// 2013-05-06 - add Francesco Ferrara's Fastwire v0.24 implementation with small modifications
|
||||
// 2013-05-05 - fix issue with writing bit values to words (Sasquatch/Farzanegan)
|
||||
// 2012-06-09 - fix major issue with reading > 32 bytes at a time with Arduino Wire
|
||||
// - add compiler warnings when using outdated or IDE or limited I2Cdev implementation
|
||||
// 2011-11-01 - fix write*Bits mask calculation (thanks sasquatch @ Arduino forums)
|
||||
// 2011-10-03 - added automatic Arduino version detection for ease of use
|
||||
// 2011-10-02 - added Gene Knight's NBWire TwoWire class implementation with small modifications
|
||||
// 2011-08-31 - added support for Arduino 1.0 Wire library (methods are different from 0.x)
|
||||
// 2011-08-03 - added optional timeout parameter to read* methods to easily change from default
|
||||
// 2011-08-02 - added support for 16-bit registers
|
||||
// - fixed incorrect Doxygen comments on some methods
|
||||
// - added timeout value for read operations (thanks mem @ Arduino forums)
|
||||
// 2011-07-30 - changed read/write function structures to return success or byte counts
|
||||
// - made all methods static for multi-device memory savings
|
||||
// 2011-07-28 - initial release

// 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:
|
||||
// 2013-05-08 - added seamless Fastwire support
|
||||
// - added note about gyro calibration
|
||||
// 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
