  28 # make coff = Convert ELF to AVR COFF.

  32 # make program = Download the hex file to the device, using avrdude.

  35 # make doxygen = Generate DoxyGen documentation for the project (must have

  60 # Processor frequency.
  61 #     This will define a symbol, F_CPU, in all source code files equal to the
  62 #     processor frequency in Hz. 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 #
  66 #     This will be an integer division of F_CLOCK below, as it is sourced by
  67 #     F_CLOCK after it has run through any CPU prescalers. Note that this value
  68 #     does not *change* the processor frequency - it should merely be updated to
  69 #     reflect the processor speed set externally so that the code can use accurate
  70 #     software delays.

  74 # Input clock frequency.
  75 #     This will define a symbol, F_CLOCK, in all source code files equal to the
  76 #     input clock frequency (before any prescaling is performed) in Hz. This value may
  77 #     differ from F_CPU if prescaling is used on the latter, and is required as the
  78 #     raw input clock is fed directly to the PLL sections of the AVR for high speed
  79 #     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
  80 #     at the end, this will be done automatically to create a 32-bit value in your
  81 #     source code.
  82 #
  83 #     If no clock division is performed on the input clock inside the AVR (via the
