// 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// - add compiler warnings when using outdated or IDE or limited I2Cdev implementation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
