Part Number: IWR1443BOOST

Hi,

Please teach me how to read the data file of mmWave Demo Visializer.

I use mmWave Demo Visializer,Online.
<dev.ti.com/.../>

Plots Tab,when I push "Recoard Start ",visializer made a data file.
(xwr14xx_processed_stream_.....dat )

But I cann't read this file as text .
It was not good to change encode variously.

Where is the special tool for reading this binary file?

Regards,

    Hi,

    The data format is same as the data transmit from UART from mmWave Demo.

    To process the recorded data: See the Visualizer User's Guide, section 4.4, to understand what the data contains. Information on the actual data is available in the doxygen - <mmWave_SDK_Install_DIR>\packages\ti\demo\xwr16xx\mmw\docs\doxygen\html\index.html.
    User's Guide: www.ti.com/.../swru529a.pdf

    There is a demo in beta that saves the recorded data to a human readable CSV file - you can read the code and understand the data conversion process:
    mmWave visualizer with the LOG function: dev.ti.com/.../

    The data saved in this file is the exact same data and format that is transmitted out of the mmWave device over the DATA_port. Users should see the mmWave demo doxygen in the mmWave SDK package to understand the format of the data and how to parse it.

    Hi,

    Thank you very much.

    Is there the beta version of "ti-widget-streamsaver" which can be accessed from the user's guide
    <www.dev.ti.com/.../index.html Widget-streamsaver>?

    I can not access it because I caught up with company security, but are there offline tools?
    We can access <https://www.dev.ti.com/>, so select "GUI" from here
    and go to <https://www.dev.ti.com/gc> , a choices and input boxes come up.
    What should I do next from here?

    If this is the case,
    should I analyze the data format and have to build my own tool ,
    in C or python?

    Hi,

    Is that possible access to ti-gallery? You can search "mmWave visualizer with the LOG" in ti-gallery. Link:

    Also, you can download the offline version through ti-gallery.

    Thanks.

    Hi,

    Thank you very match,but the installer GUI is not correct.

    I can not scroll the GUI at "I Agree".

    I can not change the size of this screen.

    I changed my Windows10(64bit)  settings and display resolution, I can not  be able to see the part of the radio button.

    Please change your resolution setting of your PC and try again.

    If it doesn't work, please try another PC. Thanks.

    Hi,

    Thank you.

    It was not possible to display the radio button by changing the resolution
    in Windows or adjusting the hardware.
    However, when I repeatedly click the arrow key and the mouse click several times
    in the lower part of the screen, I was able to transition to the next screen by chance.
    I happened to solve this problem.
