Just want to thank everyone who kindly assisted with suggestions on this=20 subject. Everything works fine now. This is what happened. On Friday I was going away to visit my mother who lives 80 km or so from=20 us. Safe distance form any environment problems I would have at my=20 location so I therefore took down the two boards to take them with me=20 together with one of my lab power units. To make sure I had the correct=20 firmware in them I burnt it in on both boards (This I have done plenty=20 of times before, never even changed the preset path for the files in the=20 programmer when I programmed them now from last time). Noticed that after programming that one lamp that always been of before=20 now was lit. Reseted both boards and now everything was working!!! No=20 problems at all. Though that this could have something to do with the time of day. So I=20 tested it several times since then and it still works. I have a wood pellets burning furnace with a big motor for the pellets=20 transport screw that I had turned of for the season an I tried to start=20 it again to see if that could be the problem but everything works OK. I have tested, double checked and checked again so many times that I=20 would be surprised if it was something in my setup that caused this=20 problem before. But why it did not work before puzzles me. I don't feel OK with this as I can't explain why it now works but I=20 guess I have to go on with the project anyway.... /Ake Dave VanHorn wrote: > >> Just o make sure I understand.
