Conclusion
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.”
Tempest
Basic Hardware Example
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”.
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 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…
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!
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!
Examples of EWT
Examples cont’d
NASA


RoomCam
Wind tunnel
Conclusion
EWT is vastly becoming an important
tool in our daily lives.
