Setting Specific Time Alarm on PCF85063A

Hi,

I'm having trouble setting an alarm on the PCF85063A RTC for a specific time. Here are the steps :

I’m using the following registers:

Then I'm using register 0x01 with the value 0x80 to set the alarm interrupt .

The alarm does not trigger at the specified time. Can suggest the correct procedure to set up an alarm?

Thanks!

Hello Vaishali9,

I hope all is great with you. Thank you for using the NXP communities.

Are you enabling the ALARM interrupt?

control_2 = RTC_CTRL_2_DEFAULT | RTC_ALARM_AIE; // enable interrupt

control_2 &= ~RTC_ALARM_AF;

I do recommend using the following example code as a reference for your design.

Please note that this is not an official driver.

I hope this information helps.

Regards,

David
