Hi-- Does anyone have a circuit and some code for driving a 60 Hz, mains-line synced PWM? I need to create an AC dimmer for 120V incandescent lights that will operate under PIC control. I know it's been done, but I have yet to see a lucid explanation of how the routine works... Thanks-- I thought I'd see if anyone can help so I don't spend development time re-inventing the wheel! --Alan McFarland Alan McFarland's Applied Magic Custom Electronics for the Motion Picture Industry Lighting and Electronics for Models, Miniatures, Props & Sets http://www.appliedmagic.com
