Arduino Ethernet Shield 2 not working

Question

I am currently trying to get the Ethernet Shield working on my Mega. I was trying to run the Webserver example but the program seems to stuck at one point, so I tried to start from scratch.

This is my test code:

#include <Ethernet.h>
#include <SPI.h>

byte mac[] = {
  0x90, 0xA2, 0xDA, 0x0F, 0xF6, 0x3D
};
byte subnet[] = { 255,0,0,0 };
byte gateway[] = { 2,0,0,1 };
IPAddress ip(2, 0, 0, 1);

EthernetServer server(80);

void setup() {
  Serial.begin(9600);
  Ethernet.begin(mac, ip, gateway, subnet);
  Serial.println("Ethernet started");
  server.begin();
  Serial.println("Server started");
}

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println("Loop");
}

The output I get from the serial console is:

Etrted
Ethernet started

So I think the program gets stuck inside the EthernetServer::begin() function. I am aware that there are earlier versions of ethernet shields which are not compatible to the mega, but the vendor of my shield says it is.

Also I don't understand, why it outputs the first line.

Thanks for your hints!

Answer 1

Arduino.cc and Arduino.org are not the same... Arduino.org, who is selling the ethernet shield 2, has their own IDE with the correct library! You can download it at http://www.arduino.org/downloads and the source can be found at https://github.com/arduino-org/Arduino/tree/1.7.4/libraries

Answer 2

Try this code form (http://www.arduino.cc/en/Tutorial/DhcpAddressPrinter):

#include <SPI.h>
#include <Ethernet.h>

// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = {  
  0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };

// Initialize the Ethernet client library
// with the IP address and port of the server 
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;

void setup() {
 // Open serial communications and wait for port to open:
  Serial.begin(9600);
  // this check is only needed on the Leonardo:
   while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }

  // start the Ethernet connection:
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // no point in carrying on, so do nothing forevermore:
    for(;;)
      ;
  }
  // print your local IP address:
  Serial.print("My IP address: ");
  for (byte thisByte = 0; thisByte < 4; thisByte++) {
    // print the value of each byte of the IP address:
    Serial.print(Ethernet.localIP()[thisByte], DEC);
    Serial.print("."); 
  }
  Serial.println();
}

void loop() {

}

And post what the serial monitor output is.

Try this:

NB. You can reuse your code written for Arduino Ethernet Shield, simply replacing

#include <Ethernet.h>  -->  #include <Ethernet2.h>
#include <EthernetUdp.h>  -->  #include <EthernetUdp2.h>
