AVR-Chat

I'm new to using the AVR processors and I'm trying to use the built in PWM
function.

 

I have basic PWM working and I've got 2 different pwm signals going from two
independent timers.  So far so good.

 

Using the pre-scaler, I can get close to the desired PWM frequency, and by
setting the compare register appropriately, I can set the duty cycle.

 

When I use the timer as a timer, I know how to set the exact time I need by
using the timer register to some value and having it count to overflow.  Is
there some similar mechanism to allow me to adjust the PWM frequency to
exactly what I need instead of the nearest pre-scaler value?

 

Thanks.
