This library is a modified version of the standard Arduino Ethernet library, specifically adapted for the "W5500-Ether" add-on board for Spresense.
Most features are based on the original library. There are three differences from the original Ethernet library.
1: change from
#include <Ethernet.h>
to
#include <EthernetSP.h>
2: At the setup(), insert the following command according to the reset jumper setting:
When SJ1 is shorted at 1-2, use:
W5500ETH_reset(SJ1_12);
When SJ1 is shorted at 2-3, use:
W5500ETH_reset(SJ1_23);
3: Insert the following command according to the SPI-SS jumper setting:
When SJ2 is shorted at 1-2, use:
Ethernet.init(SJ2_12);
When SJ2 is shorted at 2-3, use:
//Ethernet.init(); // Do nothing.
Other than that, it is the same as the original library.
This library is based on the original Ethernet library provided by Arduino. You can find the original library at the following location:
Please refer to the original library for more details about its usage and functionalities.
