以一下一個網(wǎng)上看到的幻彩LED驅(qū)動程序，我在51開發(fā)板上編譯通過了，可是
燈圈一直亮，按K1，K2都沒反應(yīng)，求幫助！
單片機源程序如下:
- #include<reg52.h>
- #include<intrins.h> //寫入頭文件
- #define uchar unsigned char
- sbit Send_Dat=P3^7; //數(shù)據(jù)輸出，接IN腳
- sbit key3=P2^1;
- sbit key2=P2^4;
- sbit key1=P2^7;
- uchar show[720]; // 8*3*10
- uchar xdata color[10][3]={
- 0xff,0x01,0x00, //0
- 0xff,0x01,0x00,
- 0xff,0x01,0x00,
