3 # WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.
4 # >> Modified for use with the LUFA project. <<
6 # Released to the Public Domain
8 # Additional material for this makefile was written by:
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 board (see library "Board Types" documentation, NONE for projects not requiring
55 # LUFA board drivers). If USER is selected, put custom board drivers in a directory called
56 # "Board" inside the application directory.
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.
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
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
83 # If no clock division is performed on the input clock inside the AVR (via the
84 # CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.
88 # Starting byte address of the bootloader, as a byte address - computed via the formula
