I thought that the following code would give me change in pin 8's state at about 125KHz. I think it's setting the overflow interrupt on Timer0. bool state = HIGH; void setup() { pinMode(8, OUTPUT); noInterrupts(); TCCR0A = 0; TCCR0B = 0; TCCR0B |= (1 << CS02); TIFR0 |= (1 << TOV0…

Even if you don't need millis() function, you can't use TIMER0_OVF_vect because the Arduino Core has defined a Timer0 overflow interrupt (a.k.a. TIMER0_OVF_vect). If you write multiple ISRs of the same vector, a compile error will occur. Try using TIMER0_COMPA_vect instead of TIMER0_OVF_vect. The…

That makes sense. Thanks.
