Link Status
|
|
This sketch prints the ethernet link status. When the
|
|
ethernet cable is connected the link status should go to "ON".
|
|
NOTE: Only WizNet W5200 and W5500 are capable of reporting
|
|
the link status. W5100 will report "Unknown".
|
|
Hardware:
|
|
- Ethernet shield or equivalent board/shield with WizNet 5200/5500
