Platfomio y VScode error de compilacion con ESP32

Adrian_E · April 5, 2021, 9:07pm

estoy usandoVS code y platformio, encontre un codigo que conecta con el reloj en la web, con el ide de arduino funciona bien, pero en vs code platformio me tira este error, estoy usando un ESP32
este es el codigo

#include <Arduino.h>
#include <WiFi.h>
#include "time.h"

const char* ssid     = "MI_USUARIO";
const char* password = "MI_PASS";

const char* ntpServer = "pool.ntp.org";
const long  gmtOffset_sec = 0;
const int   daylightOffset_sec = 3600;

void setup(){
  Serial.begin(115200);

  // Connect to Wi-Fi
  Serial.print("Connecting to ");
  Serial.println(ssid);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected.");
  
  // Init and get the time
  configTime(gmtOffset_sec, daylightOffset_sec, ntpServer);
  printLocalTime();

  //disconnect WiFi as it's no longer needed
  WiFi.disconnect(true);
  WiFi.mode(WIFI_OFF);
}

void loop(){
  delay(3000);
  printLocalTime();
}

void printLocalTime(){
  struct tm timeinfo;
  if(!getLocalTime(&timeinfo)){
    Serial.println("Failed to obtain time");
    return;
  }
  Serial.println(&timeinfo, "%A, %B %d %Y %H:%M:%S");
  Serial.print("Day of week: ");
  Serial.println(&timeinfo, "%A");
  Serial.print("Month: ");
  Serial.println(&timeinfo, "%B");
  Serial.print("Day of Month: ");
  Serial.println(&timeinfo, "%d");
  Serial.print("Year: ");
  Serial.println(&timeinfo, "%Y");
  Serial.print("Hour: ");
  Serial.println(&timeinfo, "%H");
  Serial.print("Hour (12 hour format): ");
  Serial.println(&timeinfo, "%I");
  Serial.print("Minute: ");
  Serial.println(&timeinfo, "%M");
  Serial.print("Second: ");
  Serial.println(&timeinfo, "%S");

  Serial.println("Time variables");
  char timeHour[3];
  strftime(timeHour,3, "%H", &timeinfo);
  Serial.println(timeHour);
  char timeWeekDay[10];
  strftime(timeWeekDay,10, "%A", &timeinfo);
  Serial.println(timeWeekDay);
  Serial.println();
}

este es el error

Hola, el primer error que puedo observar es que la funcion printLocalTime debe ir antes del setup, en el id de arduino no importa donde lo pongas pero en platformio si, si quieres saber mas busca funciones prototipo ya que en C++ es obligatorio declarar una función antes de ser usada.

#include <Arduino.h>
#include <WiFi.h>
#include "time.h"

const char* ssid     = "MI_USUARIO";
const char* password = "MI_PASS";

const char* ntpServer = "pool.ntp.org";
const long  gmtOffset_sec = 0;
const int   daylightOffset_sec = 3600;

void printLocalTime(); // DECLARACION DE FUNCIONES PROTOTIPO

void setup(){
  Serial.begin(115200);

  // Connect to Wi-Fi
  Serial.print("Connecting to ");
  Serial.println(ssid);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected.");
 
  // Init and get the time
  configTime(gmtOffset_sec, daylightOffset_sec, ntpServer);
  printLocalTime();

  //disconnect WiFi as it's no longer needed
  WiFi.disconnect(true);
  WiFi.mode(WIFI_OFF);
}

void loop(){
  delay(3000);
  printLocalTime();
}

void printLocalTime(){
  struct tm timeinfo;
  if(!getLocalTime(&timeinfo)){
    Serial.println("Failed to obtain time");
    return;
  }
  Serial.println(&timeinfo, "%A, %B %d %Y %H:%M:%S");
  Serial.print("Day of week: ");
  Serial.println(&timeinfo, "%A");
  Serial.print("Month: ");
  Serial.println(&timeinfo, "%B");
  Serial.print("Day of Month: ");
  Serial.println(&timeinfo, "%d");
  Serial.print("Year: ");
  Serial.println(&timeinfo, "%Y");
  Serial.print("Hour: ");
  Serial.println(&timeinfo, "%H");
  Serial.print("Hour (12 hour format): ");
  Serial.println(&timeinfo, "%I");
  Serial.print("Minute: ");
  Serial.println(&timeinfo, "%M");
  Serial.print("Second: ");
  Serial.println(&timeinfo, "%S");

  Serial.println("Time variables");
  char timeHour[3];
  strftime(timeHour,3, "%H", &timeinfo);
  Serial.println(timeHour);
  char timeWeekDay[10];
  strftime(timeWeekDay,10, "%A", &timeinfo);
  Serial.println(timeWeekDay);
  Serial.println();
}

si declaro la funcion como debe ser en platformio antes del setup(), me salen estos errores

Surbyte, te consulto comente esta linea

//#include "time.h"

y comenzo a funcionar lo mismo hice en el ide de arduino y tambien sigue funcionando, la pregunta es ¿la libreria time.h tambien es llamada internamente por la libreria arduino.h, o en cada package de cada placa? por eso lo del error en vs code con platformio?

Surbyte · April 11, 2021, 4:29am

No te comprendo, si declaras qué? Yo he tomado tu códgio inicial (del primer post) y en ese tu decìas que no funcionaba y a mi si.
Què es lo que esta o debe estar diferente?
