The Multi-communication and Anti-interference Method of PC and SCMC
摘要/Abstract
摘要：
介绍了PC机与单片机的多机通信技术,给出了基于RS-485总线的PC机与单片机通信接口的硬件电路图及软件编程的代码;结合应用的实践经验,分析了影响RS-485通信的干扰源,阐述了硬件线路和软件设计两方面的抗干扰措施.
Abstract：
The multi-communication technology between PC and SCMC is introduced.The circuit diagram and procedure code of the communication interface based on RS-485 are given.Incorporating with practical experience,dist urbance sources which disturb RS-485 communication has been analyzed and the anti2interference method in two aspects of the hardware circuit and the software designing is set forth.
