TIMER0 Intrrupt not working

Projects Programming

Dear All

Following code for timer0 interrupt does not compile in the ARDUINO IDE

void setup() {
 
}

void loop() {
  

}

ISR (TIMER0_OVF_vect)  
{ 


Please advice 
}

That's because there's already an ISR on timer0 that is in the Arduino runtime for doing millis() and delay().

You can't have two ISR's on the same interrupt channel.

Can we able to stopped the millis() using header file in the hardware folder in Arduino folder

Please advice

Thanks in advance
