I have been unable to get he SD card to work and almost sure it is defective. The Ethernet port does work.
I have already tried a couple of 2GB cards. I have tried the regular SD library. I have tried examples from different libraries. I have also tried the library below:
http://wiki.seeedstudio.com/W5500_Ethernet_Shield_v1.0/
I have tried that shield with 3 different Arduino boards. Same problem. SD card error from the software "initialization failed!".
- Code: Select all | TOGGLE FULL SIZE
if (!SD.begin(4))
{
SerialASC.println("initialization failed!");
return;
}
else
{
SerialASC.println("SD initialization D O N E.");
}
I have other less-expensive shields, both 5100 and 5500-based and they all work with SD cards.
