BMM150 Magnetometer

Measure magnetic field from BMM150 sensor

Since R2022b

Add-On Required: This feature requires the Simulink Support Package for Raspberry Pi Hardware add-on.

Libraries:
Simulink Support Package for Raspberry Pi Hardware / Sensors / IMU Sensors

Description

The BMM150 block outputs the values of magnetic field along x-, y- and z- axes as measured by the BMM150 sensor connected to Raspberry Pi^® board.

Ports

Output

Magnetic Field — Magnetic field strength measured by a BMM150 sensor

row vector

Magnetic field strength (in µT) measured by a BMM150 sensor connected to Raspberry Pi board, along the x-, y- and z- axes, specified as a row vector [x,y,z].

Data Types: double

Magnetic Field Status — Status of magnetic field value

0 | 1

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

Dependencies

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

Data Types: int8

Parameters

I2C module — Module for communication

1 (default)

Specify the module on the board that you are using for I2C communication.

I2C address — I2C address of BMM150 sensor

0x13 (default) | 0x10 | 0x11 | 0x12

The I2C address used by BMM150 sensor communicating with the Raspberry Pi processor. The default parameter value (0x13) corresponds to the value mentioned in the Schematics section of the BOOSTXL-SENSORS BoosterPack^TM Plug-in Module User's Guide.

Status — Set output port for obtaining magnetic field status

on (default) | off

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

Preset value — Preset value for the operating condition of BMM150 sensor

Low power (default) | Regular | Enhanced | High accuracy

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.

Data type — Output data type for values from BMM150 sensor

single (default) | double

Specify the output data type for the values read from BMM150 sensor. The default data type for Raspberry Pi processors is single. Use this parameter to change the values to double, if required.

Sample time — Time interval to read data

-1 (default) | positive integer

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.
