could it be possible to have a mean in the AnalogIn class to set some kind of hysteresis or sensitivity to the analog inputs ?
The value read is often changing by only 1 or 2 units without user interaction, depending on many factors. But such behaviour can often mean that the value has not changed, in fact.
Or, if such ability is not possible, may be you could fire an event when the value is changing ? This way we could implement our own method.
