Can you upload a drawing of how this is connected? That should help Ben_C out, se earlier post.

Also, i know the dechex macro is a pain, it is different in my norwegian version, too.
Maybe i will rewrite the sheet, so it can do without the macro.

Please also note the updates to my web, i got the new schematics from my co-developer, Jorge (aalbea), so i have put it all on the web. There is also links to the datasheets of all components used.
