The purpose of this application note is to describe the main elements of an RS-422 and RS-485 system. This application note attempts to cover enough technical details so that the system designer will have considered all the important aspects in his data system design. Since both RS-422 and RS- 485 are data transmission systems that use balanced differential signals, it is appropriate to discuss both systems in the same application note. Throughout this application note the generic terms of RS-422 and RS-485 will be used to represent the EIA/TIA-422 and EIA/TIA-485 Standards.

用485实现单片机之间的串行通信。 从机部分一直等待主机的命令,接收到就发响应信号,然后接受数据,接受成功就用液晶显示

用485实现单片机之间的串行通信。 主机部分发送从机地址,等待从机响应,从机准备好就发数据,发完就接收从机的响应,接受成功就跳出循环,否则重发。
