word() and \c Pipe_Discard_DWord()
+ *      to remain consistent with the rest of the pipe API.
+ *    - It is no longer needed to manually include the headers from \c LUFA/Drivers/USB/Class, as they are now included along with the rest
+ *      of the USB headers when \c LUFA/Drivers/USB/USB.h is included.
+ *    - Functions in the \c ConfigDescriptor.h header file no longer have \c Host_ as part of their names.

+ *
+ *  <b>Library Demos</b>
+ *    - The ReconfigureUSART() routine in the USBtoSerial demo was not being called after new line encoding

+ *    - The HID Parser now supports multiple report (on a single endpoint) HID devices. The MouseHostWithParser and
+ *      KeyboardHostWithPaser demos use the updated API functions to function correctly on such devices. Projects
+ *      built on either "WithParser" demo should update to the latest code.
+ *    - The RNDIS demo TCP stack has been modified so that connections can be properly closed. It is still not

+ *    - The MANUAL_PLL_CONTROL compile time token has been removed, and replaced with a USB_OPT_MANUAL_PLL mask
+ *      to be used in the Options parameter of the USB_Init() function.
+ *    - Calling USB_Init() now forces a complete USB interface reset and enumeration, even if the USB interface is
+ *      currently initialized.
+ *    - Interrupts are now disabled when processing control requests, to avoid problems with interrupts causing the library
+ *      or user request processing code to exceed the strict USB timing requirements on control transfers.
+ *    - The USB Reset event now resets and disables all device endpoints. If user code depends on endpoints remaining configured
+ *      after a Reset event, it should be altered to explicitly re-initialize all user endpoints.
+ *    - The prototype for the GetDescriptor function has been changed, as the return value was redundant. The function now
+ *      returns the size of the descriptor, rather than passing it back via a parameter, or returns NO_DESCRIPTOR if the specified
+ *      descriptor does not exist.
+ *    - The NO_DESCRIPTOR_STRING macro has been renamed NO_DESCRIPTOR, and is now also used as a possible return value for the
+ *      GetDescriptor function.

+ *      SetReportItemInfo() routines now return a boolean, set if the requested report item was located in the
+ *      current report. If sending a report to a multi-report device, the first byte of the report is automatically

+ *  \section Sec_Migration152 Migrating from V1.5.2 to V1.5.3
+ *
+ *  <b>Library Demos</b>
+ *    - Previously, all demos contained a serial number string descriptor, filled with all zeros. A serial number
+ *      string is required in Mass Storage devices, or devices which are to retain settings when moved between
+ *      ports on a machine. As people were not changing the serial number value, this was causing conflicts and so
+ *      the serial number descriptor has been removed from all but the Mass Storage demo, which requires it.
+ *    - The AudioOut and AudioIn demos did not previously silence their endpoints when the host has deactivated
+ *      them. Projects built upon either demo should upgrade to the latest code.
+ *    - The FEATURE_ENDPOINT macro has been renamed FEATURE_ENDPOINT_HALT, and is now correctly documented.
+ *    - The MassStoreHost demo contained errors which caused it to lock up randomly on certain devices. Projects built
+ *      on the MassStoreDemo code should update to the latest version.
+ *    - The Interrupt type endpoint in the CDC based demos previously had a polling interval of 0x02, which caused
+ *      problems on some Linux systems. This has been changed to 0xFF, projects built on the CDC demos should upgrade
+ *      to the latest code.
+ *    - The HID keyboard and mouse demos were not previously boot mode compatible. To enable boot mode support, projects
+ *      built on the keyboard or mouse demos (or derivatives) should upgrade to the latest code.
+ *    - The Mass Storage demo was not previously standards compliant. Projects built on the Mass Storage demo should
+ *      upgrade to the latest code.
+ *    - The USART was not being reconfigured after the host sent new encoding settings in the USBtoSerial demo. This was
+ *      previously discovered and fixed, but the change was lost. Projects built on the USBtoSerial demo should update
+ *      to the latest code.
+ *
+ *  <b>Device Mode</b>
+ *    - The endpoint non-control stream functions now have a default timeout of 50ms between packets in the stream.
+ *      If this timeout is exceeded, the function returns the new ENDPOINT_RWSTREAM_ERROR_Timeout error value. The
+ *      timeout value can be overridden by defining the USB_STREAM_TIMEOUT_MS in the project makefile to the desired
+ *      timeout duration in ms.
+ *    - Rather than returning fixed values, the flags indicating if the device has Remote Wakeup currently enabled
+ *      and/or is self-powered are now accessed and set through the new USB_RemoteWakeupEnabled and
+ *      USB_CurrentlySelfPowered macros. See the DevChapter9.h documentation for more details.
+ *    - All endpoint stream functions now require an extra Callback function parameter. Existing code may be updated
+ *      to either supply NO_STREAM_CALLBACK as the extra parameter, or disable stream callbacks altogether by passing
+ *      the token NO_STREAM_CALLBACKS to the compiler using the -D switch.
+ *
+ *  <b>Host Mode</b>
+ *    - The pipe non-control stream functions now have a default timeout of 50ms between packets in the stream.
+ *      If this timeout is exceeded, the function returns the new PIPE_RWSTREAM_ERROR_Timeout error value. The
+ *      timeout value can be overridden by defining the USB_STREAM_TIMEOUT_MS in the project makefile to the desired
+ *      timeout duration in ms.
+ *    - CollectionPath_t has been renamed to HID_CollectionPath_t to be more in line with the other HID parser structures.
+ *    - All pipe stream functions now require an extra Callback function parameter. Existing code may be updated

