So , This is my first forum here in this new community ...
i was wondering about the last mode in the photo
PWM fast mode number 15
which defines ocr1a as the top , so if it is generating a pwn which register the tcnt1 will compare its value with if ocr1a is the top , how i am going to control my duty cycle in other words...?

With OCR1b as it is the only OCR left.  So this mode only has one PWM output.

Wonder if there's a whole class all learning the same thing here? I posted an answer about this very same thing to a different thread this morning...

EDIT: OK, so I'm wrong - IP addresses say completely unrelated so I guess it's just a coincidence.
