# WinAVR Sample makefile written by Eric B. Weddington, et al.
# Released to the Public Domain
# Please read the make user manual!
#
#
# On command line:
# make all = Make software.
# make clean = Clean out built project files.
# make coff = Convert ELF to COFF using objtool.
#
# To rebuild project do "make clean" then "make all".
#

# MCU name
MCU = atmega128

# Output format. (can be srec, ihex)
FORMAT = ihex

# Target file name (without extension).
TARGET = main

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

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