Hi all

I like to construct a dimmer to control the intensity of an incandescent bulb using PIC16F676. Is it possible to utilise the external interrupt for zero crossing detection and internal interrupt i.e. TMR0 overflow interrupt for firing angle setting in the same code? If so, please post a small piece of code or any link on it.

regards,

swapan

Here's a previous discussion thread which covers your topic:

PIC controlling AC loads

There are literally dozens of example projects posted in the above thread, so you can pick and choose.
