IWR1642: Format of Low Speed Data for IWR1642/IWR1443?

Raymond Mack

Part Number: IWR1642

I have searched the entire SDK for the data format of the low speed data output of the IWR1642 Boost demo. Oddly, "grep -r "low speed data" ." does *not* show that string which appears at least 4 times in the PDF User Guide. Guessing there are format characters in between that foil grep finding it there.

I am looking for information on the format of the data that comes out of the demo programs on the CAN bus for the target information.

I will search the actual code files in the meantime, but I am guessing it could take many hours to find data that ought to be in the User Guide.

    Hi Raymond,

    The SDK Out of Box demo sends a list of detected objects/points output over UART, where each point in the list contains co-ordinate information (X,Y,Z), intensity and velocity. The low speed data mentioned in the SDK user guide refers to the list of detected objects/points.

    Please note that the SDK OOB demo does not send any output on the CAN bus. The format of the output structure is defined in the HTML documentation available in the demo folders and this has been discussed in many threads on this forum. For example, you can look at the following thread to find out where to look for the SDK demo output data format: https://e2e.ti.com/support/sensor/mmwave_sensors/f/1023/p/660937/2428277#2428277

    Nitin:

    Thanks for the pointer. That should get me going for now. I'll go puzzle through those places and collect the interface design. Sometimes having the right search terms helps find things here. My searches did not turn up that thread.

    These threads are a great resource once you know where to look! Also, you folks that have the magic of where to go look are a great resource as well. Thanks for all you do!
