I am using a 4x4 matrix keypad and I'm trying to store an input from the keypad subroutine for use in a password checker. I have the keypad working and have a password checker that works using the Debug window.
My question is what command or series of commands is necessary to store the input from one subroutine and use it in another?
My keypad is connected via P0 through P7 with the use of 220 ohm shock resistors and 10K ohm pullups...
