As far as getting more resolution from the PIC processor, Your out of luck. You can always build your own digital pwm circuit with hardware if you are so inclined.
But Darrel did not do this in his code, prefix with "_". Also as Talat has said he is following Darel's example for "16 bit PWM using CCP1" which obviously worked for Darrel, Bruce and Norm.

So Talat 16 bit PWM is possible. I have read the whole thread and the datasheets for the 18F452 and the chip you are using 16F1827.

The first possible issue Darell said his code was for 18F's only in post 3 does anyone know why not 16F's? The 16F has CCPx compare mode.
With regard to the 16F1827 I think CCP4 has the required features needed and CCP1 does not but I need more time to re-read the datasheet but in the meantime it would be helpful if some one could confirm which CCPx should be used.
