Hiya Guys,
Eh I'm out looking for an interfacing chip for a 4x4 keypad so I can free some pins on a pic. So far searching through google hasn't turned up any results. Nigel's tutorials have provided me with a stable platform but taking up 8 pins will be too much for some of my projects. This is why I'm looking for an interfacing circuit so I can cut down on the pin count. Later I'll browse through some of my electronic books to see if I have any info but thats where the net comes in handy.
Cheers Bryan
