基于STM32单片机的无线LED消息显示系统

Wireless LED Display System Based on STM32 MCU

以STM32单片机为核心,根据实际使用要求对LED显示器内容进行设置,并支持多块LED显示器的任意组合与拼接,实现多种信息显示方式。数据信息通过PC机串口通信进行实时调整,由无线收发模块KYL1020U完成远距离传输,并显示在LED显示器上。系统将字模转换部分放在PC端,减轻了单片机端的处理任务,同时系统可以扩展更多的数据信息显示功能。系统结构简单,体积小,重量轻,使用方便,测试结果表明该系统具有实时性与高可靠性等特点,能够满足用户的实际需求。

Wireless LED display system is proposed. The system uses STM32 Micro Controller Unite（ MCU） as its core.The display content can be set according to actual requirement. The system supports manifold combination modes of multiple LED display,and achieves a variety of information display mode. Data information coan be real-time adjusted through PC serial port. Remote transmission of data is accomplished by wireless transceiver module KYL1020 U and then displays on LED. Text conversion is finished on PC in order to reduce the processing tasks of MCU. At the same time,the system can be extended to have more data information display functions. System has simple structure,small volume,light weight and convenient use. Test result shows that the system also has the real-time characteristics and high reliability,can meet users＇ actual requirements.
