51单片机4个74hc595驱动16x16点阵。程序加仿真成功。但是想改成8个74hc595，驱动32X32的点阵怎么改程序？
改了好久都改不对？求大哥大姐指导一下。
我的程序：
4个74hc595驱动16x16的。
#include<reg51.h>
#define uchar unsigned char
sbit si=P2^0; //74HC595串行数据段
sbit sck=P2^1; //74HC595移位时钟端
sbit rck=P2^2; //74HC595锁存端
uchar i,j,k,zb;
uchar xsz[32],xsz1[32] ;
uchar code smsg[8] ={0x80,0x40,0x20,0x10,0x08,0x04,0x02,0x01};
uchar code wz[][32]={
