#include <pot_calibration.hpp>

Public Member Functions
uint32_t	normalize (uint32_t raw) const
	Normalize raw ADC reading to [0, kOutputMax], clamped.

Static Public Member Functions
static PotCalibration	from_two_point (uint32_t ccw_reading, uint32_t cw_reading)
static constexpr PotCalibration	default_patch_init ()
	Default for Daisy Patch.init() (inverted, ~0–33000 range).
static constexpr PotCalibration	default_full_range ()
	Default full-range (no calibration needed).

Public Attributes
uint32_t	raw_min = 0
	ADC reading at logical minimum (CCW after inversion)
uint32_t	raw_max = 65535
	ADC reading at logical maximum (CW after inversion)
bool	inverted = false
	true if high ADC value = CCW (knob turned left)

Static Public Attributes
