# Hey Emacs, this is a -*- makefile -*-#----------------------------------------------------------------------------# WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.## Released to the Public Domain## Additional material for this makefile was written by:# Peter Fleury# Tim Henigan# Colin O'Flynn# Reiner Patommel# Markus Pfaff# Sander Pool# Frederik Rouleau# Carlos Lamas##----------------------------------------------------------------------------# On command line:## make all = Make software.## make clean = Clean out built project files.## make coff = Convert ELF to AVR COFF.## make extcoff = Convert ELF to AVR Extended COFF.## make program = Download the hex file to the device, using avrdude.# Please customize the avrdude settings below first!## make debug = Start either simulavr or avarice as specified for debugging, # with avr-gdb or avr-insight as the front end for debugging.## make filename.s = Just compile filename.c into the assembler code only.## make filename.i = Create a preprocessed source file for use in submitting# bug reports to the GCC project.## To rebuild project do "make clean" then "make all".#----------------------------------------------------------------------------# MCU nameMCU = atmega324pa# Processor frequency.# This will define a symbol, F_CPU, in all source code files equal to the # processor frequency. You can then use this symbol in your source code to # calculate timings. Do NOT tack on a 'UL' at the end, this will be done# automatically to create a 32-bit value in your source code.# Typical values are:# F_CPU = 1000000# F_CPU = 1843200# F_CPU = 2000000# F_CPU = 3686400# F_CPU = 4000000# F_CPU = 7372800# F_CPU = 8000000# F_CPU = 11059200# F_CPU = 14745600# F_CPU = 16000000# F_CPU = 18432000# F_CPU = 20000000F_CPU = 8000000# Output format.
