[整理]51单片机利用中断播放音乐程序中断播放音乐程序示例单片机机器周期的算法:比如一个12M的单片机，它的指令周期是1/12M，它的一个机器周期是12*1/12M,1/1M=1微秒在单片机中，它的中断源的定时记一个数是以机器周期为基准的，即对于一个12M的单片机来说，它的记数脉冲是1微秒，也就是说，记下两个数之间间隔的时间是1微秒。
单片机播放音乐其实也就是要干两件事情，能用单片机确定单调和节拍。
所谓音调，也就是音乐的频率，而节拍呢，就是间隔多少时间响一次，正好可以利用两个中断来完成这个工作。
怎么让一个单片机发出一个定频率的声音呢,比如一个440HZ的声音。
440HZ的声音的周期是T,1/440HZ,2272us 即控制给蜂鸣器输入端一个1136us的高电平，再给一个同时长的低电平，这样不断的交替进行，即可以得到440HZ的声音了。
那么这个过程如何用单片机的中断来实现呢, 关键就是该对中断TH0,TL0如何赋初值。
单片机的晶振是12M的，那么这个中断定时计一个数代表的时间是1us，即如果想要实现440HZ的声音，工作于方式1时，计数器最多可以记下65536的数，那么:TH0=(65536,1136)/256TL0=(65536,1136)%256在乐谱中，可以看到下图这样的数字和符号，其中1,C， 1,G表示曲调，与音频有很大的关系。
3/4表示乐谱中，以四分音符为节拍，每一小节有三拍，以下图为例说明:其中1，2为一拍，3，4，5为一拍，6为一拍，一共三拍。
1，2时长是四分音符的一半，即八分音符，3，4时长是八分音符，一半，即十六分音符，5时长是八分音符，6时长表示四分音符。
一拍的时长大约是400ms--500ms，以400ms为例，一拍是400ms,那么四分音符的时长就是400ms,那么八分音符的时长就是200ms，十六分音符的时长就是100ms，在单片机上，控制一个音符唱多长时间，可以用延时的方法，以十六分时长为最基本的延时单元，那么如果要延时八分时长，那么就运行两次这个延时单元，如果要延时四分音符的时长，那么就运行四次这个延时单元。

单片机蜂鸣器音乐代码
单片机蜂鸣器音乐代码在单片机的应用中，蜂鸣器是一个常用的音频输出设备。
它可以通过产生不同频率的声音来实现音乐播放、提醒和警报等功能。
本文将介绍如何使用单片机控制蜂鸣器播放音乐，并提供一个简单的音乐代码示例。
首先，让我们了解一下单片机蜂鸣器的工作原理。
蜂鸣器实际上是一个压电陶瓷元件，当电压作用于其上时，它会振动产生声音。
为了产生不同的音调，我们需要控制蜂鸣器的频率和占空比。
单片机通过IO口与蜂鸣器连接，并使用定时器来产生所需的频率。
具体的代码实现将依赖于使用的单片机型号和开发环境。
在这里，我们将以C语言为例，并基于51单片机进行说明。
以下是一个简单的单片机蜂鸣器音乐代码示例，演奏的是《欢乐颂》的前几个音符：```c#include <reg52.h>// 定义各个音符的频率#define C4 4778#define D4 4257#define E4 3792#define F4 3579#define G4 3189#define A4 2841#define B4 2531#define C5 2388// 延时函数void delay(unsigned int count){while(count--);}// 发声函数void beep(unsigned int frequency, unsigned int duration) {unsigned int i;unsigned long time;time = 11059200 / frequency; time >>= 1;for(i = 0; i < duration; i++) {P1 = 0x08;delay(time);P1 = 0x00;delay(time);}}// 主函数void main(){// 设置定时器TMOD = 0x01;TH0 = (65536 - 50000) / 256; TL0 = (65536 - 50000) % 256; TR0 = 1;// 播放音乐beep(C4, 100);beep(D4, 100);beep(E4, 100);beep(F4, 100);beep(G4, 100);beep(A4, 100);beep(B4, 100);beep(C5, 100);while(1);}```以上代码中，我们首先定义了各个音符的频率，这些频率是通过实验测量得到的，具体数值可能因蜂鸣器型号、电源电压等因素而略有差异。
