Struct imxrt_hal::pit::Pit

pub struct Pit<const CHAN: u8> { /* private fields */ }

A periodic interrupt timer (PIT) channel.

Implementations

impl<const CHAN: u8> Pit<CHAN>

pub unsafe fn new<const N: u8>(instance: &Instance<N>) -> Self

where Const<CHAN>: Valid,

Fabricate a PIT channel instance.

Safety

This allows you to produce multiple PIT channels that mutably reference the same memory. You must ensure that writes to the peripheral memory are synchronized across instances.

Use the free function new() to safely acquire the four PIT channels.

pub fn set_interrupt_enable(&mut self, enable: bool)

Enable (true) or disable (false) interrupt generation.

pub fn is_interrupt_enabled(&self) -> bool

Indicates if timeouts will (true) or will not (false) generate interrupts.

pub fn current_timer_value(&self) -> u32

Reads the current time value, in clock ticks.

Returns 0 if the timer is disabled.

pub fn set_load_timer_value(&self, ticks: u32)

Loads the timer value for the next timer run.

ticks is in clock ticks.

pub fn load_timer_value(&self) -> u32

Returns the load timer value for the next timer run, in clock ticks.

pub fn enable(&mut self)

Enable the timer.

pub fn disable(&mut self)

Disable the timer.

pub fn is_enabled(&self) -> bool

Returns true if the PIT channel is enabled.

pub fn is_elapsed(&self) -> bool

Returns true if the timer has elapsed.

pub fn clear_elapsed(&self)

Clear the elapsed flag.

pub fn set_chained(&mut self, chained: bool)

Specify that this channel is chained to the previous channel.

This affects how the timer counts. If you’re looking to chain timers easily, see Chained.

pub fn is_chained(&self) -> bool

Returns true if this channel is chained to the previous channel.
