W5500

[particlerain]

Hi Yves,

i already tried your code with lan8720 and it works fine for 16 universes.
Now i need to use the W5500 because i have 4 of them laying arund. But somehow am not able to modifiy youre cpp so that it lstens for the W5500 UDP packets for Artnet. Have you tried with W5500 yet? If yes can you share your modified code for it?

Hi, I'm also having problems with the W5500 module. The ESP32 keeps rebooting when I try to listen to port 6454.

Hello
can you share the code ?

Hello, Yeah same issue, shame as this performs excellantly on Wifi, but I need stability of Wired connection.
I get a backtrace error as soon as the artnet.listen gets called. Maybe missing the UDP prototocol, or relying on lwip or some other function in the library?

`
#define UNIVERSE_SIZE_IN_CHANNEL (170 * 3)
#define LEDS_PER_PIN 340
#define CHANNELS_PER_PIN (LEDS_PER_PIN *3)

#include <FastLED.h>
#include "Arduino.h"
#include <Ethernet.h>
#include "WiFi.h"
#include "artnetESP32V2.h"

#define LEDPin8 32
#define WIZ_CSPin 5

// FastLED
#define NUM_LEDS 340
CRGB leds[8][NUM_LEDS];

artnetESP32V2 artnet = artnetESP32V2();

Ethernet.init( WIZ_CSPin );

// Setup ###############################################################################
void setup() {
Serial.begin(2000000);
if (Ethernet.begin(mac)) { // Dynamic IP setup
Serial.println("DHCP OK!");
}else{
Serial.println("Failed to configure Ethernet using DHCP");
Ethernet.begin(mac, ip);
Serial.println("STATIC OK!");
}

Serial.println("Ethernet Successfully Initialized");

artnet.addSubArtnet(0 ,CHANNELS_PER_PIN, UNIVERSE_SIZE_IN_CHANNEL, &callbackfunction );  

if(artnet.listen(6454)) { // This function creates REBOOT !!!!!!!!!
  if (useEthernet){
    Serial.print("Ethernet Listening on IP: ");
    Serial.println(Ethernet.localIP());
  }

}
}

SOLVED - You posted an example of fixing the same issue (not using Arduino Ethernet lib) in your V2 lib. I had same issue, so I suspect it is the same fix by using this other WIZ5500 specific library.

Hi, i'm kinda new to the whole uc world, could you share the code you used to get the LAN8720 running? since i'm having an hard time understanding how it all works without examples?
