How do you talk to a small character LCD screen using nerves?

Tags: #<Tag:0x00007f114722b280>


I have been trying to connect a small LCD display to a raspberry pi, but I do not get how to make real text appear on the screen. Can somebody please tell me how I can do this? Thanks in advance! By the way if you do not know what I mean by a small LCD display I mean this:


According to Adafruit: Drive a 16x2 LCD with the Raspberry Pi there are at least three ways (GPIO pins, I2C, and UART) to connect a HD44780 to the board.

  • That may explain why there isn’t a library yet.
  • For further help (from somebody else) you’ll likely have to identify the hardware interface that you have used.

It seems that elixir_ale is useful for interfacing via GPIO, I2C and SPI.
