20 # make all = Make software.
22 # make clean = Clean out built project files.
24 # make coff = Convert ELF to AVR COFF.
26 # make extcoff = Convert ELF to AVR Extended COFF.
28 # make program = Download the hex file to the device.
29 # Please customize your programmer settings(PROGRAM_CMD)
31 # make teensy = Download the hex file to the device, using teensy_loader_cli.
32 # (must have teensy_loader_cli installed).
34 # make dfu = Download the hex file to the device, using dfu-programmer (must
35 # have dfu-programmer installed).
37 # make flip = Download the hex file to the device, using Atmel FLIP (must
38 # have Atmel FLIP installed).

47 # with avr-gdb or avr-insight as the front end for debugging.
49 # make filename.s = Just compile filename.c into the assembler code only.
51 # make filename.i = Create a preprocessed source file for use in submitting
52 # bug reports to the GCC project.
54 # To rebuild project do "make clean" then "make all".
