M0110/M0110A to USB keyboard converter ====================================== This firmware converts the protocol of Apple Macintosh keyboard M0110/M0110A into USB. Target board of this project is [PJRC Teensy](http://www.pjrc.com/teensy/), though, you can use other board with USB AVR like `ATmega32U4` and `AT90USB`. ![M0110](https://raw.github.com/tmk/tmk_keyboard/master/converter/m0110_usb/doc/m0110.jpg) - M0110A support was contributed by [skagon@github](https://github.com/skagon). - M0120 also is supported. keys(+ * / and ,) on M0120 are recognized as cursor keys. Connection ---------- You need 4P4C plug and cable to connect Teensy or other AVR dev board into the keyboard. Teensy port `PF0` is assigned for `CLOCK` line and `PF1` for `DATA` by default, you can change pin configuration with editing *config.h*. You can find 4P4C plugs on telephone handset cable. Note that it is *crossover* connection while Macintosh keyboard cable is *straight*. [![Conection](https://raw.github.com/tmk/tmk_keyboard/master/converter/m0110_usb/doc/teensy.jpg)] In this pic: 1. `GND`(Black) 2. `CLOCK`(Red) 3. `DATA`(Green) 4. `+5V`(Yellow) Note that wire colors may vary in your cable. ### Pinout - - ![Jack fig](http://www.kbdbabel.org/conn/kbd_connector_macplus.png) ### Pull-up Registor You may need pull-up registors on signal lines(`CLOCK`, `DATA`) in particular when you have long or coiled cable. 1k-10k Ohm will be OK for this purpose. In some cases MCU can't read signal from keyboard correctly without pull-up resistors. Building Frimware ----------------- To compile firmware you need AVR GCC. You can use [WinAVR](http://winavr.sourceforge.net/) on Windows. You can edit *Makefile* and *config.h* to change compile options and pin configuration. $ git clone git://github.com/tmk/tmk_keyboard.git (or download source) $ cd m0110_usb $ make -f Makefile.lufa clean $ make -f Makefile.lufa and program your Teensy with [PJRC Teensy loader](http://www.pjrc.com/teensy/loader.html). Keymap ------ You can change keymaps by editing *keymap.c*. ### M0110 & M0120 #### *Default* ,---------------------------------------------------------. ,---------------. | `| 1| 2| 3| 4| 5| 6| 7| 8| 9| 0| -| =|Backs| |Ctl| -|Lft|Rgt| |---------------------------------------------------------| |---------------| |Tab | Q| W| E| R| T| Y| U| I| O| P| [| ]| \| | 7| 8| 9| Up| |---------------------------------------------------------| |---------------| |Fn0 | A| S| D| F| G| H| J| K| L| ;| '|Return| | 4| 5| 6| Dn| |---------------------------------------------------------| |---------------| |Shift | Z| X| C| V| B| N| M| ,| ,| /|Shift | | 1| 2| 3| | `---------------------------------------------------------' |-----------|Ent| |Ctl|Alt | Space |Gui |Ctl| | 0| .| | `-----------------------------------------------' `---------------' #### *HHKB/WASD Layer(WASD/IJKL)* ,---------------------------------------------------------. ,---------------. |Esc| F1| F2| F3| F4| F5| F6| F7| F8| F9|F10|F11|F12|Delet| |Nlk| -|Lft|Rgt| |---------------------------------------------------------| |---------------| |Caps |Hom| Up|PgU| | | |PgU| Up|Hom|Psc|Slk|Pau|Ins| | 7| 8| 9| Up| |---------------------------------------------------------| |---------------| |Fn0 |Lef|Dow|Rig| | | |Lef|Dow|Rig| | |Return| | 4| 5| 6| Dn| |---------------------------------------------------------| |---------------| |Shift |End| |PgD| | | |PgD| |End| |Shift | | 1| 2| 3| | `---------------------------------------------------------' |-----------|Ent| |Ctl|Alt | Space |Gui |Ctl| | 0| .| | `-----------------------------------------------' `---------------' ### M0110A #### *Default* ,---------------------------------------------------------. ,---------------. | `| 1| 2| 3| 4| 5| 6| 7| 8| 9| 0| -| =|Backs| |Ctl| =| /| *| |---------------------------------------------------------| |---------------| |Tab | Q| W| E| R| T| Y| U| I| O| P| [| ]| | | 7| 8| 9| -| |-----------------------------------------------------' | |---------------| |Fn0 | A| S| D| F| G| H| J| K| L| ;| '|Return| | 4| 5| 6| +| |---------------------------------------------------------| |---------------| |Shift | Z| X| C| V| B| N| M| ,| ,| /|Shft| Up| | 1| 2| 3| | |---------------------------------------------------------| |-----------|Ent| |Alt |Gui | Space | \|Lft|Rgt| Dn| | 0| .| | `---------------------------------------------------------' `---------------' #### *Cursor Layer(WASD/IJKL)* ,---------------------------------------------------------. ,---------------. |Esc| F1| F2| F3| F4| F5| F6| F7| F8| F9|F10|F11|F12|Delet| |Nlk| =| /| *| |---------------------------------------------------------| |---------------| |Caps |Hom| Up|PgU| | | |PgU| Up|Hom|Psc|Slk|Pau| | | 7| 8| 9| -| |-----------------------------------------------------' | |---------------| |Fn0 |Lef|Dow|Rig| | | |Lef|Dow|Rig| | |Return| | 4| 5| 6| +| |---------------------------------------------------------| |---------------| |Shift |End| |PgD| | | |PgD| |End| |Shif|PgU| | 1| 2| 3| | |---------------------------------------------------------| |-----------|Ent| |Alt |Gui | Space |Ins|Hom|End|PgD| | 0| .| | `---------------------------------------------------------' `---------------' Debug ----- You can use [PJRC HID listen](http://www.pjrc.com/teensy/hid_listen.html) to see debug output. The converter has some functions for debug, press `+H` simultaneously to get help. These function is totally undocumented, tentative, inconsistent and buggy. magickey: Shift+Option+Command(Shift+Alt+Gui or Shift+Alt+Control)
