# Ethernet with lwIP

About:
This example application demonstrates the operation of the F2838x microcontroller
Ethernet controller using the lwIP TCP/IP Stack. This example sets up the Ethernet 
MAC. F2838x device receives and sends data over UDP.

Test setup

F2838x Control Card connected to a PC/laptop  on the Ethernet port.
PC/laptop runs the SocketTest/’Packet Sender’ software, configured for the IP Address and port . \
Keywords ‘START’ and ‘STOP’ are used to send and stop receiving messages respectively
Received data is stored in ‘buf_rx’ array and data to be transmitted is stored in ‘buf_tx’ array on CM core of F2838x device
Examples is Interrupt based with a callback function ‘udp_rx_callback’ which handles the received data from the SocketTest/Packet Sender software.
