ST STM32F2 User Manual

HAL TIM Extension Driver
UM1940
642/1371
DocID028236 Rev 2
Notes
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.
HAL_TIMEx_ConfigCommutationEvent_DMA
Function name
HAL_StatusTypeDef
HAL_TIMEx_ConfigCommutationEvent_DMA
(TIM_HandleTypeDef * htim, uint32_t InputTrigger, uint32_t
CommutationSource)
Function description
Configure the TIM commutation event sequence with DMA.
Parameters
htim: pointer to a TIM_HandleTypeDef structure that
contains the configuration information for TIM module.
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
HAL: status

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

(TIM_HandleTypeDef * htim, TIM_MasterConfigTypeDef *
sMasterConfig)
Function description
Configures the TIM in master mode.
