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 or I2C

Install Arduino Libraries

Using these OLEDs with Arduino sketches requires that two libraries be installed: Adafruit_SSD1306, which handles the low-level communication with the hardware, and Adafruit_GFX, which builds atop this to add graphics functions like lines, circles and text.

In recent versions of the Arduino IDE software (1.6.2 and later), this is most easily done through the Arduino Library Manager.

Open up the Arduino library manager:

Search for the Adafruit SSD1306 library and install it

Search for the Adafruit GFX library and install it

We also have a great tutorial on Arduino library installation here:

Run Demo!

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

Create Bitmaps

You can create bitmaps to display easily with the LCD assistant software. First make your image using any kind of graphics software such as photoshop or Paint and save as a Monochrome Bitmap (bmp)

Select the following options (You might also want to try Horizontal if Vertical is not coming out right)

and import your monochrome bitmap image. Save the output to a cpp file

You can use the output directly with our example code
