60 * Quadrature explanation since it's not plainly obvious how this works:
61 *
62 * If either of the quadrature lines change, we can look up the combination
63 * of previous state and new state in the table above (enc_state[] below)
64 * and it tells us whether to add 1, subtract 1, or no change from the sum (enc_position).
65 * This also gives us a nice debounce, since each state can only have 1 pin change
66 * at a time. I didn't come up with this, but I've used it before and it works well.
67 *
68 * Old state is 2 higher bits, new state is 2 lower bits of enc_current_state. */
