#151846 - Matrix Keypad Pins. Responding to: ???'s previous message |
It can be a disaster to configure the output scan row side of a matrix keypad to push-pull outputs. When the user mistakenly presses two keys in the matrix on the same column you have the two scan pins fighting like two cats in a burlap bag.
