Bruce, thanks for the awesome post. I feel edumacated now!

Actually before I saw your post I changed a few things and got the board working perfectly. I'll include your port setting changes to remoe the potential RMW errors. Thanks for that suggestion.

However, I am unable to implement the reversal of dip swith settings as the board is laid out and silkscreen shows 1, 2, 4 and 8mS.


So, has anyone ever seen 6 LED's pulling over 1.5KW?!
