  28 # make coff = Convert ELF to AVR COFF.

  30 # make extcoff = Convert ELF to AVR Extended COFF.
  31 #
  32 # make program = Download the hex file to the device, using avrdude.
  33 #                Please customize the avrdude settings below first!
  34 #
  35 # make doxygen = Generate DoxyGen documentation for the project (must have
  36 #                DoxyGen installed)
  37 #
  38 # make debug = Start either simulavr or avarice as specified for debugging,

  41 # make filename.s = Just compile filename.c into the assembler code only.
  42 #
  43 # make filename.i = Create a preprocessed source file for use in submitting

  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.
  65 #     Typical values are:
  66 #         F_CPU =  1000000
  67 #         F_CPU =  1843200
  68 #         F_CPU =  2000000
  69 #         F_CPU =  3686400
  70 #         F_CPU =  4000000
  71 #         F_CPU =  7372800
  72 #         F_CPU =  8000000
  73 #         F_CPU = 11059200
  74 #         F_CPU = 14745600
  75 #         F_CPU = 16000000
  76 #         F_CPU = 18432000

  78 F_CPU = 8000000

  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
  88 #     source code.
  89 #
  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.
