Hi,
I try to test my new ethernet shield Wiznet W5100, I just plug into my Arduino Uno, It comes without unique MAC adress, and I used this;
Examples>Ethernet>DhcpAdressPrinter, It gives nothing at Serial Monitor.
Then I try to use this most common mac adress 0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 or 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED , and I used this example;
Examples>Ethernet>WebServer
It says "server is at 0.0.0.0" at Serial Monitor.
I searched this results and I found that I should disable the SD card pins so I added this lines at void setup(),
pinMode(4,OUTPUT);
digitalWrite(4,HIGH);
It says the same thing at Serial Monitor.
I searched this results and I found at link:Ethernet Shield Not taking address - Networking, Protocols, and Devices - Arduino Forum this ICSP pins cannot connect correctly, beacuse the lenght of the pins at ethernet shield is too long for the right connection to ICSP pins. So I cut the 1/8 off pins then I tried again.
Now it says "server is at 0.0.0.1" at Serial Monitor. When I reset the etherned shield about 24 times, It gives random things at below.

Also I tried to remove shield from Arduino and wired only ICSP pins and D10, but it gave the same result.
I checked my modem settings and there is no MAC Adress filtering, also I disabled SPI firewall.
I used my Local IP adress.If someone can help me, I will be glad,
Thanks,
Here is my codes;
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,0,106);
// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
pinMode(4,OUTPUT);
digitalWrite(4,HIGH);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
// start the Ethernet connection and the server:
Ethernet.begin(mac, ip);
server.begin();
Serial.print("server is at ");
Serial.println(Ethernet.localIP());
}
void loop() {
// listen for incoming clients
EthernetClient client = server.available();
if (client) {
Serial.println("new client");
// an http request ends with a blank line
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
Serial.write(c);
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (c == '\n' && currentLineIsBlank) {
// send a standard http response header
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println("Connection: close"); // the connection will be closed after completion of the response
client.println("Refresh: 5"); // refresh the page automatically every 5 sec
client.println();
client.println("<!DOCTYPE HTML>");
client.println("<html>");
// output the value of each analog input pin
for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
int sensorReading = analogRead(analogChannel);
client.print("analog input ");
client.print(analogChannel);
client.print(" is ");
client.print(sensorReading);
client.println("
");
}
client.println("</html>");
break;
}
if (c == '\n') {
// you're starting a new line
currentLineIsBlank = true;
}
else if (c != '\r') {
// you've gotten a character on the current line
currentLineIsBlank = false;
}
}
}
// give the web browser time to receive the data
delay(1);
// close the connection:
client.stop();
Serial.println("client disonnected");
}
