# AVR Sample makefile written by Eric B. Weddington, Jörg Wunsch, et al.
# Modified (bringing often-changed options to the top) by Elliot Williams
# make all = Make software and program
# make clean = Clean out built project files.
# make program = Download the hex file to the device, using avrdude. Please
# customize the avrdude settings below first!
# Microcontroller Type
MCU = atmega1284p
# Target file name (without extension).
TARGET = images/OpenModem
# Programming hardware: type avrdude -c ?
# to get a full listing.

# (Note: 3 is not always the best optimization level. See avr-libc FAQ.)

# List C source files here. (C dependencies are automatically generated.)
#SRC = $(TARGET).c

# If there is more than one source file, append them above, or modify and
# uncomment the following:
#SRC += foo.c bar.c
# You can also wrap lines by appending a backslash to the end of the line:
#SRC += baz.c \\
#xyzzy.c
# List Assembler source files here.
# Make them always end in a capital .S. Files ending in a lowercase .s
# will not be considered source files but generated files (assembler
# output from the compiler), and will be deleted upon "make clean"!
# Even though the DOS/Win* filesystem matches both .s and .S the same,
# it will preserve the spelling of the filenames, and gcc itself does
# care about how the name is spelled on its command-line.
