Detailed Description

Function Documentation

LL_LPTIM_DisableEncoderMode()

__STATIC_INLINE void LL_LPTIM_DisableEncoderMode

(

LPTIM_TypeDef *

LPTIMx

)

Disable the encoder mode.

Note

This function must be called when the LPTIM instance is disabled. CFGR ENC LL_LPTIM_DisableEncoderMode

Parameters

LPTIMx

Low-Power Timer instance

Return values

None

Definition at line 1054 of file stm32l4xx_ll_lptim.h.

{
  CLEAR_BIT(LPTIMx->CFGR, LPTIM_CFGR_ENC);
}

LL_LPTIM_EnableEncoderMode()

__STATIC_INLINE void LL_LPTIM_EnableEncoderMode

(

LPTIM_TypeDef *

LPTIMx

)

Enable the encoder mode.

Note

This function must be called when the LPTIM instance is disabled.

In this mode the LPTIM instance must be clocked by an internal clock source. Also, the prescaler division ratio must be equal to 1.

LPTIM instance must be configured in continuous mode prior enabling the encoder mode. CFGR ENC LL_LPTIM_EnableEncoderMode

Parameters

LPTIMx

Low-Power Timer instance

Return values

None

Definition at line 1042 of file stm32l4xx_ll_lptim.h.

{
  SET_BIT(LPTIMx->CFGR, LPTIM_CFGR_ENC);
}

LL_LPTIM_GetEncoderMode()

__STATIC_INLINE uint32_t LL_LPTIM_GetEncoderMode

(

LPTIM_TypeDef *

LPTIMx

)

Get actual encoder mode. CFGR CKPOL LL_LPTIM_GetEncoderMode.

Parameters

LPTIMx

Low-Power Timer instance

Return values

Returned

value can be one of the following values: LL_LPTIM_ENCODER_MODE_RISING LL_LPTIM_ENCODER_MODE_FALLING LL_LPTIM_ENCODER_MODE_RISING_FALLING

Definition at line 1026 of file stm32l4xx_ll_lptim.h.

{
  return (uint32_t)(READ_BIT(LPTIMx->CFGR, LPTIM_CFGR_CKPOL));
}

LL_LPTIM_IsEnabledEncoderMode()

__STATIC_INLINE uint32_t LL_LPTIM_IsEnabledEncoderMode

(

LPTIM_TypeDef *

LPTIMx

)

Indicates whether the LPTIM operates in encoder mode. CFGR ENC LL_LPTIM_IsEnabledEncoderMode.

Parameters

LPTIMx

Low-Power Timer instance

Return values

State

of bit (1 or 0).

Definition at line 1065 of file stm32l4xx_ll_lptim.h.

{
  return (((READ_BIT(LPTIMx->CFGR, LPTIM_CFGR_ENC) == LPTIM_CFGR_ENC)? 1UL : 0UL));
}

LL_LPTIM_SetEncoderMode()

__STATIC_INLINE void LL_LPTIM_SetEncoderMode	(	LPTIM_TypeDef *	LPTIMx,
		uint32_t	EncoderMode
	)

Configure the encoder mode.

Note

This function must be called when the LPTIM instance is disabled. CFGR CKPOL LL_LPTIM_SetEncoderMode

Parameters

LPTIMx	Low-Power Timer instance
EncoderMode	This parameter can be one of the following values: LL_LPTIM_ENCODER_MODE_RISING LL_LPTIM_ENCODER_MODE_FALLING LL_LPTIM_ENCODER_MODE_RISING_FALLING

Return values

None
