LAUNCHXL-F280025C: 烧写TI官方例程有关CAN程序的例程的问题

Part Number: LAUNCHXL-F280025C
Other Parts Discussed in Thread: C2000WARE

TI工程师,你好!我烧写了路径为D:\ti\c2000\C2000Ware_MotorControl_SDK_3_01_00_00\c2000ware\driverlib\f28002x\examples\can中的例程,改为外部回环收发,如下图 使用CAN卡以及测试CANTX,CANRX均未获得CAN信号,求解释,谢谢。

  • 使用CAN卡以及测试CANTX,CANRX均未获得CAN信号



  • 1、四个例程均下载过;2、使用的是官方的LAUNCHXL-F280025C开发板;3、can卡为周立功USBCAN,连接J14上的CANH和CANL,其中S4开关向下。

  • can_ex2_loopback_interrupts 该例程就是使用的 外部回环

    This example sets up the CAN controller in External Loopback test mode.
    //! Data transmitted is visible on the CANTXA pin and is received internally
    //! back to the CAN Core. Please refer to details of the External Loopback
    //! Test Mode in the CAN Chapter in the Technical Reference Manual.
    //! \b External \b Connections \n
    //! - None.


    若是您想使用USBCAN传输的话,建议您参考 280049的 CAN例程 can_ex3_external_transmit
