基于STM32的CAN-USB转换模块

摘要

The paper proposed a design method of CAN-USB transformation module based on the STM32F105 microcontroller. It introduced the design plan of hardware and software. Combining the advantages of CAN bus and USB bus, the module has the characteristics of plug and play,baud rate setting online,CAN messages creating and so on. The practical results show that the transformation module can achieve the task of communication between the PC and CAN device well. It provides a new way of monitoring CAN device on the spot.%提出了一种基于STM32F105微控制器的CAN - USB转换模块设计方法,介绍了转换模块的软硬件设计思路.转换模块结合了CAN总线和USB总线的优点,具有即插即用、在线设置波特率、在线创建CAN帧消息等特点.实践证明:转换模块能够很好地实现PC机与CAN设备的通信任务,为监测现场CAN总线设备提供了一种新途径.
