Freescale 12-axis Xtrinsic Sensor Platform Technology for Windows 8 / RT

Freescale announced the Xtrinsic Sensor Platform, a 12-axis sensor development reference platform for Windows 8. This 12-axis sensor platform includes several sensors by Freescale and other companies: Xtrinsic MMA8451Q 3-axis accelerometer Xtrinsic MAG3110 3-axis magnetometer Xtrinsic MPL3115A2 precision altimeter, pressure, and temperature sensor An analog ambient light sensor A selection of 3D gyroscopes are also supported This platform is powered by Freescale ColdFire+ MCF51JU128VHS MCU which combines, configures and processes sensor data with Freescale sensor fusion software to match the requirements of Windows 8/RT. Xtrinic sensor platform communicates with the host device via USB. It does not requires extra drivers as it uses standard HID drivers. You can watch the video below which is an introduction (including some technical details) and demo of the system. Strangely, I could not find a similar Freescale 12-axis reference design for Android or Linux, and I’m not sure why they would limit this hardware […]

Designing An Android Sensor Subsystem: Pitfalls and Considerations – Android Builder Summit 2012

Jen Costillo of Lab 126 discusses the Android sensor subsystem at the Android Builder Summit in February 2012. Abstract: This lecture will arm Android device architects with the tactical knowledge they need to navigate the Android Sensor subsystem and make knowledgeable design choices to improve user experience and improve battery performance. The talk will address: Hardware architecture and trade-offs including latency, power, and software architecture implications: Wake up events and power considerations Gesture Detection Algorithm processing location and considerations Testing methodologies (Creating tools to aid develop and collect data. This talk targets the kernel/firmware developer responsible for the sensor architecture. They should be familiar with kernel drivers, embedded systems, hardware bring up, Android services, and the C language. You can also download the presentation slides on linuxfoundation.org website.
