Is it possible to setup a key matrix with GP2040-CE?

Hi, I love how easy GP2040-CE is to setup and how little the input letancy is, so instead of only hitbox I wonder if I can use it as a keyboard. It would be so nice to make a custom half keyboard for some competitive games.

Hi @PuTaTuo ,

Matrix is not possible with GP2040-CE.

You can put it in keyboard mode and use single GPIO -> switch and assign it to a key.
