Looking for code for
2-key rollover for n keys (n buttons connected to separate GPIO pins)
Looking for #Python code to detect two-button-presses on (let's say) 4 buttons, in general detect "2-key rollover" on n GPIO pins.
( https://en.wikipedia.org/wiki/Key_rollover : "Key rollover is the ability of a computer [keyboard] to correctly handle several simultaneous keystrokes.")
For 2 buttons, this is easy.
