  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".

  54 # Target architecture (see library "Board Types" documentation).
 
  58 # Target board (see library "Board Types" documentation, NONE for projects not requiring
 
  59 # LUFA board drivers). If USER is selected, put custom board drivers in a directory called
 
  60 # "Board" inside the application directory.
 
  64 # Processor frequency.
 
  65 #     This will define a symbol, F_CPU, in all source code files equal to the
 
  66 #     processor frequency in Hz. You can then use this symbol in your source code to
 
  67 #     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
 
  68 #     automatically to create a 32-bit value in your source code.
 
  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
 
  73 #     reflect the processor speed set externally so that the code can use accurate
 
  78 # Input clock frequency.
 
  79 #     This will define a symbol, F_USB, in all source code files equal to the
 
  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
 
  87 #     If no clock division is performed on the input clock inside the AVR (via the
 
  88 #     CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
