C8051F040单片机CAN控制器的波特率设置研究

The research of the configuration of baud rate on C8051F040 CAN controller

结合CAN协议的有关规定,全面阐述了C8051F040单片机CAN控制器的波特率设置原理;并结合具体实例说明了C8051F040单片机CAN控制器的波特率设置寄存器B it Tim ing Register的设置步骤及原则.在此分析的基础上,成功地解决了船用航行数据记录仪采集单元与主机之间的CAN总线通讯,并且保证了传输通讯的稳定性.

This paper gives a comprehensive explanation of the configuration principle of the baud rate on C8051F040 CAN controller completely, and gives a concrete example to explain the Bit Timing Register configuration proocedure and principle of the C8051F040 CAN controller. On the foundation of this analysis, the CAN＇s bus communication is successfully implemented between collection cell of ship navigation data recorder and the main computer,ensuring the stability of transfer communication.
