Hi Nick,
This is superb stuff just what I was looking for.
It would be great if we could get some sort of db going with the signature bytes xrefed against boards.
I will try on my boards and post the outcomes.
I know it probably sounds grandiose but I think it would be great to eventually end up with a diagnostic sketch, that reported on as many features as possible.
I've always enjoyed looking under the hood, and remember years ago using code from Dan Brown to create a full DOS diagnostics suite. It came in really handy when I was freelancing as a repair man as I could run my program and drill down to obvious issues rather than hunting for the elusive needle in a haystack.
Kind regards to all "Hoodies",
