# WinAVR Makefile Template written by Eric B. Weddington, J?rg Wunsch, et al.

#

# Released to the Public Domain

#

# Additional material for this makefile was written by:

# Peter Fleury

# Tim Henigan

# Colin O'Flynn

# Reiner Patommel

# Markus Pfaff

# Sander Pool

# Frederik Rouleau

#

#----------------------------------------------------------------------------

# 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".
