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GB2312 80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 required 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 16-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 transferred to the LED controller to make a real display via Bluetooth. Started with a 16×64 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.
