-A CircuitPython class for scaling a range of input values into indexed/quantized output values. Adjustable output slice hysteresis is used to provide dead-zone squelching.
+Range_Slicer is a general-purpose analog value converter that linearly scales the input then quantizes it into a collection of precise output slice values. The class detects input value changes and applies selectable hysteresis when slice edge thresholds are reached to eliminate dead-zone noise issues without filtering delays. Applications include converting rotary knob position to discrete ranges of MIDI values, analog signal noise processing, level detection, rotary switch emulation, and signal display.
