这是大一时候做的小玩具，可以显示字符文字，可以滚动显示😀

演示视频：

预备：

一.进制转换

取模数组都为十六进制数0x ~~。
在进行进度转换时不能带进0x
十六进制转换为二进制时，位于首部的所有0不显示，而尾部要显示如：0x42—（0）1000010, 0x3e—（00）111110

二.流程

先确定哪一行亮。（亮的一行为0，不亮的为1）
在确定这一行那些亮。（亮的一列为1，不亮的为0）

例如让第二行亮，第二行中第2，7个亮

三.取模软件设置

软件：PCtoLCD2002

Aduino代码

int CLO = A3;   //定义时钟输出引脚。
int LA = A2;    //定义数据锁存引脚【一行数据传完，这个脚位由低变高，然后点阵显示数据】

int n=0;
int ys=100;
unsigned int H[8]={0x7f,0xbf,0xdf,0xef,0xf7,0xfb,0xfd,0xfe};     //行，地址。第几行准备点亮。

unsigned int zi[10][8]=
