why STM32f103C8 doesn't have Alarm option in CubeMX?

Hello,

In STM32F103C8 it states that it's possible to have Alarm set and use the interrupts , however in CubeMX there's no option for generating the code like the Other MCU which have Calender as well.

Page 491 of  RM0008 States that there are also Alarm Registers. Is CubeMX missing this ?

#alarm #rtc

Hello,

Alarm option will be activate when you set RTC OUT to ''RTC Output on the Tamper pin''.

Best Regards

Thank you Imen for the reply,

What if I don't want to use the tamper pin?

what i'm trying to achive is to set an alarm for a specific time and put the MCU to sleep and wakeup with that alarm interrupt. so I don't need the tamper pin.

Obviously one solution is to just go with this and leave the tamper pin but I want to know if it's possible to be done without it like in the other MCUs
