This "Hello World" program is used in conjunction with the Ethernet_UDP_server program. It communicates between two FRDM-K64F boards via the Ethernet protocol.
1. Connect the Ethernet cable (standard, not crossover) between the two FRDM-K64F boards.
2. Then flash the server board with Ethernet_UDP_server and the client board with Ethernet_UDP_client. 3. Open two Tera Term (or other terminal) windows. One will be the server and the other will be the client.
4. Press the reset button on the server board (note the green LED will light up, indicating it is the server board). 5. Press the reset button on the client board (note the red LED will light up, indicating it is the server board).
6. You should see the output below in the terminals.
