HAL_StatusTypeDef HAL_TIMEx_ConfigCommutEvent	(	TIM_HandleTypeDef *	htim,
		uint32_t	InputTrigger,
		uint32_t	CommutationSource
	)

Configure the TIM commutation event sequence.

Note

This function is mandatory to use the commutation event in order to update the configuration at each commutation detection on the TRGI input of the Timer, the typical use of this feature is with the use of another Timer(interface Timer) configured in Hall sensor interface, this interface Timer will generate the commutation at its TRGO output (connected to Timer used in this function) each time the TI1 of the Interface Timer detect a commutation at its input TI1.

Parameters

htim	TIM handle
InputTrigger	the Internal trigger corresponding to the Timer Interfacing with the Hall sensor This parameter can be one of the following values: TIM_TS_ITR0: Internal trigger 0 selected TIM_TS_ITR1: Internal trigger 1 selected TIM_TS_ITR2: Internal trigger 2 selected TIM_TS_ITR3: Internal trigger 3 selected TIM_TS_NONE: No trigger is needed
CommutationSource	the Commutation Event source This parameter can be one of the following values: TIM_COMMUTATION_TRGI: Commutation source is the TRGI of the Interface Timer TIM_COMMUTATION_SOFTWARE: Commutation source is set by software using the COMG bit

Return values

Configure the TIM commutation event sequence with DMA.

Note

This function is mandatory to use the commutation event in order to update the configuration at each commutation detection on the TRGI input of the Timer, the typical use of this feature is with the use of another Timer(interface Timer) configured in Hall sensor interface, this interface Timer will generate the commutation at its TRGO output (connected to Timer used in this function) each time the TI1 of the Interface Timer detect a commutation at its input TI1.

The user should configure the DMA in his own software, in This function only the COMDE bit is set
