Ethernet W5100网络扩展模块，可以使成为简单的Web服务器或者通过网络控制读写的数字和模拟接口等网络应用。可直接使用IDE中的Ethernet库文件便可实现一个简单Web服务器。

同时该版本的支持mini SD卡（TF卡）读写

该扩展板采用了可堆叠的设计，可直接插上，同时我们的其他扩展板也可以插上去。

IDE中的实验代码：

/*

* Web Server

*

* A simple web server that shows the value of the analog input pins.

*/

#include

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

byte ip[] = { 192, 168, 0, 15 };

Server server(80);

void setup()

{

Ethernet.begin(mac, ip);

server.begin();

}

void loop()

{

Client client = server.available();

if (client) {

// an http request ends with a blank line

boolean current_line_is_blank = true;

while (client.connected()) {

if (client.available()) {

char c = client.read();

// if we've gotten to the end of the line (received a newline

// character) and the line is blank, the http request has ended,

// so we can send a reply

if (c == '\n' && current_line_is_blank) {

// send a standard http response header

client.println("HTTP/1.1 200 OK");

client.println("Content-Type: text/html");

client.println();

// output the value of each analog input pin

client.print("welcome to tinyos");

client.println("

");

client.print("//*************************************");

client.println("

");

client.print(

);

client.println("

");

client.print("//*************************************");

client.println("

");

for (int i = 0; i < 6; i++) {

client.print("analog input ");

client.print(i);

client.print(" is ");

client.print(analogRead(i));

client.println("

");

}

break;

}

if (c == '\n') {

// we're starting a new line

current_line_is_blank = true;

} else if (c != '\r') {

// we've gotten a character on the current line

current_line_is_blank = false;

}

}

}

client.stop();

}

}
