    00013 // This file implements a basic liquid crystal library that comes as standard
    00014 // in the Arduino SDK but using the extension board BV4218/BV4208 from ByVac.
    00015 //
    00016 // @brief
    00017 // This is a basic implementation of the LiquidCrystal library of the
    00018 // Arduino SDK. The original library has been reworked in such a way that
    00019 // this class implements the all methods to command an LCD based
    00020 // on the Hitachi HD44780 and compatible chipsets using I2C extension
    00021 // backpack BV4218 from ByVac.
    00022 //
    00023 // The functionality provided by this class and its base class is identical
    00024 // to the original functionality of the Arduino LiquidCrystal library.
