Struct OneShotTimer 

pub struct OneShotTimer<'a> { /* private fields */ }

One-shot timer wrapper.

Counts down from a loaded value and stops when it reaches zero.

Implementations

impl OneShotTimer<'_>

pub fn start(&mut self, count: u32)

Start the one-shot timer with a count value.

count is in timer clock ticks (TCXO = 24MHz → 1 tick ≈ 41.7ns).

pub fn start_micros(&mut self, us: u32)

Start the timer for the given duration in microseconds.

Max duration: ~178 seconds at 24MHz (u32 ticks limit). For longer durations, use start_millis() or loop start_micros().

pub fn start_millis(&mut self, ms: u32)

Start the timer for the given duration in milliseconds.

Max duration: ~178,956ms (~178s) at 24MHz. For longer durations, repeat this call in a loop.

pub fn expired(&self) -> bool

Check if the timer has expired.

pub fn wait(&self)

Wait for the timer to expire (busy-loop).

pub fn current(&self) -> u32

Get the current counter value.

pub fn stop(&self)

Stop the timer.

pub fn clear(&self)

Clear the interrupt flag.

Trait Implementations

impl DelayNs for OneShotTimer<'_>

fn delay_ns(&mut self, ns: u32)

Pauses execution for at minimum ns nanoseconds. Pause can be longer if the implementation requires it due to precision/timing issues.

fn delay_us(&mut self, us: u32)

Pauses execution for at minimum us microseconds. Pause can be longer if the implementation requires it due to precision/timing issues.

fn delay_ms(&mut self, ms: u32)

Pauses execution for at minimum ms milliseconds. Pause can be longer if the implementation requires it due to precision/timing issues.
