ADB to USB keyboard converter
|
||||
=============================
|
||||
|
||||
This firmware converts ADB keyboard protocol to USB.
|
||||
|
||||
Build
|
||||
-----
|
||||
0. Connect ADB keyboard to Teensy by 3 lines(Vcc, GND, Data).
|
||||
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.
