| arduinoFFT | A library for implementing floating point Fast Fourier Transform calculations on the Arduino framework. |
| fix_fft | A library for implementing fixed-point in-place Fast Fourier Transform on Arduino. It sacrifices precision and instead it is way faster than floating-point implementations. |
| flex_DST | A library for observing DST according to user predefined parameters. |
| timestamp32bits | A library for calculating UNIX-like timestamps for dates AFTER January 1, 1970 or January 1 of whichever year is selected as EPOCH. |
