The full menu navigation to this sketch is File → Examples → Adafruit SSD1306 → ssd1306_128x32_12c Run the Example OLED SketchĪfter opening the ssd1306_128x32_12c example sketch, load it to the Arduino board with the OLED wired, as already explained.

Open the ssd1306_128x32_12c example sketch from the above menu. Under File → Examples, scroll down to find the section called Examples from Custom Libraries to find the Adafruit SSD1306 examples. These example sketches are found under File → Examples → Adafruit SSD1306 from the top menu of the Arduino IDE. Open OLED Display Arduino Example SketchĪfter installing the two libraries, as described above, new example sketches are found in the Arduino IDE. Hover the mouse cursor over the Adafruit GFX Library item in the Library Manager dialog box. With the Library Manager dialog box still open from the above step, type GFX in the search field.

Wire library arduino uno install#

Leave the Library Manager dialog box open to install the GFX library next. Hover the mouse cursor over the Adafruit SSD1306 item, and then click the Install button that appears.

Wire library arduino uno driver#

Select the SSD1306 Driver in the Arduino IDE In the Library Manager dialog box, type SSD1306 in the search field, as shown in the image below. This opens the Library Manager dialog box. Use the top menu bar to select Tools → Manage Libraries. Both these libraries can be installed from within the Arduino IDE. The GFX library provides graphics functions for displaying text, drawing lines and circles, etc. The SSD1306 driver library is used to initialize the display and provide low level display functions. Two Arduino libraries must be installed in the Arduino IDE to start using the display. Pin connections for wiring an Arduino MEGA 2560 to the OLED display are as follows.Īrduino 128 x 32 OLED I☬ Libraries for SSD1306 and Graphics Functions

How to Connect the Geekcreit 128 x 32 0.96 Inch OLED I2C Display to Arduino – Wiring Diagram Arduino MEGA 2560 0.91 Inch OLED Wiring Pin connections are as follows for wiring the OLED display to an Arduino Uno. The image below shows how to connect the Geekcreit 0.91 inch OLED I2C display to Arduino. Geekcreit 128 x 32 0.91 Inch OLED Display I2C/TWI Pinout Arduino Uno to 0.91 Inch 128 x 32 OLED Wiring Don't blow up your display!Īlso make sure that your display is 5V compatible as this one is. Some modules have GND and VCC swapped around. If the pins are swapped, make sure to change the connections to the Arduino – OLED VCC connects to 5V on the Arduino, OLED GND to GND on the Arduino.Ĭaution! Make sure that you connect the power pins correctly. Check your display to make sure that it is the same as the image below. The first and most important thing to note is that some of the displays may have the GND and VCC power pins swapped around. How to Connect the Geekcreit 0.91 Inch I2C OLED Display to Arduino Some OLED displays are rated to operate from 3.3V only. If you have a similar display, make sure that it is rated to operate at 5V. On the SOT23 package is the marking 662K which denotes a 5V in to 3.3V out voltage regulator.īecause of the regulator, the display can be connected to a 5V Arduino, such as an Arduino Uno or Arduino MEGA 2560. This regulator is a XC6206 series voltage regulator in a SOT-23 package. The OLED display shown in the above image connected to an Arduino Uno has a regulator on the bottom layer of the circuit board. 128 x 32 0.91 Inch OLED Connected to an Arduino Uno About the 128 x 32 0.91 Inch OLED Display

After installing the libraries, an example sketch can be run to test if the display is working. Libraries are installed in the Arduino IDE to make using the OLED display very quick and easy. This interface is sometimes called TWI (Two Wire Interface). The data connection is I2C (I☬, IIC or Inter-Integrated Circuit). The display connects to Arduino using only four wires – two for power, one for clock and one for data, making the wiring very simple. Libraries are then installed and some example programs run which show how to use the display in an Arduino sketch. In this tutorial a 0.91 inch monochrome OLED display from Geekcreit is connected or interfaced to an Arduino.
