信任您在作蜂鸣器发声试验时肯定为杂乱的频率与腔调之间的转化而伤脑筋，这儿向我们介绍一款东西可以大大简化转化操作，只需求输入简谱就能主动生成音乐播映程序代码。
以下此程序的主界面：
程序典范可以点主界面上的“关于”按钮后就能找到，可是代码也不全，需求参加对音乐程序的调用代码，其它典范里也写的很清楚了，只需求调用Play函数就行了，其调用格局如下：
Play(乐曲名,调号,升降八度,演奏速度);
经过实践，此函数的的后三个参数别离设为0,2和350时演奏出的音乐比较契合“原味”，下面给出本站的入门型51试验板结合此东西作的音乐程序：

曲谱存贮格局 unsigned char code MusicName{音高，音长，音高，音长…., 0,0}; 完毕:0,0 表明完毕(Important)
音高由三位数字组成：
个位是表明 1~7 这七个音符
十位是表明音符地点的音区:1-低声，2-中音，3-高音;
百位表明这个音符是否要升半音: 0-不升，1-升半音。
音长最多由三位数字组成：
个位表明音符的时值，其对应联系是：
|数值(n): |0 |1 |2 |3 | 4 | 5 | 6
|几分音符: |1 |2 |4 |8 |16 |32 |64 音符=2^n
十位表明音符的演奏作用(0-2): 0-一般，1-连音，2-顿音
百位是符点位: 0-无符点，1-有符点
调用演奏子程序的格局
Play(乐曲名,调号,升降八度,演奏速度);
|乐曲名 : 要播映的乐曲指针,完毕以(0,0)完毕;
|调号(0-11) : 是指乐曲升多少个半音演奏;
|升降八度(1-3) : 1:降八度, 2:不升不降, 3:升八度;
|演奏速度(1-12000): 值越大速度越快;

再例如：关于“世上只要妈妈好”的单片机音乐演奏程序
单片机演奏一个音符，是经过引脚，周期性的输出一个特定频率的方波。
这就需求单片机，在半个周期内输出低电平、别的半个周期输出高电平，循环往复。
半个周期的时刻是多长呢？众所周知，周期为频率的倒数，可以经过音符的频率计算出半周期。
演奏时，要依据音符频率的不同，把对应的、半个周期的守时时刻初始值，送入守时器，再由守时器准时输出凹凸电平。
下面是个网上广泛撒播的单片机音乐演奏程序，它可以循环的播映“世上只要妈妈好”这首乐曲。很多人都关怀怎么修正这个乐曲的内容，可是不知怎么下手。
做而论道对这个程序，给出阐明，期望对我们有所协助，今后我们自己就可以编写进去新的乐曲。
在这个程序中，有两个数据表，其间寄存了事前算好的、各种音符频率所对应的、半周期的守时时刻初始值。
有了这些数据，单片机就可以演奏从低声、中音、高音和超高音，四个八度共28个音符。
演奏乐曲时，就依据音符的不同数值，从半周期数据表中找到守时时刻初始值，送入守时器即可操控发音的腔调。
比方把表中的0xF2和0x42送到守时器，守时器依照这个初始值来发生中止，输出的方波，人们听起来，这便是低声1。
乐曲的数据，也要写个数据表，程序中以 code unsigned char sszymmh[] 命名。
这个表中每三个数字，阐明晰一个音符，它们别离代表：
第一个数字是音符的数值1234567之一，代表多来咪发…；
第二个数字是0123之一，代表低声、中音、高音、超高音；
第三个数字是时刻长度，以半拍为单位。
乐曲数据表的完毕是三个0。
程序如下：
#include
sbit speaker = P1^7;
unsigned char timer0h, timer0l, time;

//======================================
应网友要求，下面再具体写一下曲谱和数据的转化联系。
以李叔同大师的《送行》的前二末节来阐明转化的办法。
这部分的歌词是：“长 亭 外， 古 道 边，”；
这部分的曲谱是：| 5 35 1 － | 6 16 5 － |。
（留意：曲谱中的1是高音，上边是带点的；还有些音符，应该有下划线，在这儿都无法标出。感兴趣的网友应该去检查正规的曲谱。）
那么，据此就可以写出《送行》前二末节的数据表：
//————————————–
code unsigned char sszymmh[] = {
5, 2, 2, 3, 2, 1, 5, 2, 1, 1, 3, 4,
//嗦,中音,2个半拍; 咪,中音,1个半拍; 嗦,中音,1个半拍; 哆,高音,4个半拍
6, 2, 2, 1, 3, 1, 6, 2, 1, 5, 2, 4,
//啦,中音,2个半拍; 哆,高音,1个半拍; 啦,中音,1个半拍; 嗦,中音,4个半拍
0, 0, 0};
//完毕符号
//————————————–
记住：三个数字一组，代表一个音符。
第一个数字是1234567之一，代表音符哆来咪发…；
第二个数字是0123之一，代表低声、中音、高音、超高音；
第三个数字是半拍的个数，代表时刻长度。
当三个数字都是0，就代表乐曲数据表的完毕。
用这个数据表，替换掉程序中《世上只要妈妈好》的数据表，本程序就可以播映《送行》的前两末节。
