IWR1443BOOST: SDK v.1.2.0 Capture Demo has been deprecated. Is there a new way to access raw data?

Part Number: IWR1443BOOST

Hi,

I'm just playing around with the new SDK, and I've noted that the Capture demo has been removed. Is there a replacement for this? As I had implemented my own algorithms on the raw data, which I would like to continue to use.

The Release Notes do say something about this.

Capture demo has been deprecated from the SDK and has been replaced by
multiple targeted products:

  • mmWave Studio that allows user to capture raw ADC samples from mmWave Sensors and thereby enable performance characterization and algorithm development for mmWave technology
  • mmW Demo (xWR16xx) within mmWave SDK showcases the instrumentation usecase where raw ADC samples can be collected from the device while mmWave sensor continues to process those samples within the device
  • CSI stream (IWR14xx) application within mmWave SDK that showcases how to stream ADC data over CSI-2 interface
  • "mem_capture" application within mmWave SDK that helps a user get started with our mmWave sensors and the SDK by showcasing how to configure the front end and EDMA data from ADCbuf to L3.

See doxygen of these new SDK modules for more internal implementation details.


I can't seem to find the relevant doxygen information (although I'll continue to search). But aside from the RECORD START function from the demo web gui, I don't see any way to save data (and particularly the directly captured ADC IQ data).

Thanks once again for any help

    Hello Khalid,

    Thank you for pointing this out. The main Doxygen is located in your ti folder at the following location: C:\ti\mmwave_sdk_01_02_00_05\packages\ti\demo\xwr14xx\mmw\docs\doxygen\html\index.html

    I will have to talk to our software team about the replacement for the Capture Demo.


    Cheers,

    I have located this, however I can't find any information on the points listed in the User Guide (capturing raw ADC data, CSI stream, mem_capture). Have I just missed something obvious?

    edit: I've had a bit more of a dig around and I think I've solved the issue. There are some new driver test files which I hadn't noticed before, and 'mem_capture' and 'csi_stream' are both in there. I guess it just wasn't very clearly documented, and as far as I can see it wasn't included in the main Doxygen. But from early testing 'mem_capture' seems to be working fine.

    Thanks that would be much appreciated if you could relay any information on this.

    Hi Khalid,

    Thanks for letting us know about the documentation, I will talk to the team about getting this updated.

    If you have any specific questions about mem_capture, csi_stream, or otherwise then feel free to open up a new thread!


    Cheers,
    Akash
