ADB to USB keyboard converter

=============================
http://geekhack.org/showwiki.php?title=Island:14290

This firmware converts ADB keyboard protocol to USB.


Build
-----
0. Connect ADB keyboard to Teensy by 3 lines(Vcc, GND, Data).
You need a external pull-up resistor on DATA line in most case,
in particular when you want to use a long or coiled cable.
This converter uses AVR's internal pull-up, but it seems to be too weak.
The external pull-up resistor is strongly recommended.
PSW line is optional. See ADB.txt for details.
1. Define following macros for ADB connection in config.h:
ADB_PORT
ADB_PIN
ADB_DDR
ADB_DATA_BIT
ADB_PSW_BIT
2. make
3. program Teensy.


Keymap
------
You can change a keymap by editing code of keymap.c like following.
This is a keymap for AEK, however, also used for other keyboards.
How to define the keymap is probably obvious. You can find key
symbols in usb_keycodes.h.
If you want to define some keymaps than just one, see hhkb/keymap.c and
macway/keymap.c as examples. Keymap(layer) switching may needs a bit of
effort at this time.
