Can anyone help me to combine two different code of function?

[hoyunzerg]

I have two different code of functions and I want to combine them together to make it work together. both of code for dht11 sensor.

1. first code is for getting sensor data and update in google spreadsheet.
2. second code is for getting sensor data and display on OLED screen.

what I want is to work both functions(it's ok if both are not working at the same time. work sequentially is ok..)

----------------------------------- here is first one.

#include <WiFi.h>
#include <HTTPClient.h>

#include "DHT.h"
#define DHTPIN 27
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE); 

//---------------------------------------------------------------------
const char * ssid = "WIFI";  // type your Wifi name
const char * password = "PW";  // Type your wifi password
String GOOGLE_SCRIPT_ID = "spreadsheetinfo";  // Type your App Script id
                       

const int sendInterval = 50;

WiFiClientSecure client;


void setup() {
 pinMode(2,OUTPUT);
  dht.begin();
  Serial.begin(115200);
  delay(100);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  Serial.print("Connecting to Wi-Fi");
  while (WiFi.status() != WL_CONNECTED) {
    digitalWrite(2,LOW);
    delay(5000);
    Serial.print(".");
    digitalWrite(2,HIGH);
    delay(5000);
  }
  Serial.println("OK");
  }
void loop() {
   float h = dht.readHumidity();
   float t = dht.readTemperature();
  if (isnan(h) || isnan(t)) {
    Serial.println(F("Failed to read from DHT sensor!"));
    return;
  }

  
 write_google_sheet( "value1="+String(h)+"&value2="+String(t));

delay(1000);
 
}

///////////////////////////////////////////////
void write_google_sheet(String params) {
   HTTPClient http;
   String url="https://-+GOOGLE_SCRIPT_ID+"/exec?"+params;
   Serial.println(url);
    Serial.println("Updating Temperature & Humidity Status");
    http.begin(url.c_str());
    http.setFollowRedirects(HTTPC_STRICT_FOLLOW_REDIRECTS);
    int httpCode = http.GET();  
    Serial.print("HTTP Status Code: ");
    Serial.println(httpCode);
    
    String payload;
    if (httpCode > 0) {
        payload = http.getString();
        Serial.println("Payload: "+payload);     
    }
    http.end();
delay(600000);    // data loading time change in google speadsheet 10min

}

-----------------------------------here is second code for displaying.

#include "DHTesp.h"
#include "heltec.h"

DHTesp dht;
 
float currentTemp;
float currentHumidity;
 
void displayReadingsOnOled() {
   
  String temperatureDisplay ="Temperature: " + (String)currentTemp +  "°C";
  String humidityDisplay = "Humidity: " + (String)currentHumidity + "%";
 
  // Clear the OLED screenw
  Heltec.display->clear();
  // Prepare to display temperature
  Heltec.display->drawString(0, 0, temperatureDisplay);
  // Prepare to display humidity
  Heltec.display->drawString(0, 12, humidityDisplay);
  // Display the readings
  Heltec.display->display();
}
    
void setup()
{
 displayReadingsOnOled ;
  dht.setup(27, DHTesp::DHT11);
   
  currentTemp = dht.getTemperature();
  currentHumidity = dht.getHumidity();
 
  pinMode(LED,OUTPUT);
  digitalWrite(LED,HIGH);
 
  Heltec.begin(true /*DisplayEnable Enable*/, false /*LoRa Enable*/, false /*Serial Enable*/);
  displayReadingsOnOled();
  Serial.println("OK");
}
 
 
    
void loop()
{
  float temperature = dht.getTemperature();
  float humidity = dht.getHumidity();
 
  if (temperature != currentTemp || humidity != currentHumidity) {
    currentTemp = temperature;
    currentHumidity = humidity;
    displayReadingsOnOled();
  }
    
  delay(2000);
}

It is explained here http://www.thebox.myzen.co.uk/Tutorial/Merging_Code.html

Get rid of that socking great 2 second delay at the end of the second code. Any delay will delay both codes when merged.

If you think 2 seconds is bad, there's this one:

@hoyunzerg

    http.end();
delay(600000);    // data loading time change in google speadsheet 10min

}
