how to use it with an Oled Display

[herbkonik]

Hi,
because i'm sometimes low with Analog Input Pins (Arduino Nano), i try to use pin 11 und 12 for output at an Oled Display, but get no solution...
Is there any example sketch for display output ? And a hint which Oled lib will work ?
I'm a bit lost atm... The whole sketch works if i use Pin A4 / A5 and wire with Addafruit Oled libs.
