Measure magnetic field from BMM150 sensor

Since R2022b

Add-On Required: This feature requires the MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms add-on.

  • NVIDIA BMM150 sensor block

NVIDIA Jetson and NVIDIA DRIVE / Sensors / IMU sensors


The BMM150 block outputs the values of magnetic field along X, Y, and Z axes as measured by the BMM150 sensor connected to an NVIDIA® embedded board.

Magnetic field strength in micro Tesla (µT) measured by a BMM150 sensor connected to an NVIDIA embedded board, along the X, Y, and Z axes. The block outputs the magnetic field as a 1-by-3 vector.

Data Types: double

Status of magnetic field reading. 0 indicates that the data read is new and 1 indicates that the data read is not new.


This output port appears only if you select the Status parameter.

Data Types: int8

The I2C module to be used for communication to the BMM150 sensor. The number of I2C modules supported varies across different NVIDIA embedded boards.

Programmatic Use

Block Parameter: I2CModule
Type: character vector
Values: ''|positive integer
Default: ''

The I2C address used by BMM150 sensor communicating with the an NVIDIA embedded board. The default parameter value (0x13) corresponds to the I2C address used by the BOOSTXL-SENSORS BoosterPack™ Plug-in Module.

Programmatic Use

Block Parameter: I2CAddress
Type: character vector
Values: '0x10'|'0x11'|'0x12'|'0x13'
Default: '0x13'

Select this parameter to set Magnetic Field Status as one of the output ports.

Programmatic Use

Block Parameter: Status
Type: character vector
Values: 'on' | 'off'
Default: 'on'

Specify the preset value for the operating condition of BMM150 sensor while reading the values. The selection of one of the four preset values affects the electrical characteristics (like supply current) and the required output accuracy with respect to ODR and output noise.

Programmatic Use

Block Parameter: MagnetometerPreset
Type: character vector
Values: 'Low power'|'Regular'|'Enhanced'|'High accuracy'
Default: 'Low power'

Specify the output data type for the values read from BMM150 sensor. The default data type for an NVIDIA embedded boards is single. Use this parameter to change the values to double, if required.

Programmatic Use

Block Parameter: DataType
Type: character vector
Values: 'single'|'double'
Default: 'single'

Specify how often this block reads the data from the BMM150 sensor. When you set this parameter to -1, Simulink determines the best sample time for the block based on the block context within the model.

Programmatic Use

Block Parameter: SampleTime
Type: character vector
Values: scalar | vector
Default: '0.1'
