... The acceleration data may be accessed through an I2C/SPI interface thus making the device particularly suitable for direct interfacing with a microcontroller. The LIS3L02DS features a Data-Ready signal (DRY) which indicated when a new set of measured accel- eration data is available thus simplifying data synchronization in digital system employing the device itself. ...
