Re: a previous comment about the DS18B20 not respecting the resolution - it does
However if the actual temperature is 23.5 all resolutions will show 23.5. If the actual temperature is 23.625 then resolutions 0 and 1 will show 23.5 and 2 and 3 will show 23.625.


Did you mean my comment?

I didn't mean to suggest that it was the software..
So if the DS18B20 receives the data correctly, it should also set the resolution and timing correctly.
But suppose 1 or more bits were received incorrectly by the DS18B20 (e.g. due to interference or because it's a "bad chip")? Then it could be that it takes the measurement with 11 or 12 bits of resolution and of course takes longer to do so.
That would also explain why an additional delay seemed to help.

Regarding the new widescreen modes: Nice feature!
