Hello
I am searching for a keypad code witch gets a password and if it is correct switches pic16f84's pin to lcd (I have used all of my RB0 - RB7 pins for lcd and my main circuit) and does my remaining program.
maybe some kind of multiplexing be useful, I don't know how???
could you please guide me?
I just have RA3 and RB6b left in my circuit.
Thanks
