Не могу совместить два скетча, esp8266 web server

artem421443 · 7 Ноя 2021

Здравствуйте, недавно начал осваивать ESP8266 для школьного проекта, но столкнулся с некоторыми трудностями. В моей работе должны сочетаться два скетча с этих работ: https://randomnerdtutorials.com/esp32-esp8266-web-server-physical-button/ и https://randomnerdtutorials.com/esp...ure-and-humidity-web-server-with-arduino-ide/
Задача состоит в их объединении, но у меня этого не получается. Проверял по отдельности - всё работает, но совместно жить эти скетчи не хотят. Также пытался отобразить на веб странице вместе с кнопкой (первая ссылка) изображение, но тоже ничего не получалось(
Огромная благодарность тому, кто поможет, мне это очень нужно!
Мой нерабочий код:

Код:

#ifdef ESP32
  #include <WiFi.h>
  #include <AsyncTCP.h>
#else
  #include <ESP8266WiFi.h>
  #include <ESPAsyncTCP.h>
#endif
#include <ESPAsyncWebServer.h>
#include <Arduino.h>
#include <Hash.h>
#include <Adafruit_Sensor.h>
#include <DHT.h>



// Replace with your network credentials
const char* ssid = "TP-LINK_2F3896";
const char* password = "65QUMO23drag";

const char* PARAM_INPUT_1 = "state";

const int output = 2;
const int buttonPin = 4;

// Variables will change:
int ledState = LOW;          // the current state of the output pin
int buttonState;             // the current reading from the input pin
int lastButtonState = LOW;   // the previous reading from the input pin

// the following variables are unsigned longs because the time, measured in
// milliseconds, will quickly become a bigger number than can be stored in an int.
unsigned long lastDebounceTime = 0;  // the last time the output pin was toggled
unsigned long debounceDelay = 50;    // the debounce time; increase if the output flickers


#define DHTPIN 5     // Digital pin connected to the DHT sensor

// Uncomment the type of sensor in use:
#define DHTTYPE    DHT11     // DHT 11
//#define DHTTYPE    DHT22     // DHT 22 (AM2302)
//#define DHTTYPE    DHT21     // DHT 21 (AM2301)

DHT dht(DHTPIN, DHTTYPE);

// current temperature & humidity, updated in loop()
float t = 0.0;
float h = 0.0;



// Create AsyncWebServer object on port 80
AsyncWebServer server(80);

unsigned long previousMillis = 0;    // will store last time DHT was updated

// Updates DHT readings every 10 seconds
const long interval = 10000;
