Ok. This does suggest that we do use then enum in the structure. >> Indeed, why not insist that description is set?

I'll add a comment about this. Well, if we don't have a hardware schematic label, then we must have the i/o pin; we could insist that the board label the led in some way that makes some sense. r~
