Part Number: AWR1642BOOST
Other Parts Discussed in Thread: MMWAVE-SDK, MMWAVE-STUDIO, AWR1642

Hello,

What is the best method for collecting object data (output of radar processing) for the AWR16? Any help would be greatly appreciated.

    Hello Cristian,

    Please see the mmw demo application in the MMWAVE-SDK . Using the demo application you can configure the AWR1642 device to give out object data over COM port and you can visualize the data in the MMWAVE-DEMO-VISUALIZER (MMWAVE-STUDIO) .
    The documentation about the demo application can be found in "docs" folder of the respective demo application. This will help you understand the data and control path of demo application.

    Let us know if this is helpful.

    Thanks,

    Raghu,

    Thanks for the response. In trying to use the demo I was able to visualize the data; however, when I tried to record data for a period of time, the resulting .dat file is not usable. I open it in MATLAB, for example, yet the file has only random symbols and no actual data. How do I go about fixing this?

    Regards,

    Hello again Christian,

    Within the SDK there is an m-file, capture_demo.m, that provides an example of offline analysis with the dat file.

    The file can be found in the directory mmwave_sdk_<ver>\packages\ti\demo\xwr14xx\capture\ gui\capture_demo.m

    If you are going to run the capture_demo.m file please make sure the parameter values such as samples, # of chirps, etc are in alignment with the values you used from the capture script. Also, for the m-file to work make sure your .dat file is located or added to your MATLAB path.

    If you have not tried running this m-file yet please try it and let me know if this helps.


    Cheers,

    Akash, 

    I'm getting the following error when trying to run this capture_demo.m script. We made sure all the parameter values are set up correctly. 

    Any  ideas on what the problem could be? Also, the .dat file that is produced from the mmWave record feature looks like a whole lot of nothing. Any help is appreciated.

    Hi Jeff,

    I'm sorry but I don't have enough information to answer your question. As stated in my previous post, it looks like the source of your error is that the parameter values are not aligned appropriately. Your Matlab script isn't running properly which is why the resulting .dat doesn't contain any useful information. If you provide more information about the parameters about the parameters you are passing or possible changes you've made to the script then we can probably find the source of your problem.


    Cheers,
