I tried to use CMSIS DSP library for FFT implementation on STM32F407. I based my project on Tilen MaJerle library. I sample data with on board ADC and fill the input buffer with function TM_FFT_AddToBuffer(TM_FFT_F32_t* FFT, float32_t sampleValue). H...

I see, you are right. But if we put aside the real-time requirement (anyway I measure AC signal and then FFT process the data and wait for the result about a second or so on) what techniques would you recommend me? The point is for them to be applica...
