Esp32 with w5500 - slow speed

Other Hardware 3rd Party Boards

Hello

I am currently testing my esp32 with a w5500 Ethernet shield:

I tested the connection with iperf and this is what I got:

image839×252 7.39 KB

Actually it should come out at least 10MBits. In this post someone has also only managed to get 3MBits at first and then further down with the w5500 over 10MBits:

How do I manage that too?

This is my code for the iperf on the ESP32 (SPI pins are the default ones i used):

void loop() {
  byte buf[1024];
  EthernetClient client = server.available();
  if (client) {
    Serial.println("Here is a new client for checking Arduino performance");
    while (client.connected()) {
      if (client.available()) client.read(buf, 1024);
    }
    client.stop();
    Serial.println("client disconnected");
  }
}

That is my Full code:

#include <SPI.h>
#include <Ethernet.h>


// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

// Set the static IP address to use if the DHCP fails to assign
#define MYIPADDR 192,168,2,28
#define MYIPMASK 255,255,255,0
#define MYDNS 192,168,2,1
#define MYGW 192,168,2,1

//EthernetClient client;
EthernetServer server(5001);
unsigned long startTime;

void setup() {
  Serial.begin(115200);
  delay(1000);
  Serial.println("Begin Ethernet");


  Serial.println("CS PIN 5");
  Serial.println("Hat geklappt");



  server.begin();
  // You can use Ethernet.init(pin) to configure the CS pin
  //Ethernet.init(10);  // Most Arduino shields
  Ethernet.init(5); // Ändere die CS-Pin-Nummer entsprechend deiner Verdrahtung
  //Ethernet.init(20);  // Teensy++ 2.0
  //Ethernet.init(15);  // ESP8266 with Adafruit FeatherWing Ethernet
  //Ethernet.init(33);  // ESP32 with Adafruit FeatherWing Ethernet

  if (Ethernet.begin(mac)) { // Dynamic IP setup
    Serial.println("DHCP OK!");
  }
  else {
    Serial.println("Failed to configure Ethernet using DHCP");
    // Check for Ethernet hardware present
    if (Ethernet.hardwareStatus() == EthernetNoHardware) {
      Serial.println("Ethernet shield was not found.  Sorry, can't run without hardware. :(");
      while (true) {
        delay(1); // do nothing, no point running without Ethernet hardware
      }
    }
    if (Ethernet.linkStatus() == LinkOFF) {
      Serial.println("Ethernet cable is not connected.");
    }

    IPAddress ip(MYIPADDR);
    IPAddress dns(MYDNS);
    IPAddress gw(MYGW);
    IPAddress sn(MYIPMASK);
    Ethernet.begin(mac, ip, dns, gw, sn);
    Serial.println("STATIC OK!");
  }
  delay(5000);


  Serial.print("Local IP : ");
  Serial.println(Ethernet.localIP());
  Serial.print("Subnet Mask : ");
  Serial.println(Ethernet.subnetMask());
  Serial.print("Gateway IP : ");
  Serial.println(Ethernet.gatewayIP());
  Serial.print("DNS Server : ");
  Serial.println(Ethernet.dnsServerIP());

  Serial.println("Ethernet Successfully Initialized");

}


void loop() {
  byte buf[1024];
  EthernetClient client = server.available();
  if (client) {
    Serial.println("Here is a new client for checking Arduino performance");
    while (client.connected()) {
      if (client.available()) client.read(buf, 1024);
    }
    client.stop();
    Serial.println("client disconnected");
  }
}

i got
MISO,MOSI,SCK,CS
connected

i think It's because i need to set it to 80Mhz but i dont know
