IWR6843AOPEVM: mmWave Demo Visualizer GUI FFT

Part Number: IWR6843AOPEVM

Hello,

Is there a way to zero-pad the range FFT on the GUI by passing in the complex time domain signals?

If not, is there a way to access the complex values of the range profile?

It states in the demo visualizer code that for the azimuth-range heat map it takes the angle FFT over the zero Doppler components.

Thanks in advance.

    HI, there:

    SDK OOB demo has its own limitation.   For example, you can not program the range FFT size (zero-padding).   All the output of each SDK OOB demo can be found through SDK Doxygen documentation, such as file:///C:/ti/mmwave_sdk_03_05_00_04/packages/ti/demo/xwr68xx/mmw/docs/doxygen/html/index.html#output.    The azimuth static heatmap is actually generated in the visualizer, and zero Doppler bins are the ones sent to the visualizer through UART to compute the azimuth static heatmap.  file:///C:/ti/mmwave_sdk_03_05_00_04/packages/ti/demo/xwr68xx/mmw/docs/doxygen/html/index.html#tlv4 

    Best,
