It's looks like the Arduino Ethernet shield cannot be used on the ligthuino5, is there a way that it can be solved?

Hi Jeremy,
 
Thanks for producing this table!
 
Pin 0 and 1 are the serial port on the Arduino, as well as being digital
IOs. This is important because if you use them as digital IOs then of
course you can't do Serial.print()!
The Lightuino does not use them for the serial port that goes through the
USB (accessed via Usb.print()). So you can actually use them as another
serial port or as digital IOs
 
Pins 10-13 are the USB, through the "SPI" protocol. So you can actually
share most of these pins with other SPI devices...
 
The Lightuino also has 2 addtl pins, A6 and A7, which are analog input only
(A0-A5 can be analog or digital IO). A7 is used as the ambient light
sensor.
 
 
I'm looking forward to reading your blog but as it is in french its going to
take more time and effort then I have at this moment (midnight)! :-)
 
Cheers!
Andrew

I tried this, but it doesn't work

It may be an issue with the USB conflicting with the ethernet over the SPI bus.  If so, you can try a "big hammer" by putting the USB into reset.  Of course, then you won't get USB serial... but you could still use the TX, RX serial if you have an FTDI cable.  But anyway you have ethernet so why do you need USB :-)

To put the USB chip into reset, you'll see an unpopulated header called CY_PRG_MINI above the USB connector.  The rightmost hole is labelled "reset".  Solder a jumper wire to this and then plug it into the 5v "arduino" header.  That will hold the chip in reset.  You'll know it is working because the blue LED will go dark but every time you unplug the jumper from the 5v header it will flash blue a few times.

I'll try this tomorrow, and other stuff to see if I can get them both working together.


Cheers!
Andrew
