Flowcode Support Board

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 interrupt. If I set the Alarm for every second, it works just fine. I am attaching an example of my program. If someone could help that would be great.

Note: I use a scope to monitor the Interrupt pin.

Than you,
Pierre

Could it be the watchdog timer is resetting the chip?

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 other settings.

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.

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.
