关于单片机蜂鸣器唱歌的问题，怎样让音乐播放一次后停下来

我是菜鸟，这是我的蜂鸣器唱歌程序，但是它每次播放一次后，又重新循环播放。我想让它在播放一次后就停止播放。怎么弄？求高手指点。

参考这个例子：
#include <reg52.h>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int

uchar i=0;
sbit SPK = P3^4;
sbit K1 = P1^0;
uchar code HI_LIST[]=
{
0,266,229,232,233,236,238,240,241,242,244,245,246,247,248
};
uchar code LO_LIST[]=
{
0,4,13,10,20,3,8,6,2,23,5,26,1,4,3
};

void T0_INT() interrupt 1
{
TL0 = LO_LIST[i];
TH0 = HI_LIST[i];
SPK = !SPK;
}

void DelayMS(uint ms)
{
uchar t;
while(ms--)
{
for(t=0;t<120;t++);
}
}

void main()
{
IE = 0x82;
TMOD = 0x00;
while(1)
{
while(K1==1);
while(K1==0);
for(i=1;i<15;i++)
{
TR0 = 1;
DelayMS(500);
TR0 = 0;
DelayMS(50);
}
}
}

include <reg52.h> #define uchar unsigned char #define uint unsigned int sbit BEEP = P1^2; uchar STH0, STL0; uchar time; uint code SONG_TONE[] ={64580,64684,64777,64580,64580,64684,64777,64580,64777,64820, 64898,64777,64820,64898,64898,64968,64898,64820,64777,64580, 64898,64968,64898,64820,64777,64580,64684,64260,64580,64684, 64260,64580,0} ; uint code SONG_LONG[] ={2,2,2,2,2,2,2,2,2,2, 4,2,2,4,1,1,1,1,2,2, 1,1,1,1,2,2,2,2,4,2, 2,4,0}; void delay(uint x) { uint i,j; for(i=0;i<x;i++) for(j=0;j<440;j++) ; TR0=0; } void main(void) { unsigned char i; TMOD=0x01; ET0=1; EA=1; for(i=0;SONG_LONG[i]!=0;i++) { STH0=SONG_TONE[i]/256; STL0=SONG_TONE[i]%256; TR0=1; time=SONG_LONG[i]*800; delay(time); } } void t0(void) interrupt 1 using 0{ TH0=STH0; TL0=STL0; BEEP=!BEEP;

你看一下音乐存放的数组song的话 会发现song数组中存放的规律是 频率，音长，频率，音长…… 所以第一个temp1 = song[addr++]; 读出的是频率 接着temp2 = song[addr++];读出的是音长，音长即1拍、1/2拍、1/4拍等

main函数最后加一句： void main(void) { unsigned char i; TMOD=0x01; ET0=1; EA=1; for(i=0;SONG_LONG[i]!=0;i++) { STH0=SONG_TONE[i]/256; STL0=SONG_TONE[i]%256; TR0=1; time=SONG_LONG[i]*800; delay(time); } while（1）; }
