因?yàn)槌绦蚴且徊揭徊綀?zhí)行，從主程序看，找執(zhí)行播放音樂函數(shù)，播放完音樂再去執(zhí)行流水燈的程序，這兩個(gè)程序是排著隊(duì)串行處理的，要想并行處理，可以試試將蜂鳴器發(fā)聲的相關(guān)程序放在定時(shí)器中斷函數(shù)中。中。

函數(shù)play_song（）包含while（1）語句。將“ 1”更改為適當(dāng)?shù)臈l件。

給你一個(gè)蜂鳴器音樂與流水燈同時(shí)實(shí)現(xiàn)功能的編程思路，不代表此程序能夠直接正常運(yùn)行。

play_song（）里有死循環(huán)while(1)，程序到這里打轉(zhuǎn)轉(zhuǎn)了。
