Class Bmp280Calibration

Namespace

Pamoja.Sensors

Assembly

Pamoja.Sensors.dll

A BMP280's factory calibration, read once out of the registers and reused for every measurement, since the compensation the datasheet specifies needs it.

Constructors

Bmp280Calibration(ReadOnlySpan<byte>)

Builds a calibration from the bytes read out of the registers.

public Bmp280Calibration(ReadOnlySpan<byte> bytes)

Parameters

bytes ReadOnlySpan<byte>

The 24-byte coefficient block from 0x88.

Exceptions

PamojaException

The block is the wrong length.

Methods

Coefficients()

Reads the individual coefficients the compensation is computed from.

public PamojaBmp280Coefficients Coefficients()

Returns

PamojaBmp280Coefficients

The coefficients as the datasheet names them.

Exceptions

PamojaException

The calibration has been disposed.

Compensate(ReadOnlySpan<byte>)

Turns a six-byte burst read into a compensated reading.

public Bmp280Reading Compensate(ReadOnlySpan<byte> measurement)

Parameters

measurement ReadOnlySpan<byte>

The six measurement registers from 0xF7.

Returns

Bmp280Reading

The compensated reading.

Exceptions

PamojaException

The measurement is not six bytes.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

ToBytes()

Rebuilds the register bytes the coefficients were read from.

public byte[] ToBytes()

Returns

byte[]

The 24 coefficient bytes in register order.

Exceptions

PamojaException

The calibration has been disposed.
