Detailed Description

Function Documentation

LL_TIM_DisableExternalClock()

__STATIC_INLINE void LL_TIM_DisableExternalClock

(

TIM_TypeDef *

TIMx

)

Disable external clock mode 2.

Note

Macro IS_TIM_CLOCKSOURCE_ETRMODE2_INSTANCE(TIMx) can be used to check whether or not a timer instance supports external clock mode2. @rmtoll SMCR ECE LL_TIM_DisableExternalClock

Parameters

TIMx	Timer instance

Return values

None

Definition at line 2657 of file stm32f4xx_ll_tim.h.

LL_TIM_EnableExternalClock()

__STATIC_INLINE void LL_TIM_EnableExternalClock

(

TIM_TypeDef *

TIMx

)

Enable external clock mode 2.

Note

When external clock mode 2 is enabled the counter is clocked by any active edge on the ETRF signal.

Macro IS_TIM_CLOCKSOURCE_ETRMODE2_INSTANCE(TIMx) can be used to check whether or not a timer instance supports external clock mode2. @rmtoll SMCR ECE LL_TIM_EnableExternalClock

Parameters

TIMx	Timer instance

Return values

None

Definition at line 2644 of file stm32f4xx_ll_tim.h.

LL_TIM_IsEnabledExternalClock()

__STATIC_INLINE uint32_t LL_TIM_IsEnabledExternalClock

(

const TIM_TypeDef *

TIMx

)

Indicate whether external clock mode 2 is enabled.

Note

Macro IS_TIM_CLOCKSOURCE_ETRMODE2_INSTANCE(TIMx) can be used to check whether or not a timer instance supports external clock mode2. @rmtoll SMCR ECE LL_TIM_IsEnabledExternalClock

Parameters

TIMx	Timer instance

Return values

State

of bit (1 or 0).

LL_TIM_SetClockSource()

__STATIC_INLINE void LL_TIM_SetClockSource	(	TIM_TypeDef *	TIMx,
		uint32_t	ClockSource
	)

Set the clock source of the counter clock.

Note

when selected clock source is external clock mode 1, the timer input the external clock is applied is selected by calling the LL_TIM_SetTriggerInput() function. This timer input must be configured by calling the LL_TIM_IC_Config() function.

Macro IS_TIM_CLOCKSOURCE_ETRMODE1_INSTANCE(TIMx) can be used to check whether or not a timer instance supports external clock mode1.

Macro IS_TIM_CLOCKSOURCE_ETRMODE2_INSTANCE(TIMx) can be used to check whether or not a timer instance supports external clock mode2. @rmtoll SMCR SMS LL_TIM_SetClockSource
SMCR ECE LL_TIM_SetClockSource

Parameters

TIMx	Timer instance
ClockSource	This parameter can be one of the following values: LL_TIM_CLOCKSOURCE_INTERNAL LL_TIM_CLOCKSOURCE_EXT_MODE1 LL_TIM_CLOCKSOURCE_EXT_MODE2

Return values

None

Definition at line 2694 of file stm32f4xx_ll_tim.h.

LL_TIM_SetEncoderMode()

__STATIC_INLINE void LL_TIM_SetEncoderMode	(	TIM_TypeDef *	TIMx,
		uint32_t	EncoderMode
	)

Set the encoder interface mode.

Note

Macro IS_TIM_ENCODER_INTERFACE_INSTANCE(TIMx) can be used to check whether or not a timer instance supports the encoder mode. @rmtoll SMCR SMS LL_TIM_SetEncoderMode

Parameters

TIMx	Timer instance
EncoderMode	This parameter can be one of the following values: LL_TIM_ENCODERMODE_X2_TI1 LL_TIM_ENCODERMODE_X2_TI2 LL_TIM_ENCODERMODE_X4_TI12

Return values

None
