mbedalvaro 42:c4e9c1116af4 7 /* This Class handles a rotary encoder like the one from Pollin electronic (Panasonic EVEP...).
mbedalvaro 42:c4e9c1116af4 8 * It uses two pins, one creating an interrupt on change.
mbedalvaro 42:c4e9c1116af4 9 * Rotation direction is determined by checking the state of the other pin.
mbedalvaro 42:c4e9c1116af4 10 *
mbedalvaro 42:c4e9c1116af4 11 * Operating the encoder changes an internal integer value that can be read
mbedalvaro 42:c4e9c1116af4 12 * by Get() or the operator int() functions.
mbedalvaro 42:c4e9c1116af4 13 * A new value can be set by Set(value) or opperator=.
