Simple 4 channel DMX controller

Very nice.

So, if I understand your comment correctly, this simple implementation really works (aside from the 24 channel minimum that you mentioned) ?

I don't know how DMX works, don't know the actual protocol, never used it, never had a need to use it (can't be too crazy hard as long as a guy reads the protocol documentation thoroughly).
BUT, every once in awhile, about once or twice a year, usually before Christmas, a few new folks log on here, and make a big to-do out of this, that, and the other thing, and can't get a DMX controller to work.
I guess I'm just wondering what the big deal was...after all, if code above works, well, jeeze, that's not so tough...
