Time events with the stopwatch or set a countdown timer with the Timer s app on your tracker. Charge 5 automatically goes into snooze mode if you ignore the alarm for more than 1 minute. Snooze the alarm as many times as you want. To snooze the alarm for 9 minutes, swipe down from the top of the screen. To dismiss the alarm, swipe up from the bottom of the screen and tap the dismiss icon. When an alarm goes off, your tracker vibrates. If Smart Wake can’t find the best time to wake you, your alarm alerts you at the set time.įor more information, see the related help article. It avoids waking you during deep sleep so you're more likely to wake up feeling refreshed.

When setting an alarm, turn on Smart Wake to allow your tracker to find the best time to wake you starting 30 minutes before the alarm time you set. Set one-time or recurring alarms with the Alarms app. You can also time events with the stopwatch or set a countdown timer. Set up to 8 alarms to occur once or on multiple days of the week. Really appreciate your help, I'm unsuccessfully trying for days now.Alarms vibrate to wake or alert you at a time you set.

In the end, I just want to trigger the interrupt once every hour, e.g. How long should the LOW signal from the SQW pin usually be? Pin still stays low after the first interrupt, ist there anything else I have to change? clear A1F/A2F flags for previously set alarmsīut I am not 100% sure if this was right because actually nothing really changed.

I changed the code in DS3231.cpp to this : There are multiple get methods which allow you to get the time from your rtc, then add 30s and set alarm 1 again. If you want to trigger an alarm after 30 seconds, you need to set the time again. The example just triggers once at a defined time. Reply to this email directly, view it on GitHub, or mute the thread.Īhh OK, that's a completely new use case. You are receiving this because you commented. If you want to sleep again, you'll need to either powerDown again in wakeUp or the loop.ĭid you change the Times that are configured here? Afterwards the Arduino is awake and will run the loop. In my example, you let the arduino sleep and then wakeUp is called. Therefore it will run after setup (see arduino docs: ) The loop function is the one, that is automatically run when the arduino is awake. loop is started once the device wakes up again powerDown(SLEEP_FOREVER, ADC_OFF, BOD_OFF) checkAlarmEnabled( 2)) ĪttachInterrupt( digitalPinToInterrupt(wakeUpPin), wakeUp, FALLING) setA2Time( 0, 0, 30, ALARM_BITS, false, false, false) tA2Time(Day, Hour, Minute, AlarmBits, DayOfWeek, 12 hour mode, PM)Ĭlock. setA1Time( 0, 0, 0, 0, ALARM_BITS, false, false, false) tA1Time(Day, Hour, Minute, Second, AlarmBits, DayOfWeek, 12 hour mode, PM)Ĭlock. This is the interesting part which sets the AlarmBits and configures, when the Alarm be triggeredīyte ALRM1_SET = ALRM1_MATCH_MIN_SEC // trigger A1 when minute and second matchīyte ALRM2_SET = ALRM2_MATCH_MIN // trigger A2 when minute matches (and second is 0 as A2 does not support seconds) # define ALRM2_MATCH_HR_MIN 0b100 // when hours and minutes match # define ALRM2_MATCH_MIN 0b110 // when minutes match # define ALRM2_ONCE_PER_MIN 0b111 // once per minute (00 seconds of every minute) # define ALRM1_MATCH_HR_MIN_SEC 0b1000 // when hours, minutes, and seconds match # define ALRM1_MATCH_MIN_SEC 0b1100 // when minutes and seconds match # define ALRM1_MATCH_SEC 0b1110 // when seconds match

# define ALRM1_MATCH_EVERY_SEC 0b1111 // once a second They need to be combined into a single value (see below) Those are the ALARM Bits that can be used * Sets an alarm using a DS3231 device, goes to sleep and wakes up again
