Implementations

source

impl Rtc<Lse>

source

pub fn new(regs: RTC, pwr: &mut PWR) -> Self

Create and enable a new RTC with external crystal or ceramic resonator and default prescalers.

source

pub fn with_config(
    regs: RTC,
    pwr: &mut PWR,
    mode: LSEClockMode,
    prediv_s: u16,
    prediv_a: u8
) -> Self

Create and enable a new RTC, and configure its clock source and prescalers.

From AN3371, Table 3, when using the LSE, set prediv_s to 255, and prediv_a to 127 to get a calendar clock of 1Hz.

source

impl Rtc<Lsi>

source

pub fn new_lsi(regs: RTC, pwr: &mut PWR) -> Self

Create and enable a new RTC with internal crystal and default prescalers.

source

pub fn lsi_with_config(
    regs: RTC,
    pwr: &mut PWR,
    prediv_s: u16,
    prediv_a: u8
) -> Self

Create and enable a new RTC, and configure its clock source and prescalers.

From AN3371, Table 3, when using the LSI, set prediv_s to 249, and prediv_a to 127 to get a calendar clock of 1Hz.

source

impl<CS> Rtc<CS>

source

pub fn set_prescalers(&mut self, prediv_s: u16, prediv_a: u8)

source

pub fn set_time(&mut self, time: &Time) -> Result<(), Error>

Set the time using time::Time.

source

pub fn set_seconds(&mut self, seconds: u8) -> Result<(), Error>

Set the seconds [0-59].

source

pub fn set_minutes(&mut self, minutes: u8) -> Result<(), Error>

Set the minutes [0-59].

source

pub fn set_hours(&mut self, hours: u8) -> Result<(), Error>

Set the hours [0-23].

source

pub fn set_weekday(&mut self, weekday: u8) -> Result<(), Error>

Set the day of week [1-7].

source

pub fn set_day(&mut self, day: u8) -> Result<(), Error>

Set the day of month [1-31].

source

pub fn set_month(&mut self, month: u8) -> Result<(), Error>

Set the month [1-12].

source

pub fn set_year(&mut self, year: u16) -> Result<(), Error>

Set the year [1970-2069].

The year cannot be less than 1970, since the Unix epoch is assumed (1970-01-01 00:00:00). Also, the year cannot be greater than 2069 since the RTC range is 0 - 99.

source

pub fn set_date(&mut self, date: &Date) -> Result<(), Error>

Set the date.

The year cannot be less than 1970, since the Unix epoch is assumed (1970-01-01 00:00:00). Also, the year cannot be greater than 2069 since the RTC range is 0 - 99.

source

pub fn set_datetime(&mut self, date: &PrimitiveDateTime) -> Result<(), Error>

Set the date and time.

The year cannot be less than 1970, since the Unix epoch is assumed (1970-01-01 00:00:00). Also, the year cannot be greater than 2069 since the RTC range is 0 - 99.
