    Hi Kalaiventhan,

    The starterware which is in VisionSDK components provides a demo application for CAN. Please refer ti_components\drivers\starterware_0x_0x_00_xx\examples\dcc_app

    There is no usecase which demonstrate reception & transmission of CAN messages in VisionSDK. Having said that, it's fairly simple to implement one. You could refer the I2C as an example and implement similar API's.

    HI sujith,


    thanks sujith.

    2) in the ti_components\drivers\starterware_0x_0x_00_xx\examples\dcan how to receive external data from the other device,i was trying to send the data into the TI BOARD using busmaster it shows some error message. so where we have to change the code for receiving data

    please give the suggestion as soon as possible

    regards

    Hi Kalai,

    This demo code is no longer supported. You might have to debug and make this module functional.

    The function System_dcanInitCfgStruct () defines the basic dcan configuration, probably, you should look at this and attempt to bring up CAN transmission first.

    Hi Kalai,

    The demo application transmit CAN message periodically and receives the same.
    You might want to update this, instead of periodically transmitting CAN message, transmit only when you have to. Please refer \vision_sdk\examples\tda2xx\src\modules\dcan\utils_dcan.c and function Utils_dcanPrdCalloutFcn (), Utils_dcanTxTsk ()

    I would suggest to add a option in menu to transmit know message on press of key, say "t". i.e. When you press "t" on console call function Utils_dcanPrdCalloutFcn (), ensure to disable the periodic call back in function Utils_dcanCreatePrdObj ().

    Try and understand how the messages are constructed, modify the same to suite your needs.

    Regards,
    Sujith
