keypad interface for Jetson Nano

Hello:
Do you have any examples on keypad interfacing (using GPIO, or maybe even interrupt driven) with the Jetson Nano?

This isn’t what you are asking for, but if you are able to just use a USB keypad, then there is a very wide variety of cheap through expensive keypads, and no special hardware or programming is needed for that.

Thanks linuxdev. Yeah, I am looking more towards a keypad like the link below. No documentation anywhere about keypad interfacing with regards to Jetson Nano. Any other help would be greatly appreciated:
