// I2C device class (I2Cdev) demonstration Arduino sketch for MPU6050 class using DMP (MotionApps v2.0)
// 6/21/2012 by Jeff Rowberg <jeff@rowberg.net>
// Updates should (hopefully) always be available at https://github.com/jrowberg/i2cdevlib
//
// Changelog:
//     2012-06-21 - added note about Arduino 1.0.1 + Leonardo compatibility error
//     2012-06-20 - improved FIFO overflow handling and simplified read process
//     2012-06-19 - completely rearranged DMP initialization code and simplification
//     2012-06-13 - pull gyro and accel data from FIFO packet instead of reading directly
//     2012-06-09 - fix broken FIFO read sequence and change interrupt detection to RISING
//     2012-06-05 - add gravity-compensated initial reference frame acceleration output
//                - add 3D math helper file to DMP6 example sketch
//                - add Euler output and Yaw/Pitch/Roll output formats
//     2012-06-04 - remove accel offset clearing for better results (thanks Sungon Lee)
//     2012-06-01 - fixed gyro sensitivity to be 2000 deg/sec instead of 250
//     2012-05-30 - basic DMP initialization working

NOTE: In addition to connection 3.3v, GND, SDA, and SCL, this sketch
depends on the MPU-6050's INT pin being connected to the Arduino's
external interrupt #0 pin. On the Arduino Uno and Mega 2560, this is
digital I/O pin 2.
* ========================================================================= */

/* =========================================================================
NOTE: Arduino v1.0.1 with the Leonardo board generates a compile error
when using Serial.write(buf, len). The Teapot output uses this method.
The solution requires a modification to the Arduino USBAPI.h file, which
is fortunately simple, but annoying. This will be fixed in the next IDE
release. For more info, see these links:
