Keep in mind that the software gurus here on blf pretty much stick to the attiny style mcu’s which have 8 legs. Those won’t work for a ring style switch. For that you might need a different style mcu that has 12 or 16 legs. Nobody here makes software for those mcu’s.

Ideally I’d like to find someone who is familiar with how the ring switches work. I have only heard they are a major pain to mod if at all. I can’t find any info on them.
