摘要
介绍了在同一系统内 ,MCS51系列两单片机之间采用单向并行通信接口、主从双向并行通信接口、无主从双向并行通信接口实现双机互连的方法 ,分析了在每一种通信接口工作方式下数据传送的特点。这三种并行通信接口为单片机应用系统扩充硬件资源的设计提供了新的途径。
The realization approach of single direction parallel communication interface,principal and subordiˉnate parallel communication interface and arbitration parallel communication interface between MCS51serial sinˉgle chip computers in a system are introduced.Analyze the characteristic of every communication interface mode for transfering data.The three parallel communication interfaces may be applied to extend the hardware resource of an application system.
