// I2Cdev library collection - Main I2C device class
// Abstracts bit and byte I2C R/W functions into a convenient class
// 6/9/2012 by Jeff Rowberg <jeff@rowberg.net>
//
// Changelog:
// 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// - add compiler warnings when using outdated or IDE or limited I2Cdev implementation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

// I2Cdev library collection - Main I2C device class header file
// Abstracts bit and byte I2C R/W functions into a convenient class
// 6/9/2012 by Jeff Rowberg <jeff@rowberg.net>
//
// Changelog:
// 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// - add compiler warnings when using outdated or IDE or limited I2Cdev implementation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

// DMP FIFO update rate: 0x09 drops the FIFO rate down to 20 Hz. 0x07 is 25 Hz,
// 0x01 is 100Hz. Going faster than 100Hz (0x00=200Hz) tends to result in very
// noisy data. DMP output frequency is calculated easily using this equation:
// (200Hz / (1 + value))
// It is important to make sure the host processor can keep up with reading and
// processing the FIFO output at the desired rate. Handling FIFO overflow
// cleanly is also a good idea. thanks to Noah Zerkin for piecing this stuff
// together!
