Struct Timer

pub struct Timer<'d, T: CoreInstance> { /* private fields */ }

Low-level timer driver.

Implementations

impl<'d, T: CoreInstance> Timer<'d, T>

pub fn new(tim: impl Peripheral<P = T> + 'd) -> Self

Create a new timer driver.

pub fn regs_core(&self) -> TimCore

Get access to the virutal core 16bit timer registers.

Note: This works even if the timer is more capable, because registers for the less capable timers are a subset. This allows writing a driver for a given set of capabilities, and having it transparently work with more capable timers.

pub fn start(&self)

Start the timer.

pub fn stop(&self)

Stop the timer.

pub fn reset(&self)

Reset the counter value to 0

pub fn set_frequency(&self, frequency: Hertz)

Set the frequency of how many times per second the timer counts up to the max value or down to 0.

This means that in the default edge-aligned mode, the timer counter will wrap around at the same frequency as is being set. In center-aligned mode (which not all timers support), the wrap-around frequency is effectively halved because it needs to count up and down.

pub fn set_tick_freq(&mut self, freq: Hertz)

Set tick frequency.

pub fn clear_update_interrupt(&self) -> bool

Clear update interrupt.

Returns whether the update interrupt flag was set.

pub fn enable_update_interrupt(&self, enable: bool)

Enable/disable the update interrupt.

pub fn set_autoreload_preload(&self, enable: bool)

Enable/disable autoreload preload.

pub fn get_frequency(&self) -> Hertz

Get the timer frequency.

pub fn get_clock_frequency(&self) -> Hertz

Get the clock frequency of the timer (before prescaler is applied).

impl<'d, T: BasicNoCr2Instance> Timer<'d, T>

pub fn regs_basic_no_cr2(&self) -> TimBasicNoCr2

Get access to the Baisc 16bit timer registers.

Note: This works even if the timer is more capable, because registers for the less capable timers are a subset. This allows writing a driver for a given set of capabilities, and having it transparently work with more capable timers.

Enable/disable the update dma.

pub fn get_update_dma_state(&self) -> bool

Get the update dma enable/disable state.

impl<'d, T: BasicInstance> Timer<'d, T>

pub fn regs_basic(&self) -> TimBasic

Get access to the Baisc 16bit timer registers.

Note: This works even if the timer is more capable, because registers for the less capable timers are a subset. This allows writing a driver for a given set of capabilities, and having it transparently work with more capable timers.

Note: This works even if the timer is more capable, because registers for the less capable timers are a subset. This allows writing a driver for a given set of capabilities, and having it transparently work with more capable timers.

pub fn set_clock_division(&self, ckd: Ckd)

impl<'d, T: GeneralInstance4Channel> Timer<'d, T>

pub fn regs_gp16(&self) -> TimGp16

Get access to the general purpose 16bit timer registers.

Note: This works even if the timer is more capable, because registers for the less capable timers are a subset. This allows writing a driver for a given set of capabilities, and having it transparently work with more capable timers.
