摘　　要：本文介绍了TMS320F2812的eCAN模块与TMS320LF2407的CAN模块之间通信以及两者与广州致远的CAN-USBI智能接口卡之间通信时CAN控制器的硬件电路设计及应用方法。利用该方法可以在波特率高达1Mbps的条件下可靠、稳定地传输数据,而且时间延时很小。在双PWM变频调速系统中的应用结果表明了该方法的可行性。The hardware circuit design and application methods of the CAN controller were introduced when the eCAN model of TMS320F2812 communicated with the CAN model of TMS320LF2407 and the two models communicated with CAN-USB I intelligent interface card made by Guangzhou Zhiyuan.This method could make data transmission reliable,stable and give a small delay.The method was used in double PWM speed-adjusted system and proved to be feasible.
