Function Documentation

void DCMI_ClearFlag

(

uint16_t

DCMI_FLAG

)

Clears the DCMI's pending flags.

Parameters

DCMI_FLAG,:

specifies the flag to clear. This parameter can be any combination of the following values: DCMI_FLAG_FRAMERI: Frame capture complete Raw flag mask DCMI_FLAG_OVFRI: Overflow Raw flag mask DCMI_FLAG_ERRRI: Synchronization error Raw flag mask DCMI_FLAG_VSYNCRI: VSYNC Raw flag mask DCMI_FLAG_LINERI: Line Raw flag mask

Return values

None

void DCMI_ClearITPendingBit

(

uint16_t

DCMI_IT

)

Clears the DCMI's interrupt pending bits.

Parameters

DCMI_IT,:

specifies the DCMI interrupt pending bit to clear. 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

Return values

None

FlagStatus DCMI_GetFlagStatus

(

uint16_t

DCMI_FLAG

)

Checks whether the DCMI interface flag is set or not.

Parameters

DCMI_FLAG,:

specifies the flag to check. This parameter can be one of the following values: DCMI_FLAG_FRAMERI: Frame capture complete Raw flag mask DCMI_FLAG_OVFRI: Overflow Raw flag mask DCMI_FLAG_ERRRI: Synchronization error Raw flag mask DCMI_FLAG_VSYNCRI: VSYNC Raw flag mask DCMI_FLAG_LINERI: Line Raw flag mask DCMI_FLAG_FRAMEMI: Frame capture complete Masked flag mask DCMI_FLAG_OVFMI: Overflow Masked flag mask DCMI_FLAG_ERRMI: Synchronization error Masked flag mask DCMI_FLAG_VSYNCMI: VSYNC Masked flag mask DCMI_FLAG_LINEMI: Line Masked flag mask DCMI_FLAG_HSYNC: HSYNC flag mask DCMI_FLAG_VSYNC: VSYNC flag mask DCMI_FLAG_FNE: Fifo not empty flag mask

Return values

The	new state of DCMI_FLAG (SET or RESET).

ITStatus DCMI_GetITStatus

(

uint16_t

DCMI_IT

)

Checks whether the DCMI interrupt has occurred or not.

Parameters

DCMI_IT,:

specifies the DCMI interrupt source to check. This parameter can be one 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

Return values

The	new state of DCMI_IT (SET or RESET).

void DCMI_ITConfig	(	uint16_t	DCMI_IT,
		FunctionalState	NewState
	)

Enables or disables the DCMI interface interrupts.

Parameters

DCMI_IT,:	specifies the DCMI interrupt sources to be enabled or disabled. 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
NewState,:	new state of the specified DCMI interrupts. This parameter can be: ENABLE or DISABLE.

Return values

None
