IWR6843AOPEVM: Inquiry about Adjusting Detection Frame Count on IWR6843AOPEVM

Part Number: IWR6843AOPEVM

Tool/software:

Dear TI Support Team,

I am currently working with the IWR6843AOPEVM and would like to inquire about adjusting the number of frames required for detecting a person.

Could you please advise if there is a method or configuration available to modify the frame count for human detection?

Thank you very much for your support.

Best regards,
Hidetaka

    Hi Hidetaka, 

    Sorry for the delayed response. Thanks for your patience. Can you let me know specifically which example software you are running? Is this regarding the 3D People Tracking example? Wall-mount or overhead? 

    Also, to get to the root of your question, are you noticing that people are not tracked quickly enough or you want to extend the range at which people can be tracked? In general I can point you to this tuning guide but I can provide more detailed guidance if there are specific issues you are facing. Please let me know.

    Best regards,

    Josh

    Dear Josh,

    Thank you very much for providing the reference materials. I will review them accordingly.

    Currently, I am using the 3D People Tracking sample software with the IWR6843AOPEVM, considering a wall-mounted setup.
    I would like to slow down the tracking speed of people and reduce the number of frames per second. Could you please let me know if there is a way to achieve this?

    In addition, I have noticed that the IWR6843AOPEVM becomes quite hot during operation. Could you advise whether this level of heating is considered normal or if it might be an issue?

    I appreciate your time and support, and I look forward to your guidance.

    Best regards,
    Hidetaka

    Dear Josh,


    The issue regarding the number of frames has been resolved, so I would greatly appreciate it if you could provide your feedback only on whether there are any concerns regarding heat generation.

    Best regards,

    Hi Hidetaka, 

    The high temperature of IWR6843AOPEVM is expected. The architecture of this device was not designed with low power consumption in mind so during operation power consumption can be very high even at modest frame rates.

    You can refer to the discussion in other threads on this forum. For example:  IWR6843AOPEVM: The temperature of evm is very high  

    In addition to the thermal design considerations from the linked post, there are also software techniques that you could employ to reduce the power consumption. These techniques are discussed in this application note: https://www.ti.com/lit/swra689

    Best regards,

    Josh
