Unfortunately I don´t know of that language, so I checked the link to the library and the code provided there, but it tells me there's an invalid connection in the arduino IDE, I think this is caused by the enabler having the same name as the library. Can someone help me confirm this? And if you do, Can you tell me how to fix it?
// Set the LCD address to 0x27 for a 16 chars and 2 line display
// Arduino UNO => PIN 4 = SCL, PIN 5 = SDA
// NodeMCU Dev Kit => D1 = SCL, D2 = SDA
#define SCL D3
#define SDA D4
LiquidCrystal_I2C lcd(0x27, 16, 2);
// initialize the LCD
// Turn on the blacklight and print a message.
lcd.print("Hello LCD Line 1");
lcd.print("Hello LCD Line 2");
lcd.print("Hello LCD Line 3");
lcd.print("Hello LCD Line 4");
// Do nothing here...
