If you would like to use it, I have edited Examples -> Basic

long oldPosition  = -999;

void loop() {
  long newPosition = myEnc.read();

  int direction = 0;
  if (newPosition != oldPosition) { 

    direction = (newPosition > oldPosition) ? 1 : -1;

    oldPosition = newPosition;
    Serial.println(newPosition);
  }
}
