MPU-6050 Triple Axis Accelerometer & Gyro Breakout
Introduction
Motion interface is rapidly becoming a key function in many consumer electronics devices including smartphones, tablets, gaming consoles, and smart-TVs as it provides an intuitive way for consumers to interact with electronic devices by tracking motion in free space and delivering these motions as input commands.The MPU-6050 is the world’s first and only 6-axis MotionTracking devices designed for the low power, low cost, and high performance requirements of smartphones, tablets and wearable sensors.By combining a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor(DMP) capable of processing complex 9-axis MotionFusion algorithms. The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor.For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g.

Usage
Jeff Rowberg’s i2cdevlib is by far the best way to configure the chip and get raw data at the moment. With his code, you’ve got a nice 6-axis solution in a tiny footprint.
Noah Zerkin wrote an Arduino sketch to get precomputed quaternions out of the MPU6050. It just reproduces the behavior of the Invensense example firmware for the Atmel UC3 Xplained board. The sketch still haven’t gotten calibration saving and loading working, so it still drifts for a bit, but stabilizes if you leave the sensor in a no-motion state for a little bit. You can use it with the Invensense Teapot/Mouse Demo app , or modify the packet structure for your own app like Fabio's FreeIMU_cube Processing sketch here.
