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.
