I would design a control panel with analog indicators driven by PWM outputs of a PIC. Does anyone can suggest me a easy/friendly tutorial about PWM theory? I would prefer to know the theory and then follow to PIC implementation instead of start coding and then asking why it doesn't work as I would :) Massimo. -- ____ ____ ____ _ _ / ___)| __ \/ ___)/ /| | Dott.
