Detailed Description

Potentiometer component — smoothed, calibrated ADC with su output.

Pot is a source adapter (L1/L2, FDP-072): raw ADC counts in, normalized signal units out. Pipeline: raw → EWMA (raw domain) → two-point calibration → su [0, 1]. Deadband operates in su.

Acquisition is owned by the component: feed values with update(), or read straight from a DMA scan buffer with update_dma() (ISR-safe).

Usage: sbl::components::input::Pot knob; knob.update_dma(adc_buf, 0); if (knob.changed()) { apply(knob.value()); } // deadbanded su widget.set_cutoff_su(knob.smoothed()); // full-resolution su
