标题: 关于普中科技ES2.0开发板点阵动画显示的问题
用的普中科技的ES2.0的开发板，求如何用这个板子实现点阵的动画显示呢，有用这个板子的大神么，希望给个程序看看，普中的学习视频觉得不是多很好，所以用的普中的板子看的金沙滩的学习视频，在看到点阵动画显示的时候，自己一直做不出那种效果！

你是问对人了，我就用这块板子。看我的名字，呵呵。
点阵嘛，想动态，我现在只有我初学时的程序，不是很好，只能是完成了动态显示而已，给你看看，不要笑就好。
#include<reg51.h>

void main ()

unsigned char i,j,k;
LKZ=0xff;
XP74HC595(0x00);

while (1)
{
for (i=0;i<17;i++)
{
for (j=0;j<50;j++)
                     {
for (k=0;k<8;k++)
{
XP74HC595(XS[i][k]);
LKZ=TAB[k];
delay(5);
LKZ=0xff;
XP74HC595(0x00); //消隐
}
}
}
}
}
我初学时的办法是很笨的，叫“硬来”。即：将显示内容逐帧列出，一次一帧，就动态显示了。希望能抛砖引玉。
