I'm trying to interface a 16*2 lcd display and 4*4 keypad with lpc 1343 board. I have successfully finished interfacing the lcd. but can't find the keypad.h header file to interface the keypad. I'm using lpcxpresso v7 IDE. i'm comfortable using keil uvision5 too. help with the keypad interfacing code would be most appreciated.
 

Hello!

You mean you have the C / CPP file and you don't have the header?
Or you don't have anything?
I guess you should write the file yourself. A 4x4 keypad is really not a big deal
to implement.

Dora.
