AWR1642BOOST: Short Time Fourier Transform - at real time

Part Number: AWR1642BOOST

Hi guys,

So I asked a related question here , and I was told to purchase another EVM. My next query, How can I edit the source code (which source files) to process the Short Time Fourier Transform such that I plot the results in real time just like how the Range Doppler heat map is plotted in real time?

    Hi,

    The mmWave SDK OOB demo uses UART to transfer the data to host PC. This transfer happens during the so called "inter-frame period" before the next frame starts.
    Depending on the frame rate, there will be limitations on the size of data that can be transferred.

    This is the reason why it was recommended to capture raw data using DCA1000 and process the raw data offline.

    If this is not the use case you desire, then you will be limited as far as the size of the data that can be transferred through UART at run time.

    It is important to understand these limitations before starting modifying the code

    thank you
