Statement of Work

• Goal
• Create a GUI using QT Creator on the 8 Phylon
  Open Frame LCD to control GIZMO audio and video,
  connectivity via phone, and automate network
  connectivity.
• Specifications
• Integration of executable file from computer to
  GIZMO board with x86 embedded Linux
• GUI to control GIZMO applications (audio, video,
  and remote control via phone)
• Gather information about available networks
• Automate network connection (IP, DNS, etc)
• Resources (Provided by Sponsor)
• GIZMO Truck
• 8 Phylon Open Frame LCD
• Calit2 Lab

Technical Content Setting Up Linux and Qt
Creator

• Install Linux-based operating system
• Update necessary development packages and
  libraries for Linux
• Download and install Qt 4.5 development version
• Download and install Qt Creator Integrated
  Development Environment (IDE)

7
Technical Content Learning How to Program with
QT

• Qt uses C with several non-standard extensions
• Based on a system of signals and slots to connect
  UI to actions and events
• Includes a rich set of widgets (controls) that
  provide GUI functionality
• A wide variety of plug-ins and dynamic libraries
  are available within the open source

8
Technical Content Test Programs made with Qt
Document Editor Replaces a set variable in a
given text document
Text Finder Searches a given text document for a
keyword from input
9
Technical Content Hardware Integration

• GIZMO is loaded with
• Embedded x86 Linux operating system
• X11 window server
• A flash card to boot files from
• VGA interface used for display
• USB ports
• Touch screen application will load on startup

Technical Content Network Connections

• Switching between networks
• Change a variable in a configuration file (text
  document) by pushing a button
• Four defined servers to connect to
• UCSD
• CalMesh
• Wiisard (10.1)
• Wiisard (10.2)
• Displaying server info

12
Status of Work

• Currently improving on functions of our network
  connections interface
• Display server info (i.e. signal strength, SSID)
• Show a list of detected networks in the area
• Create the option to add and connect to any
  detected network

13
Change in Goals

• Two changes have been made to our original goals
• Original Control movement on the touch screen
• Change Not practical because the touch screen is
  mounted on GIZMO vehicle would move while
  touching the screen
• Original Switch between four set networks
• Change Have the option to add and connect to any
  detected network, instead of having a set of
  predefined networks

14
Hardships

• Learning a new operating system
• Linux overwriting Windows
• Missing drivers
• Learning Linux commands
• Downloading and compiling development packages
• Missing Qt Creator dependencies
• Qt Creator depends on Qt 4.5 development
  environment
• Missing libraries
• Making binary files
• Learning new type of programming (QT 4.5)
• Qt functions with its own specific libraries
  (based on C)
• i.e. using object QPushButton in GUI requires
  QPushButton.h
