    Default Re: Reusing PGC & PGD pins

    Does this look "safe" to use an opto-coupler to be able to reuse ICSP Clock & Data pins?

    I'm using my old MeLabs USB programmer with stock header; circuit is powered by wall adapter/7805.


    EDIT:

    1. Should I be better to use an opto with a CurrentTranferRatio of 0%?

    2. Is anything stopping me from doing the same thing to MCLR with quad opto?

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
