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.
