| - | NOTE: There currently is a problem with the code on the ATmega168, please use the ATmega8 for now. They are pin compatible chips, so if you use the ATmega8 you can always replace it with an ATmega168 later. There are two Makefile changes that need to be made when you compile the code. These changes as well as a working hex file for the ATmega8 are at: [[.:using_the_atmega8]]--- //[[priestdo@cs.vassar.edu|Greg Priest-Dorman]] 2009/05/04 09:50// | + | ===== Bill of Materials ===== |
