51单片机蜂鸣器程序，音乐的随时跳转

这里修改：

sbit key1=P1^0

sbit key2=P1^1

void Play_Song(unsigned char i)

{

unsigned char Temp1,Temp2

unsigned int Addr

Count = 0 //中断计数器清0

Addr = i * 217

while(1)

{

if(key2==0)break     毁森      //插入这一句

Temp1 = SONG[Addr++]

if ( Temp1 == 0xFF ) //休止符

{

TR0 = 0

Delay_xMs(100)

}

else if ( Temp1 == 0x00 ) //歌曲结束符

{

return

}

else

{

Temp2 = SONG[Addr++]

while(1)

Delay_xMs(Temp1)

break

}

}

}

P12接J31的7脚，我在板子上已经激段测试过了，用的是89S52

花时间氏铅逗编的，希望你能采纳
