Measure magnetic field from BMM150 sensor

Since R2021b

  • BMM150

C2000 Microcontroller Blockset / Sensors


The BMM150 block outputs the values of magnetic field along x-, y- and z- axes as measured by the BMM150 sensor connected to C2000 board.

Magnetic field strength (in µT) measured by a BMM150 sensor connected to C2000 board, along the x-, y- and z- axes, specified as a row vector [x,y,z].

Data Types: double

Status of magnetic field 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 C2000 processors. You can find the supported I2C modules corresponding to the processor (which you selected for the Hardware Board parameter in the Simulink model) by opening the Configuration Parameters dialog box and checking the I2C specific tabs under Target hardware resources.

The I2C address used by BMM150 sensor communicating with the C2000 processor. The default parameter value (0x13) corresponds to the value mentioned in the Schematics section of the BOOSTXL-SENSORS BoosterPackTM Plug-in Module User's Guide.

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

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.

Specify the output data type for the values read from BMM150 sensor. The default data type for TI’s C2000™ processors is single. Use this parameter to change the values to double, if required.

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.
