Vi prego qualcuno che mi aiuti, sono 3 ore che cerco su internet ed ormai i neuroni mi sono finiti, mi compare l'errore:
Opzioni di compilazione cambiate, ricompilo tutto LDC_16x2_ic2:6: error: 'POSITIVE' was not declared in this scope LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
[u] [1] exit status 1 'POSITIVE' was not declared in this scope
#include <Wire.h>
#include <LiquidCrystal_I2C.h> // Using version 1.2.1
// The LCD constructor - address shown is 0x27 - may or may not be correct for yours
// Also based on YWRobot LCM1602 IIC V1
LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
void setup()
{
lcd.begin(16,2); // sixteen characters across - 2 lines
lcd.backlight();
// first character - 1st line
lcd.setCursor(0,0);
lcd.print("Hello World!");
// 8th character - 2nd line
lcd.setCursor(8,1);
lcd.print("-------");
}
void loop()
{
}
