Libraries:
C2000 Microcontroller Blockset / 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 C2000 board.

Examples

Read Data from IMU and Environmental Sensors

Use C2000™ Microcontroller Blockset to read data from the BMI160 Inertial Measurement Unit (IMU) sensor and BME280 Environmental sensor that are part of the BOOSTXL-SENSORS BoosterPack™ plug-in module.

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 C2000 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

I2C_A (default)

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.

I2C address — I2C address of BMM150 sensor

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

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 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 TI’s C2000™ 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.
