File given to use to interact with VGA Display
Maps the SSD (Seven Segment Display) onto the monitor so that we can display the state of the lock to the user.
Determines how the system will change/update when the "change" button is pushed. In the project description, the change button was used to initiate the steps that would allow the user to change the password of the lock.
Divided the 40 MHz clock of the FPGA board down to a reasonable refresh rate for the SSD. If you don't divide the clock it will be blinking because it is getting signals too frequently.
Divided the 40 MHz clock of the FPGA board down to the refresh rate of the monitor. If they weren't the same we wouldn't be able to get a constant steady image.
Used in the buttons to remove the "noise" from when the buttons have been pushed.
Determines how the system will change/update when the "enter" button is pushed. The enter button may just add another digit to the current password unlock attempt, or it can change the overall status if the password is entered correctly or incorrectly.
Small file used to check that we have finished scrolling text. (Bonus of project)
Took the status of 4 Switches that represented a HEX number (0-F) in binary.
Based on the overall status, it would be returning an array of SSD Lines that should be getting displayed.
Would return the overall status from the other child statuses (Change, Enter, ...)
Returns what the current password is.
Main file of the project, instantiated most of the core submodules and overall organized everything.
Organized the lines needed to display the scrolling text.
Updated the digit based on the current state of the switches.
Updated the SSD based on what the current lines were to be displayed.
