20070721 WinAVR-GCCのMAKEファイルについて

ちょっと前にmakefileは、MFile を使用した例を書きましたが、ターゲットが同じであれば、
雛形としてつくってあるmakefileをコピーして、ちょこっと編集して使いまわせます。

一応以下のmakeファイルに赤文字を入れておきました。
実際のところ、最近書き換えるのは
TARGET = led
SRC = $(TARGET).c
この2行だけです。

# Hey Emacs, this is a -*- makefile -*- #---------------------------------------------------------------------------- # WinAVR Makefile Template written by Eric B. Weddington, J?rg 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 name MCU = atmega168 # 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 = 20000000 F_CPU = 20000000 # Output format. (can be srec, ihex, binary) FORMAT = ihex # Target file name (without extension).

(C dependencies are automatically generated.) SRC = $(TARGET).c # List C++ source files here. (C dependencies are automatically generated.) CPPSRC = # 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.
