Re: DS3231 Alarm Int Output When On Battery Backup

Thank you chipfryer27 for your reply, I am sorry if I was not clear. All I need is to enable the SQW output that matches the alarm when the module goes to battery backup, the battery on the module. I have set the module to go low at every minute with Flowcde already when on power. So all I need, lik...

DS3231 Alarm Int Output When On Battery Backup

Hi everyone, does anyone have a code for Flowcode that I can use to enable the alarm Int output while the DS3231 is on battery backup. At this time my code works fine on power. This would help me to wake the MCU circuits with a power up circuit that I would design. I would be able to shut the main v...

Re: DS3231 Alarm Reset component

Hi Martin, the program works perfectly. I believe that the problem I had with the DS3231 component earlier is that the alarm does not reset (no Reset option) and that the Int pin on the chip is low all the time. I was able to confirm that by writing to the chip register output pin to set it to high ...

DS3231 Alarm Reset component

Hi, will there be a Alarm 1 and 2 Reset component available in the near future for the DS3231?

Re: DS3231 Alarm 1 or 2 Interrupt Not Working Correctly

Okay I was able to use an I2C component to write to the DS3231 address location and register to set the alarm flag so the alarm resets. So I can use it in the flowcode I created. It works great.

Re: DS3231 Alarm 1 or 2 Interrupt Not Working Correctly

After doing many tests and programming with the DS3231 with the Arduino IDE it looks like my problem is that the alarm does not clear. I cannot find a reset alarm in the Flowcode V11 componet DS3231 . Can some one help?

Thank you.

Re: DS3231 Alarm 1 or 2 Interrupt Not Working Correctly

Thank you for the responce. The Arduino does not reset. I can programm all the function on the DS3231 chip including the date and time on the LCD display except the alarm 1 or 2 with the SQW/Int componet settings 1, 2 or 3. The 0 setting for the Int works fine at one trigger per second but not the o...

DS3231 Alarm 1 or 2 Interrupt Not Working Correctly

Hi everyone, I have tried everything to get the alarm Interrupt working on the RTC DS3231. I am using an Arduino Uno R3 using I2C communication on C4 and C5. Everything works except the Alarm if I set the Alarm 1 on the seconds. IE: every minute on 20 seconds. I tried minutes as well and no interrup...
