See keymap.c. + + +PS/2 signal handling implementations +------------------------------------ +Following three methods are used to implement PS/2 signal handling. +a. Simple and stupid wait & read loop(intensive use of cycles) + This is implemented with (expected) portable C code for reference. See ps2.c. +b. Interrupt driven + See ps2_intr.c +c. Using USART hardware module(no cycle needed) + This uses AVR USART function to recevie PS/2 signal and be used in V-USB converter. + See ps2_usart.c. + + +Build Converter +--------------- +Connect PS/2 keyboard into Teensy with 4 lines(Vcc, GND, Data, Clock). +For a. Simple and stupid and b. Interrupt implementaion: + By default Clock is on PF0 and Data on PF1. + You can change this pin configuration by editing config_pjrc.h. + In this photo Vcc is yellow, GND is green, Data is red and Clock is black. + http://img17.imageshack.us/img17/7243/201101181933.jpg +For c. USART implementation: + In case of Teensny(ATMega32u4) CLock is on PD5 and Data on PD2. + + +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.pjrc_intr' option to use b. Interrupt. + Use '-f Makefile.pjrc_usart' option to use c. USART. + Use '-f Makefile.vusb' option to build V-USB converter. +3. program with Teensy Loader. + http://www.pjrc.com/teensy/loader.html + + +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.c like following. +How to define the keymap is probably obvious. You can find key symbols in usb_keycodes.h. +To define keymap layer switching may needs a bit of your effort at this time. + + /* Default Layer: plain keymap + * ,---. ,---------------. ,---------------. ,---------------. ,-----------. ,-----------. + * |Esc| |F1 |F2 |F3 |F4 | |F5 |F6 |F7 |F8 | |F9 |F10|F11|F12| |PrS|ScL|Pau| |Pwr|Slp|Wak| + * `---' `---------------' `---------------' `---------------' `-----------' `-----------' + * ,-----------------------------------------------------------. ,-----------. ,---------------. + * | `| 1| 2| 3| 4| 5| 6| 7| 8| 9| 0| -| =|Backspa| |Ins|Hom|PgU| |NmL| /| *| -| + * |-----------------------------------------------------------| |-----------| |---------------| + * |Tab | Q| W| E| R| T| Y| U| I| O| P| [| ]| \| |Del|End|PgD| | 7| 8| 9| | + * |-----------------------------------------------------------| `-----------' |-----------| +| + * |CapsLo| A| S| D| F| G| H| J| K| L| ;| '|Return | | 4| 5| 6| | + * |-----------------------------------------------------------| ,---. |---------------| + * |Shift | Z| X| C| V| B| N| M| ,| ,| /|Shift | |Up | | 1| 2| 3| | + * |-----------------------------------------------------------| ,-----------. |-----------|Ent| + * |Ctrl |Gui |Alt | Space |Alt |Gui |Menu|Ctrl| |Lef|Dow|Rig| | 0| .| | + * `-----------------------------------------------------------' `-----------' `---------------' + */ + KEYMAP( + ESC, F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, PSCR,SLCK,BRK, PWR, F13, F14, + GRV, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, MINS,EQL, BSPC, INS, HOME,PGUP, NLCK,PSLS,PAST,PMNS, + TAB, Q, W, E, R, T, Y, U, I, O, P, LBRC,RBRC,BSLS, DEL, END, PGDN, P7, P8, P9, + CAPS,A, S, D, F, G, H, J, K, L, SCLN,QUOT, ENT, P4, P5, P6, PPLS, + LSFT,Z, X, C, V, B, N, M, COMM,DOT, SLSH, RSFT, UP, P1, P2, P3, + LCTL,LGUI,LALT, SPC, RALT,RGUI,APP, RCTL, LEFT,DOWN,RGHT, P0, PDOT,PENT + ), + + +EOF |
