摘要
CAN中继和网桥是大型CAN网络组网中的必要设备。CAN网桥可以实现CAN通信距离的延长和网络的扩展,以及不同网络之间不同通信速率的转换和路由选择。本文从软硬件两方面提出了一种4路CAN网桥的设计方案。该方案采用集成CAN控制器的ARM微控制器LPC2194作为主控芯片,具有隔离和保护的CTM8251T作为CAN收发器。
CAN relay and network bridge are the required equipments in large CAN networks.CAN bridge can extend the distance of CAN communication,broaden the network,and realize rate conversion and routing.The software and hardware design of four CAN bridge is proposed,using ARM chip LPC2194 with integrated CAN controller as main cantrol chip,and CTM8251T with isolation and protection as the transceiver.
