基于C8051F040的CAN总线中继器设计与实现

Design and Implement of the CAN Bus Repeater Based on C8051F040

提出了一种双MCU的CAN总线中继器设计方法,并给出了以C8051F040处理器为核心的硬件实现方案。通过对中继器MCU0和MCU1的状态和控制设计,很好地解决了中继器的主从状态的转换,使系统具有结构简单、实时性高、可靠性高等优点。

A new design of the CAN Bus repeater based on double MCU is proposed in this paper. And the hardware implementation of using C8051F040 processor as the core is presented. Through the design of the status and control of repeater MCU0 and MCU1 the switch of the master-slave status of the repeater is well realized. The proposed system features simple structure, real-time function, and high reliability, etc.
