Example: Using SSD1351 with Arduino UNO

Below is an example of how to connect and program the SSD1351 module with an Arduino UNO using the SPI interface.

Wiring Diagram

Arduino Code Example

#include <Adafruit_GFX.h>       // Include Adafruit GFX library for graphics
#include <Adafruit_SSD1351.h>   // Include Adafruit SSD1351 library for the display

// Define pin connections
#define OLED_CS   10  // Chip Select pin
#define OLED_DC   9   // Data/Command pin
#define OLED_RST  8   // Reset pin

// Create an instance of the SSD1351 display
Adafruit_SSD1351 display = Adafruit_SSD1351(128, 128, &SPI, OLED_CS, OLED_DC, OLED_RST);

void setup() {
  // Initialize the display
  display.begin();
  
  // Clear the display with a black background
  display.fillScreen(SSD1351_BLACK);
  
  // Display a message
  display.setTextColor(SSD1351_WHITE);
  display.setTextSize(1);
  display.setCursor(0, 0);
  display.println("Hello, SSD1351!");
}

void loop() {
  // Add your code here to update the display
}

Important Considerations and Best Practices

• Voltage Levels: Ensure the module is powered with the correct voltage (3.3V or 5V).
• SPI Speed: Use an appropriate SPI clock speed to avoid communication errors.
• Reset Pin: Always connect the RES pin to ensure proper initialization.
• Library Support: Use a compatible library like Adafruit SSD1351 for easier integration.
