/************************************************************************** 

 This is an example for our Monochrome OLEDs based on SSD1306 drivers 

 

 Pick one up today in the adafruit shop! 

 ------> http://www.adafruit.com/category/63_98 

 

 This example is for a 128x32 pixel display using I2C to communicate 

 3 pins are required to interface (two I2C and one reset).
