Has anyone on this forum got an internet shield that actually works with shieldbuddy i am porting an app from mega2560
that requires network access and so far i cannot get any network cards to work.
Just wondering at this point if i have wasted money and time on this shieldbuddy card i see numerous questions about
network on these forums but little in regard to solid answers to getting a reliable network working in this unit.
If you have a network shield reliably working on the shieldbuddy can you post detailed information on what CS pins you are using and what library you are using to make it happen.
In my case i need UDP access and my existing application uses the SQL connector library to talk to a remote SQL database. The app works just fine with W5100 shield on the mega2560 i was truly hoping to port this for the
multiprocessor support on the TC275 but i am losing hope of getting anything running on the card seems like a good idea but without a good implementation that works.
Just does not seem to be a straight answer on this anywhere in the forum.
My apologies if my frustration with the shieldbuddy implementation is showing its advertised as mega compatible but it seems far from that after hands on experience with it.

The Shieldbuddy has been tested with the official Arduino Ethernet shield R3 that uses the W5100. It also works with the Ethernet shield2 which uses the W5500.
Which Shields have you tried?

Hi,
I have the same problem as OP, Impossible to detect the ethernet shield (original Arduino Ethernet Shield 2 [WZ5500])
Is there something i'm missing ?
Here is my code just in case :
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xA8, 0x61, 0x0A, 0xAE, 0x7C, 0x0B};
void setup() {
// Open serial communications and wait for port to open:
SerialASC.begin(9600);
Ethernet.begin(mac);
SerialASC.print("server is at ");
SerialASC.println(Ethernet.localIP());
}
void loop() {
switch (Ethernet.linkStatus()) {
case Unknown:
SerialASC.println("Unknown");
break;
case LinkON:
SerialASC.println("ON");
break;
case LinkOFF:
SerialASC.println("OFF");
break;
}
delay(1000);
}

This has been tested using an Ethernet Shield2 with pin10 as the chipselect for the W5500 and pin4 for the SD card. The SPI is via the 6-way pin header.

This definitely works! You might need to change the IP address though to suit your local network.

Good night Admin,
what version of ethernet2 library you use?
my vesion ethernet2 1.0.4 compile without error but when I restart the board, reset led in TC275 ShieldBuddy start to blink
and don´t work
This version of ethernet2 works on Uno, Mega and Due
thanks,
Iban
