Struct Rtc 

pub struct Rtc {
    pub regs: RTC,
    /* private fields */
}

Real Time Clock peripheral

Fields

regs: RTC

RTC Peripheral register definition

Implementations

impl Rtc

pub fn new( regs: RTC, clock_source: ClockSource, bypass: bool, apb1: &mut APB1, bdcr: &mut BDCR, pwr: &mut PWR, ) -> Self

Create and enable a new RTC, and configure its clock source and prescalers. From AN4759, Table 7, when using the LSE (The only clock source this module supports currently), set prediv_s to 255, and prediv_a to 127 to get a calendar clock of 1Hz. The bypass argument is true if you’re using an external oscillator that doesn’t connect to OSC32_IN, such as a MEMS resonator. Note: You may need to run dp.RCC.apb1enr.modify(|_, w| w.pwren().set_bit()); before constraining RCC, eg before running this constructor. Note that if using HSE as the clock source, we assume you’ve already enabled it, eg in clock config.

pub fn set_24h_fmt(&mut self)

Sets calendar clock to 24 hr format

pub fn set_12h_fmt(&mut self)

Sets calendar clock to 12 hr format

pub fn is_24h_fmt(&self) -> bool

Reads current hour format selection

pub fn set_alarm(&mut self, exti: &mut EXTI)

Setup the alarm. See AN4759, section 2.3.1. sleep_time is in ms. Table 8 desribes these steps.

pub fn set_wakeup(&mut self, exti: &mut EXTI, sleep_time: f32)

Setup periodic auto-wakeup interrupts. See ST AN4759, Table 11, and more broadly, section 2.4.1. See also reference manual, section 27.5. In addition to running this function, set up the interrupt handling function by adding the line make_rtc_interrupt_handler!(RTC_WKUP); somewhere in the body of your program. sleep_time is in ms.

pub fn set_wakeup_interval(&mut self, sleep_time: f32)

Change the sleep time for the auto wakeup, after it’s been set up. Sleep time is in MS. Major DRY from set_wakeup.

pub fn clear_wakeup_flag(&mut self)

Clears the wakeup flag. Must be cleared manually after every RTC wakeup. Alternatively, you could handle this in the EXTI handler function.

Trait Implementations

impl Rtcc for Rtc

fn set_time(&mut self, time: &NaiveTime) -> Result<(), Self::Error>