+ *  \section Sec_Migration151 Migrating from V1.5.1 to V1.5.2
+ *
+ *  <b>Library Demos</b>
+ *    - The RNDIS demo application has been updated so that it is functional on Linux under earlier implementations
+ *      of the RNDIS specification, which had non-standard behaviour. Projects built upon the demo should upgrade
+ *      to the latest code.
+ *    - The DFU class bootloader has had several bugs corrected in this release. It is recommended that where
+ *      possible any existing devices upgrade to the latest bootloader code.
+ *
+ *  \section Sec_Migration150 Migrating from V1.5.0 to V1.5.1
+ *
+ *  <b>Library Demos</b>
+ *    - The USBtoSerial demo was broken in the 1.5.0 release, due to incorrect register polling in place of the
+ *      global "Transmitting" flag. The change has been reverted in this release. Projects built upon the demo
+ *      should upgrade to the latest code.
+ *    - The HID class demos did not implement the mandatory GetReport HID class request. Projects built upon the HID
+ *      demos should upgrade to the latest code.
+ *    - The HID class demos incorrectly reported themselves as boot-protocol enabled HID devices in their descriptors.
+ *      Projects built upon the HID demos should upgrade to the latest code.
+ *    - The MIDI device demo had incorrect AudioStreaming interface descriptors. Projects built upon the MIDI demo
+ *      should upgrade to the latest code.
+ *    - The AudioOut demo did not correctly tristate the speaker pins when USB was disconnected, wasting power.
+ *      Projects built upon the AudioOut demo should upgrade to the latest code.
+ *
+ *  \section Sec_Migration141 Migrating from V1.4.1 to V1.5.0
+ *
+ *  <b>Library Demos</b>
+ *    - Previous versions of the library demos had incorrectly encoded BCD version numbers in the descriptors. To
+ *      avoid such mistakes in the future, the VERSION_BCD macro has been added to StdDescriptors.h. Existing
+ *      projects should at least manually correct the BCD version numbers, or preferably update the descriptors to
+ *      encode the version number in BCD format using the new macro.
+ *    - The mandatory GetReport class-specific request was accidentally omitted from previous versions of the demos
+ *      based on the Human Interface Device (HID) class. This has been corrected, and any user projects based on the
+ *      HID demos should also be updated accordingly.
+ *    - The CDC demos now correctly send an empty packet directly after a full packet, to end the transmission.
+ *      Failure to do this on projects which always or frequently send full packets will cause buffering issues on
+ *      the host OS. All CDC user projects are advised to update their transmission routines in the same manner as
+ *      the library CDC demos.
+ *    - The previous interrupt-driven Endpoint/Pipe demos did not properly save and restore the currently selected
+ *      Endpoint/Pipe when the ISR fired. This has been corrected - user projects based on the interrupt driven
+ *      demos should also update to properly save and restore the selected Endpoint/Pipe.
+ *
+ *  <b>Non-USB Library Components</b>
+ *    - The Atomic.h and ISRMacro.h header files in MyUSB/Common have been removed, as the library is now only
+ *      compatible with avr-libc library versions newer than the time before the functionality of the deleted
+ *      headers was available.
+ *
+ *  <b>Device Mode</b>
+ *    - The GetDescriptor function (see StdDescriptors.h) now has a new prototype, with altered parameter names and
+ *      functions. Existing projects will need to update the GetDescriptor implementation to reflect the new API.
+ *      The previously split Type and Index parameters are now passed as the original wValue parameter to the
+ *      function, to make way for the USB specification wIndex parameter which is <i>not</i> the same as the
+ *      previous Index parameter.
+ *    - The USB_UnhandledControlPacket event (see Events.h) now has new parameter names, to be in line with the
+ *      official USB specification. Existing code will need to be altered to use the new parameter names.
+ *    - The USB_CreateEndpoints event (see Events.h) has been renamed to USB_ConfigurationChanged, which is more
+ *      appropriate. It fires in an identical manner to the previously named event, thus the only change to be made
+ *      is the event name itself in the user project.
+ *    - The USB_Descriptor_Language_t structure no longer exists in StdDescriptors.h, as this was a
+ *      pseudo-descriptor modeled on the string descriptor. It is replaced by the true USB_Descriptor_String_t type
+ *      descriptor as indicated in the USB specification, thus all device code must be updated accordingly.
+ *    - The names of several Endpoint macros have been changed to be more consistent with the rest of the library,
+ *      with no implementation changes. This means that existing code can be altered to use the new macro names
+ *      with no other considerations required. See Endpoint.h for the new macro names.
+ *    - The previous version of the MassStorage demo had an incorrect value in the SCSI_Request_Sense_Response_t
+ *      structure named SenseData in SCSI.c which caused some problems with some hosts. User projects based on this
+ *      demo should correct the structure value to maintain compatibility across multiple OS platforms.
+ *    - By default, the descriptor structures use the official USB specification names for the elements. Previous
+ *      versions of the library used non-standard (but more verbose) names, which are still usable in the current
+ *      and future releases when the correct compile time option is enabled. See the StdDescriptors.h file
+ *      documentation for more details.
+ *
+ *  <b>Host Mode</b>
+ *    - The USB_Host_Request_Header_t structure in HostChapter9.h (used for issuing control requests) has had its
+ *      members renamed to the official USB specification names for requests. Existing code will need to be updated
+ *      to use the new names.
+ *    - The names of several Pipe macros have been changed to be more consistent with the rest of the library,
+ *      with no implementation changes. This means that existing code can be altered to use the new macro names
+ *      with no other considerations required. See Pipe.h for the new macro names.
+ *    - By default, the descriptor structures use the official USB specification names for the elements. Previous
+ *      versions of the library used non-standard (but more verbose) names, which are still usable in the current
+ *      and future releases when the correct compile time option is enabled. See the StdDescriptors.h file
+ *      documentation for more details.
+ *    - The names of the macros in Host.h for controlling the SOF generation have been renamed, see the Host.h
+ *      module documentation for the new macro names.
+ *
+ *  <b>Dual Role Mode</b>
+ *    - The OTG.h header file has been corrected so that the macros now perform their stated functions. Any existing
+ *      projects using custom headers to fix the broken OTG header should now be altered to once again use the OTG
+ *      header inside the library.
+ *    - The USB_DeviceEnumerationComplete event (see Events.h) now also fires in Device mode, when the host has
+ *      finished enumerating the device. Projects relying on the event only firing in Host mode should be updated
+ *      so that the event action only occurs when the USB_Mode global is set to USB_MODE_HOST.

