Struct Calibration 

pub struct Calibration { /* private fields */ }

The per-chip calibration coefficients read from the sensor’s calibration registers.

These are factory-programmed and constant for a given device, so they are read once at start-up and reused for every measurement.

Implementations

impl Calibration

pub fn from_registers(temp_press: &[u8; 26], humidity: &[u8; 7]) -> Calibration

Parses the calibration coefficients from the two register blocks.

The split-and-shifted packing of dig_h4 and dig_h5, which share a byte, is done exactly as the datasheet specifies.

Arguments

• temp_press - the 26 bytes read from 0x88..=0xA1.
• humidity - the 7 bytes read from 0xE1..=0xE7.

Returns

The decoded calibration.

pub fn compensate(&self, raw: &RawMeasurement) -> Measurement

Compensates a raw measurement into temperature, pressure, and humidity.

Temperature is computed first because its intermediate t_fine term feeds the pressure and humidity formulas, exactly as the reference code shares it.

Arguments

• raw - the uncompensated readings from the data registers.

Returns

The compensated Measurement.

Trait Implementations

impl Clone for Calibration

fn clone(&self) -> Calibration

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Calibration

impl Debug for Calibration

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Calibration

impl PartialEq for Calibration

fn eq(&self, other: &Calibration) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
