6 # Released to the Public Domain
8 # Additional material for this makefile was written by:

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 dfu = Download the hex file to the device, using dfu-programmer (must
36 # have dfu-programmer installed).
38 # make flip = Download the hex file to the device, using Atmel FLIP (must
39 # have Atmel FLIP installed).
41 # make dfu-ee = Download the eeprom file to the device, using dfu-programmer
42 # (must have dfu-programmer installed).
44 # make flip-ee = Download the eeprom file to the device, using Atmel FLIP
45 # (must have Atmel FLIP installed).
47 # make doxygen = Generate DoxyGen documentation for the project (must have
50 # make debug = Start either simulavr or avarice as specified for debugging,
51 # with avr-gdb or avr-insight as the front end for debugging.
53 # make filename.s = Just compile filename.c into the assembler code only.
55 # make filename.i = Create a preprocessed source file for use in submitting
56 # bug reports to the GCC project.
58 # To rebuild project do "make clean" then "make all".

66 # Target architecture (see library "Board Types" documentation).
70 # Target board (see library "Board Types" documentation, NONE for projects not requiring
71 # LUFA board drivers). If USER is selected, put custom board drivers in a directory called
72 # "Board" inside the application directory.
76 # Processor frequency.
77 # This will define a symbol, F_CPU, in all source code files equal to the
78 # processor frequency in Hz. You can then use this symbol in your source code to
79 # calculate timings. Do NOT tack on a 'UL' at the end, this will be done
80 # automatically to create a 32-bit value in your source code.
82 # This will be an integer division of F_USB below, as it is sourced by
83 # F_USB after it has run through any CPU prescalers. Note that this value
84 # does not *change* the processor frequency - it should merely be updated to
85 # reflect the processor speed set externally so that the code can use accurate
90 # Input clock frequency.
91 # This will define a symbol, F_USB, in all source code files equal to the
92 # input clock frequency (before any prescaling is performed) in Hz. This value may
93 # differ from F_CPU if prescaling is used on the latter, and is required as the
94 # raw input clock is fed directly to the PLL sections of the AVR for high speed
95 # clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
96 # at the end, this will be done automatically to create a 32-bit value in your
99 # If no clock division is performed on the input clock inside the AVR (via the
100 # CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
