Constructor & Destructor Documentation

tcBufferedCameraLinkIO()

tcBufferedCameraLinkIO::tcBufferedCameraLinkIO	(	tcSensorBoard *	apSensor,
		int32	anCamLinkFPGAControlAddress,
		uint32	anSgdmaCtrlAddr,
		uint32	anSgdmaDescAddr,
		uint32	anRespRegAddr,

		uint32	anPacketizerAddr,
		tcPllReconfig *	apReconfig = NULL
	)

Creates a CameraLink component that has a SGDMA engine attached for slow trickling out of RAM. Essentially, this means there are two modes of operation depending on the capture request:

1) Continuous capture (ie: <STRT>) stream directly through the CameraLink component. 2) Captures with a parameter (ie: <STRT 47>) will cause the capture to stream to RAM and when complete, this component will kick the SGDMA engine to trickle the data out the CameraLink component.

Member Function Documentation

alwaysBuffer()

void SocCamera::tcBufferedCameraLinkIO::alwaysBuffer

(

int

anAlwaysBuffer

)

capture()

teNackCode tcBufferedCameraLinkIO::capture ( tsCaptureRequest  asRequest )

virtual

Start a capture with this request. If the request's number of frames is tsNewRequest::CANCEL_CAPTURE then the current capture is stopped if possible.

Parameters

asRequest

- the request for capture being made.

Returns

a nack code if the capture parameters are inelligable for this IOChannel.

Reimplemented from tcCameraLinkIO.

registerWatcher()

void SocCamera::tcBufferedCameraLinkIO::registerWatcher

(

tcBufferedCameraLinkWatcher *

apWatcher

)

sendUpdate()

void tcBufferedCameraLinkIO::sendUpdate ( tsNewFrameMsg *  apMsg )

virtual

If this is called, a stream into memory is complete. This will then kick the SGDMA engine to transfer out of memory through the CameraLink component.

Parameters

apMsg

- the update message.

Reimplemented from tcCameraLinkIO.

setBpp()

SocCamera::teNackCode SocCamera::tcBufferedCameraLinkIO::setBpp ( SocCamera::teBPPMode  aeBppMode )

virtual

Sets the bits-per-pixel output of the camera.

Parameters

aeBppMode

- the bits per pixel mode.

Returns

the nack code for the operation

Reimplemented from tcCameraLinkIO.

setOutputMode()

SocCamera::teNackCode SocCamera::tcBufferedCameraLinkIO::setOutputMode ( tcCameraLinkIO::teOutputMode  aeOutputMode )

virtual

Toggles between the various camera link output modes (expanded, base).

Parameters

aeOutputMode

- the mode to move into.

Returns

a nack code if the output mode is not supported.

Reimplemented from tcCameraLinkIO.

unregisterWatcher()

void SocCamera::tcBufferedCameraLinkIO::unregisterWatcher

(

tcBufferedCameraLinkWatcher *

apWatcher

)
