LPC17xx/40xx LWIP TCP Echo without an RTOS

Detailed Description

Example description

Welcome to the LWIP TCP Echo example using the raw API for standalone (without an RTOS) operation. This example shows how to use the raw API with the LWIP contrib TCP Echo example using the 17xx/40xx LWIP MAC and PHY drivers. The example shows how to handle PHY link monitoring and indicate to LWIP that a ethernet cable is plugged in. It also shows how to manage input packet handling and reclaim transmit pbufs once they are transmitted in the main processing loop.

To use the example, Simply connect an ethernet cable to the board. The board will acquire an IP address via DHCP and you can ping the board at it's IP address. You can monitor network traffice to the board using a tool such as wireshark at the boards MAC address.
