// @file LiquidCrystal_I2C_ByVac.c
// This file implements a basic liquid crystal library that comes as standard
// in the Arduino SDK but using the extension board BV4218/BV4208 from ByVac.
//
// @brief
// This is a basic implementation of the LiquidCrystal library of the
// Arduino SDK. The original library has been reworked in such a way that
// this class implements the all methods to command an LCD based
// on the Hitachi HD44780 and compatible chipsets using I2C extension
// backpack BV4218 from ByVac.
//
// The functionality provided by this class and its base class is identical
// to the original functionality of the Arduino LiquidCrystal library.
