        This library is compatible with standard Character LCDs such as:
        * `Adafruit Standard LCD 16x2 <https://www.adafruit.com/product/181>`_
        * `Adafruit RGB backlight negative LCD 16x2 <https://www.adafruit.com/product/399>`_
        * `Adafruit RGB backlight negative LCD 20x4 <https://www.adafruit.com/product/498>`_
        
        Installing from PyPI
        --------------------
        
        On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
        PyPI <https://pypi.org/project/adafruit-circuitpython-charlcd/>`_. To install for current user:
        
        .. code-block:: shell
        
            pip3 install adafruit-circuitpython-charlcd
        
        To install system-wide (this may be required in some cases):
        
        .. code-block:: shell
        
            sudo pip3 install adafruit-circuitpython-charlcd
        
        To install in a virtual environment in your current project:
        
        .. code-block:: shell
        
            mkdir project-name && cd project-name
            python3 -m venv .env
            source .env/bin/activate
            pip3 install adafruit-circuitpython-charlcd
        
        Dependencies
        =============
        This driver depends on:
        
        * `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
        * `Adafruit CircuitPython BusDevice <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
        * `Adafruit CircuitPython MCP230xx <https://github.com/adafruit/Adafruit_CircuitPython_MCP230xx>`_
        * `Adafruit CircuitPython 74HC595 <https://github.com/adafruit/Adafruit_CircuitPython_74HC595>`_
        
        I2C & SPI displays also depend on:
        
        * `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
        
        Please ensure all dependencies are available on the CircuitPython filesystem.
        This is easily achieved by downloading
        `the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.
        
        Usage Example
        =============
        
        The ``Character_LCD`` class interfaces a predefined Character LCD display with CircuitPython.
        
        .. code-block:: python
        
            import board
            import digitalio
            import adafruit_character_lcd.character_lcd as character_lcd
        
        You must define the data pins (``RS``, ``EN``, ``D4``, ``D5``, ``D6``, ``D7``) in your code before using the ``Character_LCD`` class.
        If you want to have on/off ``backlight`` functionality, you can also define your backlight as ``lcd_backlight``. Otherwise, the backlight
        will always remain on. The following is an example setup.
        
        .. code-block:: python
        
            lcd_rs = digitalio.DigitalInOut(board.D7)
            lcd_en = digitalio.DigitalInOut(board.D8)
            lcd_d7 = digitalio.DigitalInOut(board.D12)
            lcd_d6 = digitalio.DigitalInOut(board.D11)
            lcd_d5 = digitalio.DigitalInOut(board.D10)
            lcd_d4 = digitalio.DigitalInOut(board.D9)
            lcd_backlight = digitalio.DigitalInOut(board.D13)
        
        You must also define the size of the CharLCD by specifying its ``lcd_columns`` and ``lcd_rows``:
        
        .. code-block:: python
        
            lcd_columns = 16
            lcd_rows = 2
        
        After you have set up your LCD, we can make the device by calling it
        
        .. code-block:: python
        
            lcd = character_lcd.Character_LCD_Mono(lcd_rs, lcd_en, lcd_d4, lcd_d5, lcd_d6, lcd_d7, lcd_columns, lcd_rows, lcd_backlight)
        
        
        To verify that your pins are correct, print a hello message to the CharLCD:
        
        .. code-block:: python
        
            lcd.message = "Hello\nCircuitPython"
        
        
        Custom character example with ``create_char()`` is provided within /examples/
