See keymap.c. - - -PS/2 signal handling implementations ------------------------------------- -Following three methods are used to implement PS/2 signal handling. -a. Simple and stupid busy-wait(ps2.c) - This is expected to implemented with portable C code for reference. -b. Interrupt driven(ps2.c) - Uses external interrupt to detect falling edge of clock line. -c. USART hardware module(ps2_usart.c) - Uses AVR USART engine to recevie PS/2 signal. Recomended and default. - This is required to work with V-USB, preceding two methods tend to - miss signal edges while V-USB handles USB. - -To select method edit Makefile. - - -Connect Wires -------------- -In case of Teensy2.0(ATMega32U4): -0. Connect Vcc and GND. -1. Connect Clock and Data line. - For a. Clock is on PF0 and Data on PF1. - For b. Clock is on PD1 and Data on PD2. - For c. Clock is on PD5 and Data on PD2. -2. Optionally you need pull-up register. 1K-10K Ohm is OK. - -To change pin configuration edit config.h. - - -Build Frimware --------------- -1. Edit Makefile for build options and MCU setting. - Use 'atmega32u4' for Teensy 2.0 or 'at90usb1286' for Teensy++ 2.0. -2. make - Just type `make` in a terminal. - Use `-f Makefile.vusb` option to build V-USB converter. - Use `-f Makefile.jis` option to use JIS keyboard. -3. program MCU. - In case of Teensy use `Teensy Loader`.(http://www.pjrc.com/teensy/loader.html) - Otherwise you want to use `avrdude` or `dfu-programmer`. - - -Demonstration of Features -------------------------- -In default configuration, you can try several keymaps, mousekeys and USB NKRO. -Use following magic key combinations to enable some features. - -keymaps and NKRO: - Magic+0: Qwerty with mousekeys(default) - Magic+1: Qwerty without mousekeys - Magic+2: Colemak - Magic+3: Dvorak - Magic+4: Workman - Magic+N: toggles NKRO/6KRO(6KRO by default) - Magic+Esc: sends Power Event(Power button) - - where Magic=(LShift+RShift) or (LControl+RShift) - -Fn layer function: - Fn0+(hjkl): Mousekey move(vi cursor like) - Fn0+(yuio): Mouse wheel(left,down,up,right) - Fn0+space: Mouse left button - Fn0+(mnb): Mouse buttons(m=left, n=right, b=middle) - Fn0+(zxc): Media control(Volup, Voldown, Mute) - Fn1+(hjkl): Cursor move(vi cursor like) - Fn1+(nm,.): Cursor move(Home,PageDown,PageUp,End) - - where Fn0=;, Fn1=/ - - -Keymap ------- -You can change a keymap by editing code of keymap. See common/keycode.h for key symbols. - - -V-USB Support -------------- -You can also use this converter on ATmega(168/328) with V-USB instead of Teensy. -The converter on V-USB lacks some features for now: USB NKRO and System/Media control. - -Circuit -------- - +---+ +---------------+ -USB GND | | ATmega168 | -=== C3 | | -5V <-------+--------+---|Vcc,AVCC | PS/2 - R1 | | ==== -D- <----+--+-----R2-----|INT1 RXD|------->DATA -D+ <----|---+----R3-----|INT0 XCK|------->CLOCK - Z1 Z2 | | ->5V -GND<----+---+--+--+-----|GND | ->GND - | | | | - | C2-+--|XTAL1 | - | X1 | | - +--C3-+--|XTAL2 | - +---------------+ -R1: 1.5K Ohm -R2,R3: 68 Ohm -Z1,Z2: Zenner 3.6V -C1,C2: 22pF -C3: 0.1uF -X1: Crystal 20MHz(16MHz/12MHz) - - -EOF |
