摘要
伴随当今高度发展的信息时代,LED显示屏控制技术在信息领域也取得了长足的进步。该文介绍了一种基于H8/3048单片机的点阵LED显示系统。硬件主要包括PC机、H8/3048单片机和LED点阵显示屏。系统利用低成本的单片机系统实现了汉字的固定显示、水平移动、垂直移动和闪烁显示,传输过程采用XMODEM协议来保证数据传递的正确性。该文介绍了LED点阵屏显示的机制和软件的设计实现,分析了LED点阵显示屏驱动机制,以及点阵显示的系统框架。
With the rapid development of information in our society,control technology of LED screen makes a great progress in the information field.This paper introduces a kind of matrix LED display system based on H8/3048 series MCU.The system can be divided into three parts: computer,single-chip micro-computer H8/3048F and LED display screen.The system can display the Chinese and characters in different forms,such as static,parallel shift,vertical shift and blinking display.The computer sends data in the form of data packet to H8/3048 series MCU according to XMODEM protocol so that the accuracy of data transmission is assured and implemented easily.The principle of LED screen and the design of software are introduced in the paper.The frame of system is established based on the principle.
