/**************************************************************************
 Manejo de una pantalla monocromática OLED basada con driver SSD1306

 Pick one up today in the adafruit shop!
 ------> http://www.adafruit.com/category/63_98

 This example is for a 128x64 pixel display using I2C to communicate
 3 pins are required to interface (two I2C and one reset).
