IWR6843ISK-ODS: Which verison of MMWAVE-SDK can support IWR6843ISK-ODS?

IWR6843ISK-ODS: Point Cloud Demo Threshold and Group Peaks Options

Hi Team,

mmWave Demo Visualizer seems not compatible with IWR6843ISK-ODS. I could not make sense of the plots it produced unless I am running 1RX, 1TX.
For ODS Point Cloud Demo lab25 I would like to have more options I can play with, suchlike disable group peaks from the same object, change CFAR, Doppler threshold and use different config files.

I am trying to detect the texture of surface. 

So the question would be

1 Is there a way to make mmWave Demo Visualizer works with IWR6843ISK-ODS?

2 How to modify lab 25 so I can have more tuning options.

    Hi Tianyu,

    1. The ODS point cloud demo is based on an old SDK so the output data format is not compatible with the latest mmWave Demo Visualizer which is why we have provided a custom Visualizer.

    2. While you don't have the tuning options in the GUI, you can change parameters like peak grouping and CFAR thresholds by modifying the corresponding commands in the profile config provided with the demo. For example, to disable peak grouping, you can modify the following command in the profile config and re-load the config (real-time tuning is not supported for the reasons given in item 1 above).

    peakGrouping -1 1 1 1 1 255 (peak grouping enabled in both range and Doppler domains)

    peakGrouping -1 1 0 0 1 255 (peak grouping disabled in both range and Doppler domains)

    You can similarly change the CFAR thresholds.

    Please refer to MMWAVE-SDK 2.1.0.4 user guide for details on the various configuration commands. Note that while the ODS demo is compiled with SDK 3.1.0.2 to add support for IWR6843, the code and hence the CLI commands, CFAR calculation etc are based on SDK 2.1.0.4.
