IWR1642: Is it possible export Range-Azimuth heatmap realtime like OOB visualizer did?

Part Number: IWR1642

Hi team,

I got a questions form e2e China.

Customer is curious about how to export the Range-Azimuth heatmap realtime like OOB visualizer did through UART.

Do we have any demo or guide to do it? And how to do it?

Thanks for your help.

Regards,

Wesley

    Hi Wesley,

    The OOB demo already has the option to export Range-Azimuth heat-map related information using which the visualizer generates the heat-map. Can you please provide more information on what the customer is looking for as I'm not sure I understood your question.

    Regards

    Hi Nitin,

    Thanks for your reply.

    Sorry. I miss the important information.

    Customer is debuging the people counting demo, and he wants to export the range-azimuth heat map for tuning the parameter.

    So the question is: Customer is curious about how to export the Range-Azimuth heatmap realtime from people counting demo like OOB visualizer did through UART.

    If you have any further questions, please let me know. Thanks.

    Regards,

    Wesley

    Hi Wesley,

    I don't believe there is already a framework in place to export the heatmap. However, you may find this useful:
    After the for loop at line 976 in dss_data_path.c, the heatmap will be copied into memory - this is what the for loop does. If you lower the frame rate, you can send the data over UART here. You will probably have to make your own parser as well.

    Justin,
