摘要
提出一种通过对实时时钟电路的分时操作实现通信的双单片机系统的结构 ,给出了公共总线结构和通信协议 ,该方案可以扩展为多单片机系统。
A scheme about dual microcontroller system which communication realized by operating real time clock by turns was proposed.Its structure of bus and communication protocol were presented.This scheme may be used to multiple microcontroller system.
