/************************************************************************** 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).
