摘要
RS485总线通信广泛应用于通信距离在千米以内的通信工程中。文章详细介绍了RS485总线的工作原理及串行通信方式,且为便于进一步深入理解RS485总线的应用,提出基于Proteus的RS485总线串行通信的设计与仿真,并以数码管显示为例,给出了其硬件电路的设计以及软件思路设计,最后利用Proteus软件对其进行了仿真。
RS485 bus communication is widely used in communication engineering with communication distance within a thousand meters.This paper introduces the working principle of RS485 bus and serial communication,and for further understanding of the RS485 bus,the design and Simulation of RS485 bus serial communication based on Proteus,and the Digital tube display system as an example,presents the design of its hardware and software design,finally has carried on the simulation using the Proteus software.
