摘　　要：为解决传统USB—CAN转换接口转换速率低的问题,基于STM32设计USB—CAN转换接口,STM32处理高速集成数据,设计USB—CAN转换接口连接方式,初始化USB—CAN转换接口寄存器,通过USB—CAN转换接口与上位机通信转换,完成基于STM32的USB—CAN转换接口设计。设计实例分析,结果表明,设计的USB—CAN转换接口转换速率明显高于对照组,能够解决传统USB—CAN转换接口转换速率低的问题。In order to solve the problem of low conversion rate of traditional USB-CAN converter,the USB-CAN converter is designed based on STM32.Based on STM32 processing high-speed integrated data,the USB-CAN conversion interface connection mode is designed,the USB-CAN conversion interface register is initialized,and the communication conversion between USB-CAN conversion interface and upper computer is completed through USB-CAN conversion interface.The results show that the conversion rate of the USBCAN converter is signifi cantly higher than that of the control group,which can solve the problem of low conversion rate of the traditional USB-CAN converter.
