  [LcdDisplay](https://github.com/mnishiguchi/lcd_display) is a simple

  [Elixir](https://elixir-lang.org/) library that allows you to control an

  [Liquid-crystal display (LCD)](https://en.wikipedia.org/wiki/Liquid-crystal_display) like

  [Hitachi HD44780](https://en.wikipedia.org/wiki/Hitachi_HD44780_LCD_controller).



  ## Examples



  As an example, if you want to control a Hitachi HD44780 type display through

  [I²C](https://en.wikipedia.org/wiki/I%C2%B2C), you can use `LcdDisplay.HD44780.I2C` module as a

  display driver.



      alias LcdDisplay.HD44780



      # Start the LCD driver and get the initial display state.

      {:ok, display} = HD44780.I2C.start()



      # Run a command and the display state will be updated.

      {:ok, display} = HD44780.I2C.execute(display, {:print, "Hello world"})

      {:ok, display} = HD44780.I2C.execute(display, :clear)
