2.  分辨率32*32=1024点 显示一个汉字

    1 byte = 8 bits 

    1 bit 对应1个 LED点阵

    1024/8 bits= 128 bytes

设计数据类型如下：

typedef struct // 汉字字模数据结构

{

    unsigned char Msk[128]; // 点阵码数据

}DWord_GB2312;

3.  初步显示测试

   驱 动 方式：   1/4   扫

    意思是32bits分为4次扫描完成

   32/4=8 Row

    32/4=8 列

最小控制模块为8*8=64点阵

于是整个屏幕被分为4*4 = 16个小单元
