6 years ago It looks like the code was written for the 3.x.x versions of the esp8266-oled-ssd1306 library. Some small modifications are needed for compatibility with the 4.x.x versions of that library: https://github.com/ThingPulse/esp8266-oled-ssd1306/blob/master/UPGRADE-4.0.md
When i try to compile the example i get these errors:
