Introduction
W5100 is a multi-purpose single internet interface chip, integrated 10/100 ethernet controller inside,and applied to embedded system which is high integration, high stability, high performance and low cost.
It can be connected to Internet without operating system and compatible with IEEE802.3 10BASE-T and 802.3u 100BASE-TX.
It contains TCP/IP protocol stack that is full-hardware and verified by market for years, Ethernet medium transport layer and physical layer.
You don’t need to consider the control of Ethernet, and just need simple program of ports.
Specification
- Various interface: Direct Bus, Indirect Bus and SPI Bus
- Supporting TCP/IP protocol stack of hardware, TCP,UDP,ICMP,IGMP,IPv4,ARP
- Up to 4 independent ports
- Integrating 16KBYTE transmit-receive cache
- Outputting multiple indicating information,including RX,TX,Full/Duplex,Colision,Link,Speed
- Supporting automatic conversion of polarity
- Coming with Internet access, dual row of 2*14 2.0mm pins

// Enter a MAC address and IP address for your controller below.

byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1,177);//modifying according your own IP
// Initialize the Ethernet server library
// with the IP address and port you want to use

Result
After uploading program, you can input you own IP(matching with codes)on browser, and then press the “ENTER”key, showing the result(sometime you need to restart control board).
