open-sensor-platform

Open Sensor Platform (OSP) is open source software built to enable systems with sensor hubs. It is a framework specifically for sensor data acquisition, communication, and interpretation. The embedded code is in C to allow easy compatibility with any CPU architecture or real-time operating system. The linux code allows easy implementation of sensor hub data up to an Application Processor (AP) an Android Hardware Abstraction Layer (HAL). The framework is simple and flexible enough to be extended to more use-cases.

This project can be used to support various embedded sensor applications such as:

  • Android KitKat compliant buffering sensor hubs,
  • always-on context aware hubs,
  • multi-function wearable devices.

Community Contributions

OSP encourages developers to focus on creating low-level applications for sensors rather than reinventing the wheel on the sensor interface. By open sourcing this software, community contributions can continue to develop this framework. Ports of OSP to other platforms can be contributed to this project.

OSP is released by Sensor Platforms Inc. under the Apache 2.0 license.

Trying it out

A reference sensor hub example is provided for easily available hardware:

  • an STEVAL board with ARM-CortexM3 based microprocessor and 9-axis sensors attached,
  • a Nexus7 tablet with KitKat connected over I2C to the STEVAL board as a sensor hub.

This example can be ported to a Cortex-M0+, or any other MCU or DSP architecture.

The example uses the Keil-MDK toolchain, but future releases will utilize gcc under Keil as well as full gcc/Makefile based build system.

The project uses the Keil RTX Real Time Operating system and will eventually leverage the platform agnostic CMSIS APIs.
