IWR6843AOPEVM: Overhead project

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: IWR6843AOP

Tool/software:

Dear TI Experts,

    I have use TI solutions for 5 years. Now I have meet one puzzle question when transfer lab0020_pplcount_Overhead project to match newly IWR6843AOP ES2.0. I have followed swra656b.pdf(Migrating to xWR68xx and xWR18xx Millimeter Wave_Sensors) and changed the source code and projectspec files and modify the compile macro from ODS to AOP. Then finally after every changed I could think, The bin file has been flashed into IWR6843AOP ES2.0,  the senosr can work. The install environment matched user guide.   But when GUI_B_gui_filteringLogic.m used to show the running status, the people and the stance status not work well, because it detect many ghost target and wrong stance.    While the guide shows it works well with IWR6843ODS sensor without issues, and it also provided AOP, ODS project spec files.

    I have also try to modify the mmw_pplcount_demo_default.cfg file.  Changed the .cfg file

chirpCfg 1 1 0 0 0 0 0 2
chirpCfg 2 2 0 0 0 0 0 4

to

chirpCfg 1 1 0 0 0 0 0 4
chirpCfg 2 2 0 0 0 0 0 2.

But it also not worked well.     So how can I make it working well?   

BR

    Hi,

    Are you using the right antenna geometry? It is different between ODS and AOP. What is your configuration file?

    Best,

    Hello Nate, 

        Happy  to  receive  you reply!

        The .cfg file we used is mmw_pplcount_demo_default.cfg from the lab0020_pplcount_Overhead, like as below:

    sensorStop
    flushCfg
    dfeDataOutputMode 1
    channelCfg 15 7 0
    adcCfg 2 1
    profileCfg 0 60.6 200 7 40 0 0 82 1 128 5300 0 0 48
    chirpCfg 0 0 0 0 0 0 0 1
    chirpCfg 1 1 0 0 0 0 0 2
    chirpCfg 2 2 0 0 0 0 0 4
    frameCfg 0 2 64 0 100 1 0
    lowPower 0 0
    cfarCfg -1 0 0 8 4 4 0 6120
    cfarCfg -1 1 0 4 2 3 0 6120
    SceneryParam -1.18 2.12 1 2.0 -0.5 2
    GatingParam 3 2 2 2 12
    AllocationParam 50 120 0.01 5 1 20
    StateParam 5 5 10 20 5
    VariationParam 0.2887 0.2887 1 1
    MaxAcceleration 0.1 0.1 0.1
    AllocZone 0 1
    CloudPersistence 0
    SNRFilter 4 40
    trackingCfg 1 2 250 10 200 100 90
    sensorStart

    I have found no antenna geometry command in the cfg file, and no antenna geometry code files in the lab of lab0020_. .

    Hi Nate,

        Yes. I have already used the newly project for people counting. While I just used the old project cause it has matched stance detect matlab files can.  

        1. Maybe the old project can't use the flexible .cfg for antenna geometry for AOP?

        2. And the updated people counting project also can use the tb_3_6_2 stancne matlab files?  If so, Should I change something from the p.c. project?

    Regards,

    Chao

    I think this is likely. Please use the most up to date software that we provide.

    You can use the industrial visualizer instead of this MATLAB in the latest toolbox. See the user guide I sent in the previous post.

    reply: Could you provide the old ods cfg file or aop cfg file to my email or attac.  Or where can I modify the antenna geometry, then I will do it with hard coded.

    reply: In my memories, the industrial visualizer could not show the stance. Right?

    I just want to evaluate the stance possiblitiy with AOP ES2.0.

    Hi,

    Please send a link to the TB 3_6_2. I'm not aware of this package. Is this TI material?

    Best,

    Hi Nate,

        Yes. It's a TI material, industrial_toolbox_3_6_2, as an elder TI fan.  I think you can find it. hah.

    Hi,

    As far as I can tell (and please correct me if I'm wrong), this code is no longer publicly available online. We have had more than 10 toolbox updates since this version in the industrial toolbox (which has also been replaced by the radar toolbox, which has more than 10 updates since then too). Please either provide a link to this software online, or update to the latest version, or just a version that is publicly supported.

    Best,

    Nate

    Hi

    OK. I will check the link or use the latest version.

    Thank
