Struct Wdt

pub struct Wdt<TG> { /* private fields */ }

Watchdog timer

Implementations

impl<TG> Wdt<TG>

where TG: TimerGroupInstance,

Watchdog driver

pub fn new() -> Self

Construct a new instance of Wdt

pub fn enable(&mut self)

Enable the watchdog timer instance

pub fn disable(&mut self)

Disable the watchdog timer instance

pub unsafe fn set_wdt_enabled(&mut self, enabled: bool)

Forcibly enable or disable the watchdog timer

Safety

This bypasses the usual ownership rules for the peripheral, so users must take care to ensure that no driver instance is active for the timer.

pub fn feed(&mut self)

Feed the watchdog timer

pub fn set_timeout(&mut self, stage: MwdtStage, timeout: MicrosDurationU64)

Set the timeout, in microseconds, of the watchdog timer

pub fn set_stage_action(&mut self, stage: MwdtStage, action: MwdtStageAction)

Set the stage action of the MWDT for a specific stage.

This function modifies MWDT behavior only if a custom bootloader with the following modifications is used:

• ESP_TASK_WDT_EN parameter disabled
• ESP_INT_WDT parameter disabled

Trait Implementations

impl<TG> Default for Wdt<TG>

where TG: TimerGroupInstance,

fn default() -> Self

Returns the “default value” for a type.

impl<TG> InterruptConfigurable for Wdt<TG>

where TG: TimerGroupInstance,

fn set_interrupt_handler(&mut self, handler: InterruptHandler)

Set the interrupt handler

impl<TG> Watchdog for Wdt<TG>

where TG: TimerGroupInstance,

fn feed(&mut self)

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

impl<TG> WatchdogDisable for Wdt<TG>

where TG: TimerGroupInstance,

fn disable(&mut self)

Disables the watchdog

impl<TG> WatchdogEnable for Wdt<TG>

where TG: TimerGroupInstance,

type Time = Duration<u64, 1, 1000000>

Unit of time used by the watchdog

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.
