# Hey Emacs, this is a -*- makefile -*-

#
|

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

# Released to the Public Domain

# Please read the make user manual!

#
|

# Additional material for this makefile was submitted by:

# Peter Fleury

# Reiner Patommel
|

# Sander Pool
|

# Frederik Rouleau
|

# Markus Pfaff
|

#
|

# On command line:
|
||||
#
|
||||
# make all = Make software.
|
||||
#
|
||||
# make clean = Clean out built project files.
|
||||
#
|
||||
# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).
|
||||
#
|
||||
# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
|
||||
# 4.07 or greater).
|
||||
#
|
||||
# make program = Download the hex file to the device, using avrdude. Please
|
||||
# customize the avrdude settings below first!
|

#
|

# make filename.s = Just compile filename.c into the assembler code only
