Data brief

Description

The iNEMO engine is a new, advanced software
engine that fuses accelerometer, gyroscope and
magnetometer data to deliver accurate and
reliable motion-sensing information that is easy to
integrate into smart consumer devices.

The iNEMOEngine_LI3 Sensor Fusion
demonstration firmware comes with the iNEMO
Engine. The library is available from version 2.3.0
of the STEVAL-MKI062V2 iNEMO suite as source
code for the on-board STM32F103. The library is
compatible with all the STM32 hardware
platforms.
