@DrJeff , I plan to document everything and post at the forum later, probably once I incorporate the IR emitter in my project. ;-)

I forgot to mention the zero-cross detection (on pin2), you will need it if you dimm regular AC bulbs (doesn't matter how many dimmer channels you have, only one zero-cross is enough).
The picture above show the zero-cross on top and one dimmer channel on bottom.
