摘要
在分析嵌入式系统数据通信要求的基础上,研究并设计了一个基于CAN总线技术的通信子系统,用于嵌入式系统之间的数据通信,并给出了具体实现方案.该通信子系统由一片单片机芯片,一片双口RAM芯片和一片CAN控制芯片以及CAN接口芯片组成,其中单片机芯片和CAN控制芯片作为系统的控制部分,而双口RAM作为系统与主处理器之间的数据交换通道,从而使得分散嵌入式系统之间的通信变得更为方便简捷,并且该通信子系统具有一定的通用性和可剪裁性.
To communicate data in two or more embeded systems ,the comunication subsystem based on canbus technology is designed.In this subsystem, there are one mcu and one dual_port static RAM, one can_mcu and one can_interfacem,the can_mcu and mcu control the subsystem,the dual_port static RAM save data that communicate between the subsystem and embedded system, This subsystem has characteristics of genaral and it can be reduced or added easily in the embeded system, and the hardware structure is presented.
