LIS2MDL

Arduino library to support the LIS2MDL high-performance 3-axis magnetometer

API

This sensor uses I2C or SPI to communicate. For I2C it is then required to create a TwoWire interface before accessing to the sensors:

TwoWire dev_i2c(I2C_SDA, I2C_SCL);  
dev_i2c.begin();

For SPI it is then required to create a SPI interface before accessing to the sensors:

SPIClass dev_spi(SPI_MOSI, SPI_MISO, SPI_SCK);  
dev_spi.begin();

An instance can be created and enabled when the I2C bus is used following the procedure below:

LIS2MDLSensor Magneto(&dev_i2c);
Magneto.begin();	
Magneto.Enable();

An instance can be created and enabled when the SPI bus is used following the procedure below:

LIS2MDLSensor Magneto(&dev_spi, CS_PIN);
Magneto.begin();
Magneto.Enable();

The access to the sensor values is done as explained below:

Read magnetometer.

int32_t magnetometer[3];
Magneto.GetAxes(magnetometer);
