The Bass beat Filter II ???
Huh !!!
The manual clearly tells Pwm outputs garbage ... and needs a RC or more sophisticated filter.
Now just keep in mind PWM is only good to get some "analogic" output from the PIC.
Another STAMP " Not so good a function " survivor.
Now, if you want to keep the PWM function ... just compare a sawtooth to this "analogic" voltage ( once filtered ) and you'll get a neat "real PWM" at the output of the comparators.
a quad LM 339 sould do that job very honestly ...
But we remember DARREL's slow PWM is the shiny solution to what you want to do.
Ah, last point ... and not least ! you'll discover the motors have a low PWM ratio thresold not to make some noise and unwanted heating while not turning. one more thing to add !!!

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
