#74866 - Help needed reading matrixed keyboard
I picked up some "ADP Parts Locators" which are 8051 based with a 24 char LCD display and a matrixed QWERTY keyboard. I am trying to figure out how to read the keyboard. I am hoping to incorporate these into my home automation project. The keyboard driving circuit is located at http://www.rdrop.com/~clq/circuit.jpg and the keyboard layout is located at http://www.rdrop.com/~clq/keyboard.jpg.

It has been several years since I have worked on 8051 assembly, so any help figuring this out would be appreciated.

Thanks
Carlos
