I am at my wits end and very close to throwing my Arduino an ethernet shield at a very hard wall unless someone can save my frazled brain
I have an Arduino 2560, a W5100 shield and a W5200 shield to replace it with for better performance
With the old 5100 I have written lots of sketches and can get it running fine. But, it is limited in performance and wanted to improve things with a 5200
So, bought this shield http://www.ebay.co.uk/itm/172153910144?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT , fitted it and downloaded the Ethernet V2_0 library
In my existing sketches I change the #include <Ethernet.h> to #include <EtherentV2_0.h> but nothing works.
SD doesn’t initialise and see any files and ethernet port doesn’t work. The lights on the shield and RJ45 socket come on but nothing works
Now I have gone back to first principles and uploaded simple examples from the EthernetV2_0 library (webserver and Webserver wtith SD) and they fail too. Webserver just says that IP of the sever is 0.0.0.0 and the one with SD just fails to initialise the SD card
I have included an extra line in those sketches of pinMode(53,OUTPUT) for the mega’s hardware SS pin
Please can anybody help. I am sure I am just being dim but I am so frustrated with the thing its unreal.
thanks in advance
