6 # Released to the Public Domain
8 # Additional material for this makefile was written by:
21 #----------------------------------------------------------------------------
24 # make all = Make software.
26 # make clean = Clean out built project files.
28 # make coff = Convert ELF to AVR COFF.
30 # make extcoff = Convert ELF to AVR Extended COFF.
32 # make program = Download the hex file to the device, using avrdude.
33 # Please customize the avrdude settings below first!
35 # make doxygen = Generate DoxyGen documentation for the project (must have
38 # make debug = Start either simulavr or avarice as specified for debugging,
39 # with avr-gdb or avr-insight as the front end for debugging.
41 # make filename.s = Just compile filename.c into the assembler code only.
43 # make filename.i = Create a preprocessed source file for use in submitting
44 # bug reports to the GCC project.
46 # To rebuild project do "make clean" then "make all".

55 # LUFA board drivers). If USER is selected, put custom board drivers in a directory called
56 # "Board" inside the application directory.
60 # Processor frequency.
61 # This will define a symbol, F_CPU, in all source code files equal to the
62 # processor frequency. You can then use this symbol in your source code to
63 # calculate timings. Do NOT tack on a 'UL' at the end, this will be done
64 # automatically to create a 32-bit value in your source code.
81 # Input clock frequency.
82 # This will define a symbol, F_CLOCK, in all source code files equal to the
83 # input clock frequency (before any prescaling is performed). This value may
84 # differ from F_CPU if prescaling is used on the latter, and is required as the
85 # raw input clock is fed directly to the PLL sections of the AVR for high speed
86 # clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
87 # at the end, this will be done automatically to create a 32-bit value in your
90 # If no clock division is performed on the input clock inside the AVR (via the
91 # CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
