Module stm32l0xx_hal::rtc
source · [−]Expand description
Interface to the Real-time clock (RTC) peripheral.
The real-time clock (RTC) is an independent BCD timer/counter. The RTC provides a time- of-day clock/calendar with programmable alarm interrupts.
Date Types
The date/time types (NaiveDate, NaiveTime and NaiveDateTime), are
re-exported from rtcc, which in turn re-exports
them from chrono.
To use methods like .year() or .hour(), you may need to import the
Datelike or Timelike traits.
Valid Date Range
The RTC only supports two-digit years (00-99). The value 00 corresponds to the year 2000 (not 1970!). Additionally, the year 00 cannot be used because this value is the RTC domain reset default value. This means that dates in the range 2001-01-01 to 2099-12-31 can be represented.
More Information
See STM32L0x2 reference manual, chapter 26 or STM32L0x1 reference manual, chapter 22 for more details.
