1 ###| CMAKE Kiibohd Controller |###
3 # Written by Jacob Alexander in 2011 for the Kiibohd Controller
4 # Due to this file's usefulness:
6 # Released into the Public Domain
11 # - Add avr-gcc as requirement
12 # - Add avr-objcopy as a requirement
13 # - Generate .lst files
14 # - Extend .lst to .lss
15 # - Autoloader to Teensy
16 # - specify on commandline which atmel mcu

98 #| examples use this variable to calculate timings. Do not add a "UL" here.
