USR-ES1 module
I have it connected to:
D13 on CLK,
D12 on MISO,
D11 on MOSI,
D10 on ss.
But using GitHub - davenardella/Ethernet_SPI2: Arduino GIGA R1 Dual Ethernet project
just to test it with the ethernet.h library i keep getting the response:
Ethernet adapters were not found on both SPI interfaces. Sorry, can't run without hardware.
Would you perhaps know the solution?

I also tried the following code using the Ethernet2 library:
#include <SPI.h>
#include <Ethernet2.h> // Use Ethernet2 for W5500
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; // Unique MAC address
void setup() {
// Start serial communication
Serial.begin(115200);
// Ensure the serial port is open (for boards like Leonardo)
while (!Serial) {
;
}
// Initialize SPI1 for the W5500
SPI1.begin();
// Manually specify the chip select (SS) pin
Ethernet.init(10); // Adjust pin according to your wiring (e.g., 10)
// Add a small delay before initializing Ethernet to ensure the module is ready
delay(1000); // 1 second delay to allow W5500 to power up and stabilize
// Start the Ethernet connection using DHCP
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// Stop the program if DHCP fails
while (true);
}
// Print the obtained IP address
Serial.print("My IP address: ");
for (byte thisByte = 0; thisByte < 4; thisByte++) {
Serial.print(Ethernet.localIP()[thisByte], DEC);
if (thisByte < 3) {
Serial.print(".");
}
}
Serial.println();
}
void loop() {
// Nothing in the loop for now
}
This gives a Failed to configure Ethernet using DHCP error.
