Hi Robert, thanks very much for the info. I see the mention of 4.7k resistors in the getting started info, I'm not sure how to check whether the boards have pull up resistors on the specs info though. There's a link for "wire library documentation" on the page that might elaborate, but the Arduino site is getting a page not found link.
Off hand, do you know if the Nano Every has pull up resistors? I don't mind adding some, but would be handy and a bit tidier if I didn't have to.
Regarding the broken link I mentioned on my initial post, those pages are working fine for me now, or perhaps I was too tired at the time and being a bit dim thinking I was stuck on a page loop when I wasn't.
Thanks again
