Struct SysCounter 

pub struct SysCounter<const FREQ: u32>(/* private fields */);

SysTick timer with precision of 1 μs (1 MHz sampling)

Implementations

impl<const FREQ: u32> SysCounter<FREQ>

pub fn listen(&mut self, event: SysEvent)

Starts listening for an event

pub fn unlisten(&mut self, event: SysEvent)

Stops listening for an event

pub fn now(&self) -> TimerInstantU32<FREQ>

pub fn start(&mut self, timeout: TimerDurationU32<FREQ>) -> Result<(), Error>

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

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

Methods from Deref<Target = SystemTimer>

pub fn listen(&mut self, event: SysEvent)

Starts listening for an event

pub fn unlisten(&mut self, event: SysEvent)

Stops listening for an event

pub fn reset(&mut self)

Resets the counter

Trait Implementations

impl<const FREQ: u32> Deref for SysCounter<FREQ>

type Target = SystemTimer

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<const FREQ: u32> DerefMut for SysCounter<FREQ>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<const FREQ: u32> Timer<FREQ> for SysCounter<FREQ>

type Error = Error

An error that might happen during waiting

fn now(&mut self) -> TimerInstantU32<FREQ>

Return current time Instant

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

Start timer with a duration

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

Wait until timer duration has expired. Must return nb::Error::WouldBlock if timer duration is not yet over. Must return OK(()) as soon as timer duration has expired.

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

Tries to stop this timer. An error will be returned if the timer has already been canceled or was never started. An error is also returned if the timer is not Periodic and has already expired.
