Keypad Interfacing
Hello guys.
Ive to interface a 12 keys keypad into with my PIC microcontroller (PIC 16f877a). With the help of this keypad i want to control my LCD display which is already being attached with the microcontroller. Please help me with that. I need the circuit diagram as well as guideline on how to program the PIC too.
Thanks

You can also see the schematic and sample pbp files for the LAB-X1 development board. Both are at www.melabs.com.

I did not know there was a manual for keypads?
You can have them on a port or two and then read the port(s) or use a shift register and read that.
Not much more to it.
