Kevin Braun / Mbed 2 deprecated K64F_EthLink_HelloWorld

Provides a real-time Ethernet link status for the K64F, since the K64F lacks such a function.

Dependencies:   EthernetInterface k64f_EthLink mbed-rtos mbed

Fork of K64F_EthLink_HelloWorld by Kevin Braun

Demo program for k64f_EthLink library.

IMPORTANT NOTE: The latest mbed builds (mbed 120, mbed-rtos 115, EthernetInterface 54) broke a few things in the K64F, including the k64f_EthLink - generates MDIO Timeout errors.

I recommend staying with the following mbed library versions until issues with the K64F are resolved.

mbed = 119 mbed-rtos = 111 EthernetInterface = 52