+/** \page Page_ProgrammingApps Programming an Application into a USB AVR
+ *
+ *  Once you have built an application, you will need a way to program in the resulting ".HEX" file (and, if your
+ *  application uses EEPROM variables with initial values, also a ".EEP" file) into your USB AVR. Normally, the
+ *  reprogramming of an AVR device must be performed using a special piece of programming hardware, through one of the
+ *  supported AVR programming protocols - ISP, HVSP, HVPP, JTAG, dW or PDI. This can be done through a custom programmer,
+ *  a third party programmer, or an official Atmel AVR tool - for more information, see the <a>atmel.com</a> website.
+ *
+ *  Alternatively, you can use the bootloader. From the Atmel factory, each USB AVR comes preloaded with the Atmel
+ *  DFU (Device Firmware Update) class bootloader, a small piece of AVR firmware which allows the remainder of the
+ *  AVR to be programmed through a non-standard interface such as the serial USART port, SPI, or (in this case) USB.
+ *  Bootloaders have the advantage of not requiring any special hardware for programming, and cannot usually be erased
+ *  or broken without an external programming device. They have disadvantages however; they cannot change the fuses of
+ *  the AVR (special configuration settings that control the operation of the chip itself) and a small portion of the
+ *  AVR's FLASH program memory must be reserved to contain the bootloader firmware, and thus cannot be used by the
+ *  loaded application.
+ *
+ *  If you wish to use the DFU bootloader to program in your application, refer to your DFU programmer's documentation.
+ *  Atmel provides a free utility called FLIP which is USB AVR compatible, and an open source (Linux compatible)
+ *  alternative exists called "dfu-programmer".

