Original question:

AWR1642BOOST: FMCW to CW mode

AWR1642BOOST: AWR1642BOOST FMCW to CW

Part Number: AWR1642BOOST

Dear TI forum community,

Still struggling with getting AWR1642BOOST into continuous wave mode. I've followed beginning of DCA1000 Training Video (https://training.ti.com/dca1000-training-video?context=1128486-1139154-1136663 ) and successful reached the point where the SPI connection should be stablished. There it failed by flashing the firmware. Is DCA1000EVM needed to do all the necessities in order to put the AWR1642BOOST into CW mode as per that video? A step by step instructions for AWR1642BOOST would definitely help.

Thanks forward for your help.

    Yes,

    DCA1000 is required to capture the raw data.

    CW mode is configured in mmwave studio, then the data is captured using the DCA1000

    Thank you

    Hi Cesar,

    So there's no other solution to put the AWR1642BOOST into CW mode w/o the need of use additional DCA1000 even if I would not be interested into reading out the raw data. In my case there's no need to capture the data. I just need a source of CW at mm wave rage, e.g. 77GHz or the best would be to have the option to continuously sweep from 76GHz to 81GHz. Can this be achieved w/ AWR1642BOOST or can you think of similar price tagged solution to fulfill this?

    Thanks forward for your help.

    BR's,

    Martin

    Hi,
     
    Unfortunately there is no other solution immediately available
     
    Thank you

    Thanks Cesar. So the DCA1000 is really needed to accomplish the SPI connection in step 5 of mm wave studio. Is that correct?

    Please find attached screenshot of the last step able to accomplish. Not sure if there's a conflict of FW versions for BSS and MSS flashing in step 3 and 4. They are not matching as mentioned in video tutorial. Any thought about that one?

    As mentioned before our goal is just to set the AWR1642BOOSt into CW mode. No need to acquire data.

    If you don't need to capture raw data you will not need a DCA1000.

    You will only need a devpack

    Hi Cesa,

    DevPack could be a solution if it would be available and sill supported. But its availability is limited.

    Checking the link from you and corresponding Q&A gives answer that triggers more questions. Especially this answer:

    The latest SDK doesn’t support CW mode in the application.

    In this case the application is meant mmWave studio. Would that be correct? And if so, means we have to switch to old version (1.1) of SDK in order to use AWR1642BOOST+DCA100EVM in CW mode in mmWave studio?

    Thanks forward for clarifying the confusion.

    --------------------------------

    Q9. How to use capture data in continuous mode (CW mode) using SDK application?

    Answer: The recommendation is to use mmWave Studio with DCA1000EVM/DevPack to configure continuous mode (CW mode) data to mmWave Sensor. As mmWave Studio requires SPI interface to connect with mMWave sensor for any configuration, this SPI interface is available either on DevPack or DCA1000EVM not on BOOST EVM.

    The latest SDK doesn’t support CW mode in the application.

    Old version SDK v1.1 provided a capture demo where user can enable LVDS streaming and optionally enable the CW mode (RF Evaluation) as well.

    Hi,
     
    mmWave Studio and the SDK are two different tools.
     
    You will need to use mmWave Studio with DevPack.
     
    The other option is use mmWave Studio with DCA1000
     
    Thank you
