#define __HAL_DCMI_ENABLE_IT	(		__HANDLE__,
			__INTERRUPT__
	)		((__HANDLE__)->Instance->IER |= (__INTERRUPT__))

Enable the specified DCMI interrupts.

Parameters

<strong>HANDLE</strong>	DCMI handle
<strong>INTERRUPT</strong>	specifies the DCMI interrupt sources to be enabled. This parameter can be any combination of the following values: DCMI_IT_FRAME: Frame capture complete interrupt mask DCMI_IT_OVF: Overflow interrupt mask DCMI_IT_ERR: Synchronization error interrupt mask DCMI_IT_VSYNC: VSYNC interrupt mask DCMI_IT_LINE: Line interrupt mask

#define __HAL_DCMI_GET_FLAG	(		__HANDLE__,
			__FLAG__
	)

Value:

((((__FLAG__) & (DCMI_SR_INDEX|DCMI_MIS_INDEX)) == 0x0)? ((__HANDLE__)->Instance->RIS & (__FLAG__)) :\
 (((__FLAG__) & DCMI_SR_INDEX) == 0x0)? ((__HANDLE__)->Instance->MIS & (__FLAG__)) : ((__HANDLE__)->Instance->SR & (__FLAG__)))

Get the DCMI pending flag.

Parameters

DCMI handle

<strong>FLAG</strong>

Get the specified flag. This parameter can be one of the following values (no combination allowed) DCMI_FLAG_HSYNC: HSYNC pin state (active line / synchronization between lines) DCMI_FLAG_VSYNC: VSYNC pin state (active frame / synchronization between frames) DCMI_FLAG_FNE: FIFO empty flag DCMI_FLAG_FRAMERI: Frame capture complete flag mask DCMI_FLAG_OVRRI: Overrun flag mask DCMI_FLAG_ERRRI: Synchronization error flag mask DCMI_FLAG_VSYNCRI: VSYNC flag mask DCMI_FLAG_LINERI: Line flag mask DCMI_FLAG_FRAMEMI: DCMI Capture complete masked interrupt status DCMI_FLAG_OVRMI: DCMI Overrun masked interrupt status DCMI_FLAG_ERRMI: DCMI Synchronization error masked interrupt status DCMI_FLAG_VSYNCMI: DCMI VSYNC masked interrupt status DCMI_FLAG_LINEMI: DCMI Line masked interrupt status

Return values

The	state of FLAG.
