考虑传统的有线或无线控制的 LED 点阵显示屏需要在 Windows 计算机中进行操作控制，软件操作复杂，更新内容不及时，应用范围受限，为此提出一种基于 Android 控制的点阵显示屏控制策略。通过自建字库，可显示 GB231280规定中16×16分辨率的所有汉字和非汉字符号，在智能手机中运行 APP 软件编辑显示内容，通过蓝牙通信方式传送到点阵显示屏控制器可即时显示，实现显示内容即时更新。以一个16×64的基本显示单元入手详细阐述软件编程思路，照此可扩展到任意显示分辨率尺寸，最后给出一个32×64的显示实例。
Considering that traditional wired or wireless controlled LED dot matrix display screen is re-quired for operational control on a Windows computer,the software operations are complex,delayed update and limited by the range of applications,this paper proposes a control strategy for dot matrix display screen based on Android control.Through building font,all 1 6-bit resolution Chinese character and non-Chinese character symbols based on GB2312 80 can be displayed,then the display context can be edited by using the APP software running on smart phone,updated instantly when being trans-ferred to the LED controller to make a real display via Bluetooth.Started with a 1 6×64 basic display unit,this paper elaborates the software programming methods, it can extends to other isplay resolution size accordingly.Finally,a 32×64 display example is given.
