So, I got a couple of 3216s to experiment with, because they seem to be cheaper-but-more-powerful than the older chips, but they aren't among the things listed in the fuse calculators i have seen previously, and as some of you have noticed in past threads, I'm not great at successfully computing fuse values without handholding. :P Anyone know of a thing that does this?

 

... Come to think of it, my copy of avrdude doesn't know about the 3216 either. Whee.

Install https://github.com/SpenceKonde/m... - it includes avrdude and associated configs that have the new chips...

 

As for fuses - they're substantially different, and I don't know if the old fusecalc is easily convertible.  (There are ~9 fuses now!  On the bright side, they're more obvious, better split "function per byte" -wise, an less liikely to brick a chip if you get them wrong.)

Yeah, looks like there's been a LOT of changes. Also looks like I may need a dedicated UPDI programmer for these, and can't just keep using the ISP headers I've gotten used to, but I guess I am fine with the programmer header only needing three pins, that's fewer wires to route.
