library for PRF-dominant PWM

Projects Libraries
1

Is there any library in the Arduino world that allows one to, in general, more exactly specify the PRF in exchange for ( if and as required) less precise control of the duty cycle/pulse width? All libraries I've encountered/found ( not all of them, admittedly) seem to emphasize controlling duty cycle ( usually to one part in 1024) at the expense of poor PRF control...

And PRF means ?

PRF = pulse repetition frequency

Thanks. I can't say I understand what you want to achieve.

The normal analogWrite() frequency is about 490Hz and AFAIK it is quite stable. It is possible to change that if you need to - perhaps to reduce motor whine. I have done that but I can't remember the details off the top of my head.
