Get lcd2usb firmware version::

    >>> lcd.version
    (1, 9)

Write something on the screen::

    >>> lcd.write('Hello, LCD2USB!')

Clean screen and wirte some on the 2nd row::

    >>> lcd.clear()
    >>> lcd.goto(0, 1)
    >>> lcd.write('Flying with PYTHON')

Or simpler::

    >>> lcd.write('Flying with PYTHON', 0, 1)

Define a custom smile symbol and display it on the center of first row
(on a 4x20 display)::

    >>> from lcd2usb import SMILE_SYMBOL
    >>> lcd.define_char(0, SMILE_SYMBOL)
