Implementation for LIS2DH12 basic usage. The implementation supports different resolutions, samplerates, high-passing, activity interrupt and FIFO.

Requires STM lis2dh12 driver, available on GitHub under BSD-3 license. Requires "application_config.h", will only get compiled if LIS2DH12_ACCELERATION is defined. Requires floats enabled in application.
