摘　　要：为了实现在PC端监测CAN总线网络,需要将CAN帧转换为USB帧。设计了一款具有传输速率快、可热拔插、稳定等点的CAN总线开发工具,该工具以16位单片机MC9S12UF32为主控制器,该芯片集成了USB接口,选用CAN控制器MCP2515完成CAN通信功能。通过自主开发的PC上位机对该工具进行了测试,验证了该工具的可靠性。In order to achieve in PC monitoring CAN bus network, you need to CAN frame into USB frame. This paper design a CAN bus developing tool with high speed, hot-plug ability and stability,which uses 16-bit mierocontroller MC9S12UF3.This controller integrates USB interfacewithout CAN,so MCP2515 is selected as peripheral CAN controller to complete CAN communication. Test this tool through the PC host developed autonomously, verifying its reliability.
