HI, I'm trying to implement uRTClib and RTClib together as i am using the TM1673 with the DS3231(with temp), im also tying to use the temp variable in with the DS3231, the code is as following:

#include "Arduino.h"
#include "uRTCLib.h"

// uRTCLib rtc;
uRTCLib rtc(0x68);

char daysOfTheWeek[7][12] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};

void setup() {
  Serial.begin(9600);
  delay(3000); // wait for console opening

  URTCLIB_WIRE.begin();

  // Comment out below line once you set the date & time.
  // Following line sets the RTC with an explicit date & time
  // for example to set January 13 2022 at 12:56 you would call:
   rtc.set(0, 56, 12, 5, 13, 1, 22);
  // rtc.set(second, minute, hour, dayOfWeek, dayOfMonth, month, year)
  // set day of week (1=Sunday, 7=Saturday)
}

void loop() {
  rtc.refresh();

  Serial.print("Current Date & Time: ");
  Serial.print(rtc.year());
  Serial.print('/');
  Serial.print(rtc.month());
  Serial.print('/');
  Serial.print(rtc.day());

  Serial.print(" (");
  Serial.print(daysOfTheWeek[rtc.dayOfWeek()-1]);
  Serial.print(") ");

  Serial.print(rtc.hour());
  Serial.print(':');
  Serial.print(rtc.minute());
  Serial.print(':');
  Serial.println(rtc.second());

  Serial.print("Temperature: ");
  Serial.print(rtc.temp()  / 100);
  Serial.print("\xC2\xB0");   //shows degrees character
  Serial.println("C");

  Serial.println();
  delay(1000);
}

(the temperature part)
link to code
and this together:

// Include the libraries
#include "RTClib.h"
#include <TM1637Display.h>

// Define the connections pins
#define CLK 3
#define DIO 4

// Create rtc and display object
RTC_DS3231 rtc;
TM1637Display display = TM1637Display(CLK, DIO);

void setup() {
	// Begin serial communication
	Serial.begin(9600);

	// Check if RTC is connected correctly
	if (! rtc.begin()) {
		Serial.println("Couldn't find RTC");
		while (1);
	}
	// Check if the RTC lost power and if so, set the time
	if (rtc.lostPower()) {
		Serial.println("RTC lost power, lets set the time!");
		// The following line sets the RTC to the date & time this sketch was compiled:
		rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
		// This line sets the RTC with an explicit date & time, for example to set
		// January 21, 2014 at 3am you would call:
		//rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));
	}

	// Set the display brightness (0-7)
	display.setBrightness(5);
	
	// Clear the display
	display.clear();
}

void loop() {
	// Get current date and time
	DateTime now = rtc.now();

	// Create time format to display
	int displaytime = (now.hour() * 100) + now.minute();

	// Display the current time in 24 hour format with leading zeros and a center colon enabled
	display.showNumberDecEx(displaytime, 0b11100000, true);

	delay(1000);
}

if you could give me seggestions or write code for it, it will really be appreciated.

What does the code do now? What does the code NOT do now? What will having the two libraries in one sketch allow you to accomplish?

Please explain why you believe that because you are using the TM1673 with the DS3231(with temp) you need to implement uRTClib and RTClib together. Maybe you have a valid reason, maybe it's just some misconception.

im creating a sort of lighting, heating system with relays, and the code doesnt work if i put them together, errors pop up "conflicting" anyway here is the code together

// Include the libraries
#include "RTClib.h"
#include <TM1637Display.h>


// Define the connections pins
#define CLK 3
#define DIO 4

// Create rtc and display object
RTC_DS3231 rtc;
TM1637Display display = TM1637Display(CLK, DIO);

void setup() {
pinMode(5, OUTPUT);

	// Begin serial communication
	Serial.begin(9600);

	// Check if RTC is connected correctly
	if (! rtc.begin()) {
		Serial.println("Couldn't find RTC");
		while (1);
	}
	// Check if the RTC lost power and if so, set the time
	if (rtc.lostPower()) {
		Serial.println("RTC lost power, lets set the time!");
		// The following line sets the RTC to the date & time this sketch was compiled:
		rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
		// This line sets the RTC with an explicit date & time, for example to set
		// January 21, 2014 at 3am you would call:
		//rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));
	}

	// Set the display brightness (0-7)
	display.setBrightness(2);
	
	// Clear the display
	display.clear();
}

void loop() {
	// Get current date and time
	DateTime now = rtc.now();

	// Create time format to display
	int displaytime = (now.hour() * 100) + now.minute();

    if (now.hour() <= 23 && now.hour() >= 7) {
    digitalWrite(5, HIGH);

  } else {
    digitalWrite(5, LOW);

  }

	// Display the current time in 24 hour format with leading zeros and a center colon enabled
	display.showNumberDecEx(displaytime, 0b11100000, true);
  Serial.print(now.hour());
  Serial.print(":");
  Serial.println(now.minute());

	delay(1000);
}

and i'm trying to put this in

  rtc.refresh();

  Serial.print("Temperature: ");
  Serial.print(rtc.temp()  / 100);
  Serial.print("\xC2\xB0");   //shows degrees character
  Serial.println("C");

The short answer:
Try rtc.getTemperature() instead of rtc.temp(). If it results in compiler errors, tell us which RTClib you're using.

The longer answer how to approach:
The RTClib consists of a few files. Open the RTClib.h file (that is the one that you include) that is part of the library with a text editor and check the available public methods (functions) and members of the class that you use (RTC_DS3231).

/**************************************************************************/
/*!
    @brief  RTC based on the DS3231 chip connected via I2C and the Wire library

/**************************************************************************/
class RTC_DS3231 : RTC_I2C {
public:
  bool begin(TwoWire *wireInstance = &Wire);
  void adjust(const DateTime &dt);
  bool lostPower(void);
  DateTime now();
  Ds3231SqwPinMode readSqwPinMode();
  void writeSqwPinMode(Ds3231SqwPinMode mode);
  bool setAlarm1(const DateTime &dt, Ds3231Alarm1Mode alarm_mode);
  bool setAlarm2(const DateTime &dt, Ds3231Alarm2Mode alarm_mode);
  DateTime getAlarm1();
  DateTime getAlarm2();
  Ds3231Alarm1Mode getAlarm1Mode();
  Ds3231Alarm2Mode getAlarm2Mode();

  bool isEnabled32K(void);
  float getTemperature(); // in Celsius degree
  /*!

              from 0 (Sunday) to 6 (Saturday).
      @return the converted value
  */
  static uint8_t dowToDS3231(uint8_t d) { return d == 0 ? 7 : d; }
};

Based on the Adafruit RTClib library.

Note:
There is an example in that library that uses the function.

Right... but why do you need the two RTC libraries?

7

i need temperature, one does the temperatue while the other doesnt, i am also using the tm1637

8

ill try

thanks so much
