Struct msp430fr2x5x_hal::watchdog::Wdt

pub struct Wdt<MODE> { /* fields omitted */ }

Watchdog timer which can be configured to watchdog or interval (timer) mode

Implementations

impl Wdt<WatchdogMode>

pub fn constrain(wdt: WDT_A) -> Self

Convert WDT peripheral into a watchdog timer (watchdog mode) and disable the watchdog. Set clock source to VLOCLK.

impl<MODE: WatchdogSelect> Wdt<MODE>

pub fn set_aclk(&mut self, _clks: &Aclk) -> &mut Self

Set watchdog clock source to ACLK and halt timer.

pub fn set_vloclk(&mut self) -> &mut Self

Set watchdog clock source to VLOCLK and halt timer.

pub fn set_smclk(&mut self, _clks: &Smclk) -> &mut Self

Set watchdog clock source to SMCLK and halt timer.

impl Wdt<WatchdogMode>

pub fn to_interval(self) -> Wdt<IntervalMode>

Convert to interval mode and pause timer

impl Wdt<IntervalMode>

pub fn to_watchdog(self) -> Wdt<WatchdogMode>

Convert to watchdog mode and pause timer

pub fn enable_interrupts(&mut self) -> &mut Self

Enable interrupts for watchdog, which fires when the watchdog interrupt flag is set in interval mode. This setting does nothing in watchdog mode, but will carry over when switching to interval mode.

pub fn disable_interrupts(&mut self) -> &mut Self

Disable interrupts for watchdog.

Trait Implementations

impl Cancel for Wdt<IntervalMode>

type Error = Void

Error returned when a countdown can't be canceled.

pub fn cancel(&mut self) -> Result<(), Self::Error>

This implementation will never return error even if watchdog has already been paused, hence the Void error type.

impl CountDown for Wdt<IntervalMode>

type Time = WdtClkPeriods

The unit of time used by this timer

pub fn start<T>(&mut self, count: T) where
    T: Into<Self::Time>, 

Starts a new count down

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

If called while timer is not running, this will always return WouldBlock.

impl Periodic for Wdt<IntervalMode>

impl Watchdog for Wdt<WatchdogMode>

pub fn feed(&mut self)

Triggers the watchdog. This must be done once the watchdog is started to prevent the processor being reset.

impl WatchdogDisable for Wdt<WatchdogMode>

pub fn disable(&mut self)

Disables the watchdog

impl WatchdogEnable for Wdt<WatchdogMode>

type Time = WdtClkPeriods

Unit of time used by the watchdog

pub fn start<T>(&mut self, period: T) where
    T: Into<Self::Time>, 

Starts the watchdog with a given period, typically once this is done the watchdog needs to be kicked periodically or the processor is reset.
