CCS/IWR6843ISK: Output DPIF_PointCloudSideInfo when detectedObjects flag is 2

Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843,

Tool/software: Code Composer Studio

Dear sir or madam,

Currently, I am doing some survey about the 60Ghz mmwave sensors, such as TI IWR6843, and I got the source code of Demo Visualizer for xwr68xx sensors in mmwave_sdk_03_01_00_02. We want to change the source code to output both DPIF_PointCloudCartesian and DPIF_PointCloudSideInfo when detectedObjects flag is 2. Can we realize it by changing the following code in function MmwDemo_transmitProcessedOutput in main.c:

if ((pGuiMonSel->detectedObjects == 1) && (result->numObjOut > 0))

 to the follows:

if ((pGuiMonSel->detectedObjects == 1) || (pGuiMonSel->detectedObjects == 2) &&
(result->numObjOut > 0))

Since we currently do not get one IWR6843ISK EVM, we can not debug it by ourselves. Could you please told us that whether it is practicable? We will also try it in the future when we get the iwr6843ISK EVM.

Thanks a lot.

    Hello Genming,

    The mmWave SDK demo CLI (command line interface) commands are documented in the mmWave SDK user guide (section "3. 4. Configuration (.cfg) File Format"). Here are the possible values for the "detected objects" parameter in the guiMonitor API:

    <detected objects>
    1 - enable export of point cloud (x,y,z, doppler) and point cloud sideinfo (SNR, noiseval)
    2 - enable export of point cloud (x,y,z,doppler)
    0 - disable

    So, if you set the parameter to 1 (which is the default setting generated by the mmWave Demo Visualizer GUI) then you will get both the point cloud data (DPIF_PointCloudCartesian) and the point cloud side info (DPIF_PointCloudSideInfo). Therefore, there is no need to change the source code if that is your goal.

    Please mark as answered if you question is resolved or reply if more support is needed.

    Regards,
    John

    Hi, JohnH,

    Thanks for your reply, I will try it when we get the IWR6843 EVM.
