Arduino Library & Examples

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.

You will need to do the same for the Adafurit_GFX library available here

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

The library cannot determine the screen size via software. You have to specify it in the header file. Go into the library folder and open the file Adafruit_SSD1306.h. Toward the top you'll see a section of comments that tell how how to edit the file for different kinds of display.

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
