AWR1642BOOST: Export Range Profile, Heatmap through mmWave Demo Visualizer

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642

Hi, TI team,

I want to ask that is it possible to export Range Profile, Range-Doppler Heatmap, and Range-Azimuth Heatmap through mmWave Demo Visualizer?

(Because there was a post discussed about this. https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1046113/iwr6843aopevm-structure-of-range-profile-data-in-out-of-box-demo?tisearch=e2e-sitesearch&keymatch=Out-of-Box%252525252520export%252525252520range%252525252520profile#)

So, is it correct that if I connect my AWR1642 kit to the mmWave Demo Visualizer, and then select some options sort of Range Profile and Heatmap in Plot Selection, then press "Record Start" button in the PLOTs, those chosen data will all be save as .dat file?

Many thanks.

Shihyu.

    Hi,

    Yes, this is possible.

    Please notice following:

    • You may have to increase the frame duration in the file configuration to allow for sufficient time to transfer the data through uart

    Example:

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\xwr16xx\mmw\profiles\profile_2d.cfg

    "frameCfg 0 1 32 0 100 1 0" frame duration is 100ms. You can increase to 500ms for example: "frameCfg 0 1 32 0 500 1 0"

    • There are some python scripts provided to parse the recorded data.

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\parser_scripts

    Thank you

    Hi,

    。According to the increasing frame duration in the configuration file, are there any method which can guide me to calculate a feasible duration?

    Thank you

    Since the speed of the UART is around 900bps. You can estimate how long the transfer time will be. To be safe, extend by 20-30%

    Thank you
