When you place your question at the end of an old thread, it is confusing. We discourage the practice, especially when your topic has nothing to do with the hijacked thread.

You can always look through the app notes on the microchip site for ones pertaining to PWM techniques.

 

Compared to is older brethren the 16f877 has much more to offer at around twice the price. As for all Microchip controllers the datasheet (pdf) and the MPLAB assembler IDE are available for free...in the internet so check it out.
