STM32F103通用定时器PWM应用例程：蜂鸣器演奏乐曲

一．说明：本例程是将流明LM3SLib_Timer.pdf文档中的例程9及例程10（PWM应用：蜂鸣器演奏乐曲），移植到STM32F103上。

二．流明LM3SLib_Timer.pdf例程9及例程10的拷贝：

例程9． Timer PWM应用：蜂鸣器发声

如图1.1所示，为EasyARM1138开发板上的蜂鸣器驱动电路。蜂鸣器类型是交流蜂鸣器，也称无源蜂鸣器，需要输入一列方波才能鸣响，发声频率等于驱动方波的频率。

图1.1 蜂鸣器驱动电路

程序清单1.9是Timer模块16位PWM模式的一个应用，可以驱动交流蜂鸣器发声，运行后蜂鸣器以不同的频率叫两声。其中"buzzer.h"和"buzzer.c"是蜂鸣器的驱动程序，仅有3个驱动函数，用起来很简捷。

}

例程10．Timer PWM应用：蜂鸣器演奏乐曲

程序清单1.10是Timer模块16位PWM模式的一个应用，能驱动交流蜂鸣器演奏一首动听的乐曲《化蝶》（乐谱参见图1.2）。"music.h"和"music.c"是演奏乐曲的驱动程序。

图1.2 乐谱《化蝶》

简谱是大众化的音乐记谱方式，比较容易理解和掌握。我们可以把一首乐谱（score）看成是由若干个基本的音符（note）单元组成。一个音符由音名和时值组成。音名就是低音、中音、高音的1234567（唱作do re mi fa sol la si），其本质是音符的发声频率。在头文件"music.h"里，用L1～L7、M1～M7、H1～H7定义了低音、中音、高音所对应的发声频率。时值是音符的发声时间长短，有全音符、二分音符、四分音符⋯⋯等等。音符可以后缀一个“符点”，表示时值增加1/2，特殊地，二分音符加符点时用“－”代替圆点。参见表1.26的描述。

表1.26 常见简谱音符示例

音符	名称	相对时值
5―――	全音符	T
5－	二分音符	T/2
5	四分音符	T/4
5	八分音符	T/8
5	十六分音符	T/16
5――	符点二分音符	T/2+T/4
5．	符点四分音符	T/4+T/8
5．	符点八分音符	T/8+T/16

在头文件"music.h"里定义有一个音符结构体tNote，有两个数据成员：音名mName和时值mTime。在C文件"music.c"里定义有一个tNote型常量数表MyScore[ ]，用来保存实际乐谱转换成tNote格式的数据。有了上述一点点乐谱基础知识，我们就可以很方便地编辑这个数表了。比如音符“3”转换为“{M3, T/4}”，音符“3．”转换为“{M3, T/4+T/8}”，等等。在"music.c"里，已经在数表MyScore[ ]里给出了乐谱《化蝶》开头一部分音符转换结果，其余部分请感兴趣的读者补充完整。
