Ethernet Shield not recongized
itamax 2014-04-15 00:53:49 7540 Views8 Replies Hello,
I recently bought an Ethernet Shield for Arduino - W5200 which I plan to connect to an Arduino Uno Rev.3 board.
The problem I have is that the link and the speed leds are turned off (the other leds are ok) when I connect an ethernet cable to the board (off course I tried with several cables) and the shield cannot connect to the LAN (I tried also different routers)
I was suspecting that the board was faulty and I get a replacement from the supplier but I had the same problem.
Am I doing something wrong ?
Any advice is appreciated.
Many thanks.
Massimo

2014-04-23 01:14:01 Hello,
I can now now use the Ethernet shield correctly.
I have a question on the pins reserved by the Ethernet shield once connected to an Arduino Uno board.
I understood from various documentation that Pin 10,11,12 & 13 are used; so far so good.
However from the code provided it seems that also Pin 3,8 & 9 are needed. Can you confirm ?
Thanks

I tried the code and it works !
I can see the web page displaying the value of each analog pin correctly.
Many thanks

I have corrected the code.

********* END SKETCH ********
The purpose of the code is simply to verify the connection to the LAN and to internet. This is the reason why the loop is empty.
Executing the code I get this result in the serial monitor:
[size=10pt][font=courier]IP address is: 0.0.0.0
Connection result: 0[/font][/size]
I confirm that when I connect the cable to the RJ45 socket I hear the sound (I tested the cable with another device and is working properly).
What do you mean for "[i]And whether the first time the other LED is light?[/i]"
Thanks for your help.

itamax 2014-04-16 18:44:10 Hello Sir,
I am sorry your code can't be verified.
It lost some defination of the parameter. like ip address. And also the loop function.
Could show me your whole sketch?
When you plugged the Ethernet cable in the slot, did you hear the sound like "ka"?
And whether the first time the other LED is light?
