CameraController Class

Namespace: GHIElectronics.TinyCLR.Devices.Camera · Assembly: GHIElectronics.TinyCLR.Devices.Camera

Represents a DCMI / parallel camera interface. Configure timing via SetActiveSettings, Enable the capture engine, then call Capture(byte[], int) to read a frame into a buffer.

public class CameraController : IDisposable

Properties

Provider

public ICameraControllerProvider Provider { get; }

The low-level provider backing this controller.

Methods

GetDefault()

public static CameraController GetDefault()

Returns the default camera controller for this device.

Returns CameraController

FromName(string name)

public static CameraController FromName(string name)

Returns a camera controller identified by its native API name.

Parameter	Type	Description
name	string

Returns CameraController

FromProvider(ICameraControllerProvider provider)

public static CameraController FromProvider(ICameraControllerProvider provider)

Creates a controller from a custom ICameraControllerProvider.

Parameter	Type	Description
provider	ICameraControllerProvider

Returns CameraController

Dispose()

public void Dispose()

Releases the underlying provider.

SetActiveSettings(CaptureRate captureRate, bool horizontalSyncPolarity, bool verticalSyncPolarity, bool pixelClockPolarity, SynchronizationMode synchronizationMode, ExtendedDataMode extendedDataMode, uint sourceClock)

public void SetActiveSettings(CaptureRate captureRate, bool horizontalSyncPolarity, bool verticalSyncPolarity, bool pixelClockPolarity, SynchronizationMode synchronizationMode, ExtendedDataMode extendedDataMode, uint sourceClock)

Applies a complete set of DCMI timing/protocol settings.

Parameter	Type	Description
captureRate	CaptureRate	Per-frame capture rate.
horizontalSyncPolarity	bool	HSYNC polarity (false = active low).
verticalSyncPolarity	bool	VSYNC polarity (false = active low).
pixelClockPolarity	bool	Pixel-clock polarity (false = falling-edge sample).
synchronizationMode	SynchronizationMode	Hardware vs. embedded synchronization.
extendedDataMode	ExtendedDataMode	Data bus width.
sourceClock	uint	Source clock feeding the camera, in Hz.

Capture(byte[] data, int timeoutMillisecond)

public int Capture(byte[] data, int timeoutMillisecond)

Captures one frame into the supplied buffer.

Parameter	Type	Description
data	byte[]	Destination buffer. Must be large enough for one frame at the configured resolution/format.
timeoutMillisecond	int	Maximum time to wait for the frame, in milliseconds.

Returns int — Number of bytes actually captured.

Capture(byte[] data, int offset, int count, int timeoutMillisecond)

public int Capture(byte[] data, int offset, int count, int timeoutMillisecond)

Captures one frame into a slice of the buffer.

Parameter	Type	Description
data	byte[]
offset	int
count	int
timeoutMillisecond	int

Returns int

Enable()

public void Enable()

Powers on the capture engine.

Disable()

public void Disable()

Powers off the capture engine.
