IWR6843AOPEVM: People Counting 3D demo

IWR6843AOPEVM: People Counting 3D demo configuration

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: IWR6843ISK

Hello,

I have been trying to port 3d people counting lab to SDK 3.2.06.AOP to use it with my IWR6843AOPEVM (ES1) device. I have read the answer posted in the related post (https://e2e.ti.com/support/sensors/f/1023/t/858170) and re-compiled the bin successfully after following the migration guide document as suggested.

To re-compile the bin I have removed the PLATFORMES2 symbol and adjusted SHMEM_ALLOC parameter. This way I could successfully rebuild the project without errors and flash it on to the device (Although I'm not sure whether this was the right way to do it).

My problem is that when I run the visualizer application, it connects successfully however I'm not receiving any frames after I send the config. I suspect that the issue might be caused by my configuration file. I tried both ODS and ISK sample configurations and also a custom one (that I built based on the demo profile inside the SDK) to no avail.

I have also tried calling the readAndParseUART function in the Python parser directly. It again connects to the device but I'm not receiving any data e.g. numPoints is always 0.  

Do you have any suggestions on how I can fix this? I'm not sure whether the problem is how I compiled the lab or the configuration file but if possible I'd appreciate a sample file that I can try.

Thanks a lot,

Eymen Gunay

    Hi Eymen,

    You should not change the SHMEM_ALLOC parameter. After you recompile, please run in debug mode, and see if the device is crashing. Check to ensure that the device receives and acknowledges all of the cli commands, and that sensor start is successful. 

    If the antenna geometry is wrong in the configuration, you will still typically get detected points, they just won't make any sense.

    Regards,

    Justin

    Thank you Justin,

    I have followed your suggestions and kept the SHMEM_ALLOC param and ran the program in debug mode. This way I could get a couple frames but nevertheless it froze right after.

    It was getting a little too time consuming for me to try porting and debugging it so in the end I have simply ordered an IWR6843ISK ES2.0 and I'm testing it successfully with this one. 

    Thank you again for taking your time to answer me.

    Have a good day,

    E.
