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.

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)
