Arduino library to support the LIS3DHH 3D accelerometer

This sensor uses SPI to communicate.

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 SPI bus is used following the procedure below:

LIS3DHHSensor 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);
