Struct Delay

pub struct Delay<TIM, const FREQ: u32>(/* private fields */);

Periodic non-blocking timer that implements embedded_hal_02::blocking::delay traits.

Example: Millisecond precision

To instantiate this with the TIM2 timer and millisecond precision:

let mut delay = dp.TIM2.delay_ms(&clocks);
delay.delay_ms(320_u32);

With millisecond precision, you can wait from 2 ms to 49 days.

Example: Microsecond precision

To instantiate this with the TIM5 timer and microsecond precision:

let delay = dp.TIM5.delay_us(&clocks);
delay.delay_us(30_u32);
delay.delay_ms(5_u32);
delay.delay(5.millis());
delay.delay(3.secs());

With microsecond precision, you can wait from 2 µs to 71 min.

Implementations

impl<TIM: Instance, const FREQ: u32> Delay<TIM, FREQ>

pub fn delay(&mut self, time: TimerDurationU32<FREQ>)

Sleep for given time

Trait Implementations

impl<TIM: Instance, const FREQ: u32> Delay<FREQ> for Delay<TIM, FREQ>

type Error = Infallible

An error that might happen during waiting

fn delay(&mut self, duration: TimerDurationU32<FREQ>) -> Result<(), Self::Error>

Wait until timer duration has expired.

impl<TIM: Instance, const FREQ: u32> DelayNs for Delay<TIM, FREQ>

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.

impl<T, const FREQ: u32> Deref for Delay<T, FREQ>

type Target = FTimer<T, FREQ>
