3 # WinAVR Makefile Template written by Eric B. Weddington, Jg Wunsch, et al.
5 # Released to the Public Domain
7 # Additional material for this makefile was written by:
17 #----------------------------------------------------------------------------
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, using avrdude.
29 # Please customize the avrdude settings below first!
31 # make debug = Start either simulavr or avarice as specified for debugging,
32 # with avr-gdb or avr-insight as the front end for debugging.
34 # make filename.s = Just compile filename.c into the assembler code only.
36 # make filename.i = Create a preprocessed source file for use in submitting
37 # bug reports to the GCC project.
39 # To rebuild project do "make clean" then "make all".

49 # this an empty or blank macro!

60 # Native formats for AVR-GCC's -g are dwarf-2 [default] or stabs.
61 # AVR Studio 4.10 requires dwarf-2.
62 # AVR [Extended] COFF format requires stabs, plus an avr-objcopy run.
