Topic: Connecting an Ethernet PHY to Arduino Due (Read 45 times) previous topic - next topic


I connected Taijiuino with EPHY DP83848 but no communication. I will be revising the phy files, pin configuration and wires. I hope to bring good news soon. Here a picture of my mess!.


This is one thread I am really interested in.  Ethernet on the DUE without sacrificing so many i/o pins or fitting a shield.
Quiero una vida simple en Mexico...nada mas.


Hi Palliser

I'm also interested in this, I'll likely go and make my own board (not a shield )to add onto a TAIJIUINO so I can pick up the additional pads, I'll design this board with 802.3af POE hence why I'll design my board around components that have been proved to work 1st ;)
I wish you luck...  I did wonder if the breadboard wiring may be causing an issue with its failure; have you tried to shorten the wiring at all ??



Hello Graham,

I am happy you are interested in this project. I still working on the modified Ethernet MAC library. As you mentioned, I had to get rid off the breadboard to avoid wiring issues. Here a picture of what I have so far with less connections between the external Ethernet PHY DP83848 and a Taijiuino, although I am planning to use a DM9161 Phy when coming in from Russia next week. It could be also great to see your POE one of these days. One of my future goals is the implementation of a Webserver example, but for that, I have to wait a little longer. Regards!


Hello Palliser

My; that looks a lot neater, and hopefully stop any gremlins with wire lengths.
It will be interesting when you receive the DM9161, is this mounted on a carrier with the jack/magnetic's similar to the DP83848 board ?

The POE is very easy to achieve with suitable Jack socket, as similar to the Arduino Ethernet, and a ready built POE module can then be soldered in
these can range in voltage from 3.3V upwards so can be selected to give the voltage that's required and additional Voltage regulators used for lower voltages if needed.
some such as the silverline range can have there outputs modified, the usual 12V from the 9012-S POE module is reprogrammed with a shorting link to only supply 9V so not to overheat the fixed 5V regulator on most of the Arduino boards.

I'll keep and eye open for developments and wish you success
