Yeah, I recall hearing something about that too… but I don’t remember if it was ever resolved. However, I’m pretty sure Mike C has OTSM working on bigger MCUs like tiny1634… so I’m guessing there’s probably a way to do it on tiny85. He says he gets about 15 seconds worth of OTSM with a 47 uF capacitor… and all Bistro needs is about 2 seconds.
I’ve been procrastinating for years about getting the Bistro-HD code merged into mainline Bistro. Flintrock’s changes are far too deep and too broad to be easily merge-able, so it’s a large task. Perhaps I could get just the basics of OTSM working though, without all the other changes. Or I could potentially add some offtime support to FSM, and then the UI toolkit would cover both e-switches and clicky-switches.
Not sure when I’ll have time and motivation though.
