3 # AVR-GCC Makefile template, derived from the WinAVR template (which
4 # is public domain), believed to be neutral to any flavor of "make"
5 # (GNU make, BSD make, SysV make)

7 # Adaptations by Jon Langseth <jon.langseth AT lilug.no>

20 # processor frequency. You can then use this symbol in your source code to
21 # calculate timings. Do NOT tack on a 'UL' at the end, this will be done
22 # automatically to create a 32-bit value in your source code.
23 # Typical values are:
24 # F_CPU = 1000000
25 # F_CPU = 1843200
