标题: 关于旋转LED显示屏的单片机程序问题
各位大佬，本人近期搞了一个旋转LED显示屏。写好程序后进行运行。发现显示的字是镜像文字，比如说“老”，显示的就是镜像文字。然后我就想：即然是镜像文字，那我就在取模软件里取镜像模，这样显示的就是正常字了。
结果实践之后不得行，电机的正转和反转也对文字没影响。跪求大佬指点一下怎么解决这个问题，采用16*16，程序如下，led低电平点亮

#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--);
}
//?????
uchar code shuzu2[]={

显示出现问题，肯定是你取数据错了，仔细检查显示程序的取字模的公式和提取字模的方式是否一致

取模：逐列式，逐行式，行列式，列行式，逆向，顺向都试一下。
