摘　　要：CAN总线是一种有效支持分布式控制和实时控制的、多主的异步串行通信网络。文章以C8051F060单片机内集成的CAN控制器为例,详细介绍了波特率设置的方法,分析了波特率设置的误差来源,并给出了波特率误差的消除方法。CAN bus is a kind of network with asynchronous and serial communication which caneffectively support distributed control and real-time control and multi-master. Taking integrated CAN controller in C8051F060 single-chip microcomputer as example, the paper introduced the setting method ofbaud rate in details. It analyzed error sources of baud rate setting and gave several ways for eliminating the error of baud rate.
