IIS2DULPX

Arduino library to support the IIS2DULPX 3D sensor

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:

IIS2DULPXSensor sensor(&dev_i2c);
sensor.begin();
sensor.Enable_X();

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

IIS2DULPXSensor sensor(&dev_spi, CS_PIN);  
sensor.begin();
sensor.Enable_X();

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

Read sensor.

int32_t sensor[3];
sensor.Get_X_Axes(sensor);  

Examples

• IIS2DULPX_DataLog_Terminal: This application shows how to get data from IIS2DULPX sensor and print them on terminal.

• IIS2DULPX_6D_Orientation: This application shows how to use IIS2DULPX sensor to find out the 6D orientation and display data on a hyperterminal.

• IIS2DULPX_Wake_Up_Detection: This application shows how to detect the wake-up event using the IIS2DULPX sensor.
