摘要
介绍了一种基于SPI(同步串行传输规范)的双机通信模块设计方法。该模块采用了两片PICF877A单片机,实现了双机主从串行通信的功能。同时简要阐述了该系统的设计思路,并给出了具体的实现方法。
This article introduces a kind of data communication module design of double SCM based on SPI.This model is made up of two PICF877A.It realizes the communication between the two SCM by SPI bus.The design idea and the method of realization are also presented in the article.
