基于SJA1000的CAN总线智能网桥设计

摘要

CAN ( Controller Area Network )总线越来越多的应用于工业及移动目标.SJA1000 作为一种独立的CAN总线通信控制器,可以实现 CAN 协议部分电路的结构和功能.本文主要内容是基于 SJA1000 设计一款CAN总线智能网桥,实现了不同的波特率甚至不同总线协议的 CAN总线间的信号转送.%CAN (Controller Area Network) bus is increasingly used in industry and mobile targets . As an independent CAN bus com-munication controller , SJA1000 can achieve the circuit structure and function of the CAN protocol part . The main content of this article is a CAN bus intelligent bridge design based on SJA1000 , which achieves signal transfer between CAN bus of a different baud rates or different bus protocols .
