bonjour

j ai un problème avec mon module ds1307

​j ai teste avec plusieurs librerie ,plusieurs carte (mega 2560 ,nano et duemilanove )

après televerser

code 

#include <Wire.h>
#include "RTClib.h"

   #include "TM1637.h"
   #define ON 1
   #define OFF 0
   int8_t TimeDisp[] = {0x00,0x00,0x00,0x00};
   unsigned char ClockPoint = 1;
   #define CLK 2//pins definitions for TM1637  
   #define DIO 3
   TM1637 tm1637(CLK,DIO);

#if defined(ARDUINO_ARCH_SAMD)
// for Zero, output on USB Serial console, remove line below if using programming port to program the Zero!
#define Serial SerialUSB
#endif

RTC_DS1307 rtc;

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

void setup () {

    tm1637.set();
    tm1637.init(); 
  
#ifndef ESP8266
 while (!Serial); // for Leonardo/Micro/Zero
#endif

  Serial.begin(9600);
  if (! rtc.begin()) {
    Serial.println("Couldn't find RTC");
    while (1);
  }

  if (! rtc.isrunning()) {
    Serial.println("RTC is NOT running!");
  }
    // 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));
  
}

void loop () {
    DateTime now = rtc.now();
    
    //Serial.print(now.year(), DEC);
    //Serial.print('/');
    //Serial.print(now.month(), DEC);
    //Serial.print('/');
    //Serial.print(now.day(), DEC);
    //Serial.print(" (");
    //Serial.print(daysOfTheWeek[now.dayOfTheWeek()]);
    //Serial.print(") ");
    Serial.print(now.hour(), DEC);
    Serial.print(':');
    Serial.print(now.minute(), DEC);
    //Serial.print(':');
    //Serial.print(now.second(), DEC);
    Serial.println();    
   // Serial.print(" since midnight 1/1/1970 = ");
   // Serial.print(now.unixtime());
   // Serial.print("s = ");
   // Serial.print(now.unixtime() / 86400L);
   // Serial.println("d");    
   // Serial.println();
   // delay(5000);
    
      tm1637.point(POINT_ON);
      TimeDisp[0] = now.hour() / 10;
      TimeDisp[1] = now.hour() % 10;
      TimeDisp[2] = now.minute() / 10;
      TimeDisp[3] = now.minute() % 10; 
      tm1637.display(TimeDisp);
      delay(500);
      tm1637.point(POINT_OFF);
      tm1637.display(TimeDisp);
      delay(500);
    
    
}

le moniteur serie me donne sa

RTC ne fonctionne pas !
