Simulink Coder Support Package for STMicroelectronics Nucleo Boards / Sensors

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.

端子

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.

データ型: 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.

データ型: 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.

データ型: int8

Parameters

Main Tab

I2C module — Specify I2C module

2 (既定値) | 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 (既定値) | off

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

Temperature (℃) — Set output port for reading temperature

on (既定値) | 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 (既定値) | on

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

Sample time — Time interval to read data

-1 (既定値) | 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.

Advanced Tab

Magnetometer range — Full scale for measuring magnetic range

±2g (既定値) | ±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 (既定値) | 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.
