Yay, another nice port to have..
Adafruit lib is better for number of reasons..at least for me 😁
– notes: check esp8266 i2c speed setting in your version of the Adafruit library
if there is no setting in your version, like in my old ones, insert these lines into Adafruit_SSD1306.cpp file, into the fuction which does display init ->
void Adafruit_SSD1306::display(void), pick some line above the „// I2C“ comment, or if u dont know..just leave it or google it..
#ifdef ESP8266 // set speed for ESP devices
