IWR6843ISK-ODS: [ITB4.2.0 - 3D people counting] Python visualizer stops updating graph after a while.

Big Fields

Part Number: IWR6843ISK-ODS

Hi,

I am running 68xx_3D_people_counting lab in mmwave_industrial_toolbox_4_2_0 and checking the data from radar using Python visualizer.

After I run gui_main.py and send config file to device, the Python visualizer starts plotting the data from radar.

However, after a while, the plotting will stop and will not be updated anymore.

So far I investigated this issue in my side, I figured out:

- parseData function in gui_main.py is called repeatedly.

- despite the function call above, parseUartThread(QThread).run function is not executed.

Could you tell me why this occurs, and how to fix it?

Best regards,

Fields

Hi Fields,

I've asked an expert to look into this and we should have an answer for you sometime next week.

Hi Fields,

I am currently looking into this. Can you confirm that when this issue occurs, the gui still responds to mouse inputs?

Hi Fields,

I believe this is due to the serial api failing after some time. You can do the following:

Periodically check that there is data returned when the parser is called
1. Probably about once per second, does not need to be frequent
If there is no data, multiple frames in a row, then close the serial object, create and open a new one

Regards,

Justin
