Part Number: IWR6843
Other Parts Discussed in Thread: MMWAVE-SDK, ,

i am using mmWave SDK 3.5 and industrial toolbox 4.5.1 ->lab->out of box->  "ods_point_cloud_68xx_hwa"  

above demo reference manual(on website ) tells that it is compatible with ES2.0 device only but unfortunately it  works with ES1.0 device but it is not working with ES2.0 device then why TI reference is misguides us 

Please provide "ods_point_cloud_68xx_hwa"  demo project which will works on IWR6843 ES2.0 devices

i read "Migrating to xWR68xx and xWR18xx Millimeter Wave Sensors" this document and changes as per document but still i am not getting LVDS output so please provide proper guidance and Demos for IWR6843 ES2.0 devices  

thanks in advance...

    Hello

    Can you please check the LVDS output feature with the ES2.0  iamges on the ES2.0 board that you have.

    For compatibility there are API calls for the basic RF front of the deice which differ between the two versions of the Silicon revision.

    Hope this helps you proceed with right image for the feature you are looking for.

    Thank you,

    Vaibhav

    Hello Roshan,

    The ODS point cloud demo provided in industrial toolbox 4.5.1 is compatible with and works only on ES2.0 devices as mentioned in the user guide. This is also confirmed by the version of MMWAVE-SDK used in the CCS projectspec for this demo which is 3.5.0.4. MMWAVE-SDK versions starting from 3.3.0.3 and above are compatible only with ES2.0 devices as noted in the SDK user guide and the migration guide you referred above.

    However, we do find that there is a discrepancy / old-information in the ODS point cloud demo user guide as shown below. This section need to be removed and we will update it in a future release.

    In the meantime, please follow this section from the 68xx AoP - mmWave SDK Demo instead. Select the device as xWR68xx_AOP and SDK as 3.5.0.4 and send configuration from the visualizer as noted.

    Regards

    -Nitin

    can you please tell me step by step how "ods_point_cloud_68xx_hwa"  (mmWave SDK 3.5 and industrial toolbox 4.5.1 ) demo run on ES2.0 devices 

    what are the changes required/mandatory  to run this project on IWR6843 ES2.0 device if you provide screen shot with info that would be great.

    As I noted before, the detailed step by step procedure, with snapshots, is given the 68xx - ODS point cloud demo user guide, with the minor discrepancy in the user guide noted above. Please follow the steps below.

    NOTE: This procedure has been verified on an ES2 ODS board, so if you're still not able to get it to work, check and re-check that you have followed the instructions down to the last detail. The lab does not require any change and works as provided.

    1. Follow this user guide up to the following step:

     2. Then select the following in the device and SDK drop downs:

    3. Next, Press SEND CONFIG TO DEVICE as shown below, you should see the messages shown in the console:

    4. Finally, click the PLOTS tab in the visualizer to visualizer the plots as shown:

    Here i attached picture of my custom IWR6843 ES2.0 board as per this antenna pattern what values need to change please suggest

    ANTDEF_AntGeometry gAntDef_IWR6843AOP = {
    .txAnt = {
    {0, 0},
    {2, 2},
    {0, 2}
    },
    .rxAnt = {
    {1, 1},
    {1, 0},
    {0, 1},
    {0, 0}
    }
    };

    The above structure and it’s mapping to the physical antenna design is defined in the SDK at the following location (aoa2dproc DPU documentation).

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\datapath\dpc\dpu\aoa2dproc\docs\doxygen\html\index.html

    You can check the following section and modify the antenna structure according to your physical antenna design.
