What is this?

This is an Ethernet Interface library port-based on EthernetInterface. This is where the driver using TCP/IP offload (W5500/W7500), which is a market-proven hardwired TCP/IP stack, is implemented. Therefore, this library does not need lwip-eth.library.

The Socket folder contains files that implement the SocketAPI and Protocols as like DHCP and DNS.

The arch folder contains files that implement the driver for W5500 and W7500x_TOE.

The EthernetInterface.c/.h implement the functions from SocketAPI/EthernetInterface.h

The eth_arch.h implement to select TCP/IP TOE depending on platform.

What is new?

eth_arch.hThe eth_arch.h file is added to select arch depending to Target platform, we used define of TARGET_platform.#if defined(TARGET_WIZwiki_W7500) #include "W7500x_toe.h" #define __DEF_USED_IC101AG__ //For using IC+101AG@WIZwiki-W7500 #else #include "W5500.h" // W5500 Ethernet Shield //#define USE_WIZ550IO_MAC // WIZ550io; using the MAC address #endif

link()The link function is added to check Ethernet link (PHY) up or not. * Check if an ethernet link is pressent or not. * * @returns true if successful */ bool link(int wait_time_ms= 3*1000);

link_set()The set_link function is added to check Ethernet link (PHY) up or not. /* * Sets the speed and duplex parameters of an ethernet link. * * @returns true if successful */ void set_link(PHYMode phymode);

Included DHCP and DNS lib DHCP and DNS lib moved in Socket folder.

WIZnetInterface Implementations for mbed Ethenret Interface

For networking based on Ethernet network, Ethernet Interface library is provided and is composed TCP/IP Protocol layer, Ethernet, EthernetInterface and Socket. In other words, the EthernetInterface library includes the networking stack necessary for connect between mbed platform and Internet.

Each layer in EthernetInterface provides APIs to connect to the internet.
