1ADB to USB keyboard converter
2=============================
3
4This firmware converts ADB keyboard protocol to USB.
5
6Build
7-----
80. Connect ADB keyboard to Teensy by 3 lines(Vcc, GND, Data).
9 PSW line is optional. See ADB.txt for details.
101. Define following macros for ADB connection in config.h:
11 ADB_PORT
12 ADB_PIN
13 ADB_DDR
14 ADB_DATA_BIT
15 ADB_PSW_BIT
162. make
173. program Teensy.
