Am o problema cu modulul RTC DS1307 in sensul ca afiseaza o ora, dupa care nu se mai schimba nimic. Temperatura si umiditatea sunt afisate corect.

Am verificat modulu RTC si functioneaza. Schita folosita

#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());
  
  delay(1000);
}

Se pare ca cele 2 schite nu folosec aceleasi biblioteci pt modulul RTC. Am incercat sa modific schita initiala dupa biblioteca din schita de test, dar au aparut erori de compilare.

Ce ar trebui sa modific?

daniels · Iunie 27, 2023

Schema nu are led conectat la RTC

ionutz2013 · Iunie 27, 2023

Temperatura aia masurata e cea din camera? Pare cam ridicata

validae · Iunie 27, 2023

Dacă nu are casa sau apartamentul izolate, e o temperatură destul de normală când afară sunt 30-32* și soarele bate în geamuri și pereți....

daniels · Iunie 27, 2023

Acum 6 ore, antemir a spus:

Incearca cu un test simplu cu libraria din primul code (RTClib).
RTC va porni mereu cu data/ora la care ai compilat. Dar trebuie sa afiseze incrementarea la secunda.

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

RTC_DS1307 RTC;

void setup() 
{
  Serial.begin(9600);
  
  Wire.begin();
  RTC.begin();
  
  RTC.adjust(DateTime(F(__DATE__), F(__TIME__)));
}

void loop() 
{
  DateTime now = RTC.now();
  Serial.print("Data: ");  
  Serial.print(now.day(), DEC);
  Serial.print('/');
  Serial.print(now.month(), DEC);
  Serial.print('/');
  Serial.print(now.year(), DEC);
  Serial.print("   Ora: ");
  Serial.print(now.hour(), DEC);
  Serial.print(':');
  Serial.print(now.minute(), DEC);
  Serial.print(':');
  Serial.print(now.second(), DEC);
  Serial.println();
  delay(1000); 
}

Am facut testul si merge, se sincronizeaza cu ora si data calculatorului

Interesant proiectul asta. Displayul care il contruiesc eu are lipsa un segment. Cel de sus de la primul digit. Nu ar afisa bine ora 00:00. Doar daca afisaza 0:00 ar merge pe afisajul ala. Si bineinteles temperatura pana la 39° cea ce la mine nu ar exista niciodata. M-ar lua ameteala garantat la temperatura aia in casa.

Asa afiseaza

ionutz2013 · Iunie 27, 2023

E bun atunci. Schema pt display common anode m-ar interesa.

daniels · Iunie 27, 2023

Cred ca merge asa cum e acuma, daca nu comentezi sau de-comentezi segventa asta de cod.

/*
//for common catode
#define DIGIT_ON  HIGH
#define DIGIT_OFF  LOW
#define SEGMENT_ON  LOW
#define SEGMENT_OFF HIGH
*/
// for common anode
#define DIGIT_ON  LOW
#define DIGIT_OFF  HIGH
#define SEGMENT_ON  HIGH
#define SEGMENT_OFF LOW

la mine e cu anod comun si a trebuit sa de-comentez catod comun si sa comentez anod comun

daniels · Iunie 27, 2023

Da, ai dreptate, nu se misca nimic.

Nu cred ca functioneaza cu bibliotecile alea.

daniels · Iunie 27, 2023

Am sa reiau testul,acuma nu mai sunt sigur de nimic.

daniels · Iunie 27, 2023

Am refacut testul, se comporta la fel.

ionutz2013 · Iunie 27, 2023

Incearca cu asta: sunt curios daca merge. Eu nu mai gasesc modulele RTC. am comandat altele si mai am de asteptat pana vin.

daniels · Iunie 27, 2023

Nu pot face schema de mai sus pt ca afisajul e cu interfata seriala si nu am.

Module RTC se gasesc vin in cateva zile

ionutz2013 · Iunie 27, 2023

Mda... 40 lei total. Costa mai mult transportu decat acel modul. Pe aliexpress le-am cumparat cu 10 lei cu tot cu transport inclusiv acea interfata serial pt schema fe mai sus. Acum ramane de vazut daca o sa si functioneze. Sa inteleg ca ai facut ceva in genul la ce am experimentat eu in poza? Eu am folosit o schema fara RTC si ramanea in urma rau.
