IWR1642BOOST: IWR1642 People Counting Demo GUI customization Compile Source file missing

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

Hi,

I'm trying to customize the GUI for IWR1642 people counting demo.

So after I made changes in main_pplcount_viz.m, I want to recompile the source code into a new executable file.

I opened file named: "pplcount_gui.prj".

This is the window I got from trying to compile the source code from people counting demo into an executable in Matlab compiler

These three files PreviewController.p, Utility.p and Webcam.p are missing.

So I went ahead to remove the three missing files, it did successfully compile into a new runnable .exe, however the functionality is crippled.

The program would not allow me to connect to the COM ports in the new .exe as shown below:

When I press "Connect", it does not make the connection through COM ports as shown on the command prompt on the left.
However, the given pplcount_gui.exe works perfectly, so I wonder if it's because files are missing in the compilation.
Thanks,
Jiaqi

    Follow-up: After I installed the USB Webcam add-on, Matlab compiler compiles my source code now without any errors saying missing files. However, the functionality of the .exe is still crippled. It won't connect to the COM ports and gives the same error message when I press "connect"

    Hi Jiaqi,

    Please try with the Lab0015 GUI, as it can support IWR1642 and is up to date.

    Regards,

    Hi Justin, 

    Could you please help with the questions below related to IWR1642:

    When we put a small book in front of the EVM, it will stop counting people. Is this a tuning issue? If so, what would you recommend to help with this item?

    Also we noticed if someone was moving and holding a book, the mmWave sensor would detect the book as a separate person. Therefore it would detect two moving objects, when there is just one. What would you recommend to help solve this?

    Best, 

    Ashley

    Hi Ashley,

    mmWave will go through some objects. Some objects will block the signal.  If there are points in the point cloud with the book in front of the sensor, then it can still detect people, but the detection thresholds need to change.

    For the issue where the sensor detects the person and the book - the allocation thresholds are too low.  Please increase these as described in the People Counting Tuning guide.

    Regards,

    Justin
