Display-O-Tron text-entry plugin (here's my code)

Discussion Projects

Hi there,

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

This is really nice, great job!

You could massively increase the density of the “selection” area by either blinking the current character (simple) or defining an inverted custom character (tougher) for the active item. Then you’d save all that whitespace - however I quite like the style of it. :-)
