IWR6843ISK: IWR6843ISK Parameter Tuning

user6356280
Intellectual 315 points
Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVE-SDK

The following guide states that the parameters can be changed by mmWave-SDK.

・Detection Layer Parameter Tuning Guide for the 3D People Tracking Demo

・Group Tracker Parameter Tuning Guide for the 3D People Tracking Demo

The following guide states that the data can be viewed with the mmWave Demo Visualizer.

・MMWAVE SDK User Guide

However, the parameters described in the two tuning guides above (e.g., numAdcSamples and digOutSampleRate) are not found in the mmWave Demo Visualizer.

What do I need to do to change the parameters described in the two tuning guides above?

    Hello,

    The way the mmWave Demo visualizer works is that it creates a configuration based on your scene settings, then sends it to the device which initiates sensor startup. What you are able to do is set the scene parameters as desired, then click the button to save config to PC. Within the file there is "profileCfg" which has numAdcSamples and digOutSampleRate. Change them as needed, save it, then in the "Plots" tab of the visualizer you can click load cfg from pc and send.

    Hello,

    Thank you for your answer.

    I found profileCfg in the following file in mmWave SDK.

    I have checked the contents and it appears that there are multiple files with the same parameters.

    Which file should I change the parameters in to reflect them in the plot?

    mmwave_sdk_03_06_00_00-LTS/packages/ti/demo/xwr68xx/mmw/profiles

    Hello,

    Every cfg file has different parameters, but every single one of those will run on the 6843ISK. I would start with profile_3d.cfg as it is the most "basic" configuration that also includes elevation angle data for the pointcloud. If you want to know what a configuration's performance is like, you can input the first few parameters into the Sensing Estimator to get details such as maximum range and range resolution.
