Problem with RTC module on Arduino Nano Every

Projects General Guidance
1

Does anyone know a lib that works for rtc v2.0 CR1220 gravity DS3231 for arduino nano every? I managed to make it work on arduino nano but it has different atmega structure so it doesn't work on nano every. I tried some libs but no luck...

See if this link helps.

Please post the code which worked with the Nano but not the Nano Every.

Can you attach a hand drawn simple schematic of how you wired things,

I frequently use a ds3231 with Nano Every without issues.

#include "RTClib.h"

RTC_DS1307 rtc;

void setup () {
  Serial.begin(9600);

#ifndef ESP8266
  while (!Serial); // wait for serial port to connect. Needed for native USB
#endif

  if (! rtc.begin()) {
    Serial.println("Couldn't find RTC");
    Serial.flush();
    while (1) delay(10);
  }

  if (! rtc.isrunning()) {
    Serial.println("RTC is NOT running, let's set the time!");
    // When time needs to be set on a new device, or after a power loss, 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));
  }

  // When time needs to be re-set on a previously configured device, 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));
}

void loop() {
 DateTime time = rtc.now();

 //Full Timestamp
 Serial.println(String("DateTime::TIMESTAMP_FULL:\t")+time.timestamp(DateTime::TIMESTAMP_FULL));

 Serial.println("\n");

 //Delay 5s
 delay(5000);
}

I found the solution. This code and lib work for both arduino nano and arduino nano every.
