单片机播放音乐的编程方法网络整理版
我将阐述播放音乐的软件编程方法。
原理：1’要让单片机控制扬声器发出音调只要计算出某一音频的频率，进而计算出周期，然后将这一周期除以二，即为半周期的时间。
利用定时器计数这半个周期。
每当计数到这个时间就将输出I/O口取反，重复这个步骤就可以得到这个音调的脉冲。
2’利用80C51扥内部定时器使用其工作在计数器模式MODE1下，改变计数值TH0,及TL0易产生不同频率的方法。
例如长生频率为532HZ的脉冲，其周期为T=1/523=1912us。
因此只要计数器计数956/1us=956。
在每次计数956次后将I/O口取反，就可得到中音DO（523HZ）。
计数脉冲值与频率的关系公式如下：N=Fi÷2÷Fr N:计算值Fi：内部计数时一次计数为1us，故其频率为1MHZ.3’其计数值的求法如下;T=65536-N=65536-Fi÷2÷Fr 其计数值的求法如下例如：设K=65536，F=1000000=Fi=1MHZ，求低音DO（261HZ），中音DO(523HZ),高音DO(1046HZ)的计算值。
T＝65536-N＝65536-Fi÷2÷Fr＝65536-1000000÷2÷Fr＝65536-500000/Fr。
低音DO的 T＝65536-500000/262＝63627中音DO的 T＝65536-500000/523＝64580高音DO的 T＝65536-500000/1047＝650594’ C调各音符频率与计数值T的对照表如下所示.在音乐中所谓音调其实就是我们所说的音高，在音乐中我们常把C 调上方的A作为标准音调，其频率等于440HZ。
当两个声音信号的频率相差一倍是也即f1=2f2,则称相差一个倍频程，在音乐中低音1和中音1，低和中2正好相差一个倍频程在音乐上称他们相差一个八度音，一个八音度有12个伴音,即为1-#1,#1-2,2-#2，#2-3,3-4,4-#4,#4-5,5-#5,#5-6,6-#6,#6-7,7-i.如果我们知道了这十二个基本音调的频率，我们就可以根据倍频程的关系得到其他调。

单片机音乐的编程我们知道，声音的频谱范围约在几十到几千赫兹，若能利用程序来控制单处机某个口线的高电平或低电平，则在该口线上就能产生一定频率的矩形波，接上喇叭就能发出一定频率的声音，若再利用延时程序控制“高”“低”电平的持续时间，就能改变输出频率，从而改变音调。
例如，要产生200HZ的音频信号，200HZ音频的变化周期为1/200秒，即5ms。
这样，当P2.5的高电平或低电平的持续时间为2.5ms时就能发出200HZ的音调。
乐曲中，每一音符对应着确定的频率，我们将每一音符的时间常数和其相应的节拍常数作为一组，按顺序将乐曲中的所有常数排列成一个表，然后由查表程序依次取出，产生音符并控制节奏，就可以实现演奏效果。
此外，结束符和体止符可以分别用代码00H和0XH来表示，若查表结果为00H，则表示曲子终了；若查表结果为FFH，则产生相应的停顿效果。
定时器T0工作在定时方式1，改变TH0及TL0，产生不同的音频频率。
必须考虑到中断响应时间的影响，尤其在高音部分，若忽略中断响应时间，会使音频频率比标准值低几十Hz，相当于1/4音程，很容易听出来，对低音部分影响不大。
一般中断响应时间为3～6个机器周期，经过反复试验取5个机器周期作为校正最为恰当，表1中所给的定时初值就是考虑中断响应后的定时常数。
另外，为避免T1中断可能引起杂音，应将定时器T0中断设为高优先级。
这样编写出来的程序播放的音与标准音叉进行差频校音，非常准确和谐。
本例中单片机晶振频率为6MHz。

频率表中的数据可以从表中查到，节拍时间表的数据是延迟时间的倍数；第二步，分别将两个表中的偏移地址送入两个指针寄存器；第三步，分别从两个表中取出频率值和音符的持续时间值，送入相应的寄存器中，供调用通用发声程序使用；第四步，调用通用发声程序发出音调。
我们知道，声音的频谱范围约在几十到几千赫兹，若能利用程序来控制单处机某个口线的高电平或低电平，则在该口线上就能产生一定频率的矩形波，接上喇叭就能发出一定频率的声音，若再利用延时程序控制“高”“低”电平的持续时间，就能改变输出频率，从而改变音调。
为了产生手弹的节奏感，在某些音符（例如两个相同音符）音插入一个时间单位的频率略有不同的音符。
