    Default Re: Resetting a slave from master mcu

    I ended up with this design, using tri-state pin on master to reset all the slaves when required. This will not be used for programming the slaves, only resets.

    It's simple, uses a single general I/O pin on master, and no extra components on slaves.

    I include that 100R res on slaves "just in case" I need them one day with my Pik-Kit.


    EDIT: For those that want to ICSP as well, look at the SN7407, and thank Mr E for the info (master on Input A, slave on Output Y)

    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!
