Ethernet W5100 Network Expansion Board SD Card Expansion based on For Arduino

Description:

W5100 network extension module,can make for Arduino can became simple Web server or through the network control read and write for Arduinodigital and analog interface etc network application.Can directly use Ethernet library file in the IDEcan achieve a simple Web server.

At the same time, this version supports Mini SD card (TF Card) to read and write

The expansion board adopts the design of stackable, can be directly inserted into the for Arduino, and other extensions of our board can also be inserted.

Test Code:

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

#include <Ethernet.h>

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(www.tinyos.net.cn);
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();
}
