ABSTRACT:
A digital display updated by inputs from a manual control having a plurality of tactile detents. A counter is loaded with a predetermined number and then decremented at a fixed rate until the number reaches one. The fixed rate is either the program cycle time of a microprocessor embodiment or the clock time of a circuit embodiment. Whenever a detent of the control is detected, the then current value of the counter is added to or subtracted from the display and the counter is again loaded with the predetermined number.
