- # WinAVR Sample makefile written by Eric B. Weddington, J�rg Wunsch, et al.
- # Modified (bringing often-changed options to the top) by Elliot Williams
- # make all = Make software and program
- # make clean = Clean out built project files.
- # make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).
- # make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
- # 4.07 or greater).
- # make program = Download the hex file to the device, using avrdude. Please
- # customize the avrdude settings below first!
- # make filename.s = Just compile filename.c into the assembler code only
- # To rebuild project do "make clean" then "make all".
- # Microcontroller Type
- # MCU = attiny13
- MCU = atxmega32a4u
- # AVRDUDE_MCU = atxmega32a4u
- # MCU = atmega8
- F_CPU = 32000000
- # Target file name (without extension).
- TARGET = adc
- # Programming hardware: type avrdude -c ?
- # to get a full listing.
- AVRDUDE_PROGRAMMER = avrispmkii # official name of
- AVRDUDE_PORT = usb # linux
- #AVRDUDE_PORT = lpt1 # windows
- ############# Don't need to change below here for most purposes (Elliot)
- # Optimization level, can be [0, 1, 2, 3, s]. 0 turns off optimization.
- # (Note: 3 is not always the best optimization level. See avr-libc FAQ.)
- OPT = s
- # Output format. (can be srec, ihex, binary)

- # List C source files here. (C dependencies are automatically generated.)

- # If there is more than one source file, append them above, or modify and
- # uncomment the following:
- #SRC += foo.c bar.c
- # You can also wrap lines by appending a backslash to the end of the line:
- #SRC += baz.c \
- #xyzzy.c
- # List Assembler source files here.
- # Make them always end in a capital .S. Files ending in a lowercase .s
- # will not be considered source files but generated files (assembler
- # output from the compiler), and will be deleted upon "make clean"!
- # Even though the DOS/Win* filesystem matches both .s and .S the same,
- # it will preserve the spelling of the filenames, and gcc itself does
- # care about how the name is spelled on its command-line.
