多任務(wù)一般用RTOS的hwi、swi、task等進(jìn)行處理，如果僅是您貼的代碼中需加入屏幕顯示功能，您這里用的51，可以在播放音樂時插中斷刷新屏幕。

作者: George1 時間: 2018-2-24 12:32
謝謝指教,我想讓顯示和音樂播放同時進(jìn)行,寫頭文件模塊化,主函數(shù)中斷進(jìn)行兩個程序的執(zhí)行,可以嗎?怎樣寫
?

有p4嗎？

有P4, STC12 就有

明明是世上只有媽媽好的歌，什么生日歌？

作者: shuisheng 時間: 2019-1-23 20:26
12864的案例我空間案例很多，你可以參考一下。你上面的代碼不適合多首歌曲播放，最好的方式是將音符與節(jié)拍編輯好一起放到一個數(shù)組里，
例如0x11,0x04,
其中0x11中的0x1指的是中音，
(uint16 code FreTab_Low[7]={262,294,330,349,392,440,494};    //低音頻率表
uint16 code FreTab_Mid[7]={523,578,659,698,784,880,988}; //中音頻率表
uint16 code FreTab_Hight[7]={1046,1175,1318,1397,1568,1760,1976}; //高音頻率表)，
后一個1指向的是 523HZ，那就是說通過0x11能找到高中低音中的音符，0x04表示節(jié)拍(一種音符延時的長短),那么只要保證數(shù)組指針在++就能取出數(shù)組里的參數(shù)，一首歌一個數(shù)組就能擺平。

下面是具體一個例子:

#include<reg51.h>

#define uint8 unsigned char
#define uint16  unsigned int

sbit Music=P2^0;
sbit sw=P3^0;
void DelayMS(uint16 dly)
{
uint16 x,y;
for(x=dly;x>0;x--)
for(y=247;y>0;y--);
}

uint16 code FreTab_Low[7]={262,294,330,349,392,440,494}; //低音頻率表
uint16 code FreTab_Mid[7]={523,578,659,698,784,880,988}; //中音頻率表
uint16 code FreTab_Hight[7]={1046,1175,1318,1397,1568,1760,1976}; //高音頻率表

//大海啊故鄉(xiāng)
