16×16点阵LED电子显示屏的设计
假设如果原本某个汉字的字型（第一个字型），其编码为：
00H,10H,20H,30H,40H,50H,60H,70H,80H,90H,0A0H,0B0H,0C0H,0D0H0E0H,0F0H； 第二个字型的编码为：
10H,20H,30H,40H,50H,60H,70H,80H,90H,0A0H,0B0H,0C0H,0D0H0E0H,0F0H, 00H,
也就是把第一个字型的编码中，第1行显示数据，变为第2行显示数据；第2行显示数据，变成第3行显示数据；第3行显示数据，变成第4行显示数据；第4行显示数据，变成第5行显示数据，以此类推。
5.3 汉子取模
一个国标汉字是由16X16即256个点（像素）来构成的，显示一个汉字该亮哪些点这些复杂的工作都交给取模软件来完成，同时，取模软件也负责把要显示的汉字转化成程序中要用到的显示代码，代码以一定的规律表征了该亮的点（一般用“1”表示）与不该亮的点（一般用“0”表示），一共256位。单片机负责将这些代码一段一段有规律地送到LED屏，比如第一次输出表示第1列的16位代码点亮第1列、紧接着再输出16位代码去点亮第2列……直到点亮第16列然后再重新点亮第1列……，如此循环，就完成了这个汉字的显示。单片机输出的速度足够快时，由于视觉暂留现象使得人眼在同一时刻感受到了这16列输出的信息，也就是看到了这个汉字。