+ *  \page Page_SoftwareBootloaderStart Entering the Bootloader via Software
+ *
+ *  A common requirement of many applications is the ability to jump to the programmed bootloader of a chip
+ *  on demand, via the code's firmware (i.e. not as a result of any physical user interaction with the
+ *  hardware). This might be required because the device does not have any physical user input, or simply
+ *  just to streamline the device upgrade process on the host PC.
+ *
+ *  The following C code snippets may be used to enter the bootloader upon request by the user application.
+ *  By using the watchdog to physically reset the controller, it is ensured that all system hardware is
+ *  completely reset to their defaults before the bootloader is run. This is important; since bootloaders
+ *  are written to occupy a very limited space, they usually make assumptions about the register states based
+ *  on the default values after a hard-reset of the chip.
+ *
+ *  \section Sec_SoftareBootAVR8 AVR8 Architecture

+/** \page Page_WritingBoardDrivers Writing LUFA Board Drivers
+ *
+ *  LUFA ships with several basic pre-made board drivers, to control hardware present on the supported board
+ *  hardware - such as Dataflash ICs, LEDs, Joysticks, or other hardware peripherals. When compiling an application
+ *  which makes use of one or more board drivers located in <i>LUFA/Drivers/Board</i>, you must also indicate which
+ *  board hardware you are using in your project makefile. This is done by defining the <tt>BOARD</tt> macro using
+ *  the <tt>-D</tt> switch passed to the compiler, with a constant of <tt>BOARD_{Name}</tt>. For example,
+ *  <tt>-DBOARD=BOARD_USBKEY</tt> instructs the compiler to use the USBKEY board hardware drivers.
+ *
+ *  If your application does not use <i>any</i> board level drivers, you can omit the definition of the <tt>BOARD</tt>
+ *  macro. However, some users may wish to write their own custom board hardware drivers which are to remain compatible
+ *  with the LUFA hardware API. To do this, the <tt>BOARD</tt> macro should be defined to the value <tt>BOARD_USER</tt>.
+ *  This indicates that the board level drivers should be located in a folder named "Board" located inside the
+ *  application's folder.
+ *
+ *  When used, the driver stub files located in the <tt>LUFA/CodeTemplates/DriverStubs</tt> folder should be copied to
+ *  the user application's <tt>Board/</tt> directory, and filled out to include the values and code needed to control
+ *  the custom board hardware. Once done, the existing LUFA board level APIs (accessed in the regular
+ *  <tt>LUFA/Drivers/Board/</tt> folder) will redirect to the user board drivers, maintaining code compatibility and
+ *  allowing for a different board to be selected through the project makefile with no code changes.
