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

# WinAVR makefile written by Eric B. Weddington, J<>rg Wunsch, et al.

# Released to the Public Domain

# Additional material for this makefile was submitted by:

|

# 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
