Tnx smiley

I'm not familiar with (this or) other PHY modules, I just liked this one because It has everything soldered so there is only the software part to do.
I'm a developer so software is easier to me than pcb design...

I have found this DP83848 PHY ethernet board which should be very simple to set up, because it's kind of all in one. On the header are all the signals neded for RMII.

The cheapest price that I have found is on ebay for 15.99$:

Since I'm not really experienced in pcb design I'll go with this for a start and perhaps later make my own pcb design...

Today I have ordered some DM9161 from ebay so I'll be able to contribute to the progress on arduino due ethernet port. smiley-wink

Some time ago I wrote tutorial on: arduino + ethenet shield + node.js for udp streaming http://frenki.net/2012/10/remote-logging-with-arduino-and-node-js/
I would like to use the same technique (but faster) to convert DUE into simple oscilloscope and logic analyser. (But this time without W5100 ethernet shield)

Do you think we could use this cheap Enc28j60 boards, which are on ebay for 4$ instead of using AS-DM9161?



For connection to SAM3X8E ethernet pins I would go with pogo-pins mounted on the bottom of DIY shield for DUE.

Thank you. I will fix it.

Just one more thing...
More advanced users could leave out byte to int conversion in node.js code:

if you change:
fs.appendFile('mydata.txt', msg.readUInt16LE(0) + crlf, encoding='utf8');//write the value to file and add CRLF for line break

into:

fs.appendFile('mydata.txt', msg, encoding='utf8');

You will be saving bytes in ascii characters and logging file will be much smaller...
One of my next projects will be to use arduino as an oscilloscope to send a lot of data quickly over UDP to browser.
In that case udp packets will be 512 bytes long instead of 2 bytes as in this example.

Hi guys.

I've made a tutorial on how to use arduino with ethernet shield and Node.js server to make remote logging.

On Arduino I have a sketch which reads from analog port and sends udp packets to desired ip and port.
On the other side I have a computer with Node.js and udp server to listen to udp traffic.



I would really like to hear from you if tutorial is ok to improve on next. smiley
