摘要
介绍以VC++6.0MSComm控件为开发工具,使用自定义的通讯协议实现PC机与80C552单片机基于RS485总线的多机串口通讯系统的设计。给出了RS485串行通讯系统的硬件构成、下位机的程序流程图以及上位机通讯程序的部分源代码,并通过具体应用证明了本系统的可靠性。
The paper introduces a method for serial communication between PC and 80C552 single chip, taking Visual C ++ 6.0 MSComm control element as developing tool and a selfdefined protocol. This article also describes the hardware construction and software designing. Through the specific application, it proves that the system is reliability and stability.
