ESP8266 Community Forum

Hi,

my first day in this fantatastic forum.
I searched already this forum about FFT or FHT implementations running on ESP8266. Nothing found.

Has somebody ported or tested the Arduino FFT.h or FHT.h libraries running on ESP8266?
For your reference:
- http://wiki.openmusiclabs.com/wiki/ArduinoFHT (Fast Hartley Transform)
- http://wiki.openmusiclabs.com/wiki/ArduinoFFT (Fast Fourier Transform)

Has somebody implemented a algorithm to convert time domain samples into the frequency domain?
Can somebody point me to C-Code algorithms running on ESP8266?

TX,
Timo

I tried. The "Openmusiclabs" code is partly in assembler. Seems to be incompatible with ESP. Not supprised. Looking for an all C++ FFT or FHT.

This version will compile for ESP

hi guys i needed the solution to this as well, found arduinoFFT (https://github.com/kosme/arduinoFFT) little helpful but i'm not able to understand how the developer presents the final FFT output. If any of you guys could figure it out please help
