+/*********************************************************************
+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 128x64 size display using I2C to communicate
+3 pins are required to interface (2 I2C and one reset)
+
+Adafruit invests time and resources providing this open source code,
