/*********************************************************************
*
** Modified Adafruit Library to work with OLED SSD1306_128_64 with SPI communication only **
* By: Jordi Segura
*
This is a library for 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,
