I too have been playing with this idea (but only for about a year!)

I know for a fact that is IS possible to decode DMX with a PIC for two
reasons:

1. The last time I looked inside a Zero 88 BetaPack fitted with a DMX
Receiver there was this 17C42 looking back at me.

2. It is possible to bit-bang DMX through a 16C54 - I have chip here
>from a company called Stortfield which does that - though I can't get
the little bugger to work!

3. There was a company at PLASA this year, Artistic Licence (UK) Ltd,
who sold pic based DMX receivers - They have a WEB Site -
http://ourworld.compuserve.com/homepages/artistic/.

I guess the problem is that all the people make LARGE sums of MONEY
selling these beasties and consequently no one is willing to give
anything away.

I'm currently working on a 16C54 based system for which I have a
schematic and am slowly developing the code - I reckon there's just
about enough time in the stop bits to stuff an 8-bit parallel word
out. But as I said things are progressing VERY slowly! When it finally
arrives I guess it will probably be PUBLIC DOMAIN when completed,
there must be people around who could improve on my coding - in fact I
guess anyone could improve on my coding

Anyone else out there with any experiences they are willing to share?
