单片机，原来也是音乐家：），如下图的案例，MCU也可以实现播放音乐曲谱哦！

其实用简单的电路+MCU + 蜂鸣器就可以play music了！

#include

sbit BEEP=P3^7;

unsigned char code SONG_TONE[]={212,212,190,212,159,169,212,212,190,212,142,159,212,212,

106,126,159,169,190,119,119,126,159,142,159,0};

unsigned char code SONG_LONG[]={9,3,12,12,12,24,9,3,12,12,12,24,9,3,12,12,12,12,12,9,3,12,12,12,24,0};

void DelayMS(unsigned int x){

unsigned char t;

while(x--) for(t=0;t<120;t++);

}

//播放函数

void PlayMusic(){

unsigned int i=0,j,k;

while(SONG_LONG!=0||SONG_TONE!=0){

for(j=0;j

BEEP=~BEEP;

//SONG_TONE延时表决定了每个音符的频率

for(k=0;k

}

DelayMS(10);

i++;

}

}

void main(){

BEEP=0;

while(1)

{

PlayMusic(); //播放生日快乐

DelayMS(1000); //播放完后暂停一段时间

}

}
