I was given this but have no idea on how to get it working, but it is a matrix of buttons 1-9 0 * and #. I'll sell it for $14. I have no chips for it and it has 13 pins on it. (if anyone can help me get it working thatd be cool too) I will most likely send in envelope. pics supplied

    Hey Logan;

    Don't give up on this! There are plenty of samples for working with matrix keyboards. Let's work on making this thing work for you!

    Can you post some pics and the Grayhill part number, or link to the data sheet?

    Is there a part # on it? I've used a couple of their keypads with good results. If you post the #'s then it shouldn't be too hard to locate the datasheet. Those keypads usually either have a common ground and one lead for each key or they are wired in a matrix.
