of accountability, redress of orderse of the single chip microcomputer to send and receive signals are TTI level, drive and anti-interference ability is limited, practical cooperation with other bus realize in Internet, RS-485 bus is one of them. RS-485 bus is a balanced differential transmission, anti-jamming of the good and as far as 4000 m could be transmitted, interconnected as many as 128 single chip microcomputer, very comfortable a composition computer communication system.
In computer communication, the most important is to ensure that communications in an orderly way, and therefore need to strict communication protocol and perfect communication software, this paper will focus on introduces applied in a large project single-chip computer communication association Put the communication software design method.
This paper introduces a microcontroller itself provide the serial communication mouth, use custom serial communication protocol, plus the bus drives as MAX481, MAX483, MAX485, MAX487 combined into simple RS-485 communication network, finish between the single chip computer communication.
Keywords: SCM; Serial communication; RS-485 bus: computer communication agreement
