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 .venv
source .venv/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/
