EDIT: Hmmm, looked simple enough until I saw the prices at DigiKey and Mouser. It's 1/2 the price to go with a MCP23016 and PIC 16F628.

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!
