Here is a quick overview showing a Crystalfontz CFAL5016A-Y 50×16 Graphic OLED Module in SPI mode connected to an Arduino Uno R3.

Arduino With Crystalfontz SPI Graphic OLED

The display is connected using 3-wire SPI mode which uses 10-bit transfers. The software demonstrates bit-banged software 10-bit SPI.

Video Demonstration

Please note: There is banding on the OLED, which is an artifact between the OLED refresh rate and the video camera sample rate. The display looks rock solid to the naked eye.
