IWR1843BOOST: question about continuously streaming in mmwave studio

Part Number: IWR1843BOOST

I want to capture real time raw data by myself. I saw this post https://e2e.ti.com/support/sensors/f/1023/t/773502, there is a solution at bottom.

So I set "frame" to "0" in SensorConfig tab. And click "Trigger Frame"

The size of UDP data received is 393216, I think:

393216 = 2(I+Q) * 128(samples per chirp) * 128(chirps per frame) * 3(tx) * 4(rx)

And I assume it is time division modulated, so in each frame, chirps froms different tx have sequence like: tx0, tx1, tx2, tx0, ...

But I am not sure, and this size is not changed when I modify "Profile", which is very strange. So I hope someone can help me verify this. Thanks!

    HI, 

    Are you saying that you are using regular chirp configuration and program slope to be zero to capture CW data?

    After trigger capture, you should received a binary data file, is the file size correct?   Without your profile/chirp/frame configuration, I can not help you to check whether the size is correct?  Please send over your command history log.

    Hi zigang,

    This is the configuration I use, I set "No of frames" to 0 and use socket to receive UDP packet in real time. And each packet is a 393216 length array.

    And this size even won't change when I set "ADC Samples" from 256 to 128.

    When "No of frames" is not 0, I check the file size is correct.

    Thanks,

    HI, Yuan:

    It is not a regular mode that radar studio support.  We have never used in this mode and not sure what to expect. 

    The radar studio is communicate with DCA1000 using UDP packet.  There are some documentation on that part inside radar studio, 

    C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\ReferenceCode\DCA1000\Docs

    Hope you can get some help from this documentation.

    Best,

    Zigang

    Hi Zigang,

    Thanks for your answer. I check that file but not much related information. I will keep my assumption now because the processed result seems reasonable.

    Best,
