Struct bl702_hal::delay::McycleDelay

pub struct McycleDelay { /* private fields */ }

Use RISCV machine-mode cycle counter (mcycle) as a delay provider.

This can be used for high resolution delays for device initialization, bit-banging protocols, etc

Implementations

impl McycleDelay

pub fn new(freq: u32) -> Self

Constructs the delay provider based on core clock frequency freq

pub fn get_cycle_count() -> u64

Retrieves the cycle count for the current HART

pub fn cycles_since(previous_cycle_count: u64) -> u64

Returns the number of elapsed cycles since previous_cycle_count

pub fn delay_cycles(cycle_count: u64)

Performs a busy-wait loop until the number of cycles cycle_count has elapsed

Trait Implementations

impl Clone for McycleDelay

fn clone(&self) -> McycleDelay
