Web server

This demonstration is an embedded web server based on the lwIP stack. It allows
addressing the STM3220G-EVAL board as a web page using your web browser to control
the four LEDs on the board and the potentiometer level.
The STM32 Ethernet peripheral is configured in MII mode with speed auto negotiation and
the Clock for the external PHY is provided by the STM32 through the MCO pin.

Figure 13. Web server DHCP server reply

The web server sub-demo supports the DHCP protocol and, if the DHCP is enabled in the
host side, an automatic IP address is assigned to the board; otherwise, a static IP address is
used instead (192.168.0.8).
