Detailed Description

Initialization and Configuration functions.

  ==============================================================================
              ##### Initialization and de-initialization functions #####
  ==============================================================================
    [..]  This section provides functions allowing to:
      (+) Initialize and configure the DAC.
      (+) De-initialize the DAC.

Function Documentation

HAL_DAC_DeInit()

HAL_StatusTypeDef HAL_DAC_DeInit

(

DAC_HandleTypeDef *

hdac

)

Deinitialize the DAC peripheral registers to their default reset values.

Parameters

hdac	pointer to a DAC_HandleTypeDef structure that contains the configuration information for the specified DAC.

Return values

HAL

status

Definition at line 332 of file stm32f4xx_hal_dac.c.

HAL_DAC_Init()

HAL_StatusTypeDef HAL_DAC_Init

(

DAC_HandleTypeDef *

hdac

)

Initialize the DAC peripheral according to the specified parameters in the DAC_InitStruct and initialize the associated handle.

Parameters

hdac	pointer to a DAC_HandleTypeDef structure that contains the configuration information for the specified DAC.

Return values

HAL

status

Definition at line 271 of file stm32f4xx_hal_dac.c.

HAL_DAC_MspDeInit()

__weak void HAL_DAC_MspDeInit

(

DAC_HandleTypeDef *

hdac

)

DeInitialize the DAC MSP.

Parameters

hdac	pointer to a DAC_HandleTypeDef structure that contains the configuration information for the specified DAC.

Return values

None

Definition at line 393 of file stm32f4xx_hal_dac.c.

HAL_DAC_MspInit()

__weak void HAL_DAC_MspInit

(

DAC_HandleTypeDef *

hdac

)

Initialize the DAC MSP.

Parameters

hdac	pointer to a DAC_HandleTypeDef structure that contains the configuration information for the specified DAC.

Return values

None

Definition at line 377 of file stm32f4xx_hal_dac.c.

HAL_DAC_RegisterCallback()

HAL_StatusTypeDef HAL_DAC_RegisterCallback	(	DAC_HandleTypeDef *	hdac,
		HAL_DAC_CallbackIDTypeDef	CallbackID,
		pDAC_CallbackTypeDef	pCallback
	)

Register a User DAC Callback To be used instead of the weak (overridden) predefined callback.

Note

The HAL_DAC_RegisterCallback() may be called before HAL_DAC_Init() in HAL_DAC_STATE_RESET to register callbacks for HAL_DAC_MSPINIT_CB_ID and HAL_DAC_MSPDEINIT_CB_ID

Parameters

hdac	DAC handle
CallbackID	ID of the callback to be registered This parameter can be one of the following values: HAL_DAC_ERROR_INVALID_CALLBACK DAC Error Callback ID HAL_DAC_CH1_COMPLETE_CB_ID DAC CH1 Complete Callback ID HAL_DAC_CH1_HALF_COMPLETE_CB_ID DAC CH1 Half Complete Callback ID HAL_DAC_CH1_ERROR_ID DAC CH1 Error Callback ID HAL_DAC_CH1_UNDERRUN_CB_ID DAC CH1 UnderRun Callback ID HAL_DAC_CH2_COMPLETE_CB_ID DAC CH2 Complete Callback ID HAL_DAC_CH2_HALF_COMPLETE_CB_ID DAC CH2 Half Complete Callback ID HAL_DAC_CH2_ERROR_ID DAC CH2 Error Callback ID HAL_DAC_CH2_UNDERRUN_CB_ID DAC CH2 UnderRun Callback ID HAL_DAC_MSPINIT_CB_ID DAC MSP Init Callback ID HAL_DAC_MSPDEINIT_CB_ID DAC MSP DeInit Callback ID
pCallback	pointer to the Callback function

Return values

status

Definition at line 1091 of file stm32f4xx_hal_dac.c.

HAL_DAC_UnRegisterCallback()

HAL_StatusTypeDef HAL_DAC_UnRegisterCallback	(	DAC_HandleTypeDef *	hdac,
		HAL_DAC_CallbackIDTypeDef	CallbackID
	)

Unregister a User DAC Callback DAC Callback is redirected to the weak (overridden) predefined callback.

Note

The HAL_DAC_UnRegisterCallback() may be called before HAL_DAC_Init() in HAL_DAC_STATE_RESET to un-register callbacks for HAL_DAC_MSPINIT_CB_ID and HAL_DAC_MSPDEINIT_CB_ID

Parameters

hdac

DAC handle

CallbackID

ID of the callback to be unregistered This parameter can be one of the following values: HAL_DAC_CH1_COMPLETE_CB_ID DAC CH1 transfer Complete Callback ID HAL_DAC_CH1_HALF_COMPLETE_CB_ID DAC CH1 Half Complete Callback ID HAL_DAC_CH1_ERROR_ID DAC CH1 Error Callback ID HAL_DAC_CH1_UNDERRUN_CB_ID DAC CH1 UnderRun Callback ID HAL_DAC_CH2_COMPLETE_CB_ID DAC CH2 Complete Callback ID HAL_DAC_CH2_HALF_COMPLETE_CB_ID DAC CH2 Half Complete Callback ID HAL_DAC_CH2_ERROR_ID DAC CH2 Error Callback ID HAL_DAC_CH2_UNDERRUN_CB_ID DAC CH2 UnderRun Callback ID HAL_DAC_MSPINIT_CB_ID DAC MSP Init Callback ID HAL_DAC_MSPDEINIT_CB_ID DAC MSP DeInit Callback ID HAL_DAC_ALL_CB_ID DAC All callbacks

Return values
