Hopefully this can be fixed and a new keyboard firmware made available. Pretty sure I saw a post from guu that he’s moved on “to other things”, so I’m guessing any updates to PicoCalc firmware of any sort will be coming as “unofficial” updates from the community.
I’m still hopeful this work will lead to something better than what we have now. It definitely has some nice planned features. Might even be useful now, with the cleanup, power efficiency, internal RTC support (without requiring additonal hardware), etc. But I haven’t had the courage to try it yet and was planning to let it progress a little farther before I do.
