Hey! I recently got a keypad to use with the PIC 16F84 for an application. The problem is I've tried anything but I can't make it work. It's supposed to give BCD code as an output but I don't know what kind of decoder circuit it needs to do that! Take a look at the picture and let me know if you've worked with something similar before. (it's supposed to be a touchpad, if that's important...) Thanks in advance, Argiris
