Description: 介绍了一个以单片机DS80C320为控制器的点阵LED显示屏控制系统。该系统采用RS-232/RS-485通信标准，通过DS80C320的串行接口接收PC机的控制命令及显示数据，经处理后控制LED显示屏的扫描显示。该系统采用了一种新型的大容量闪速存储器29F040作为数据存储器。本文中给出了该控制系统的软硬件设计要点。-introduced a microcontroller DS80C320 controller for the lattice LED display control system. The system uses RS-232/RS-485 communications standards, DS80C320 through the serial interface of the PC to receive control commands and display the data, After treatment, control LED scanning revealed. The system uses a new type of large-capacity flash memory 29 F040 as a data memory. This paper has given the control system hardware and software design features.
