What is Embedded Web Technology?

• A spider with a PDA, Ian Macleod, 2000
• EWT is the application of software developed for
  the WWW to embedded systems.

Creating applications for embedded systems

• Things to keep in mind
• An Embedded systems memory and resources are
  limited.
• Not all embedded systems are versatile.
• Versatile Vs Non-versatile devices.
• An example of a versatile embedded system a more
  efficient device.

6
Creating embedded web applications

• Finding a solution
• What language to use?
• Micro-code
• Assembler
• C and C
• Java etc..
• Java originally created with embedded
  applications in mind.

Creating embedded web applications contd

• Which environment to use?
• Any text editor will work along with appropriate
  compiler.
• Tedious but learn the code!
• Interactive Development Environment
• Such as Borland C and MS Visual Studio
• Facilitates coding, organizing, compiling, and
  debugging applications with menus, buttons,
  icons, scroll bars etc

8
Graphical User interfaces (GUIs) and web
applications

• GUIs are important to embedded applications
• Provide an attractive and easy to use interface
  between humans and machines.
• Ex Microsofts windows CE for the palm pilot.
• No GUIs?
• Dos Vs Microsoft Windows!

9
Graphical User interfaces (GUIs) and web
applications contd

• GUI draw backs
• Can be quite large and bring lots of overhead.
• Use whats already the standard (browsers).
• Java applet and the internet.
• Browsers once static, now dynamic window to the
  internet!
