Alarm 2 gives wrong Alarm bits back

[SimGas]

Hi,

I discovered that Alarm 2 gives wrong alarm bits back when reading them. I'm not sure if the wrong bits are written to the controller or if just the reading is wrong. but I think its a combination of both problems.
Alarm 1 works totally fine

Hi,
I also have a problem with Alarm 2. I would like to run the alarms every day (hour, minute match), but Alarm 2 is triggered every hour (minute match).

Here is my code adding the Alarm:
Clock.setA2Time(0, 14, 02, 100, true, false, false);

Alarm 1 is working fine.
Thanks

Have you tried reading the Alarm2 bits? Do they show the same value as you gave them(100)?

[tichachm]

Yes, the bits returned show 96
I think it should be 4 or 100.

Can you try the following:

Clock.setA2Time(0, 14, 02, 0b1000000, true, false, false);

In my code I use sucessfully the following:

rtc.setA1Time(0, 0, 0, 10,0b00001110, false, false, false); // 1110 means: Alarm, when seconds(10) match
rtc.setA2Time(0, 0, 0, 0b1110000, false, false, false); //111 means: Alarm every minute, at second 00

Hi SimGas,
I changed the value to 0b1000000 it seems to work fine, thanks for your help.
