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

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

  64 # Processor frequency.

  67 #     calculate timings. Do NOT tack on a 'UL' at the end, this will be done

  70 #     This will be an integer division of F_USB below, as it is sourced by
  71 #     F_USB after it has run through any CPU prescalers. Note that this value
  72 #     does not *change* the processor frequency - it should merely be updated to

  80 #     input clock frequency (before any prescaling is performed) in Hz. This value may
  81 #     differ from F_CPU if prescaling is used on the latter, and is required as the
  82 #     raw input clock is fed directly to the PLL sections of the AVR for high speed
  83 #     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
  84 #     at the end, this will be done automatically to create a 32-bit value in your
  85 #     source code.
