Converting from other library #2

Closed francescofact closed 4 years ago

francescofact commented 4 years ago

Hi, i have some code for arduino written in C with the library "arduinoFTT.h". I'm using an esp32 with micropython firmware so i need to translate that code to micropython. The ftt related lines are: FFT.Windowing(vReal, SAMPLES, FFT_WIN_TYP_HAMMING, FFT_FORWARD); FFT.Compute(vReal, vImag, SAMPLES, FFT_FORWARD); FFT.ComplexToMagnitude(vReal, vImag, SAMPLES); where the values are these:

define SAMPLES 512

double vReal[SAMPLES];

I can't understand how to convert to this library. Can someone help me please?

This fft library uses STM assembler: it is intended for Pyboards and won't run on ESP32. I suggest you raise a general query on the forum.
