// I2Cdev library collection - Main I2C device class header file
// Abstracts bit and byte I2C R/W functions into a convenient class
// 2013-06-05 by Jeff Rowberg <jeff@rowberg.net>
//
// Changelog:
// 2020-01-20 - hardija : complete support for Teensy 3.x
// 2015-10-30 - simondlevy : support i2c_t3 for Teensy3.1
// 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// - add compiler warnings when using outdated or IDE or limited I2Cdev implementation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 Library hosted at http://www.i2cdevlib.com
//
// Changelog:
// 2012-04-01 - initial release
// 2015-11-08 - added TVoc and Status
