◆ LL_LPTIM_ConfigTrigger()

__STATIC_INLINE void LL_LPTIM_ConfigTrigger	(	LPTIM_TypeDef *	LPTIMx,
		uint32_t	Source,
		uint32_t	Filter,
		uint32_t	Polarity
	)

Configure the external trigger used as a trigger event for the LPTIM.

Note: This function must be called when the LPTIM instance is disabled.; An internal clock source must be present when a digital filter is required for the trigger. @rmtoll CFGR TRIGSEL LL_LPTIM_ConfigTrigger
CFGR TRGFLT LL_LPTIM_ConfigTrigger
CFGR TRIGEN LL_LPTIM_ConfigTrigger

Parameters

LPTIMx	Low-Power Timer instance
Source	This parameter can be one of the following values: LL_LPTIM_TRIG_SOURCE_GPIO LL_LPTIM_TRIG_SOURCE_RTCALARMA LL_LPTIM_TRIG_SOURCE_RTCALARMB LL_LPTIM_TRIG_SOURCE_RTCTAMP1 LL_LPTIM_TRIG_SOURCE_TIM1_TRGO LL_LPTIM_TRIG_SOURCE_TIM5_TRGO
Filter	This parameter can be one of the following values: LL_LPTIM_TRIG_FILTER_NONE LL_LPTIM_TRIG_FILTER_2 LL_LPTIM_TRIG_FILTER_4 LL_LPTIM_TRIG_FILTER_8
Polarity	This parameter can be one of the following values: LL_LPTIM_TRIG_POLARITY_RISING LL_LPTIM_TRIG_POLARITY_FALLING LL_LPTIM_TRIG_POLARITY_RISING_FALLING

Return values

None

Definition at line 743 of file stm32f4xx_ll_lptim.h.

◆ LL_LPTIM_DisableTimeout()

__STATIC_INLINE void LL_LPTIM_DisableTimeout ( LPTIM_TypeDef * LPTIMx )

Disable the timeout function.

Note: This function must be called when the LPTIM instance is disabled.; A trigger event arriving when the timer is already started will be ignored. @rmtoll CFGR TIMOUT LL_LPTIM_DisableTimeout

Parameters

LPTIMx Low-Power Timer instance

Return values

None

Definition at line 688 of file stm32f4xx_ll_lptim.h.

◆ LL_LPTIM_EnableTimeout()

__STATIC_INLINE void LL_LPTIM_EnableTimeout ( LPTIM_TypeDef * LPTIMx )

Enable the timeout function.

Note: This function must be called when the LPTIM instance is disabled.; The first trigger event will start the timer, any successive trigger event will reset the counter and the timer will restart.; The timeout value corresponds to the compare value; if no trigger occurs within the expected time frame, the MCU is waked-up by the compare match event. @rmtoll CFGR TIMOUT LL_LPTIM_EnableTimeout

Parameters

LPTIMx Low-Power Timer instance

Return values

None

Definition at line 674 of file stm32f4xx_ll_lptim.h.

◆ LL_LPTIM_GetTriggerFilter()

__STATIC_INLINE uint32_t LL_LPTIM_GetTriggerFilter ( const LPTIM_TypeDef * LPTIMx )

Get actual external trigger filter. @rmtoll CFGR TRGFLT LL_LPTIM_GetTriggerFilter.

Parameters

LPTIMx Low-Power Timer instance

Return values

Returned

value can be one of the following values:

LL_LPTIM_TRIG_FILTER_NONE
LL_LPTIM_TRIG_FILTER_2
LL_LPTIM_TRIG_FILTER_4
LL_LPTIM_TRIG_FILTER_8

Definition at line 775 of file stm32f4xx_ll_lptim.h.

◆ LL_LPTIM_GetTriggerPolarity()

__STATIC_INLINE uint32_t LL_LPTIM_GetTriggerPolarity ( const LPTIM_TypeDef * LPTIMx )

Get actual external trigger polarity. @rmtoll CFGR TRIGEN LL_LPTIM_GetTriggerPolarity.

Parameters

LPTIMx Low-Power Timer instance

Return values

Returned

value can be one of the following values:

LL_LPTIM_TRIG_POLARITY_RISING
LL_LPTIM_TRIG_POLARITY_FALLING
LL_LPTIM_TRIG_POLARITY_RISING_FALLING

Definition at line 789 of file stm32f4xx_ll_lptim.h.

◆ LL_LPTIM_GetTriggerSource()

__STATIC_INLINE uint32_t LL_LPTIM_GetTriggerSource ( const LPTIM_TypeDef * LPTIMx )

Get actual external trigger source. @rmtoll CFGR TRIGSEL LL_LPTIM_GetTriggerSource.

Parameters

LPTIMx Low-Power Timer instance

Return values

Returned

value can be one of the following values:

LL_LPTIM_TRIG_SOURCE_GPIO
LL_LPTIM_TRIG_SOURCE_RTCALARMA
LL_LPTIM_TRIG_SOURCE_RTCALARMB
LL_LPTIM_TRIG_SOURCE_RTCTAMP1
LL_LPTIM_TRIG_SOURCE_TIM1_TRGO
LL_LPTIM_TRIG_SOURCE_TIM5_TRGO

◆ LL_LPTIM_IsEnabledTimeout()

__STATIC_INLINE uint32_t LL_LPTIM_IsEnabledTimeout ( const LPTIM_TypeDef * LPTIMx )

Indicate whether the timeout function is enabled. @rmtoll CFGR TIMOUT LL_LPTIM_IsEnabledTimeout.

Parameters

LPTIMx Low-Power Timer instance

Return values

State of bit (1 or 0).

Definition at line 699 of file stm32f4xx_ll_lptim.h.

◆ LL_LPTIM_TrigSw()

__STATIC_INLINE void LL_LPTIM_TrigSw ( LPTIM_TypeDef * LPTIMx )

Start the LPTIM counter.

Note: This function must be called when the LPTIM instance is disabled. @rmtoll CFGR TRIGEN LL_LPTIM_TrigSw

Parameters

LPTIMx Low-Power Timer instance

Return values

None
