Project Description
This library is to facilitate your usage of W5100S-EVB-Pico board with the onboard Wiznet W5100S chip, using [**Arduino-mbed RP2040** core](https://github.com/arduino/ArduinoCore-mbed)
In case you are looking for an event driven approach of receiving Ethernet data/status, rather than the traditional polling method, this library may be one of choices for you.
Events to be dispatched to: void (*EthernetEventCallback)(uint8_t ir, uint8_t ir2, uint8_t slir);
1. Interrupt Register (IR)
EthernetEventApi::Ir::CONFLICT
EthernetEventApi::Ir::UNREACH
EthernetEventApi::Ir::PPPTERM
note: NO Sn_INT events in EthernetEventCallback. User should use Sn_IR in SocketEventCallback
2. Interrupt Register 2 (IR2)
EthernetEventApi::Ir2::WOL
3. SOCKET-less Interrupt Register (SLIR)
EthernetEventApi::Slir::TIMEOUT
EthernetEventApi::Slir::ARP
EthernetEventApi::Slir::PING
Events to be dispatched to: void (*SocketEventCallback)(uint8_t sn_ir);
1. SOCKET n Interrupt Register (Sn_IR)
SnIR::SEND_OK
SnIR::TIMEOUT
SnIR::RECV
SnIR::DISCON
SnIR::CON

#### Using [EventEthernet](https://github.com/teamprof/arduino-eventethernet)
############################################################################
#include <EventEthernet.h>
void setup() {
Ethernet.init(17, 21); // W5100S-EVB-Pico: nCS pin = GPIO17, Intn pin = GPIO21
while (Ethernet.begin(mac, ir, ir2, slir, onEthernetEvent) == 0)
{
LOG_DEBUG("Failed to configure Ethernet using DHCP");
delay(1000);
}
}

#### Using original [WIZnet-ArduinoEthernet](https://github.com/WIZnet-ArduinoEthernet/Ethernet)
############################################################################
#include <Ethernet.h>
//#include <EventEthernet.h> // note: you can use EventEthernet lib on existing code with polling method
void setup() {
Ethernet.init(17); // W5100S-EVB-Pico: nCS pin = GPIO17
while (Ethernet.begin(mac) == 0)

Hi teamprof,
I’m Ron from WIZnet HK. Could I post your article to our WIZnet HK instagram account?
BTW, do you have a instagram account that I could tag you?
Best Regards,
Ron
