6.2. Stage 2—Basic Web Server with DHCP and Netfinder Capability
In the first stage of the demo, we learned how to generate firmware for an embedded web server using the TCP/IP
Configuration Wizard and access the embedded server from a web browser. In this stage, we will learn how to
generate a web server that uses automatic network configuration (DHCP) to automatically obtain an IP address
from the network. We will also find the embedded web server on the network using the Netfinder utility.
Note: The Netfinder utility v1.0 is not compatible with Windows Vista or Windows 7.
6.2.1. Generating the Embedded Web Server Firmware
We will now use the TCP/IP Configuration Wizard to generate a project with DHCP and Netfinder capability.
