Hi Michael,

I apologise, I wasnt suggesting your library was at fault merely that perhaps my hardware modifications were incompatible with your library due to the lack of decimal points.

Ive had a look at the data sheet and I agree a backwards 6 should be impossible so I will continue looking for a mistake in my wiring.

thanks for you help

Hi Michael,

Sorry I was changing N manually and then re-uploading the sketch. I am using a common anode display with 12 pins (7 segments, colon and 4 digits) and have got each digit displaying correctly in at least one case so I think it might be a software rather than hardware issue (I have double checked the wiring but I will have another look!)
I will have a poke about the library and see if its something to do with precision or the lack of decimal points.
One think that is really confusing me is the Backwards 6 (lighting up all segments except the top-left vertical) is this used anywhere as an error code?

Thanks for you help

Dave
