IWR1642BOOST: Device is not recognized by Windows 10

Steven Pajak

Part Number: IWR1642BOOST

Sometimes my IWR1642BOOST device fails to connect to Windows unless I unplug it and plug it back in, but sometimes it connects successfully. When it does not connect, the yellow DS4 LED does not light up, but when it does connect, it seems to work correctly. Is there something I'm missing to get this device to connect consistently?

Hi Steven,

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

Cheers,

Akash

Thank you for the quick response. I have a couple other questions/issues:

I'm running the People Counting lab with the People Counting Visualizer Matlab program. I have a USB webcam plugged in, but it doesn't show in the webcam drop down. When I try to run the software with the Integrated Webcam on my laptop, it crashes with the following error:

Struct contents reference from a non-struct array object.

Error in main_pplcount_viz (line 169)

MATLAB:structRefFromNonStruct

Is there a package I'm missing? I only Installed the Matlab v9.2 runtime (R2017a).

Also is there any information about how to retrieve data from this device to be used in my own custom software?

Thanks in advance for your help. Please let me know if you want me to move these to separate threads.

Hi Steven,

For the device connection issue, can you check your power supply to ensure it is 5V 3A? If not, please replace with the correct power supply.

In regards to the webcam, we have since removed the webcam support from the GUI because of compatibility issues.

If you want to parse the device output yourself, we explain the output structure at the bottom of the user's guide. From the data there it should be fairly straightforward to develop a parser.

Regards,

Justin

Justin,

Sorry for the late response. Thanks for the information, I believe that was indeed a power supply issue.

For the device output, do you have a user guide on how to retrieve the device output, or is it just a matter of using software to connect to both of the COM ports and listen to them? Is there a command I need to send to one of the COM ports to initialize the sensor?

Thanks again for your help.

Hi Steven,

For retrieving data, we have the output format explained in the lab user's guide. Basically, you must connect to the device, UART COM port at baud=115200 and DATA COM port at baud = 921600. Then send the configuration file on UART COM, and listen to DATA COM to receive data each frame.

Justin

What's the process for sending the configuration file on the UART COM port? Is there a certain format or way to encode the file to send all at once? I tried to send each line of the configuration file to the UART COM port separately but that doesn't seem to do anything. I used the example configuration files in the People Counting lab.

Hi Steven,

You should see output from the device after each command if you are connected with the correct baud rate. This should indicate successful or incorrect command.

I believe the original issue of the thread is resolved - please start a new thread for additional questions, I am going to close this one.

Regards,

Justin
