Hi all

Please assist me in combining the following sketches. I want the results to be displayed on the 16x2 LCD.

First Sketch

#include <LiquidCrystal.h>
#include <SimpleDHT.h>
int pinDHT11 = 7;
SimpleDHT11 dht11;
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
void setup() {
Serial.begin(9600);
lcd.begin(16, 2);
}
void loop() {
Serial.println("=================================");
Serial.println("DHT11 readings...");
byte temperature = 0;
byte humidity = 0;
int err = SimpleDHTErrSuccess;
if ((err = dht11.read(pinDHT11, &temperature, &humidity, NULL)) != SimpleDHTErrSuccess) {
Serial.print("No reading, err="); Serial.println(err); delay(1000);
return;
}
Serial.print("Readings: ");
Serial.print((int)temperature); Serial.print(" Celcius, ");
Serial.print((int)humidity); Serial.println(" %");
lcd.clear();
lcd.setCursor(0,0);
lcd.print("Temp: ");
lcd.print((int)temperature);
lcd.setCursor(0,1);
lcd.print("Humidity(%): ");
lcd.print((int)humidity);
delay(750);
}

Secong Sketch

#include <Wire.h>
#include <SPI.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BMP280.h>

#define BMP_SCK 13
#define BMP_MISO 12
#define BMP_MOSI 11
#define BMP_CS 10

//Adafruit_BMP280 bme; // I2C
//Adafruit_BMP280 bme(BMP_CS); // hardware SPI
Adafruit_BMP280 bme(BMP_CS, BMP_MOSI, BMP_MISO, BMP_SCK);

void setup() {
Serial.begin(9600);
Serial.println(F("BMP280 test"));

if (!bme.begin()) {
Serial.println("Could not find a valid BMP280 sensor, check wiring!");
while (1);
}
}
void loop() {
Serial.print("Temperature = ");
Serial.print(bme.readTemperature());
Serial.println(" *C");

Serial.print("Pressure = ");
Serial.print(bme.readPressure());
Serial.println(" Pa");

Serial.print("Approx altitude = ");
Serial.print(bme.readAltitude(1013.25)); // this should be adjusted to your local forcase
Serial.println(" m");
Serial.println();
delay(2000);
}

I've done the first part. It compiles. Now you can do the rest.

void setup()
{
  setup1();
  setup2();
}


void loop()
{
  loop1();
  loop2();
}


#include <LiquidCrystal.h>
#include <SimpleDHT.h>
int pinDHT11 = 7;
SimpleDHT11 dht11;
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);


void setup1()
{
  Serial.begin(9600);
  lcd.begin(16, 2);
}


void loop1()
{
  Serial.println("=================================");
  Serial.println("DHT11 readings...");
  byte temperature = 0;
  byte humidity = 0;
  int err = SimpleDHTErrSuccess;
  if ((err = dht11.read(pinDHT11, &temperature, &humidity, NULL)) != SimpleDHTErrSuccess)
  {
    Serial.print("No reading, err="); Serial.println(err); delay(1000);
    return;
  }
  Serial.print("Readings: ");
  Serial.print((int)temperature); Serial.print(" Celcius, ");
  Serial.print((int)humidity); Serial.println(" %");
  lcd.clear();
  lcd.setCursor(0, 0);
  lcd.print("Temp: ");
  lcd.print((int)temperature);
  lcd.setCursor(0, 1);
  lcd.print("Humidity(%): ");
  lcd.print((int)humidity);
  delay(750);
}
