How to store and manage ADC values in a 2D array for FFT processing in an FMCW radar system
You’d create the 2D matrix first, something like
float32_t fft_matrix[20][512];. Then, each time your fft_in array updates, you copy its contents into the next available row of your matrix. You can do this in your existing loop where you process the FFT. @Sterling9 replies
