單片機(jī)多首歌曲播放演示

沒有辦法，電路圖壓縮一份上來！

下面是源碼:

#include<reg52.h>
#define uchar        unsigned char   
#define uint    unsigned int
uint Fre;
sbit spk=P3^4;
sbit sw=P1^0;

void delay(uint mS)

uint code FreTab_Low[7]   = {262,294,330,349,392,440,494};            //低音頻率表
uint code FreTab_Mid[7]   = {523,578,659,698,784,880,988};            //中音頻率表
uint code FreTab_Hight[7] = {1046,1175,1318,1397,1568,1760,1976};        //高音頻率表
