I wrote a small SSD1306 library for AVR, with a framebuffer.
It even features a small simulator to let you have a preview of what it’ll look like on the OLED screen without having to upload again and again code to your development board.
The library is released under a very permissive license, to allow people to integrate it without any constraints.
Available on Github.
