STEVAL-MKI121CD1

AHRS for Discovery-M1
  • active Active

The STEVAL-MKI121CD1 is a CD which includes the AHRS algorithm as a pre-compiled library (in .lib format) for Discovery-M1 (order code STEVAL-MKI121V1).

The AHRS algorithm provides 3D orientation, combining data from 3x gyroscope and 6x e-Compass sensors.

The outputs of all sensors are processed by the STM32F103 microcontroller in the INEMO-M1, and fused in a Kalman filter to compensate for drift and provide stable orientation.

The AHRS firmware is only a demonstrator and it is used to run the 3D Demo Cube of the Discovery-M1 iNEMO Suite.
