Classes
struct	fsw::calibration::valve_position::Reading

Namespaces
namespace	fsw
	Motorized ball valve position: raw ADC counts -> % open.
namespace	fsw::calibration
	Output smoothing for calibrated PT pressure, per sensor uid (ESP32 and LabJack T7 alike).
namespace	fsw::calibration::valve_position

Functions
double	fsw::calibration::valve_position::counts_to_ma (uint32_t counts)
double	fsw::calibration::valve_position::ma_to_percent_open (double ma)
	% open, clamped to 0-100 (a loop a little outside 4-20 mA is still the end of travel).
Reading	fsw::calibration::valve_position::from_counts (uint32_t counts)

Variables
constexpr double	fsw::calibration::valve_position::kAdcMaxCounts = 4095.0
constexpr double	fsw::calibration::valve_position::kAdcRefVolts = 3.3
constexpr double	fsw::calibration::valve_position::kShuntOhms = 100.0
constexpr double	fsw::calibration::valve_position::kLoopMinMa = 4.0
constexpr double	fsw::calibration::valve_position::kLoopMaxMa = 20.0
constexpr double	fsw::calibration::valve_position::kNoSignalMa = 2.0
	Below this the loop is open or unpowered: no position, not "fully closed".
constexpr uint8_t	fsw::calibration::valve_position::kStatusOk = 1
	cal_status values published beside the position.
constexpr uint8_t	fsw::calibration::valve_position::kStatusNoSignal = 2
