This is documentation for Adafruit's generic library for grayscale OLED displays: http://www.adafruit.com/category/63_98
These displays use I2C or SPI to communicate. I2C requires 2 pins (SCL+SDA) and optionally a RESET pin. SPI requires 4 pins (MOSI, SCK, select, data/command) and optionally a reset pin. Hardware SPI or 'bitbang' software SPI are both supported.
