Board-to-Board Ethernet (FRDM-K64F)

Has anyone tried communicating between two FRDM-K64F boards directly via Ethernet without using a PC in between? For my project, I only need to communicate one way, so one board will only be talking and the other will only be listening. I don't know much about Ethernet protocols, so any help is appreciated.

Have a look in the handbook at the networking section. You should be able to set one up as a tcp/udp server and the other as the client using static IP addresses.

Beware of the wiring... you may need a special cable https://en.wikipedia.org/wiki/Ethernet_crossover_cable

Accepted Answer

No need to worry about special cables - the board has an auto MDIX phy on it.

Perfect. It works! That was easier than I expected. :)

Also, Bill is correct. No crossover cable is needed.
