Changing PWM Freq on Ardu MEGA, Effect on delay()?

Hey,

im thinking about Changing the PWM Freq. of an Arduino MEGA.
I dont want to change all Freqencys, just from some pins (about 2 or 3, i dont need more).

If i change lets say Timer 3 or 4 on the MEGA, does this affects the delay and millis() Functions? I've read about it but I dont found a list like timer 1 -> delay change, tomer 2 -> no change...

Thanks :slight_smile:

delay() and millis() use Timer 0.
