/*********************************************************************
SSD1306 I2C Library for Raspberry Pi.
Based on Adafruit SSD1306 Arduino library. Some functions came from Adafruit GFX lib.
Modified by Ilia Penev
Tested on Raspberry Pi 2 with 0.96 Yellow/Blue OLED
*********************************************************************/
/*********************************************************************
This is a library for our Monochrome OLEDs based on SSD1306 drivers
Pick one up today in the adafruit shop!
------> http://www.adafruit.com/category/63_98
These displays use SPI to communicate, 4 or 5 pins are required to
interface
Adafruit invests time and resources providing this open source code,
please support Adafruit and open-source hardware by purchasing
products from Adafruit!
