Simple Android Sensors HAL for Android integration without any algorithm.
This repository provides a simple Android Sensors HAL for integrating InvenSense chips inside Android system. It doesn't provides any calibration or fusion algorithms inside.
Beware that this integration is not compliant with Android CDD because of the lack of calibration algorithms for gyroscope and magnetometer.
The sensors/ folder contains the Android Simple Sensors HAL 1.0.
The subhalv2_1/ folder contains an Android SubHal v2.1 wrapper loading the Sensors HAL 1.0 for implementing SubHal v2.1 interface.
