Struct stm32f1xx_hal::rtc::Rtc

pub struct Rtc { /* fields omitted */ }

Interface to the real time clock

Methods

impl Rtc

pub fn rtc(regs: RTC, bkp: &mut BackupDomain) -> Self

Initialises the RTC. The BackupDomain struct is created by Rcc.bkp.constrain().

pub fn set_seconds(&mut self, seconds: u32)

Set the current rtc value to the specified amount of seconds

pub fn set_alarm(&mut self, seconds: u32)

Sets the time at which an alarm will be triggered

This also clears the alarm flag if it is set

pub fn listen_alarm(&mut self)

Enables the RTCALARM interrupt

pub fn unlisten_alarm(&mut self)

Disables the RTCALARM interrupt

pub fn seconds(&self) -> u32

Reads the current time

pub fn listen_seconds(&mut self)

Enables the RTC second interrupt

pub fn unlisten_seconds(&mut self)

Disables the RTC second interrupt

pub fn clear_second_flag(&mut self)

Clears the RTC second interrupt flag

pub fn clear_alarm_flag(&mut self)

Clears the RTC alarm interrupt flag

pub fn wait_alarm(&mut self) -> Result<(), Void>

Return Ok(()) if the alarm flag is set, Err(nb::WouldBlock) otherwise.

use nb::block;

rtc.set_alarm(rtc.read_counts() + 5);
// NOTE: Safe unwrap because Void can't be returned
block!(rtc.wait_alarm()).unwrap();
