Trait Implementations

impl Watchdog for Watchdog

fn feed(&mut self)

Feeds an existing watchdog to ensure the processor isn’t reset. Sometimes commonly referred to as “kicking” or “refreshing”.

impl WatchdogDisable for Watchdog

Disables a running watchdog timer so the processor won’t be reset.

fn disable(&mut self)

Disables the watchdog

impl WatchdogEnable for Watchdog

fn start<T>(&mut self, period: T)

where T: Into<Self::Time>,

Enables a watchdog timer to reset the processor if software is frozen or stalled. Pass WatchdogTimeout as the period.

As WDT is driven by a 1024Hz clock, the time until timeout can be calculated as (1 second/1024)*period

EG: Timeout of 2048 cycles = (1/1024)*2048 = 2 seconds

type Time = u8

Unit of time used by the watchdog
