Project Setup

• For the Zybo Z7-20 setup, click here.
• For the ZedBoard setup, click here.

Requirements

• Software
  • Vivado Design Suite 2019.1
• Hardware
  • Zybo Z7-20 Zynq-7000 Development Board, or
  • ZedBoard Zynq-7000 ARM/FPGA SoC Development Board
• Peripherals
  • PMOD seven-segment display (SSD)
  • Pmod KYPD 16-button Keypad
  • One passive buzzer (Zybo version)

Instructions (Zybo/Zedboard)

1. Open Vivado 2019.1.
2. Using the tcl console, type the following:

cd <change to extracted_folder>/<lock or lock_zed>
source ./lock.tcl # if using Zybo, or
source ./lock_zed.tcl # if using ZedBoard

3. Create a new HDL wrapper for the block design.
4. Run synthesis and implementation, then generate the bitstream.
5. Go to File > Export > Export Hardware. Make sure that the "Include Bitstream" box is marked.
6. Go to File > Launch SDK.
7. Once the SDK is launched, go to File > New > Application Project.
8. Fill up the form with the following details:

Field	Value
Project Name	"Your preferred name"
OS Platform	Standalone
Hardware Platform	design_1_wrapper_hw_platform_0
Processor	ps7_cortex a9_0
Language	C

9. Click on Next, select the Empty Application template, then click Finish.
10. Copy the contents of (zybo or zybo_zed)/src into the src folder under "Project Name".
11. Under Project Explorer, right-click on the project folder, click on C/C++ Build Settings.
12. Under Libraries, click on Add, then type m.
13. Program the FPGA.
14. Right-click on the project folder, click on Run As > Launch On Hardware (GDB).

Operating Modes

• Guest Mode
  • Allows the user up to five times to guess the combination. Corresponding characters and LED patterns are generated based on the current input status.
• Administrator Mode
  • A two-stage process that lets the user modify various information:
  1. Switch change: A switch combination must be applied to the lock in order to move on to the second stage.
  2. Keypad input: The lock will prompt for the administrator password. Once verified, the user will be able to reset or change the lock/admin combinations.
