LcdDisplay is a simple Elixir library that allows you to control a Liquid-crystal display (LCD) like Hitachi HD44780.

See documentation and example apps for more information.

Installation

You can install LcdDisplay by adding lcd_display to your list of dependencies in mix.exs:

def deps do

  [

    {:lcd_display, "0.0.12"}

  ]

end

Examples

As an example, if you want to control a Hitachi HD44780 type display through I²C, you can use LcdDisplay.HD44780.I2C module as a display driver.

# Start the LCD driver and get a PID.

pid =

  LcdDisplay.start_display(

    LcdDisplay.HD44780.I2C,      # A display driver module

    %{display_name: "display 1"} # A config map

  )



# Run a command.

LcdDisplay.execute(pid, {:print, "Hello world"})

LcdDisplay.execute(pid, :clear)
