Struct SysTickProfiler 

pub struct SysTickProfiler<const FREQ: u32> { /* private fields */ }

systick implementation of EmbeddedProfiler.

The frequency of the systick is encoded using the parameter FREQ.

Implementations

impl<const FREQ: u32> SysTickProfiler<FREQ>

pub fn new(systick: SYST, sysclk: u32) -> Self

Enable the systick and provide a new EmbeddedProfiler.

Note that the sysclk parameter should come from e.g. the HAL’s clock generation function so the real speed and the declared speed can be compared.

Panics

asserts that the compile time constant FREQ matches the runtime provided sysclk

Trait Implementations

impl<const FREQ: u32> EmbeddedProfiler for SysTickProfiler<FREQ>

fn read_clock(&self) -> EPInstant

Takes a reading from the clock.

fn log_snapshot(&self, snapshot: &EPSnapshot)

Optionally log the snapshot to some output, like a serial port.

fn at_start(&self)

Optional function that gets called at the start of the snapshot recording.

fn at_end(&self)

Optional function that gets called at the end of the snapshot recording.

fn start_snapshot(&self) -> Instant<u64, 1, 1000000>

takes the starting snapshot of a specific trace.

fn end_snapshot( &self, start: Instant<u64, 1, 1000000>, name: &'static str, ) -> Option<EPSnapshot>

computes the duration of the snapshot given the start time, if there hasn’t been overflow.
