Then we will display the analog voltage on OLED Screen. In this example we will feed the input value of analog voltage from Potentiometer to analog Pin GP28 of Raspberry Pi Pico. To learn more about the I2C Pins use & Applications you can use our Raspberry Pi Pico I2C Guide. You can use any of the pair of I2C Pins for interfacing applications. The Raspberry Pi Pico Board has two pair of I2C Pins. Now let us learn how we can interface SSD1306 OLED Display with Raspberry Pi Pico. Interfacing SSD1306 OLED Display with Raspberry Pi Pico OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays. In contrast to LCD technology, OLED does not require a backlight. OLED (Organic Light-Emitting Diode) is a self-light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. The package includes a display board, a display,4 pin male header pre-soldered to board. You can interface this display module with any microcontroller using SPI/IIC protocols. This SSD1306 is a 0.96/1.3 inch blue OLED display module. The OLED displays are one of the most attractive displays available for a microcontroller because of their viewing angle and pixel density. You cany purchase the required components for this tutorial from the following Amazon link.
But before that we recommend you to go through Raspberry Pi Pico Getting Started Guide and also about the way of using the I2C Pin. We will display the Analog value voltage from the Potentiometer on OLED Display. After writing the driver code, we can write anything and display it on OLED Display. The MicroPython IDE requires the SSD1306 Driver Code. We will use Micropython code here to used OLED Display with Pico Board. You can use any of the I2C Pins of Raspberry Pi Pico for Interfacing SSD1306 OLED Display. The Raspberry Pi Pico that comes with an RP2040 microcontroller has two Pairs of I2C Pins. But in this tutorial, we will use the 0.96″ I2C OLED Display as it requires only 2 wires for Interfacing. The SSD1306 OLED display is available in both I2C & SPI Modules. It has a good view angle and pixel density which makes it reliable for displaying small level graphics. The OLED displays are one of the most attractive displays available for a microcontroller. In this tutorial we will learn about the Interfacing of SSD1306 OLED Display with Raspberry Pi Pico. Interfacing SSD1306 OLED Display with Raspberry Pi Pico.
