I also now realize that the variable I named "prescale" is really modulating the PR2 parameter. I'm renaming it "PR2" so its not misleading. Sorry.

To clarify, "prescale" is a variable that I want to change each time the loop executes, changing the frequency of timer2.

At this point, I am guessing it has to be a constant since it's ...

So are you saying my current setup should work but with irregular pulses each time I switch frequencies? Or do I need to change anything?

I have a PIC 18F4520. I am looking to output a PWM signal whose frequency varies (which will be read by a data acquisition card and used in DasyLab).

Is this possible? Can you set the timer2 freq ...

So am I out of luck? I need to vibrate two different things at their respective resonant frequencies, so I can't really get by with one freq.

Hi everyone,

I need to output a different 2 different PWM frequencies at the same time. I am using a PIC 18F4520, which does have 2 CCP channels. I just don't know how to configure it exactly. I ...
