WinAVR(GCC)新手入门的makefile范例

WinAVR(GCC)新手入门的makefile范例

整理/测试：阿莫(armok) ,HJJourAVR / 2005-08-28 / www.OurAVR.com

#这是一个简单makefile,仅用于初学者使用
#修改于WINAVR20050214所生成的makefile
#简单实验只需更改 [ 单片机 类型][目标文件名][C源文件名][系统时钟频率]即可
#修改好参数后另存到 单片机 程序所在目录，然后执行[make all]命令
#生成 烧录FLASH的*.hex,烧录EEPROM的*.eep,调试用的*.elf 文件
#
#           www.OurAVR.com

# MCU name
# 单片机 类型 参考格式是：atmega8 / at90s2313 / attiny15
MCU = atmega16

# Processor Frequency.
# 系统时钟频率(Hz),用于生成延时 _delay_us() _delay_ms() 见delay.h
# 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.
F_CPU = 1000000

# Target file name (without extension).
# 目标文件名(即生成的.hex/.eep/.elf的文件名)
TARGET = main

# List C source files here. (C dependencies are automatically generated.)
# C源文件名（不带路径）
# 多个文件名间用空格隔开 例如 SRC = file1.c file2.c file3.c
# 不需要加上 h头文件
SRC = $(TARGET).c

#**************后面内容基本不需要修改，除非你是老手*****************************#

# Output format. (can be srec, ihex, binary)
# 输出烧录文件格式
FORMAT = ihex

# Optimization level, can be [0, 1, 2, 3, s].
# 优化级别
# 0 = turn off optimization. s = optimize for size.
# (Note: 3 is not always the best optimization level. See avr-libc FAQ.)
OPT = s

# Debugging format.
# 输出调试格式
# Native formats for AVR-GCC's -g are dwarf-2 [default] or stabs.
# AVR Studio 4.10 requires dwarf-2.
# AVR [Extended] COFF format requires stabs, plus an avr-objcopy run.
DEBUG = dwarf-2

# List Assembler source files here.
# 汇编源文件名（不带路径，但扩展名 .sS 需大写，否则将会被make clean 所误删）
# 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.

# 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
#
#----------------------------------------------------------------------------
# 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".
