各位大佬，本人近期搞了一個旋轉LED顯示屏。寫好程序后進行運行。發現顯示的字是鏡像文字，比如說“老”，顯示的就是鏡像文字。然后我就想：即然是鏡像文字，那我就在取模軟件里取鏡像模，這樣顯示的就是正常字了。
結果實踐之后不得行，電機的正轉和反轉也對文字沒影響。跪求大佬指點一下怎么解決這個問題，采用16*16，程序如下，led低電平點亮
#include<reg52.h>
#define uchar unsigned char
#define uint unsigned int
uint num; //???????
sbit wai=P3^2; //??????
//???
void delay(uint z) //???
{
uchar x,y;
for(x=z;x>0;x--)
for(y=10;y>0;y--);
}
//?????
