I'm back from some two weeks in Mexico, so I can go back to playing with my Raspberry.

Got I2C communications to work and rendering to a SSD1306 with Scala Native.

I admit that I'm a bit confused about the coordinate system (and the way pixels are sent to the screen in vertical batches along the horizontal axis doesn't help), but it works, and I think if I play around with some initialization flags things should be more intuitive.

For now, I'm happy that it's working.
