The Keypad, LCD or UART have no knowledge of each other.
The software you write does know how to communicate with
all of them. A keypad is scanned by some ports, you then
need to translate this to ASCII code if you want to send
it to the LCD, the same thing happens with the UART,
you receive the data which may already be in ASCII format
and then you send it to your display...or you may want
to send what you scanned from the keypad to your serial
port....or both...as you can see it's up to you to decide
what you want to do.
