I2C LCD display

[kegde]

I am experimenting with Rpi4B and Python to "gain experience". I have worked a lot with Arduino (years ago) and Rpi is new to me. If I feel more confident with Rpi en Phyton I am going to make a controller and measuring station for my aquariums.

At this moment I want to make a “Hello world prg” for an I2C LCD display. But I mainly find old posts on the Internet and the examples I tried have all failed. I use the following display

Crazy question maybe, but are these kinds of displays still being used at the moment, or are other output devices more common nowadays.
And can you refer me to a working example for my setup (Rpi4B, Python3, aforementioned LCD screen)?

Hi.

Assuming this is a standard 16x2 or 20x4 LCD using the Hitachi HD44780 or a clone of it then you might look at RPLCD it supports this type of display both using a direct parallel gpio connection and the I2c back packs.

You will just need to check your backpack is actually supported.
