Arduino library to support the LIS2DW12 3D accelerometer

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:

LIS2DW12Sensor Accelero(&dev_i2c);
Accelero.begin();
Accelero.Enable_X();

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

LIS2DW12Sensor Accelero(&dev_spi, CS_PIN);  
Accelero.begin();
Accelero.Enable_X();

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

Read accelerometer.

int32_t accelerometer[3];
Accelero.Get_X_Axes(accelerometer);
