mbedalvaro | 0:df6fdd9b99f0 | 7 | /* This Class handles a rotary encoder like the one from Pollin electronic (Panasonic EVEP...). |
mbedalvaro | 0:df6fdd9b99f0 | 8 | * It uses two pins, one creating an interrupt on change. |
mbedalvaro | 0:df6fdd9b99f0 | 9 | * Rotation direction is determined by checking the state of the other pin. |
mbedalvaro | 0:df6fdd9b99f0 | 10 | * |
mbedalvaro | 0:df6fdd9b99f0 | 11 | * Operating the encoder changes an internal integer value that can be read |
mbedalvaro | 0:df6fdd9b99f0 | 12 | * by Get() or the operator int() functions. |
mbedalvaro | 0:df6fdd9b99f0 | 13 | * A new value can be set by Set(value) or opperator=. |
