Need some help. I am trying to program a ADAfruit feather M0 for use with a matrix keypad.

  1. For the keypad, I need to scan pins and think I need to write a pin low to read the opposite pins of the matrix. I ham having problems getting the pin back to normal state, not high or low so I can read the other side of the matrix.

  2. I need to send over a enter key, but can’t find

Do you have any details on the keypad you’re using? maybe a part number or tech sheet?
