Hello, I'm newbie at programming. I'm trying to do such a thing, to write something to LCD with buttons.

For example there are 4 buttons, one goes up, other down, other right, other left. SO you can choose to which graph to write, while up and down buttons helps you to choose between Numbers 0-9.

Can you help me and write something similar in C so I can try it out and change to what I desire?

If you need more information pls ask, I will say it

Thank you in advance
