Good work dinau. There is a couple of things I'm not a fan of, not something you could do when directly porting, but something I feel is needed to be fixed in the future. Mainly making it easier to pick between W5100 and W5200, and allowing different SPI ports to be included. The main purpose of these changes is to allow more control within the IDE.</p> <p>I also noted that a few example sketches is asking for String class. This is something I'll try to follow up. </p> http://forums.leaflabs.com/topic.php?id=10185&page=2#post-22422 Wed, 20 Feb 2013 19:26:31 +0000 bubulindo 22422@http://forums.leaflabs.com/ <p>This is interesting... </p> <p>I missed this post I guess.<br /> I'll have a look at it when I have the time then. :)</p> <p>Maybe a way forward would be to adapt this to DMA SPI interface? </p> http://forums.leaflabs.com/topic.php?id=10185&page=2#post-22419 Wed, 20 Feb 2013 10:37:52 +0000 dinau 22419@http://forums.leaflabs.com/ <p>Hi trevorshiwnath.</p> <p>As FYI,<br /> I've already imported the Arduino Eathernet libray(for W5200,W5100) to Maple last year.<br /> <a href="https://bitbucket.org/dinau/ethernetmaple" rel="nofollow">https://bitbucket.org/dinau/ethernetmaple</a></p> <p>Please refer to this thread,<br /> <a href="http://forums.leaflabs.com/topic.php?id=1420#post-10481" rel="nofollow">http://forums.leaflabs.com/topic.php?id=1420#post-10481</a></p> <p>Regards,</p> <p>dinau </p> http://forums.leaflabs.com/topic.php?id=10185#post-22418 Wed, 20 Feb 2013 08:39:32 +0000 crenn 22418@http://forums.leaflabs.com/ <p>I've run into a small problem which is actually a small brick wall.

One of the things I've had to do while working with the new Ethernet library (not sure if the dependencies were there in previous versions) is copy a lot of files in the Arduino 'base' code that the Ethernet library relies on. Moving forward is possible going to find anything AVR specific and remove it for the moment. </p> http://forums.leaflabs.com/topic.php?id=10185#post-22381 Thu, 14 Feb 2013 22:04:25 +0000 bubulindo 22381@http://forums.leaflabs.com/ <p>As I said, I'll probably only have time and wired internet availability mid next month and even then I'll be moving in to a new house so you don't need to rush.

From what I understand from what you all have said is that I can use the ICSP for SPI communications between the Maple and the Ethernet Shield. To do this I would have to take the "Master In Slave Out(MISO)", "Master Out Slave In (MOSI)" and "Serial Clock (SCK)" pins on the Ethernet shield's ICSP port and hook them up to the SPI pins of the Maple board. As well as VCC and Ground on the ICSP port to VCC and Ground pins on the Maple of course. Is this correct?</p> <p>Also, is the Reset pin necessary as well or can I just leave it as it is?</p> <p>Thanks!</p> <p>Edit: Crenn, I saw your code with the Ethernet Shield and you mentioned it have errors in it. I'm just wondering what can your code currently do "as is" right now? </p>
