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。
