Could you elaborate as to how..... Especially in a
power down condition where upon one could loose track.
I take it, there is some trick, as many devices, use
relative rather than absolute positioning. WIthout a
home position to index off of, it would seem one could
loose the position of the pointer if it were turned
and power was off.... Or is it interrupt driven such
that the micro stays alive and wakes up should the
shaft be turned???
