If you are using the filtered pwm outputs as analog voltages, the frequency of the pwm 'ripple' on the voltage is irrelevant, as long as it is a high enough frequency to be filtered off. **************************************Check out AOL's list of 2007's hottest products. (http:

I would also be prepared to ignore Bascom's PWM configuration libraries. On newer devices they are sometimes not fully functional. This is no big deal since you can poke the values you want directly into the registers and not worry about the Bascom syntax. I needed to do this wit
