用C语言编写一个程序，能用蜂鸣器实现一段青花瓷音乐的一段播放_蜂鸣器唱歌代码青花瓷

##青花瓷片段的乐谱如下

其实现代码如下：

#include <REGX52.H>
#include "Delay.h"     //引用了头文件，其代码在最后面
#include "Timer0.h"    //引用了头文件，其代码在最后面
 
//蜂鸣器端口定义
sbit Buzzer=P2^5;
 
//播放速度，值为四分音符的时长(ms)
#define SPEED	500
 
//音符与索引对应表，P：休止符，L：低音，M：中音，H：高音，下划线：升半音符号#
#define P	0
#define L1	1
#define L1_	2
#define L2	3
#define L2_	4
#define L3	5
#define L4	6
#define L4_	7
#define L5	8
#define L5_	9
#define L6	10
#define L6_	11
#define L7	12
#define M1	13
#define M1_	14
#define M2	15

#define H4_	31
#define H5	32
#define H5_	33
#define H6	34
#define H6_	35
#define H7	36
 
//索引与频率对照表
