# Hey Emacs, this is a -*- makefile -*-#----------------------------------------------------------------------------# WinAVR Makefile Template written by Eric B. Weddington, J鰎g 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 = atmega16# 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.
