应用RS-485的PC与单片机通信研究

Research of the Communication between PC and SCM Based on RS-485

目前在工业控制领域中,RS-485已成为一种重要的通信手段。结合实际介绍了PC与单片机间进行RS-485串行通信的一般原理及常用芯片选择,并对通信过程中可能出现的问题进行了讨论,最后给出了相应的解决方案。

Now in the industrial control area, RS-485 has become an important method of communication. With the experiments the principle of serial communication between PC and SCM basing on RS -485 and the choice of the chip is introdnced, then the problems in the process of the communication is discassed and the solutions is given.
