[cmaglie]

could you post some more information? Like the board you're using, a copy of the sketch, the version of the IDE....

[bhavindholu87]

Version - 1.8.10
I'm using the arduino UNO
I'm work on i2c lcd display 16x2

[cmaglie]

• which operating system?
• set "Verbose compile" from the preferences and copy&paste the full output.
• copy&paste also the sketch

[bhavindholu87]

this code in coming error:

#include <LiquidCrystal_I2C.h>

#include "Wire.h" // For I2C
#include "LCD.h" // For LCD
#include "LiquidCrystal_I2C.h" // Added library*
//Set the pins on the I2C chip used for LCD connections
//ADDR,EN,R/W,RS,D4,D5,D6,D7
LiquidCrystal_I2C lcd(0x27,2,1,0,4,5,6,7); // 0x27 is the default I2C bus address of the backpack-see article
void setup()
{
   // Set off LCD module
   lcd.begin (16,2); // 16 x 2 LCD module
   lcd.setBacklightPin(3,POSITIVE); // BL, BL_POL
   lcd.setBacklight(HIGH);
  
}
void loop()
{
   lcd.setCursor(5,0);
   lcd.print("Marwadi");}

[cmaglie]

There is something going on in your particular installation but, to understand what the problem is, I need you to enable the "verbose compile" by flagging the check box in the preferences window as in the following image:

After doing so, please, verify again the sketch and copy the output here. The output should be much longer and detailed.

@bhavindholu87 did you solve the issue? may you give the requested information?
