HI...I am trying to get output of the eval board into excel, so I can manipulate the data.  Currently unable to do it. Can someone help?  Thanks.

Currently, I think I am getting output in what appears to be hex format, with 2 hex characters separated by a space.  I don't know how to convert that into xls usable format

I want to be able to generate the frequency graph myself.

    Hello Raghu,

    How are you currently getting your data out? Are you using one of the demos?

    Regards,

    xwr16xx_processed_stream_2017_12_07T19_38_59_363.datHi Adrian, I am getting the data out by using the "Record Start" feature in the GUI.  The instructions are not clear how to get data out that can be read into xls, so I am just trying various things.

    The output I got is in Hex. See attachment.  

    Once I am able to get this in xls, I could get information such as range, velocity myself...I know the GUI provides that, but I wanted to be able to do it as well.

    Thanks,

    Raghu

    Hello Raghu,

    The output format of the data can be found in the doxygen, located at:

    file:///C:/ti/mmwave_sdk_01_01_00_02/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html

    Look for the section called "Output information sent to host". You are basically going to have a header followed by a series of TLV's. The format/size of all of these are described in the doxygen.

    Regards,

    Adrian

    Adrian, I had been made aware of the link you send by a Brad Griffis of TI, and did look at the section you indicated. Unfortunately, it didn't bring me any closer to getting the attached file into xls.

    Any step-by-step procedure to do that would be greatly appreciated.

    Thanks,
    Raghu

    Hello Raghu,

    Have you tried looking at the Javascript code? If you right click on the page source of the demo and select 'Inspect' this will open up the source code of the demo. From here you want to select Sources > App > Images > mmWave.js to find the Javascript source file for the demo.  The 'process1' function at line 1924 is where the data processing begins.

    The data is stored in a vector called 'bytevec'. Please take a look at how the TLV's are processed in the Javascript. This should give you an idea for how you can process the data yourself.

    Regards,

    Adrian
