Arduino驱动LED显示屏出现问题

感谢ZZZ大侠的文章，让我将08接口的16*64 LED显示屏点亮了。原帖【Z】Arduino也能驱动LED显示屏，LED业界标准Arduino驱动方案解析@iceicon

但是没有让屏幕显示文字，只有线啊！！！！！
代码如下
int R1=7;
int STR=8;
int CLK=9;
int EN=2;


int dig0=3;
int dig2=4;
int dig4=5;
int dig8=6;
//int i,m;

unsigned char jj,j;


void setup()
{
pinMode(R1,OUTPUT);
pinMode(STR,OUTPUT);
pinMode(CLK,OUTPUT);
pinMode(EN,OUTPUT);
pinMode(dig0,OUTPUT);
pinMode(dig2,OUTPUT);
pinMode(dig4,OUTPUT);
pinMode(dig8,OUTPUT);
}

unsigned char zi[]={
