在远程监控和工业自动化系统中,串口通信因其具有连接简单、使用方便、可靠性高的优点,得到越来越广泛的应用.讨论了采用WinCE嵌入式与MSP430单片机构建串口多机通信系统的问题,在分析了WinCE操作系统与MSP430单片机串口模块特性的基础上,给出了进行串口通信的总体框图,针对实际串口通信存在的问题制定串行通信协议,然后在该系统硬件基础上根据需要定制WinCE系统内核,最后实现串口通信设计.实验结果表明:该系统能够达到多串口通信的要求.%In remote monitor and industrial automation system, serial communication has been widely used because of its advantadges, such as easy connect, convenient to use, and high reliability. This paper discussed the problem of serial multi-machine communication system which equiped with WinCE embedded and MSP430 MCU. On the basic analysis of the WinCE operating system and characteristics of MSP430 MCU serial communications module, this paper presented whole block diagram of serial communication, and serial communication protocol had been formulated according to the present problems of serial communication. Then the customized hardware of the system was achieved based on the WinCE kernel. Finally it realized the design of serial communication. The experiement results show that this system can attain the requirement of serail communication.
