SparkFun MPU-9250 Digital Motion Processor (DMP) Arduino Library

SparkFun MPU-9250 (SEN-13762)

Advanced Arduino library for the Invensense MPU-9250 inertial measurement unit (IMU), which enables the sensor's digital motion processing (DMP) features. Along with configuring and reading from the accelerometer, gyroscope, and magnetometer, this library also supports the chip's DMP features like:

• Quaternion calculation
• Pedometer
• Gyroscope calibration
• Tap detection
• Orientation dtection

For help getting started with this library, refer to the Using the MPU-9250 DMP Arduino Library section of the 9DoF Razor IMU M0 Hookup Guide.

Note: This library currently only supports and is tested on SAMD processors. It's a major part of the SparkFun 9DoF Razor IMU M0 firmware.

If you're looking for an AVR-compatible (Arduino Uno, SparkFun RedBoard, etc.) library, check out the SparkFun MPU-9250 Breakout Library, which provides access to all standard MPU-9250 sensor-readings.
