Project Description: This repository contains the files required for the implementation of a digital lock as described in the Project Overview document and the relevant documentation for proper use. This readme will serve as a guiding tour of the repository and detaul necessary things for minimil use.
Contribitor List: Cristian Pompey
The basic features of this implementation will allow the user to unlock and lock the device. Futher functionality can be added in the future to make it such that particular functions or data are only available when the device is unlocked.
- Nucleo L4R5ZI
- 4x4 Matrix keypad
- 1602A 16x2 LCD with PC8574T expander
- x4 Light emitting diodes
- STM-NUCLEO-L552ZE-Q
- https://os.mbed.com/docs/mbed-os/v6.15/introduction/index.html
- CSE-321-LCD display library
First you will need to clone the repository.
git clone https://github.com/CPompey1/CSE-321-DigitalLock.git
Next, build the circuit. This procedure will be detailed extensively in the project overview document.
Assuming MBED studio has been installed and setup, the user will open the project folder that has been cloned, connect their host computer to the NUCLEO via USB-to-USBC connection, and run the program.
Upon booting the program, lcd of the digital lock will display "Hello Cruel Worl Please wait....", while in maintains a temporary 5 second state of no processing. Once this message is seen, it can be cassumed that the program is working correctly if no other changes to the source folder has been made. The device will then be ready to input the 4 digit passcode, or change the password based on the #### inptu.
This will contain the main implementation and runloop of the program, all global variable declerations, and helper functions. The specifics will be detailed in the comments of the source file.
