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

# Released to the Public Domain

#
#----------------------------------------------------------------------------
# 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".
