WIZnetInterface for ARMmbed

    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.
