STEVAL-MKI121CD1AHRS for Discovery-M1
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.
- AHRS library in .lib format for iNEMO Suite 3D Demo Cube
- Headings, pitch and roll
- Max ODR of 50 Hz
- System requirements:
- 11 Kbyte Flash memory
- 6 Kbyte RAM
