For all of the different kinds of small OLED monochrome displays, you'll need to install the Arduino libraries. The code we have is for any kind of Arduino, if you're using a different microcontroller, the code is pretty simple to adapt, the interface we use is basic bit-twiddling SPI.
To download the Arduino library, visit the Adafruit SSD1306 library repository on GitHub . Click the DOWNLOAD button near the upper left, extract the archive and then rename the uncompressed folder to Adafruit_SSD1306. Confirm that this folder contains the files Adafruit_SSD1306.cpp and Adafruit_SSD1306.h and the examples folder.
Place the Adafruit_SSD1306 folder inside your Arduino /libraries folder. You may need to create this folder if it does not yet exist. In Windows, this would be (home folder)\My Documents\Arduino\libraries and for Mac or Linux is (home folder)/Documents/Arduino/libraries. We also have a tutorial on library installation.
After installing the Adafruit_SSD1306 and Adafruit_GFX library, restart the Arduino IDE. You should now be able to access the sample code by navigating through menus in this order: File→Sketchbook→Libraries→Adafruit_SSD1306→SSD1306...
After you've finished wiring the display as indicated on the following pages, load the example sketch to demonstrate the capabilities of the library and display.
The OLED SSD1306 driver is based on the Adafruit GFX library which provides all the underlying graphics functions such as drawing pixels, lines, circles, etc. For more details about what you can do with the OLED check out the GFX library tutorial
