IWR6843ISK: Regarding SDK to detect Interference and avoid it

Murakami Youhei

Part Number: IWR6843ISK

Hello,

We checked the video to detect the interference regarding the sensing and avoidance.

<training.ti.com/mmwave-awr1x-interference-detection-crucial-step-effective-mitigation>

Do you support mmwave SDK and the GUI to confirm this function?

Regards,

Youhei

    Hi, 

    I would recommend that you take a look at the "Interference Mitigation and Detection Lab" located in the mmWave Platform Toolbox that can be found on TI Resource Explorer, as I believe it will provide more detail into what you are trying to accomplish. Please let me know if you have any further questions.

    Best Regards,
    Alec

    Hello Alec,

    Thank you so much for your reply quickly.
    I could found  "Interference Mitigation and Detection Lab".

    I have some questions.

    (1) I understood that only xWR16xx or xWR18xx support this function as default.

    (1)- a: Is there a function to automatically stop the sensor(=same as sensorStop) when interference is detected?
    (1)- b: Can we operate this function with iWR6843ISK?
    Could you please let us know where to change the source code if it is possible?

    (2) Is it easy to add this feature to the CLI-based "mmwave_platform_1_2_1" that captures the ADC data using the DCA1000?

    For example, is it possible to create an "Interference Mitigation and Detection Lab" and "mmwave_platform_1_2_1" from "mmwave_sdk_03_05_00_04"?

    If it is yes, could you please how to change.

    We are using "C: \ ti \ mmwave_platform_1_2_1 \ tools \ studio_cli \ src \ pre-built-Binaries"
    It is desirable to be able to build and use the feature instead of original mmwave_Studio_cli_xwr68xx.bin.

    Thanks and Regards,
    Youhei

    Hi,

    Before diving into this demo, it may also be good to look at the problem from a high level. The following threads have some resources linked that discuss this topic in depth
    https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/907655/iwr6843isk-ods-iwr6843-ods-interference

    In regards to porting this demo to a 68xx device

    There are mainly two aspects to the interference demo:

    1. Rangeproc DPU and DPC of the SDK data processing chain was modified to include interference. The modified versions are packaged with the lab, and are available in victim/xwr1xxx/datapath.
    2. The rest of the lab is just the OOB demo with minimal changes (just enough to send the extra interference config).

     

    Since the SDK has support to compile the rangeproc DPU for 68xx, there won’t be too much effort to port point 1 above for 68xx.

     

    The SDK also has a OOB demo for 68xx; it should be possible to find out the delta between my program and the 16xx/18xx OOB demo in the SDK and telegraph that to the 68xx demo.

    Best Regards,
    Alec
