6.4.3. Re-Building the Project and Viewing Results
Once the file arrays are updated, it is time to re-build the project and view the results.
6.4.4. Viewing the uWeb Embedded Web Server
The “Hello World” server used in the demo up to this point contains a single static web page. Another example
server included as a HEX file in the Examples\C8051F12x_13x\Ethernet\HTTP\uWeb folder is the “uWeb” server.
This embedded web server contains multiple HTML pages, images, a Java temperature display applet, and CGI
script capabilities allowing the detection and control of an LED state. This server demonstrates some of the
capabilities of the Silicon Laboratories TCP/IP stack. The following instructions can be used to download the
“uWeb” server.
