CCS/IWR6843: Overhead 3d People counting

user6095241

Part Number: IWR6843

Tool/software: Code Composer Studio

Hello

 

I am using iwr6843 ODS 2.0 development board, when running overhead_ 3d_ people_ Count application, the original version has no problem, but if I try to do some simple changes in RADARDEMO_detectionCFAR_priv.c, such as setting the threshold value to be a constant, the point cloud may not be visible after real-time display of MATLAB, and no error will be reported in the compilation, but a lot of warnings will be prompted as shown below.

What's more strange is that the same warning will still appear when the original version runs after decompressing the industrial toolbox and reloading the lab. (my industrial toolbox version is 4.3.2, SDK version is 3.3.0.03, CCS version is 9.3.0.00012, and the recommended version of 8.3.1 also has the same problem. Matlab version is 2019b and 2017a has the same problem.)

I'm looking forward to your reply.

Best regards.

    Hello user6095241,

     

    This looks to be a strange issue. Can you please provide me with more information on the changes you are making to the people counting lab and what you are trying to accomplish with those changes? I’m seeing that you have a lot of warnings, and while these do not necessarily stop the program from compiling and building, they could potentially cause problems when running the lab, as you have experienced. Consider trying your best to alleviate all of the warning messages.

    As noted in this thread (https://e2e.ti.com/support/sensors/f/1023/p/810054/2999270#2999270) the codesize warning can be ignored as it does not affect the performance of the program on IWR devices. Please refer to other preexisting E2E threads to fix the other warnings. If you need assistance with any warnings not found on E2E, let me know.

    Also, in regards to the warning messages remaining even though you are unzipping the original toolbox, please ensure that you are selecting “Rebuild Project” as opposed to simply “Build Project.” Rebuilding the project will clean and remove any lingering changes from the previous builds of the project and should ensure that your project will work correctly as detailed in the industrial toolbox.

     

    Regards,

    Thank you for your response, but it seems that the problem has not been solved. First of all, even if I choose to “rebuild” a project, the above problems still can't occur which is that the places you had changed would still warning even I have decompressed and reloaded the original edition again. What’s more, in the toolbox version of 4.3.2, the RADARDEMO_detectionCFAR_priv.c is put in “common” folder, It always warning that

    Invalid project path: Include path not found (D:\project\workspace_v9\overhead_3d_people_count_68xx_dss\common).overhead_3d_people_count_68xx_dss, And I don't know if it has any impact.

     

    Secondly, I mainly changed function RADARDEMO_detectionCFAR_raCAAll in RADARDEMO_detectionCFAR_priv.c, in order to observe the detected point cloud shape with lower antenna height, the other codes maintain the original version. In all distance segments, I directly add the assignment code below

    And in angle section, the same operation is used with different value

    RADARDEMO_detectionCFAR_priv.c

    You can replicate that process very easy, and I've uploaded my RADARDEMO_detectionCFAR_priv.c,

     

    At last, in RADARDEMO_detectionCFAR_priv, it seems that we can’t set the breakpoint.

     

    Best Regards.

    Hello user6095241,

     

    I was able to run the original overhead 3d people counting demo unaltered from the industrial toolbox and am seeing the same warning messages as you have detailed. This leads me to believe that this is normal and that these warnings should not be the cause of your issues. In regards to your issues with the point cloud not appearing within the MATLAB visualizer, I did not experience this. I recommend you to flash the debug binary onto your device and debug within CCS. You can look at the following document which details these steps:

    <mmwave_industrial_toolbox_4_3_2/labs/common/docs/software_setup/using_ccs_debug.html

    Running the debug within CCS will allow you to see any runtime errors which would stop the point cloud data from being displayed on the visualizer. Any error messages will appear on the console, which should make it easier to debug any issues. Please let me know if you need any other assistance and attach any screenshots of the debug screen so I can look in more detail.

     

    Regards,
