Fast Fourier Transform using the ARM CMSIS Library within the STM32 MCUs

Описание к видео Fast Fourier Transform using the ARM CMSIS Library within the STM32 MCUs

The video explains how to implement the Fourier Transform using the ARM MATH CMSIS library.

Key lines:
arm_rfft_fast_instance_f32 fft_instance;
arm_rfft_fast_init_f32(&fft_instance, FFT_LENGTH);
arm_rfft_fast_f32(&fft_instance, input_fft, output_fft, 0);
arm_cmplx_mag_f32(output_fft, output_fft_mag, FFT_LENGTH/2);
