It’s generally quite easy to use these over I2C without a driver. You can crib the sequence of initialization commands from the example code supplied by the manufacturer (or loads of examples on GitHub), and then the commands to draw to the screen are pretty straightforward. The chip has its own display RAM, so you don’t need to worry about redrawing every time the display refreshes or anything as low-level as that.

That's what I ended up doing since I was using a CH32V305. It is amusing how many ways you can initialize the display into weird modes like "upside down" or "thinks there's 64 vertical pixels when there's only 32".

I wish they were available in slightly larger models-- even if it's only 128x64, there are plenty of spots where a 5-8cm display would be more legible than the 3cm or less ones that are common,
