If you want to get the number 23 from two seperate keypresses
you can setup a couple byte variables to hold each key value
received, and
1. Multiply the first digit received by 10
2. Grab the second key value and simply add it to the first.
IE,, the first digit received is 2, and you store it in B0, then B0 = B0 X
10.
you now have 20. The second digit arrives and you add it to B0. You
now have the number 23........ after two key presses.

http://www.rentron.com/Ser-Key.htm This is a 10-key serial key encoder PIC
that takes key entry from simple push-button switches. You won't need to
buy an expensive keypad, just use any el-cheapo normally-open push-button
switches to build your own 10-key serial keypads.
It was specifically designed for the Basic Stamp, and the
baud rate can be changed on-the-fly from N2400 to N9600.

I have some questions about keypad:
1- Keypad gives the value of the key that has been pressed.
How can I do the following with BS2:
pressing key '2', the display is '2'and when pressing key '3',the
display is '23'.. and so on ?
2- Where can I get inexpensive keypad kit.
3- I need information about EDE 1144 IC keypad encoder from Jameco.
Thank you in advance
