Кстати в оф сайте есть такая информация:
Спойлер
Network port control pin description
Network port interface | ESP32-S3-ETH GPIO
MISO | GPIO12
MOSI | GPIO11
SCLK | GPIO13
CS | GPIO14
RST | GPIO9
INT | GPIO10
я прозвонил эти контакты, и все в норме как по схеме. А еще на оф сайте я нашел скетч с ETH, но он у меня не работает. В скетче я нашел переменную, значение которой я нигде не могу найти… и интересно что какой то пин подает 5V(3.3V), что за пин я тоже так и не понял… Может для того чтобы W5500 заработала, нужно питание подать на какой то пин? в w5500 есть пин который называется INT, что делает этот пин, немного не понял… но вдруг для того чтобы модуль заработал, нужно именно туда питание подать?
В скетче
#ifdef ETH_POWER_PIN
pinMode(ETH_POWER_PIN, OUTPUT);
digitalWrite(ETH_POWER_PIN, HIGH);
#endif
попытался вывести ее, выдает ошибку
Так пытаюсь
void setup()
{
Serial.begin(115200);
Serial.setDebugOutput(true);
Serial.println();
Serial.println(ETH_POWER_PIN);
pinMode(CAM_ENABLE, OUTPUT); // Configure CAM_ENABLE pin as output
digitalWrite(CAM_ENABLE, LOW); // Ensure CAM_ENABLE is off at startup
WiFi.onEvent(WiFiEvent);
#ifdef ETH_POWER_PIN
pinMode(ETH_POWER_PIN, OUTPUT);
digitalWrite(ETH_POWER_PIN, HIGH);
#endif
Такая ошибка
error: ‘ETH_POWER_PIN’ was not declared in this scope; did you mean ‘ETH_MOSI_PIN’?
96 | Serial.println(ETH_POWER_PIN);
Весь скетч

* @note Only support T-ETH-Lite-ESP32S3, need external camera shield to combine
* @Steps
* 1. Don’t plug in the camera, flash sketch, and plug in the network cable
* 2. After startup, check the connected IP address through the Serial monitor and record the IP address.
* 3. Turn off the power and plug in the camera module
* 4. After powering on, open a browser on a computer on the same LAN and enter the URL you just recorded to access the camera.
