Optimized for minimizing power consumption

STMicroelectronics (hereinafter ST), a semiconductor company, is supporting the development of convenient motion recognition applications by adding three types to its free software library, Open.MEMS.

A new software library implements ST's motion-sensing technology on the ARM Cortex-M 32-bit microcontroller STM32. This enables contextual awareness capabilities in mobile, wearable, and IoT (Internet of Things) applications.



OpenDotMems detects human behavior by collecting data using inertial sensors embedded in the final product. In addition, optimized for minimizing power consumption, it appears suitable for fitness and healthcare applications based on portable/wearable platforms that monitor human physical activity in real-time over long periods.

The three new software packages are, first, the osxMotionAR Activity Recognition package, which identifies various movements and movement scenarios; the osxMotionCP Carry Position package, which detects the carrying position of a device with a built-in motion sensor; and the osxMotionGR Gesture Recognition package, which recognizes the usage movements of a portable device.

The Open.MEMS library is included in the X-CUBE-MEMS1 extension software package for driving the X-NUCLEO-IKS01A1 motion MEMS and environment sensor expansion board, based on the software development tool STM32Cube.

Each software package includes pre-compiled libraries for universal development environments and examples that allow for easy and convenient evaluation of the unique features and performance of ST's MEMS motion sensors.
