A fork of the ssd1206 library for Micropython I have found, quite well written. This fork originally added the rotate180() method, which was absent. And then I started adding more features. I pushed a PR, but the project seems dormant.

This is being tested on an Elecfreaks Wukong 悟空 2040, donated by Elecfreaks, and an original Pico.

• rotate: Set this variable to True or False to rotate the display automatically. The library's show() function calls rotate180() when needed.
• rotate180(): self-explanatory I believe...
• drawOval(self, cX, cY, rX, rY): draws an oval centered on cX, cY. Radius X and Y determine the shape.
• drawCircle(self, cX, cY, radius): calls drawCircle with 2 identical radii.
• fillOval(self, cX, cY, radius): draws a filled disk centered on cX, cY, in white (1, default) or black (0). Radius X and Y determine the shape.
• fillCircle(self, cX, cY, radius): calls fillCircle with 2 identical radii.
• drawLines(self, lines, clr = 1): draws lines from an array lines[] of points. Needs a multiple of 4 ints.
• drawConnectedLines(self, lines, clr = 1): draws connected lines from an array lines[] of 4 points. Needs a multiple of 2 ints, minimum 4 in total. The end point of a line becomes the start point of the next line.

There is a floodFill() method, but it's not working well. I need to improve it.

I am using at the end of the current demo a Timer object to display an animation that runs on its own. I updated the demo GIF, see for yourself. The animation keeps running, although the program ended.
