IWR6843ISK-ODS: IWR6843ISK-ODS standalone with Pi

Part Number: IWR6843ISK-ODS

Hello,

I would like to receive limited data (like target number) from IWR6843ISK-ODS (standalone) by a Raspberry Pi 4B.

In this application, the GUI is not required. CP2105 bridge is used on the IWR6843ISK-ODS.

Is there any suggestion how to do it?  What kind of driver on Pi is needed and can we use the pyserial to receive data?

Kind regards,

Nanjun

    Hi Nanjun,

    There is a couple places you can start with this, and it depends a bit on what demo/lab/firmware you are using on the device. The mmWave SDK contains some very basic python parser scripts for the Out Of Box Demo, which can be found at <sdk_install_dir>/mmwave_sdk_03_05_00_04\packages\ti\demo\parser_scripts

    If you are using a more complex demo from the mmWave Industrial Toolbox, you may need to modify this script, as the TLV's may not exaclty match. You could also refer to the People Counting Visualizer (which is based in python) in the mmWave Industrial Toolbox, and just pull out the lower level parsing code which it uses. This should support the majority of demos contained in the Industrial Toolbox. This can be found at <install_dir>\mmwave_industrial_toolbox_4_11_0\labs\People_Counting\visualizer.

    Let me know if you have any further questions.

    Best Regards,
    Alec

    Hello Alec,

    thanks for your reply.

    We would like use the overhead_3d_people_counting project.

    After I ran then mentioned visualizer, The program stops there. It shows "b'Debug: Init Calibration Status = 0xffe\n'" in the last row.

    Attached are the screen shots. How can it be fixed?

    While the gui codes in C:\ti\mmwave_industrial_toolbox_4_11_0\labs\People_Counting\overhead_3d_people_counting\gui works as expected. It seems this code is wroten fully by Matlab?

    Kind regards,

    Nanjun
