Arduino FFT Library Notes: For a faster frequency analysis library, check out the FHT! The serial output of the examples is in binary, not ASCII. This means it will not be human readable on the serial port. Change serial.write() to serial.print() to fix this. You may need to writ...
How to Use the FHT Library These are all the same as the FFT library, so they are just linked from here. Note that the FHT functions will be called fht_function rather than fft_function, and that you only need to fill 1 data bin for the FHT, i.e. fht_input[i] only goes from ...
