RTC DS1307: SimulIDE 1.0.0 SR0-Stable - Linux64

the same sim1-file works very well under…
1.0.0 R1314! (2023-03-08)  
and
1.0.0 RC3 (2022-10)
(tested with uno & nano)

in setup:

Code:

  if (! rtc.isrunning()) {
    Serial.println("RTC is NOT running!");
    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
    Serial.println("RTC adjusted!");
  }
  else {
    Serial.println("RTC is running");
  }


results…
R1314 & RC3: "RTC is running"

SR0-Stable: "RTC is NOT running!"


RTClib is: github.com/adafruit/RTClib


hope that helps…

Code:

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


//  RTC_Millis rtc;
RTC_DS1307 rtc; // i2c 0x68


void setup() {
 while (!Serial);

  Serial.begin(57600);
  Serial.println();
  Serial.println("timestamp: "__DATE__" "__TIME__);

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

  if (! rtc.isrunning()) {
    Serial.println("RTC is NOT running!");
    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
    Serial.println("RTC adjusted!");
  }
  else {
    Serial.println("RTC is running");
  }
}

void loop() {

}

Yes this changed recently to solve an error.
Indeed DS1307 is disabled the first time it's powered on.

Right now it works this way:
When you open the circuit it works as it is powered for the first time.
Then it will "remember" it's state until you close the circuit.

This probably needs an option to save state to the circuit file, but it is not implemented yet.

UUPS…?!?

there is another problem…
DS1307 is not in the component-list anymore – see screenshot parts of R1314 (left) an SR0 (right)

Ouch... you are right

Solved at Rev 1321.

THANK YOU!

I create a new project under R1322 (Linux64):
arduino-uno and rtc-ds1307

but sorry… the same result as yesterday under sr0.
is it me…?

this new sim1-file works perfect under  R1314!

…hope that helps…

Those are the correct results: the first time DS1307 is powered On it is disabled and you have to enable it.

That's the reason for this code:
If DS1307 is not running, then enable it by setting the time/date.

Code:

  if (! rtc.isrunning()) {
    Serial.println("RTC is NOT running!");
    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
    Serial.println("RTC adjusted!");
  }

It was wrong in R1314:
DS1307 was initialized as enabled, indeed it was always enabled and you could not disable it.

sorry… probable my error…?!?

I try the file in the examples-folder:
"Ds1307.sim1"
I can't get it to run correctly – program starts, but seconds do not change. :-/

may be, I need more sleep. ;-)

may be, I need more sleep. ;-)

Who knows, maybe is me who needs more sleep and I didn't understand you in the first place.
I will have a look.

is the example "Ds1307.sim1" running correctly on your machine?

please forgive me…

I would like to help…!

I LOVE SimulIDE!

is the example "Ds1307.sim1" running correctly on your machine?

I never tried, I just tried the code you posted.
In that case, the message "RTC is NOT running!" is correct.
After that the Ds1307 should be enabled when the time is adjusted and it shows the message: "RTC adjusted!"
Then it should run normally.

But you are right that the example in Simulide does not work, seems that there is some error and the clock is never enabled.

It was a silly typo, solved at Rev 1324.

But note that the message "RTC is NOT running!" is correct.
In R1314, the clock would work even if you don't set the time/date the first time, and that was wrong.

Thank you!

In my opinion the default (check) is correct.
the rtc WITH BATTERY gives the actual date & time.

if the user wants a „clean“ rtc, he unchecked the preference.

I think, I have localized a little problem…

please load the example "Ds1307.sim1"…
If the clock-option is checked ("Set current time at start"), the sketch shows the actual time – BUT the seconds did not changed. The "start-time" comes again and again…?!?

tested on SR0 and R1334 using linux64

…hope that helps…

Some day we will get this to work  properly...  
Solved at Rev 1338.

Thank you!

oh oh :-/
I am afraid, there is another problem…

Please try the example "Ds1307.sim1" and uncheck "Set current time at start" in the settings – then start.
The display shows day and month as zero and year as 2048.

…or is it me…?

…hope that helps…

There is something very weird here...

Now I'm getting year 231(with current time), and this happens for all versions, even the older 1.0.0-RC3:



And I can't reproduce your issue, I get 00/00/00 for date, which is not really correct, it should be: 01/01/00.

Sorry… :-/ I tested so much AND get not enough sleep (and could not find the right file for now).

So now I make a NEW reproducible(!) example for you:
it based on the unmodified adafruit-example. I tested this under (the for me available) R1334 and I generate it for UNO, NANO and MEGA and the DS1307 with UNCHECKED option "Set current time at start".

…hope that helps…

Excuse me!

Thanks, now I get the same results.
And I get the correct 2023 when "current time" is checked.

There is something wrong that I can't find yet, I'm investigating it.
