摘要
提出一种使用USB接口实现CAN总线网络与计算机连接的方案,可以应用在使用上位机监控CAN总线的场合。文中介绍了主控制器CY7C68013和CAN控制器SJA1000,讨论了CAN总线与USB之间的硬件接口电路。同时,分析了固件编程方法及主程序的架构。简要介绍了驱动程序开发。
This paper provides a scheme for CAN-USB bridge to communicate with the computer, which can observe the CAN network, introduces the CY7C68013 and the SJA1000 discusses the hardware and the firmware, the driver is also discussed. The system have implemented in the virtual vehicle test.
