MMWAVEICBOOST: About getting ADC raw data with MMWAVEICBOOST Starter Kit

Part Number: MMWAVEICBOOST
Other Parts Discussed in Thread: IWR6843ISK, AWR1243, IWR6843

Hi,

I'm working with the MMWAVEICBOOST Starter Kit (MMWAVEICBOOST and IWR6843ISK Antenna Module), I want to extract the raw ADC data on my PC.

By reading similar forum threads, I see that users with AWR1243 module extract ADC raw data with the
"mmwave_example.exe" provided in the mmWave DFP.

Is it possible to obtain the raw ADC data with my Starter Kit (via SPI or in some other way)?
In the "mmWaveICBoost and Antenna Module" User Guide I see a dedicated section, but implies the use of DCA1000 module, I don't have it.

    Riccardo,

    Currently we only support ADC raw data capture with the DCA1000, this is because the amount of data produced by the EVM it too large for SPI,I2C or UART to support it.

    Thanks

    Hi Alex,

    Weeks ago, I programmed an AWR1243 module to obtain the ADC raw data. Using the
    mmWaveLink API provided, I set the frame periodicity to 1 s, and with this low data rate SPI can be used.
    I successfully read the raw data from the module via SPI, and I process them with my own software.

    In SDK User Guide Release 3.1.0 (Dec 15, 2018), in the table at page 17 there are the same indications for
    the frame periodicity for the xwr68xx/xwr18xx family:
    with enough frame periodicity, data can be shipped out with UART.

    Given this, how can I get the ADC raw data via either SPI or UART with the IWR6843 module?

    Many Thanks,

    Riccardo Spera

    Riccardo ,

    There are changes that you can do in order to achieve what you want, unfortunately we only support raw data capture with the DCA1000.
    In the past there was binaries that did support this but have been deprecated, you can still look in the source code and attempt to port it over, but you will be the one to handle this.
