recently in learning STM32 and w5100 network communication,
Above the mbed found a routine, compiled after the don't know how to view? PC with friendly Ethernet debugging serial debugging assistant, don't know how to set parameters should be? IP address and port should be how to fill in? Click start always prompt the SOCKET connection is successful,

The following is a code

# include "mbed. H"
# include "WIZ820ioInterface. H"

Serial PC (USBTX USBRX);

/* *
* D11 - MOSI pin
* - D12 MISO pin
* D13 - SCK pin
* D10 - SEL pin
* NC - Reset pin; Use D5 otherwise the shields took the get into reset loop
*/
