单片机控制系统和微机系统之间通信的几个技术问题

Several Techric problems about Communication between Embedded Micrccontroller and Microcomputer

单片机控制系统中,多CPU结构的采用大大增加了单元模块间通信的任务。为了解决调试模块通信方面的困难,作者提出使用微机系统分别与单片机系统的各模块通信后,再完成模块联调的方法,易于发现通信问题,调试过程也明朗清晰。本文详细论述了单片机控制系统和微机系统之间通信时存在的软硬件方面的关键技术问题。

In embedded microcontroller system, the adoption of multiprocessor greatly depends on the communication among unit modules. In order to solve the debugging difficulties, the writers propose to use PC to commumicate with each module re-spectivly and then accomplish the whole system debugging. It will be easier to find errors and will make the debugging process simpler and clearer. In this paper, the key technic problems of software and hardware about communication are expounded in detail.
