[request] I2C OLED display example

Summary

Hello,

I would use I2C OLED display example to print pairing QRcode. Could you add an example?

Regards

I managed to run a demo code with an I2C OLED screen : SSD1306_128X64:

#include <Arduino.h>
#include <U8g2lib.h>
#include <Wire.h>
#include "smiley_face.h" 

// QWIIC connector
#define SDA 20
#define SCL 19

// SW_I2C	Software emulated I2C/TWI
U8G2_SSD1306_128X64_NONAME_1_SW_I2C u8g2(U8G2_R0, SCL, SDA, U8X8_PIN_NONE);

int xx = 20; 
int yy = 10; 

void setup() {
    Serial.begin(115200); // Initialize the serial communication at 115200 baud rate
    u8g2.begin();
}

void loop() {
    smeil_display();
    delay(500); 
}

void smeil_display() {
    const unsigned char* smileImages[] = {
        semil1, semil2, semil3, semil4, semil5,
        semil6, semil7, semil8, semil9, semil10,
        semil11, semil12, semil13, semil14, semil15,
        semil16, semil17, semil18, semil19, semil20,
        semil21, semil22, semil23, semil24, semil25,
        semil26, semil27
    };

    int delays[] = {
        40, 50, 40, 40, 40,
        40, 40, 50, 40, 40,
        40, 40, 40, 50, 40,
        40, 50, 40, 40, 50,
        40, 50, 40, 40, 50,
        50, 50, 40, 50
    };

    for (int i = 0; i < sizeof(smileImages) / sizeof(smileImages[0]); i++) {
        u8g2.firstPage();
        do {
            u8g2.drawXBMP(xx, yy, 48, 48, smileImages[i]); 
        } while (u8g2.nextPage());
        delay(delays[i]); 
    }
}
