Description
The LIS3MDL Magnetometer Sensor block outputs the values of magnetic field strength along x-, y- and z- axes as measured by the LIS3MDL Magnetometer sensor connected to Nucleo/STM32L475-Discovery board. The block also outputs the temperature as read by the LIS3MDL Magnetometer sensor.
Ports
Output
Magnetic Field — Magnetic field strength measured by LIS3MDL sensor
row vector
Magnetic field strength (in µT) measured by LIS3MDL sensor connected to Nucleo/STM32L475-Discovery board, along the x-, y- and z- axes, specified as a row vector [x,y,z].
Dependencies
This output port appears only if you select the Magnetic Field (µT) parameter.
Data Types: double
Temperature — Temperature measured by LIS3MDL sensor
scalar
Temperature (in ℃) measured by LIS3MDL sensor connected to Nucleo/STM32L475-Discovery board.
Dependencies
This output port appears only if you select the Temperature (℃) parameter.
Data Types: double
Status — Status of magnetic and temperature measurements
-1
| 0
| 1
Status of magnetic and temperature measurements, specified as a 1-by-2 vector.
0
indicates that the data read is new, 1
indicates that the data read is not new, and -1
indicates that the
corresponding output is not selected.
Dependencies
This output port appears only if you select the Status parameter.
Data Types: int8
Parameters
Main Tab
I2C module — Specify I2C module
2
(default) | positive integer
Specify the I2C module on the board. The I2C bus frequency, serial clock (SCL) pin and serial data (SDA) pin are taken according to the corresponding I2C module entry in the configuration parameters.
Magnetic Field (µT) — Set output port for reading magnetic field
on
(default) | off
Select this parameter to set Magnetic Field as one of the output ports.
Temperature (℃) — Set output port for reading temperature
on
(default) | off
Select this parameter to set Temperature as one of the output ports.
Magnetic Field Status — Set output port for obtaining magnetic field status
off
(default) | on
Select this parameter to set Magnetic Field Status as one of the output ports.
Sample time — Time interval to read data
-1
(default) | positive integer
Specify how often this block reads the data from the LIS3MDL 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.
Magnetometer range — Full scale for measuring magnetic range
±2g
(default) | ±4g
| ±8g
Select the full scale for measuring linear acceleration (the range of acceleration that the sensor needs to measure).
Magnetometer output data rate — Rate at which magnetometer data is sampled
0.625 Hz
(default) | 1.25 Hz
| 2.5 Hz
| 5 Hz
| 10 Hz
| 20 Hz
| 40 Hz
| 80 Hz
Select the output data rate at which magnetometer data is sampled.
