Hi dwayne,

Yes I am talking about the 8K program memory that is in the 16F77.....what do you mean by fixed data?... do you mean that the data is not going to change if I try to write to it? if that is the case.. then how does the PWM work... I'm sure that the software changes the value of the PWM variable continuously to change the duty cycle ... can you please elaborate on that a little more for me. it is very hard for me to follow along with that "no changeable" concept.
