- 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`.
-

-
- - M0110A support was contributed by [skagon@github](https://github.com/skagon).
- - M0120 also is supported. keys(+ * / and ,) on M0120 are recognized as cursor keys.
-
-
-
- Update
- ------
- - 2013/08 Change port for signals PF to PD
-
-
-
- Connection
- ----------
- You need 4P4C plug and cable to connect Teensy or other AVR dev board into the keyboard.
- Teensy port `PD0` is assigned for `CLOCK` line and `PD1` 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*.

- 1. `GND`(Black)
- 2. `CLOCK`(Red)
- 3. `DATA`(Green)
- 4. `+5V`(Yellow)
-
- Note that wire colors may vary in your cable.

-
-
- ### 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 clean
- $ make -f Makefile
-
- and program your Teensy with [PJRC Teensy loader](http://www.pjrc.com/teensy/loader.html).
-
-
-
- Keymap
- ------
- You can change keymaps by editing *keymap.c*.

- 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 `<magickey>+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)
