Problem With Ethernet Port - rferreras - 08-06-2024
I have the following Arduino code and I can not get my A32 Pro to connect to the network and take IP, in the port if I see that there is connection but I can not get it to take an IP address from the DHCP of my network.
Code:
#ifndef ETH_PHY_TYPE
#define ETH_PHY_TYPE ETH_PHY_LAN8720
#define ETH_PHY_ADDR 0
#define ETH_PHY_MDC 23
#define ETH_PHY_MDIO 18
#define ETH_PHY_POWER -1
#define ETH_CLK_MODE ETH_CLOCK_GPIO0_IN
#endif
#include <ETH.h>
#include "Arduino.h"
#include "PCF8574.h"
#include <Wire.h>
#include <WiFi.h>
#include <Ethernet.h>
#include <SPI.h>
#include <PubSubClient.h>
#include <ArduinoJson.h>
#include "esp_system.h"
#include "esp_task_wdt.h"
EthernetClient ethClient;
PubSubClient client(ethClient);
void setup() {
Serial.begin(115200);
ETH.begin();
while (Ethernet.localIP() == INADDR_NONE) {
Serial.println("Esperando dirección IP...");
delay(1000); // Esperar 1 segundo antes de verificar nuevamente
}
while (ETH.localIP() == INADDR_NONE) {
Serial.println("Esperando dirección IP...");
delay(1000); // Esperar 1 segundo antes de verificar nuevamente
}
while (!ETH.linkUp()) {
Serial.print(".");
delay(1000);
}
Serial.println("");
Serial.println("Ethernet conectado");

A32 pro not use by LAN8720, it use by w5500 chip.

this is arduino demo code for w5500 work with UDP
RE: Problem With Ethernet Port - rferreras - 08-07-2024
In the end you can solve it using the following code, I share it in case someone needs it.
Code:
#include "Arduino.h"
#include "PCF8574.h"
#include <Wire.h>
#include <WiFi.h>
#include <SPI.h>
#include <Ethernet.h>
#include <PubSubClient.h>
#include <ArduinoJson.h>
#include "esp_system.h"
#include "esp_task_wdt.h"
#include <U8g2lib.h>
#define INT_GPIO 41
#define MISO_GPIO 40
#define MOSI_GPIO 44
#define SCK_GPIO 4
#define CS_GPIO 39
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
EthernetClient ethClient;
PubSubClient client(ethClient);
void(* resetFunc) (void) = 0;
void setup() {
while (!Serial && (millis() < 5000));
delay(500);
// Configurar SPI con los pines especificados
SPI.begin(SCK_GPIO, MISO_GPIO, MOSI_GPIO, CS_GPIO);
// Inicializar la conexión Ethernet
Ethernet.init(CS_GPIO); // Inicializar con el pin CS
Ethernet.begin(mac);
// Esperar a que se asigne una dirección IP
if (Ethernet.hardwareStatus() == EthernetNoHardware) {
Serial.println("Ethernet shield was not found.");
while (true) {
delay(1); // No continuar
}
}
if (Ethernet.linkStatus() == LinkOFF) {
Serial.println("Ethernet cable is not connected.");
} else {
Serial.print("Ethernet IP: ");
Serial.println(Ethernet.localIP());
}
//Inicializar el Watchdog Timer
esp_task_wdt_config_t config;
config.timeout_ms = 30000; // Establece el tiempo de espera a 30 segundos
esp_task_wdt_init(&config);
esp_task_wdt_add(NULL);
}
void loop() {
esp_task_wdt_reset();
}Now my problem is trying to enable the Watchdog, it is not respecting the function esp_task_wdt_reset() since I am constantly resetting the card, if anyone has any example of Watchdog on the esp32 S3 I would appreciate it.
