16*16 LED显示屏控制系统的设计研究

Research on the Design of 16*16 LED Display Control System

基于串行通信的16*16 LED显示屏控制系统的设计,利用Visual Basic提供的MSComm控件建立PC机与单片机的串行通信,设计友好的操作界面,实现控制LED显示屏。上位机采用VB编程,通过按键向单片机输送控制信号,控制显示屏的循环次数、显示方式。单片机采用MCS-51单片机指令系统进行编程实现串口数据接收,并控制驱动16*16LED显示屏做出相应的显示。经测试该系统能实现良好的自动控制,功能满意。

The design of 16＊16 LED display control system makes use of the MSComm control widget provided by Visual Basic to establish the serial communication between PC and MCU,and to create friendly interface,in order to realize the control of the LED display.Serial procedures programmed by Visual Basic control the cycle and the mode of the LED display by pressing the key on the interface to send control signals to MCU.The MCS-51 code system is adopted to program to receive the serial data.The driver circuit is used for controlling and driving the dispaly of the LED display by the assembler codes.After being tested,the system can carry out automatic control satisfiably.
