Struct Rtc

pub struct Rtc { /* private fields */ }

RTC driver.

Implementations

impl Rtc

pub const BACKUP_REGISTER_COUNT: usize = 20usize

Number of backup registers of this instance.

pub fn new(_rtc: impl Peripheral<P = RTC>, rtc_config: RtcConfig) -> Self

Create a new RTC instance.

pub const fn time_provider(&self) -> RtcTimeProvider

Acquire a RtcTimeProvider instance.

pub fn set_datetime(&mut self, t: DateTime) -> Result<(), RtcError>

Set the datetime to a new value.

Errors

Will return RtcError::InvalidDateTime if the datetime is not a valid range.

pub fn now(&self) -> Result<DateTime, RtcError>

Return the current datetime.

Errors

Will return an RtcError::InvalidDateTime if the stored value in the system is not a valid DayOfWeek.

pub fn get_daylight_savings(&self) -> bool

Check if daylight savings time is active.

pub fn set_daylight_savings(&mut self, daylight_savings: bool)

Enable/disable daylight savings time.

pub fn read_backup_register(&self, register: usize) -> Option<u32>

Read content of the backup register.

The registers retain their values during wakes from standby mode or system resets. They also retain their value when Vdd is switched off as long as V_BAT is powered.

pub fn write_backup_register(&self, register: usize, value: u32)

Set content of the backup register.

The registers retain their values during wakes from standby mode or system resets. They also retain their value when Vdd is switched off as long as V_BAT is powered.
