I’m brand new to Raspberry Pi, having just got a 3 last week. I’ve been playing with a Display-O-Tron HAT and I thought it would be useful to be able to enter text on it. I know there’s already a menu plugin for that in the sample code, which uses a rotational system and has a max of 16 characters.
I wrote a new text-entry system that allows any length of input, and is more like the cursor-based input systems on video games consoles etc. Maybe you’ll find it useful for something.
Full info, photo of it in action, and of course the code is all here: https://github.com/mattgemmell/DOT-MGTextEntry
