51单片机音乐代码怎么写

求89C51单片机播放音乐的C语言代码！

#include#includesbitSPK=P2^7;unsignedcharfrq;unsignedintflag;voiddelayms(unsignedcharms);voidmain(){TMOD=0x01;frq =0x00;TH0=0x00;TL0=0xff;TR0=1;IE=0x82;flag=0;while(1){switch(flag){case0:frq++;break;//Flag 如果flag设置为0，则frq增加情况1。
:frq--;break;//flag 如果flag设置为1，则递减f rq}if(!(frq^0xff))flag=1;//如果frq递增为FFH，则flag设置为1并且frq正在增加准备减少。
if(!(frq^0x00))flag=0;//当frq减小时。
当达到 00H 时，标志设置为 0，并且 frq 准备增加延迟。
ms(15);}}Interrupt1using1 中的 voidtimer0(){TH0=0xfe;TL0=frq;SPK=~SPK;}voiddelayms(unsignedcharms ) //延迟 Subroutine{unsignedchari;while(ms--){for(i=0;i

用51单片机做音乐播放只能播放一句代码如下求大神解答！急急急！

请高手帮忙解读一下51单片机音乐代码
