Counter module Basics

[NaveenChengappa-IFX]

Summary

• Implemented basic Counter module.
• It has the constructor, Init(), Deinit() and the value() methods in this PR.
• Basic boundary conditions and parameter validations implemented.

Testing

• HIL testing carried out.
• Local testing by coupling a PWM output to count the number of rising edges.

Trade-offs and Alternatives

• Only one pin is exposed on the board (P11_1) and that was used for testing.
• Counter triggered IRQ implementation, Cycles(), init() parameters and documentation is handled in PR Counter Init() parameters, cycles() and IRQ() #163.

Generative AI

I did not use generative AI tools when creating this PR.

Looks Great! 🔥

Just what we discussed offline on timer, counter instance affect on each other can be verified through a test,. Rest looks good to me :)

Very good progress 👍

The docs are missing. I guess that will come in another PR.
Mostly there explaining only the differences with the general API.

And for the rest, whatever features and modes are missing once decided.

As a general topic, we should reuse the existing libs and approaches when possible, this will make the machine classes more harmonized, therefore easier to maintain in the long run.
In many cases, is not only a OCD whim, but a way to ensure that this class works together with the rest properly.
Otherwise, these classes functionality won't properly out of their unit isolation in which we develop them.
