Wyświetlacz OLED 0.91 inch 128 x 32 px

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