SSD1306 OLED display driver for Raspberry Pi Pico: How's the code quality?

Hi guys,

I started tinkering with Swift Embedded on my Pi and I wanted to have a little bit of graphical representation.

That's why (and sorry to say that) I spent my monthly GH Copilot quota on creating a "driver" or "manager" or "controller" for a SSD1306 display (0.96"). It seems that these kind of displays are quite Elegoo wiki common and I was able to source than for just a few bucks.

But, as I said, most of the Code is created using AI. And I do not fully trust it, if I should use the code as it is.

This is a pity because it works but I do not really like things a cannot validate by myself. That's why I would love to ask the amazing community if anyone of you could have a look at the code in the following PR.

If there is a package I should use without using my newbie code, please let me know. I was not really able to find a "premade" package for a driver.

Thanks for all you effort in helping me getting settled!

Sorry for my miswriting. I meant more that if I read, I understand the code but not if this is the way how it should be done.

For example would be such a Review finding show a bad implementation or is it a false friend?

You are absolutely right that I should phrase it better, sorry for creating the point of view that I wanted to shift my work to you. I just want to be sure that if anybody reads the code, it is an okay-ish way of doing it and not destroying the hardware.

Thanks for the feedback!
