Avr2011 LED Demo Makefile
From HacDC Wiki
Cut and paste the following into a file called Makefile in the same directory as the LED_Demo.c
# WinAVR Sample makefile written by Eric B. Weddington, Jörg 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 program = Download the hex file to the device, using avrdude. Please # customize the avrdude settings below first! # Microcontroller Type #MCU = attiny13 # MCU = attiny2313 # MCU = atmega8 # MCU = attiny45 # MCU = atmega88 MCU = atmega88 # Target file name (without extension). TARGET = LED_Demo # Programming hardware: type avrdude -c ? # to get a full listing. # AVRDUDE_PROGRAMMER = dapa #AVRDUDE_PROGRAMMER = usbtiny # Note: have to use sudo make for USB # AVRDUDE_PROGRAMMER = dt006 AVRDUDE_PROGRAMMER = avr109 #AVRDUDE_PORT = /dev/usb # dummy, but it's fun :) #AVRDUDE_PORT = /dev/parport0 # linux # AVRDUDE_PORT = lpt1 # windows AVRDUDE_PORT = /dev/ttyUSB0 BAUD_RATE = 9600 ############# 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) FORMAT = ihex # List C source files here. (C dependencies are automatically generated.) SRC = $(TARGET).c # 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.
