Class Bmm150I2cBmi270

Namespace

Iot.Device.Bmi270

Assembly

Iot.Device.Bmi270.dll

Provides I2C access to a BMM150 magnetometer connected through the BMI270's auxiliary (secondary) I2C master interface.

public class Bmm150I2cBmi270 : Bmm150I2cBase

Inheritance

object

Bmm150I2cBase

Bmm150I2cBmi270

Remarks

On the M5Stack CoreS3, the BMM150 (address 0x10) is physically wired to the BMI270's auxiliary I2C bus. This adapter routes Bmm150 register reads and writes through the BMI270's AUX registers so the magnetometer appears as a normal I2C device.

Constructors

Bmm150I2cBmi270(byte)

Initializes a new instance of the Bmm150I2cBmi270 class.

public Bmm150I2cBmi270(byte auxDeviceAddress)

Parameters

auxDeviceAddress byte

The 7-bit I2C address of the BMM150 on the auxiliary bus (typically 0x10).

Methods

ReadByte(I2cDevice, byte)

public override byte ReadByte(I2cDevice i2cDevice, byte reg)

Parameters

i2cDevice I2cDevice

reg byte

The register to read.

Returns

byte

The register value.

ReadBytes(I2cDevice, byte, SpanByte)

Read bytes on a specific Bmm150 register.

public override void ReadBytes(I2cDevice i2cDevice, byte reg, SpanByte readBytes)

Parameters

i2cDevice I2cDevice

reg byte

The register to read.

readBytes SpanByte

Span of byte to store the data read.

WriteRegister(I2cDevice, byte, byte)
