4x4 keypad examples

[Bobw]

Looking at possibly using a keypad as opposed to several switches.
I have been playing with the sample file that displays the number for the key you pressed.
Is there a sample file that will display a number based on several key presses to be passed to a variable?
I need to use both negative and positive numbers from 1 to 3 digits.
I think I now understand how the keypad generates either a number or a byte, but grouping them together was escaping me.

Hi Bob, there are different ways of doing this.
One way can be found in this flowchart:

Martin,
Thanks, I will give it a look.

Wow
Many things going on there. Won't be able to pick it apart till this weekend.
I think I see how you are keeping track of the entered numbers.
Will try to save off what I come up with so others can use it.
