CCS/AWR1642: Radar Parameters

Ryan.Bishop
Expert 3900 points
Part Number: AWR1642
Other Parts Discussed in Thread: MMWAVE-SDK, MMWAVE-DFP

Tool/software: Code Composer Studio

Hello,

I am working with one of our customer as they begin designing with the AWR1642BOOST, TSW1400EVM, and mmWaveDevPack. They need assistance with the following questions so they can stay on track for development.

They have successful executed the Vital Signs Radar demo, but can you help with these roadblocks:

  1. In the “profile_2d_VitalSigns_20fps_Front.cfg” file there are a bunch a parameters. They need to understand better what they are and what ranges are allowed for each of them. Do we have any documentation for this?

  2. Other parameters for the radar operations are believed to be embedded into the C code, especially those related to the setting of the chirp. Where are these additional parameters and how can they be changed by the customer?

  3. They would like to save the raw radar data after it’s converted to base band, is there a simple way to do that with this board alone? As I mentioned above they also have the TSW1400EVM and the mmWaveDevPack board but if possible they'd like to avoid using them.

Thank you, let me know if you need any additional information.

    Hello Ryan,
    A1: Please refer to mmwave_sdk_user_guide.pdf that is available in MMWAVE-SDK . This details out each and every parameter in the configuration file and their valid ranges .

    A2: You can refer to the demo code that is available in the MMWAVE-SDK in "$mmwave_sdk_01_01_00_02\packages\ti\demo\xwr16xx\mmw" . The mmw demo also has detailed documentation in "$mmwave_sdk_01_01_00_02\packages\ti\demo\xwr16xx\mmw\docs\doxygen\html\index.html".

    A3: For capturing the data over LVDS using the TSW1400EVM , you can refer to the MMWAVE-DFP . The MMWAVE-DFP include the tool "Radar Studio" in "$mmwave-dfp\rf_eval\radarstudio\RunTime" that can be used to configure AWR1642BOOST , TSW1400EVM to capture the RAW ADC data.
    Please refer to the mmwave_dfp_user_guide.pdf in MMWAVE-DFP for the procedure to configure the AWR1642BOOST and capture using TSW1400EVM.

    Thanks,
    Raghu

    Hi Raghu,

    Thank you very much, the first two answers helped find more information on the parameters.

    For the customers third question, I believe they were curious if there's anyway to save the data WITHOUT using the TSW1400EVM. Are there any alternatives or is the TSW1400EVM a must-have when using the AWR1642BOOST?

    A fourth question: The customer thinks it would be helpful to have the makefile used to build the host part of the demo. That would be the qt based gui portion of the demo. It looks that that part is prebulilt and I could not see any file used to build it. Is that available?


    Regards,

    Ryan,

    Today, there is no alternative to using the TSW1400. We are working on releasing a new data capture card end of next month that would allow to stream data through Ethernet to a PC.

    Fourth Question
    We only offer limited support to modify the GUI. It is QT based which is open source. Customer could install QT and import the project provided.

    thank you

    Hi Cesar,

    Great, thanks for the update on the data capture card.

    For #4, I apologize for my ignorance since I'm not working with this EVM myself, could you point me towards the location of the file they can import into QT? I believe that's their question because they stated "I could not see any file used to build it. Is that available?"

    Thank you very much!

    Ryan,

    Please search the QT open source community. QT is not supported by our team.

    thank you
