[arduino code examples for G1]-06 Print TEXT on SSD1306 OLED displayer

Code:
/*

 * Made by KinCony IoT: https://www.kincony.com

 * 

 * This Arduino program demonstrates how to display text on an SSD1306 128x64 OLED display using the U8g2 library.

 * The program draws two lines of text on the display:

 * - The first line is "KINCONY" in a larger font.

 * - The second line is "www.kincony.com" in a smaller font.

 * 

 * The display is connected via I2C (software implementation) with:

 * - SCL (clock) on pin IO11

 * - SDA (data) on pin IO12

 * 

 * The display's I2C address is set to 0x3C.

#include <U8g2lib.h>  // Include the U8g2 library for controlling the OLED display

#include <Wire.h>     // Include the Wire library for I2C communication



// Initialize the display using the software I2C method (SCL = IO11, SDA = IO12)

U8G2_SSD1306_128X64_NONAME_F_SW_I2C u8g2(U8G2_R0,  11, 12, U8X8_PIN_NONE);  // Screen rotation: U8G2_R0



// Function to display page 1 content

void page1() {

  // Set font size 18 for the larger "KINCONY" text

  u8g2.setFont(u8g2_font_timR18_tf);  // Use the Times Roman font, size 18

  u8g2.setFontPosTop();               // Set the text position at the top of the display

  u8g2.setCursor(5, 0);               // Position the cursor at coordinates (5, 0)

  u8g2.print("KINCONY");              // Display the text "KINCONY" on the screen



  // Set font size 12 for the smaller "www.kincony.com" text

  u8g2.setFont(u8g2_font_timR12_tf);  // Use the Times Roman font, size 12

  u8g2.setCursor(0, 40);              // Position the cursor at coordinates (0, 40)

  u8g2.print("www.kincony.com");      // Display the text "www.kincony.com"

}



// Setup function, runs once when the program starts

void setup() {

  // Set the I2C address for the display to 0x3C

  u8g2.setI2CAddress(0x3C*2);  // I2C address shift for 8-bit format

  

  // Initialize the display

  u8g2.begin();

  

  // Enable UTF-8 character printing for the display

  u8g2.enableUTF8Print();  // Allow UTF-8 encoded text to be printed

}



// Main loop function, continuously runs after setup()

void loop() {

  // Begin the display drawing process

  u8g2.firstPage();  // Prepare the first page for drawing

  do {

    // Call the page1() function to draw content on the display

    page1();

  } while (u8g2.nextPage());  // Continue to the next page until all pages are drawn
