AWR2243BOOST: Capturing data vis TSW1400EVM

Josel Go
Expert 5980 points
Part Number: AWR2243BOOST
Other Parts Discussed in Thread: DCA1000EVM, AWR1843BOOST, AWR1843

Hi Experts,

Good day.

Just to make sure that we did not
misunderstand anything, three more questions:

- Can we definitely use the TSW1400EVM hardware to capture raw data in
combination with our eval board AWR2243BOOST?
- Does the capturing happen in 'real-time' or is block-based and
therefore delayed (as the FPGA reads the data from the memory and
transmits it via the onboard high-speed USB to SPI converter to the host
PC)?
- Do we need to order any additional equipment (e.g. a specific cable, ...)?

Regards,

Josel

    Hello,

    Yes, it is possible to capture raw data with AWR2243BOOST and TSW1400EVM but you will need an additional board called the mmWave DevPack. The DevPack was deprecated several years ago and is no longer being sold, so if you do not already have one then you will not be able to get one. Without this board it is not possible to use the TSW1400 with the AWR2243BOOST.

    Capture is not in real time. The data is sent to the FPGA and is then sent to the PC over USB. It is not possible to do real time streaming for raw ADC capture with a PC.

    We recommend to use the DCA1000EVM instead of TSW1400EVM. With DCA1000EVM you can interface directly with the AWR2243BOOST without the need for the DevPack. Again, this will not be real time raw data capture. The data is sent to FPGA and is then sent out over Ethernet to the PC and stored in a .bin file.

    Hi Adrian,

    Thank you for your response. We do not have the mmWave DevPack, hence the TSW1400EVM is no option. We would anyhow prefer the DCA1000EVM, but unfortunately, it seems not to be available in the near future by any distributor.
    Can we find a solution that we return the AWR2243BOOST (as there is no possibility for us to use it because the additionally required devices are simply not available) and we receive an evaluation board capable of capturing raw data (or something ‘similar’ like the range fft or the range doppler map)?

    Please advise

    Regards,

    Josel

    Hello Josel,

    I need to check with my manager. Maybe you can mail the board to me directly and we can mail you an AWR1843BOOST. You will not be able to capture raw data on any of the boards without DCA1000, but the AWR1843BOOST and send the processed data out over UART if that is sufficient for your needs. 

    Regards,

    Adrian

    Hi Adrian,

    Is this means the AWR1843BOOST can do the work alone?
    Are you recommend replacing the AWR2243BOOST with AWR1843BOOST by mailing you the AWR2243BOOST and in return you will mail back the  AWR1843BOOST?

    Regards,

    Josel

    AWR1843BOOST can send processed data over UART with no other board. It cannot send raw ADC data. If your application requires capturing raw ADC data then we do not have a solution that will work without DCA1000EVM.

    Yes, if you can give me the AWR2243BOOST I will give you the AWR1843BOOST.

    Hi Adrian,

    Good day.

    Could you please tell me what exactly 'processed' data means for the AWR1843, e.g.,
    • filtered and/or resampled ADC raw data
    • data after the range FFT
    • range-Doppler map data
    • or just a target list?

    Regards,

    Josel

    Hello,

    Sorry, I had to go out of town for business trip and could not get back to you. Processed data would typically be the range profile, doppler profile, etc. You can refer to the SDK doxygen for example of the out of box demo data that is sent over UART. This would be located in the following directory:

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw\docs\doxygen\html\index.html

    Regards,
