Getting the OLED work is a bit tricky, especially for beginners i think. The BoobieTrap here is that you have set Pin16 (OLED_RST) to High or you will see nothing on your display.
Took me a few hours to trick this out :)

just add following lines to your setup loop

pinMode(16,OUTPUT);
digitalWrite(16, LOW); // set GPIO16 low to reset OLED
delay(50);
digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high

and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)

i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys
both work.

Display size is 128x64
