# WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.

#----------------------------------------------------------------------------
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# make coff = Convert ELF to AVR COFF.
#
# make extcoff = Convert ELF to AVR Extended COFF.
#
# make program = Download the hex file to the device, using avrdude.
# Please customize the avrdude settings below first!
#
# make debug = Start either simulavr or avarice as specified for debugging,
# with avr-gdb or avr-insight as the front end for debugging.
#
# make filename.s = Just compile filename.c into the assembler code only.
#
# make filename.i = Create a preprocessed source file for use in submitting
# bug reports to the GCC project.
#
# To rebuild project do "make clean" then "make all".

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.
