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 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".
59 #----------------------------------------------------------------------------
66 # Targeted chip architecture (see library "Architectures" 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 should be the frequency the system core runs at, after the system clock
83 # has been set up correctly and started.
87 # USB controller master clock frequency.
88 # This will define a symbol, F_USB, in all source code files equal to the
89 # input clock frequency of the USB controller's clock generator in Hz.
91 # For the XMEGA chips, this should be equal to a multiple of 6MHz for Low
92 # Speed USB mode, or a multiple of 48MHz for Full Speed USB mode.
96 # Output format. (can be srec, ihex, binary)
100 # Target file name (without extension).
104 # Object files directory
105 # To put object files in current directory, use a dot (.), do NOT make
106 # this an empty or blank macro!
110 # Path to the LUFA library
114 # LUFA library compile-time options and predefined tokens

134 # Make them always end in a capital .S. Files ending in a lowercase .s
135 # will not be considered source files but generated files (assembler
136 # output from the compiler), and will be deleted upon "make clean"!
137 # Even though the DOS/Win* filesystem matches both .s and .S the same,
138 # it will preserve the spelling of the filenames, and gcc itself does
139 # care about how the name is spelled on its command-line.
