  Example-05_ScrollFlip.ino

  This demo shows the various display options - scrolling, flipping, invert.

  NOTE: Scrolling isn't supported on the Transparent OLED

  This library configures and draws graphics to OLED boards that use the
  SSD1306 display hardware. The library only supports I2C.

  SparkFun sells these at its website: www.sparkfun.com
