MFRC522, Ethernet/Serial, Nano/Uno/Mega
Steve,
OK, so I tested this latest version using a Mega and 1 reader, with no shield since I don't have one at home right now to use. Uploaded sketch, open Serial monitor, get Ethernet not connect or no connection available message and also get Reader A detected on pin X. Reads tags no problem. Moved my single reader to the next set of SS/RST pins, reset the Mega, same result, but now with Reader B. Repeated this process for all 8 SS/RST pin pairs/ReaderIDs. Debugging messages displaying correctly and Serial output is correct for all 8 readers. LED blinks once for me since only 1 reader connected to any SS/RST pin pair. Will hopefully be able to test this Mega and an Uno tomorrow with the attached Ethernet shield, but there is no reason it shouldn't work as expected.?
Tom
