#
#----------------------------------------------------------------------------
# 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".

# Processor frequency.
# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency. You can then use this symbol in your source code to
# calculate timings. Do NOT tack on a 'UL' at the end, this will be done
# automatically to create a 32-bit value in your source code.

# 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.
