| 摘 要： | 介绍了一种基于无线数字传输芯片和单片机构成的LED大屏幕显示系统的设计，讨论了系统的硬件电路设计和软件设计。该系统分为两大块：发送模块和接收模块。在发送模块中，单片机先通过串口接收上位机发送的数据，再控制无线数字传输芯片把数据发出；在发送模块中，单片机会接收到与无线数字传输芯片地址匹配的无线数据，接着处理数据，然后发送到LED大屏幕进行显示。

| Abstract: | This paper introduces a wireless system completed with digital transmission chip and single chip microcomputer using for transmitting the data which LED large-screen should show.The hardware and software designs of the system are also discussed.This system is divided into two modules:sending module and receiving module. We use single chip microcomputer to receive data from PC through the serial port,then sending out the data through wireless digital transmission chip,in sending module.Single chip microcomputer will receive the wireless data when the address of wireless data is the same as the address of wireless digital transmission chip which we set up.The data will be sent to the LED large-screen after Single chip microcomputer deals with it. |
