##############music的makefile文件################################

# Hey Emacs, this is a -*- makefile -*-

#

# WinAVR Sample makefile written by Eric B. Weddington, J鰎g Wunsch, et al.

# Released to the Public Domain

# Please read the make user manual!

#

# Additional material for this makefile was submitted by:

#  Tim Henigan

#  Peter Fleury

#  Reiner Patommel

#  Sander Pool

#  Frederik Rouleau

#  Markus Pfaff

#

# On command line:

#

# make all = Make software.

#

# make clean = Clean out built project files.

#

# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).

#

# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio

#             4.07 or greater).

#

# make program = Download the hex file to the device, using avrdude.  Please

#             customize the avrdude settings below first!

#

# make filename.s = Just compile filename.c into the assembler code only

#

# To rebuild project do "make clean" then "make all".

#

# MCU name

MCU = atmega8

# Output format. (can be srec, ihex, binary)

FORMAT = ihex

# Target file name (without extension).

TARGET = music

# List C source files here. (C dependencies are automatically generated.)

SRC = $(TARGET).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.

ASRC =

# Optimization level, can be [0, 1, 2, 3, s].

# 0 = turn off optimization. s = optimize for size.

# (Note: 3 is not always the best optimization level. See avr-libc FAQ.)

# Debugging format.

# Native formats for AVR-GCC's -g are stabs [default], or dwarf-2.

# AVR (extended) COFF requires stabs, plus an avr-objcopy run.

呵呵，不错啊!

hotpower · 发表于 2004-12-28 21:59:54

请大家注意:

1.makefile中的-ffreestanding

这样可以用

void main(void)

{

2.菜鸟的心得

MAKE FILE文件参数为：

MCU = atmega8

F_CPU = 8000000

听听吧，虹彩妹妹

xwyjianghu · 发表于 2006-9-18 18:06:45

不过现在不知道怎么把简谱转换成标准格式？

huangfan · 发表于 2006-10-27 18:41:55

music.c文件中

"#include <avr/ina90.h> "这句话编译的时候通不过.

请问，为什么?

huangfan · 发表于 2006-10-28 12:47:04

xwyjianghu的程序是好使的；

如果将楼主的上面那条语句除去，还是不好使。

请楼主帮忙回答！

shunpu · 发表于 2006-12-20 11:08:41

hotpower · 发表于 2006-12-22 20:04:24

这是用旧版本做的,新版本应该为:

//#include <avr/ina90.h>

#include <compat/ina90.h>

音乐程序！直接就可以下载到AVR内，就可以听到了吗？不用别的辅助硬件

我是新手！

请大家多多指点！

谢谢！

sundaqing 需要蜂鸣器及相关驱动，如果直接就能听到，那还不神了。

hotpower 菜农

可不可以把ICC的程序找一下。我到SL的网站查了没有看到。

Makes the compiler generate code that takes the given amount of cycles to perform, that is it inserts a time delay that lasts the specified number of cycles.

本不想多说的,只是看到这个帖子是"酷"贴,还是忍不住了.

这种放音乐的东西不实用,甚至是"害"人的.51也就算了,AVR这样做容易使学习者走到弯路上.

下载我的电子书第8章看看偶的放音乐例程,比较一下吧.
