Appendices and References

This section contains all the code, schematics, cost details, task breakdowns, and references used for this project.

Appendix A: Software Code

Main Project Code

The code for the project is organized into three zip files.

GesturesSecurityV1.zip
Contains all the C code used to program the microcontroller for the touchpad security system setup.  

SecurityManager.zip
Contains the Java code used for the security manager client that is run on the PC.  It communicates with the security device through a USB cable.

Config_files.zip
Contains extra files that are needed to run the Java security manager application.

Wifi Module Test Code

Wifi_Test_Code.zip
The TCPserver.java file was used in order to create and access a TCP socket connection between the wifi module and the PC.  It would print any data received from the module, then send it 50 million strings, in order to determine if the wifi module was receiving data and sending it to the serial port.  TimersGCC644.c is a test file provided by Prof. Bruce Land that streams numbers comparing two timing methods across the UART.  It was used to test if the module was receiving any data from the serial port.  ISRserialGCC644_led.c is also based on code provided by Prof. Bruce Land, and toggles a led each time information is received by the microcontroller across the UART.  Both TimersGCC644.c and ISRserialGCC644_led.c require uart.h and uart.c, where the baud rate has been set to 38400 to match that of the wifi module.   

Appendix B: Hardware Schematics

Custom USB Prototype Board
This schematic shows the connections and hardware that go on the ECE 4760 USB prototyping board that will be used officially next year for the class, as was mentioned in the Hardware Design section.  Full details of the USB converter chip and connector are not available, and are represented by a single block in the diagram.  The full board is used for the touchpad to USB interface configuration.  In the future wifi interface configuration, the USB chip and connector are not needed. 

 Touchpad – USB Interface Schematic
This schematic represents the final hardware implementation for the final project, in which a USB connection is used in order to facilitate touchpad password entry, storage, and programming of new passwords. 

 Touchpad - Wifi Interface Schematic
This schematic indicates the hardware connections required in order to create a wifi interface for the touchpad.  This design, using the WIZ610wi module, was never successfully implemented, and remains a task for future expansion of the project.
