Dannis_mbed 0:81b21910454e 8 /** This Class handles a rotary encoder with mechanical switches and an integrated pushbutton
Dannis_mbed 0:81b21910454e 9 * It uses two pins, one creating an interrupt on change.
Dannis_mbed 0:81b21910454e 10 * Rotation direction is determined by checking the state of the other pin.
Dannis_mbed 0:81b21910454e 11 * Additionally a pushbutton switch is detected
Dannis_mbed 0:81b21910454e 12 *
Dannis_mbed 0:81b21910454e 13 * Operating the encoder changes an internal integer value that can be read
Dannis_mbed 0:81b21910454e 14 * by Get() or the operator int() functions.
Dannis_mbed 0:81b21910454e 15 * A new value can be set by Set(value) or opperator=.
