New repository needed for reusable device drivers and components

[mores]

I feel like pi4j needs a new top level repository, pi4j-extensions. This repository would contain reusable device drivers and components. Basically promoting much of what is already written in pi4j-example-devices AND pi4j-example-components.

It would define interfaces like:
DualState ( on, off )
TriState ( on, off, held )
ColorDisplay
MonoDisplay
LinearPosition
Pixel

Components:
PixelColor used as input to set color of Pixel or Displays
SimpleButton implements TriState
SimpleSwitch implements DualState
ST7789 implements ColorDisplay
Adafruit5880 implements LinearPosition, TriState, Pixel

Both pi4j-example-devices AND pi4j-example-components would still exist. These projects now depend on pi4j-extensions. These projects would still define the logging framework, assets, launchers and executables.

You are right, there is a bit of "split" between these two repositories, as one originates from the FHNW university based on the CrowPi, and the other one is the efforts done by @taartspi to provide example code for all types of devices... I love your idea, but I'm afraid this would require a lot of work and not sure if someone is available to pick this up.

I will start to throw something together. My day job keeps me plenty busy, but when I have something to share I will post an update here.

That would be really awesome!

wouldn't it even be better if such a project would eventually combine all examples from both pi4j-example-devices and pi4j-example-components, so we can archive those and have one big single example project?

I want to underscore that I am looking for a reusable library that anyone can use, not a standalone executable.
Hopefully this picture will help clarify my intentions:

There was such a library in Pi4J in V1, but it became difficult to maintain and test. That's why it's no longer part of the "core" V2 library. But as a separate project, it could indeed be logical.
