annotate Makefile.avr @ 32:b0cb873c0206

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Isolate the bus frobbing parts and the delays into a separate header. This means the user only has to edit a single file to suit their situation and allows the code to work with active drive systems as well as passive pullups (ie 1 vs 2 IO pins)
