Thanks for this great module!
I couldn't find in the documentation what pins need to be connected for the SSD1306 in 128X64 in I2C mode. I am able to get the display to work fine with the adafruit library but doing a simple hello world with this library gives me nothing.
I'm using it with an Arduino Mega and I have SDA and SCL connected to 20 and 21 and I have tried with the reset line disconnected and connected to pin 4.
Any suggestions?
