M0110/M0110A to USB keyboard converter
|
|
======================================
|
|
This firmware converts the protocol of Apple Macintosh keyboard **M0110**, **M0110A** and **M0120** into USB. Target of this project is USB AVR controller like **ATmega32U2** and **ATmega32U4**. Using this converter you can revive these retro keyboards with modern computer.
|
|
|
|
Read README of top directory too.
|
|
|
|
Pictures of **M0110 + M0120** and **M0110A** with [TMK converter].

|
|
|
|
|
|
- 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`
|
|
- 2013/09: Change port again, it uses inversely `PD0` for data and `PD1` for clock line now.
|
|
- 2014/06: Change keymaps
|
|
- 2015/03: Add support for "International"(ISO) keyboard(keymap_intl.c)
|
|
- 2016/09: Unimap support - keymap editor on web browser
|
|
- 2024/01: Add Keymap Editor support for International layout
|

Hardware
|
|
--------
|
|
You can buy preassembled [TMK converter] or make yourown with AVR dev board like PJRC [Teensy].
|
|
|
|
Port of the MCU `PD1` is assigned to `CLOCK` line and `PD0` to `DATA` by default, you can change pin configuration with editing `config.h`.

### 4P4C phone handset cable
|
|
Note that original cable used with Mac is **straight** while phone handset cable is **crossover**.

|
|
|
|
### Pull-up Resistor
|
|
You may need pull-up resistors on signal lines(`CLOCK`, `DATA`) in particular when you have long or coiled cable. **1k-10k Ohm** will be OK for this purpose. In that case the converter may not read signal from keyboard correctly without pull-up resistors.

Building Firmware
|
|
-----------------
|
|
To compile firmware you need AVR GCC. 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.unimap.rev2 clean
|
|
$ make -f Makefile.unimap.rev2
|
|
|
|
Use `Maefile.unimap.rev1` for TMK converter rev.1 and Teensy(ATMega32u4), instead.
|
|
|
|
|
|
### Keymap file
|
|
To create your own keymap copy `unimap.c` to `unimap_<name>.c` and edit it. You can build firmware like below:
|
|
|
|
$ make -f Makefile.unimap.rev2 KEYMAP=<name>
|
|
|
|
|
|
|
|
Keymap Editor
|
|
-------------
|
|
You can edit your keymap on Keymap Editor and download firmware.

### International layout
|

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 `<Magic>+H` simultaneously to get help.
|
|
|
|
- Magic combo: `Shift+Option+⌘` or `Shift+Option+Ctrl`(`Shift+Alt+Gui` or `Shift+Alt+Control`)
