do not understand kbd.c

[masary]

Hi,
I want to use KBC-18PS2 - 18 key numeric keypad in my project. I read kbd.c but did not understand.
My questions are:
1. can this example code can be used with KBC-18PS2 - 18 key numeric keypad?
2. what is different blue and black keypad?
3. how to know the result? is it connect to LCD or monitor?
4. how to connect? or waht is the connection?
5. where is the column pins? ( it say port used has pull-up resistor or LCD on the coloumn pins).
Sorry, I never use LCD in my project.

Thanks.

There's a driver in the code library that might be helpful, but I can't
really offer any more help because the name of the product you
posted doesn't show up very much in Google. I can't find a current
web page listing that product name or any reasonable variation of it.

Here's the code library link.
