4 Quadrant dc drive with 16F877

Hi,

You can set up the hardware PWM for a constant frequency output without any code overhead. Then you can sample your pot and dump it to the PWM duty cycle. Both are 10 bits. Easiest way to get a pot controlled variable dutycylce signal.

I have an algoritm for how I create pulse to drive mosfets. I take the value from tako and I compare it the control voltage (I set it with pot at first) and I get new D. I want to see some code examples in assemble for analog to digital conversion by using a pot in pic input (1* to set reference voltage and 2* for tako feedback). In my program, pic is continuously take voltage which comes from tako, and change duty cycle. If you give me some code examples or web pages includes written programs in these topics, i will happy more.
Thank you for your interest.
