基于单片机的LED汉字条屏显示技术

摘要

The design of 16×16 LED Chinese characters display controller by means of dynamic scanning is produced.This article analyzed the theory of display Chinese characters simply.It research the matrix signals control of LED screen,information transmission and driving.This system uses the data input and series data output to phase.The results show this can reduce the assistant process of CPU and increase the send speed.%文中设计了一种基于单片机动态扫描控制的16×16LED汉字显示条屏,简单分析了汉字显示的原理,并对LED显示模块单元如何进行行列信号控制及信号传输中的驱动问题进行了研究。结果表明采用并行数据输入、串行数据输出的专用电路可大大减少CPU的辅助时间,提高数据的发送速度。
