| A library for interfacing with the tinyAVR analog comparator(s).      |
| Developed in 2019 by MCUdude    https://github.com/MCUdude/           |
| Ported to tinyAVR 2021 by Spence Konde for megaTinyCore               |
| https://github.com/SpenceKonde/megaTinyCore                           |
|                                                                       |
| In this example we use the negative and positive input 0 of the       |
| comparator. The output goes high if the positive input is higher than |
| the negative input, and low otherwise. We'll also use the built-in    |
| hysteresis functionality to prevent spurious signals while the        |
| voltage on the two pins is very close                                 |
