摘要
提出了一种基于通用串行总线的CAN总线通用接口模块设计方案,硬件结构主要由MSP430单片机、通用串行总线总线接口芯片CH375、CAN总线控制器SJA1000和CAN总线收发器82C250构成。在此基础上,设计了软件流程及PC机端应用程序。测试结果表明,CAN总线通用接口软硬件设计合理,工作可靠稳定。该接口与PC机连接方便,可应用于对CAN网络的实时监控与数据分析,具有体积小、即插即用等特点。
A scheme of CAN-Bus universal interface module base on universal serial Bus was proposed,the structure of hardware mainly consisted of MSP430,CH375,SJA1000 and 82C250.The software process and PC application program was designed.Tests results showed that the software and hardware of the CAN universal interface was reasonable,and the oporation was reliable.The interface was connected with the PC easily,could be applied to CAN real-time surveillance and data analysis,and had the advantages of small size,plug and play,etc.
