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。
Accompanying today’s highly developed information age, LED display control technology has also made great strides in the field of information. This paper introduces a dot matrix LED display system based on H8 / 3048 singlechip. Hardware includes PC, H8 / 3048 MCU and LED dot matrix display. The system uses a low-cost microcontroller system to achieve a fixed display of Chinese characters, horizontal movement, vertical movement and flashing display, the transmission process using XMODEM protocol to ensure the accuracy of data transmission. This paper introduces the design and implementation of the LED dot matrix display and software design, analyzes the driving mechanism of LED dot matrix display and the system frame of dot matrix display.
