Function Documentation

ErrorStatus LL_TIM_BDTR_Init	(	TIM_TypeDef *	TIMx,
		LL_TIM_BDTR_InitTypeDef *	TIM_BDTRInitStruct
	)

Configure the Break and Dead Time feature of the timer instance.

Note:

As the bits BK2P, BK2E, BK2F[3:0], BKF[3:0], AOE, BKP, BKE, OSSI, OSSR and DTG[7:0] can be write-locked depending on the LOCK configuration, it can be necessary to configure all of them during the first write access to the TIMx_BDTR register.

Macro IS_TIM_BREAK_INSTANCE(TIMx) can be used to check whether or not a timer instance provides a break input.

Macro IS_TIM_BKIN2_INSTANCE(TIMx) can be used to check whether or not a timer instance provides a second break input.

Parameters:

TIMx	Timer Instance
TIM_BDTRInitStruct	pointer to a LL_TIM_BDTR_InitTypeDef structure (Break and Dead Time configuration data structure)

Return values:

An	ErrorStatus enumeration value: SUCCESS: Break and Dead Time is initialized ERROR: not applicable

ErrorStatus LL_TIM_HALLSENSOR_Init	(	TIM_TypeDef *	TIMx,
		LL_TIM_HALLSENSOR_InitTypeDef *	TIM_HallSensorInitStruct
	)

Configure the Hall sensor interface of the timer instance.

Note:

TIMx CH1, CH2 and CH3 inputs connected through a XOR to the TI1 input channel

TIMx slave mode controller is configured in reset mode. Selected internal trigger is TI1F_ED.

Channel 1 is configured as input, IC1 is mapped on TRC.

Captured value stored in TIMx_CCR1 correspond to the time elapsed between 2 changes on the inputs. It gives information about motor speed.

Channel 2 is configured in output PWM 2 mode.

Compare value stored in TIMx_CCR2 corresponds to the commutation delay.

OC2REF is selected as trigger output on TRGO.

LL_TIM_IC_POLARITY_BOTHEDGE must not be used for TI1 when it is used when TIMx operates in Hall sensor interface mode.

Parameters:

TIMx	Timer Instance
TIM_HallSensorInitStruct	pointer to a LL_TIM_HALLSENSOR_InitTypeDef structure (TIMx HALL sensor interface configuration data structure)
