Instruction needed for 4x4 keypad

towerhand

I picked up a 4x4 16 keypad and am looking for instructions and code to set it up with a BS2 stamp.

It has 8 in-out pins.

Columns = 6 - 7 - 8 - 1

Rows = 2 - 3 - 4 - 5

There is a chip that allows you to interface a 4x4 keypad.

It is a 74C922 Keypad IC.

I have attached the pdf file for that IC, and a simple Basic Stamp program for using it.

If you don't want to buy an IC, there is another way: http://www.emesystems.com/BS2fsm.htm#keypad

There is another IC encoder EDE1144 at Jameco that look interesting...

That gives me an idea on how to add a feedback sound to my 74C92X Prop Object....
