ethernet

[parabyte]

I just wish to confirm that ethernet.h library i cannot get to work with the esp32, crashes your code in a non stop bootloop.

same goes for there example code they ship.

The ethernet library ETH.H that espressif ships works perfectly with your code.

this is working code using your library.

#include <SPI.h>
#include "AudioTools.h"
#include "SnapClient.h"
#include <ETH.h>

#define ETH_PHY_TYPE ETH_PHY_W5500
#define ETH_PHY_ADDR 1
#define ETH_PHY_CS 5
#define ETH_PHY_IRQ 22
#define ETH_PHY_RST 21

// SPI pins
#define ETH_SPI_SCK 18
#define ETH_SPI_MISO 23

SnapClient client(ethernet, out, pcm);

static bool eth_connected = false;

void connectEthernet() {

// Serial.println("Starting ETHERNET connection...");
ETH.begin(ETH_PHY_TYPE, ETH_PHY_ADDR, ETH_PHY_CS, ETH_PHY_IRQ, ETH_PHY_RST, SPI);
ETH.setHostname(CONFIG_SNAPCAST_CLIENT_NAME);

// wait for link
while(!ETH.linkUp()){
delay(100);
}

Serial.print("Ethernet IP is: ");
Serial.println(ethernet.localIP());

}

void setup() {
//Serial.begin(115200);
client.setWiFi(false);
SPI.begin(ETH_SPI_SCK, ETH_SPI_MISO, ETH_SPI_MOSI);
connectEthernet();

auto cfg = out.defaultConfig(TX_MODE);
cfg.pin_bck = 27;
cfg.pin_ws = 26;
cfg.pin_data = 25;

cfg.use_apll = true;  // Use the audio PLL for low-jitter
cfg.is_master = true;  // Set to master mode
out.begin(cfg);

// client.begin(synch);
client.setServerIP(IPAddress(192, 168, 10, 103));

sorry about the formatting # define CONFIG_SNAPCAST_BUFF_LEN 2048
is fine before i cut and paste the code here

Here are the instructions for pasting code:

I am converting this to a discussion since this is not a bug in my code but rather an issue with your installed version or your specific board.

What ESP32 Arduino core version are you using ?

Espressif 3.02

im using this board, https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display

iv removed the dac ic and have put a header in its place so i can interface with external i2s device. and i am using its sdcard interface for ethernet
