How it works
A simple exercise with a code lock application using statemachines. Codes are hardcoded, in code_lock_fsm. The application allows three attempts, after which it locks until reset
How to test
First code is setup on inputs, and confirmed via enter button, the second code is setup and confirmed. Upon correct code, the lock output goes low.
External hardware
Preferebly buttons and leds, but digilent analog discovery can also be used
