Q: Does keypad module/pins need to have external pull ups?

A: No, internal pull ups on the device are sufficient.

Gandhar,

how to use the internal pull ups?

Is it the default setting or could we make some settings on software?

Pull ups are always active AFAIR and you thereby don't need to so anything special in SW :-) - Please correct me in case I'm wrong
