Struct stm32wlxx_hal::lptim::LpTim2

pub struct LpTim2 { /* private fields */ }

Low-power timer 2 driver.

Implementations

impl LpTim2

pub fn new_trigger_pin<P: LpTim2Etr>( &mut self, filter: Filter, pol: TrgPol, pin: P, cs: &CriticalSection ) -> LpTim2Trg<P>

Setup a new pin trigger.

Panics

• (debug) timer is enabled.

Example

See LpTim3::new_trigger_pin.

pub fn free_trigger_pin<P: LpTim2Etr>(&mut self, pin: LpTim2Trg<P>) -> P

Free the trigger pin previously created with new_trigger_pin.

This is will the trigger source to a software trigger.

Panics

• (debug) timer is enabled.

Example

See LpTim3::free_trigger_pin.

impl LpTim2

pub fn new_output_pin<P: LpTim2Out>( &mut self, pin: P, cs: &CriticalSection ) -> LpTim2OutPin<P>

Setup a new output pin.

pub fn free_output_pin<P: LpTim2Out>(&mut self, pin: LpTim2OutPin<P>) -> P

Free the output pin previously created with new_output_pin.
