Function Documentation

HAL_StatusTypeDef HAL_DFSDM_Channel_RegisterCallback	(	DFSDM_Channel_HandleTypeDef *	hdfsdm_channel,
		HAL_DFSDM_Channel_CallbackIDTypeDef	CallbackID,
		pDFSDM_Channel_CallbackTypeDef	pCallback
	)

Register a user DFSDM channel callback to be used instead of the weak predefined callback.

Parameters:

hdfsdm_channel	DFSDM channel handle.
CallbackID	ID of the callback to be registered. This parameter can be one of the following values: HAL_DFSDM_CHANNEL_CKAB_CB_ID clock absence detection callback ID. HAL_DFSDM_CHANNEL_SCD_CB_ID short circuit detection callback ID. HAL_DFSDM_CHANNEL_MSPINIT_CB_ID MSP init callback ID. HAL_DFSDM_CHANNEL_MSPDEINIT_CB_ID MSP de-init callback ID.
pCallback	pointer to the callback function.

Return values:

HAL status.

HAL_StatusTypeDef HAL_DFSDM_Channel_UnRegisterCallback	(	DFSDM_Channel_HandleTypeDef *	hdfsdm_channel,
		HAL_DFSDM_Channel_CallbackIDTypeDef	CallbackID
	)

Unregister a user DFSDM channel callback.

DFSDM channel callback is redirected to the weak predefined callback.

Parameters:

hdfsdm_channel	DFSDM channel handle.
CallbackID	ID of the callback to be unregistered. This parameter can be one of the following values: HAL_DFSDM_CHANNEL_CKAB_CB_ID clock absence detection callback ID. HAL_DFSDM_CHANNEL_SCD_CB_ID short circuit detection callback ID. HAL_DFSDM_CHANNEL_MSPINIT_CB_ID MSP init callback ID. HAL_DFSDM_CHANNEL_MSPDEINIT_CB_ID MSP de-init callback ID.
