基于单片机的LED显示屏控制系统
he LED Screen system based on the single-chip microcomputer
本文介绍了一种由单片机控制的16*64的点阵显示屏系统,开头论述了该系统实现的原理，并对该系统的硬件电路进行了分块说明。本系统采用上位机—核心控制单元—显示点阵3级模式，其中上位机将输入文字转换成字模数据，并通过串口通讯传送数据给核心控制单元；核心控制单元在接收到数据后，将数据存储到E2PROM中，并根据显示方式来实现对数据的调度；显示点阵从核心控制单元获得数据并完成数据的动态显示，核心控制单元是架设在上位机和显示模块之间的一座桥梁。最后本文论述了该系统针对单片机的抗干扰部分做的处理，用来提高系统的稳定性和可靠性。
he paper introduces a kind of 16*64 matrix LED display system based on enhanced 51 series MCU.It describes the principles of the system and the hardware circuit in blocks at the beginning of this paper. The system uses a mode in PC software-the control unit–dot-matrix display。The PC software translates characters into matrix data. After receiving the data by using the USART,the control unit stores the data into E2PROM before sending the data to dot-matrix display.The dot-matrix display gets the data and then finishes its dynamic display.So the the control unit is a communication bridge between PC software and dot-matrix display.Finally,this paper describes the work the system has done for the anti-jamming processing to improve the system stability and reliability.
