Hello, i am playing around with the timers of the arduino uno board, and noticed that timer0-ovf doesn't compile. what is the reason for that?? See code attached: Thanks for the info ..... Timer_8bits_16bits_interrupt.ino (1.59 KB)

ISR(TIMER0_OVF_vect) gives a compiler error

It compiles. It doesn't link, because TIMER0_OVF_vect (note spelling) is already used by the micros() and millis() library.
