3. 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.”

4. Basic Hardware Example

5. Creating applications for
embedded systems:
Things to keep in mind:
An Embedded system’s 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.

7. Creating embedded web
applications cont’d:
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
(GUI’s) and web applications:
GUI’s are important to embedded
applications:
Provide an attractive and easy to use
interface between humans and machines.
Ex: Microsoft’s windows CE for the palm
pilot.
No GUI’s?
Dos Vs Microsoft Windows!

9. Graphical User interfaces (GUI’s)
and web applications cont’d:
GUI draw backs:
Can be quite large and bring lots of
overhead.
Use what’s already the standard
(browsers).
Java applet and the internet.
Browsers once static, now dynamic
window to the internet!

10. Examples of EWT

11. Examples cont’d
NASA
RoomCam
Wind tunnel

13. Conclusion
EWT is vastly becoming an important
tool in our daily lives.
