Struct RtcBorrow 

pub struct RtcBorrow<'a> { /* private fields */ }

Contains an RTC borrow.

Methods from Deref<Target = Rtc>

pub fn calibrate(&mut self, clock_drift: f32, period: RtcCalibrationCyclePeriod)

Calibrate the clock drift.

clock_drift can be adjusted from -487.1 ppm to 488.5 ppm and is clamped to this range.

Note

To perform a calibration when async_prescaler is less then 3, sync_prescaler has to be reduced accordingly (see RM0351 Rev 9, sec 38.3.12).

pub const BACKUP_REGISTER_COUNT: usize = 32usize

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 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.

Trait Implementations

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> DerefMut for RtcBorrow<'a>

fn deref_mut(&mut self) -> &mut Self::Target
