I need a to program a tiva TM$4$c$123$GXL to work as a door lock. The Assembler I am using is Kiel Uvision $5,$ The goal is to set a pin with the number pad, after setting it the user has $4$ attempts to input the right pin before they get locked out $($this to be reset with the $*$ key on the number pad$)$ When they input the right pin the tiva would output to a stepper motor and turn it$.$ The user reads info off a $16$x$2$ lcd screen
