利用STC89C55RD+单片机实现无线LED点阵显示系统

Implementation of Wireless LED Display System by STC89C55RD+MCU

利用STC89C55RD+的在应用可编程功能和射频芯片nRF401,设计了一个无线数据通信方式下的LED点阵显示系统。该系统采用了上—下位机的结构构建,利用无线收发模块实现显示信息及控制命令的发送,并且充分利用了该单片机大容量的数据Flash区,通过在应用可编程功能实现多条信息的实时发布、擦除和修改。

A led display system based on wireless communication mode is designed by using the lAP function of STC89C55RD＋ and the RF chip nRF401.The system is built on the structure of the upper and lower machine.It sends the information and the control cammands by using wireless communication module.Take advantage of the large data flash and the lAP function of the MCU,the system can publish,erase or modify the information in real time.
