TMS320F28379D: SFRA GUI connect PC

Part Number: TMS320F28379D
Other Parts Discussed in Thread: SFRA

Hi,support

When I used SFRA_GUI to connect with the computer, I found that the connection could not be established. The SCI communication was configured and the SFRA communication files were included in the project. What should I check for this situation? Please help me!

Thanks and regards,

Eric

    Hi Eric,

    First, please make sure the correct program is loaded on the device and running. Also, you may want to double check on the COM number from your device manager as this number may change.

    Another possible source is the SCI switch on F28379D controlCARD. The position 2 on A:SW1 is ISO UART communication enable. Please make sure this switch is at on position to ensure SCI connection between FTDI chip to C2000.

    Hi Han,

    Thank you for your patience.I have checked it according to your suggestion. After testing, SCI can send and receive by itself, So I think there is no problem with SCI communication,when I put the position 2 on A:SW1 at ON position, SFRA _GUI still doesn't connect  F28379D controlCARD.I want to know whether SFRA_GUI_config function is enough if only considering communication between SFRA _GUI and F28379D controlCARD. 

    In addition,from A:SW1 to FTDI chip, there should be no change on F28379D controlCARD, right?

    Thanks and regards,

    Eric

    Eric,

    On top of SFRA_F32_config and SRFA_GUI_config, you will also need to run the SFRA_F32_runBackgroundTask and SFRA_GUI_runSerialHostComms periodically in your background task to communicate with the SFRA GUI.

    For more details on how to integrate SFRA into your end application, please refer to the user's guide below. Thanks.
