Code 2

Seeeduino-nano + port I2c + 16x2 LCD White on Blue
cette combinaison fonctionne avec le code suivant :

#include <Wire.h>
#include "rgb_lcd.h"

rgb_lcd lcd;

/*
const int colorR = 255;
const int colorG = 0;
const int colorB = 0;
*/

void setup() 
{
    // set up the LCD's number of columns and rows:
    lcd.begin(16, 2);
    
    //lcd.setRGB(colorR, colorG, colorB);
    
    // Print a message to the LCD.
    lcd.print("hello, world!");

    delay(1000);
}

void loop() 
{
    // set the cursor to column 0, line 1
    // (note: line 1 is the second row, since counting begins with 0):
    lcd.setCursor(0, 1);
    // print the number of seconds since reset:
    lcd.print(millis()/1000);

    delay(100);
}

#include <LiquidCrystal_I2C.h>

// I2C address of the LCD (check your specific LCD if it's different)
#define LCD_I2C_ADDRESS 0x01

// Define the LCD as an object
LiquidCrystal_I2C lcd(LCD_I2C_ADDRESS, 16, 2); // 16 columns, 2 rows

void setup() {
  // Initialize the LCD
  lcd.init();
  // Turn on the backlight
  // lcd.backlight();
  // Optional: Set custom characters if needed
  // lcd.createChar(0, custom_char_data);
  // You can use the custom_char_data array from a tool like LCD-Character-Creator (https://maxpromer.github.io/LCD-Character-Creator/)
}
void loop() {
  // Clear the LCD (optional)
  lcd.clear();
  // Set the cursor to the desired position (column, row)
  // 0,0 is the top-left corner
  lcd.setCursor(0, 0); 
  // Print text to the LCD
  lcd.print("Hello, World!");
  // Optionally, delay for a period
  delay(2000);
