Page 3: Overview
Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness! © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts Page 3 of 22... - Page 4 The driver chip, SSD1306 can communicate in multiple ways including I2C, SPI and 8-bit parallel. However, only the 128x64 display has all these interfaces available. For the 128x32 OLED, only SPI is available. Frankly, we prefer SPI since its the most flexible and uses a small number of I/O pins so our example code and wiring diagram will use that.

Page 5: Power Requirements
0.96" 128x64 OLED The older 0.96" 128x64 OLED is a little more complex to get running as it is not 5V compatible by default, so you have to provide it with 3.3V power. © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts Page 5 of 22... - Page 6 If you're not using the charge pump, connect this to a 7-9V DC power supply. For most users, we suggest connecting VDD and VBAT together to 3.3V and then leaving VCC unconnected. © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts Page 6 of 22...

Page 7: Arduino Library & Examples
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 (http://adafru.it/aPx) -
Page 8: Create Bitmaps
You can create bitmaps to display easily with the LCD assistant software (http://adafru.it/aPs). First make your image using any kind of graphics software such as photoshop or Paint and save as a Mo no chro me Bitmap (bmp) © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts Page 8 of 22 Industries... - Page 9 Select the following options (You might also want to try Ho rizo ntal if Vertical is not coming out right) and import your monochrome bitmap image. Save the output to a cpp file © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts Page 9 of 22...

Page 11: Wiring 128X64 Oleds
The nice thing about the 128x64 OLEDs is that they can be used with I2C (+ a reset line) or SPI. SPI is generally faster than I2C but uses more pins. It's also easier for some microcontrollers to use SPI. Anyways, you can use either one with this display Using with I2C © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts Page 11 of 22 Industries... -
Page 12: Using With Spi
The breakouts are ready for SPI by default, but if you used them for I2C at some point, you'll need to remove the solder jumpers. Use wick or a solder sucker to make sure both are clear! © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts... - Page 13 This matches the example code we have written. Once you get this working, you can try another set of pins.

First up, take a piece of 0.1" header 6 pins long. Plug the header long end down into a breadboard Place the OLED on top Solder the short pins into the OLED PCB. © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts Page 16 of 22 Industries... - Page 17 This matches the example code we have written. Once you get this working, you can change the RST pin. You cannot change the I2C pins, those are 'fixed' in hardware Finally you can run the File® ® Sketchbo o k® ® Libraries® ® Adafruit_SSD1306® ® SSD1306_128x32_i2c example © Adafruit http://learn.adafruit.com/monochrome-oled-breakouts Page 17 of 22 Industries...

Page 20: Downloads
Downloads Yo u can do wnlo ad o ur SSD1306 OLED display Arduino library fro m github (http: //adafru.it/aHq) which comes with example code. The library can print text, bitmaps, pixels, rectangles, circles and lines. It uses 1K of RAM since it needs to buffer the entire display but its very fast! The code is simple to adapt to any other microcontroller. -
