MMWCAS-RF-EVM: Questions Regarding the EVM

TI-CSC
Genius 12965 points
Part Number: MMWCAS-RF-EVM
Other Parts Discussed in Thread: AWR2243, MMWCAS-DSP-EVM, AWR2944, TIDEP-01012

Hello E2E Experts,

Good day.

 I have a few more questions, still about your MMWCAS-RF-EVM:

  • If we buy the MMWCAS-RF-EVM board and the MMWCAS-DSP-EVM in order to have a development kit, is the software included or not? Is the software compatible with any version of the MMWCAS-DSP-EVM board and especially with the AWR2243 chip? Because on your website it is specified “mmWave studio GUI tools for 2nd-generation parts (AWR2944)” but the MMWCAS-RF-EVM board seems to include an AWR2243 chip only.
  • Is it simple to configure the radar in MIMO mode or TXBF mode?
  • Does it come with a basic configuration that allows a plug-and-play start, or do we have to configure it completely before using it?
  • To achieve our goal, is it preferable to use the MIMO mode or the TXBF mode? What is the typical use case of each?
  • Do we have to perform the calibration (frequency and gain/phase)?
  • In beamforming mode, what does represent the yellow/green line in the center of the image of the radar on Figure 31 p.29 of the document TIDEP-01012?
  • Do you provide configuration files?

Regards,

CSC

    Hi,

    The cascade kit,  MMWCAS-RF-EVM+MMWCAS-DSP-EVM, is a black box capture kit that allows to capture raw data.

    The kit can be configured through mmWave Studio GUI or through matlab scripts provided in the mmWave studio package.

    The raw data is processed with matlab scripts provided in the mmWave Studio package.

    The cascade kit is not intended for real time development. The raw data is captured on the PC and must be post processed after capture is complete.

    The cascade kit does not include a plug and play. It required to follow the steps provided.

    I recommend that before buying you download mmWave Studio v. 3.0.0.14 and read the provided cascade user guide

    Thank you

    Hello Cesar,

    Good day.

    We still have some questions:

    • Would it be possible that you to provide us with some configuration files that could match our needs? What configuration did you use to realize your demonstration video?
    • Is the software compatible with any version of the MMWCAS-DSP-EVM board and especially with the AWR2243 chip? Because on your website it is specified “mmWave studio GUI tools for 2nd-generation parts (AWR2944)” but the MMWCAS-RF-EVM board seems to include an AWR2243 chip only.
    • Do we have to perform the calibration (frequency and gain/phase)? This calibration is mentioned in your document Design Guide TIDEP-01012 p.13 (part 3.3).
    • In beamforming mode, what does represent the yellow/green line in the center of the image of the radar on Figure 31 p.29 of the document Design Guide TIDEP-01012?

    Hi CSC,

    • Would it be possible that you to provide us with some configuration files that could match our needs? What configuration did you use to realize your demonstration video?
      The studio comes with a few sample configuration files which can be used as a reference to create one as per your requirements.
    • Is the software compatible with any version of the MMWCAS-DSP-EVM board and especially with the AWR2243 chip? Because on your website it is specified “mmWave studio GUI tools for 2nd-generation parts (AWR2944)” but the MMWCAS-RF-EVM board seems to include an AWR2243 chip only.
      This version (3.0.0.14) is compatible with all versions of the MMWCAS-DSP-EVM / MMWCAS-RF-RVM.
    • Do we have to perform the calibration (frequency and gain/phase)? This calibration is mentioned in your document Design Guide TIDEP-01012 p.13 (part 3.3).
      It is recommended that you perform the same once per EVM.
    • In beamforming mode, what does represent the yellow/green line in the center of the image of the radar on Figure 31 p.29 of the document Design Guide TIDEP-01012?
      This corresponds to the zero doppler bin. This usually describes the static objects in your scene.

    Additionally, you can refer to the Processor Radar SDK 3.8 which have example applications for TXBF and MIMO within which you can use as a reference for your development.
