◆ AbortExposure()

bool V4L2_Driver::AbortExposure ( )

protectedvirtual

Abort ongoing exposure.

Returns: true is abort is successful, false otherwise.

Note: This function is not implemented in CCD, it must be implemented in the child class

Reimplemented from INDI::CCD.

◆ allocateBuffers()

void V4L2_Driver::allocateBuffers ( )

protected

◆ Connect()

bool V4L2_Driver::Connect ( )

protectedvirtual

Connect to the device.

INDI::DefaultDevice implementation connects to appropriate connection interface (Serial or TCP) governed by connectionMode. If connection is successful, it proceed to call Handshake() function to ensure communication with device is successful. For other communication interface, override the method in the child class implementation

Returns: True if connection is successful, false otherwise

Reimplemented from INDI::DefaultDevice.

◆ Disconnect()

bool V4L2_Driver::Disconnect ( )

protectedvirtual

Disconnect from device.

Returns: True if successful, false otherwise

Reimplemented from INDI::DefaultDevice.

Returns: True if initilization is successful, false otherwise.

Reimplemented from INDI::CCD.

◆ ISGetProperties()

void V4L2_Driver::ISGetProperties ( const char * dev )

virtual

define the driver's properties to the client.

Usually, only a minimum set of properties are defined to the client in this function if the device is in disconnected state. Those properties should be enough to enable the client to establish a connection to the device. In addition to CONNECT/DISCONNECT, such properties may include port name, IP address, etc. You should check if the device is already connected, and if this is true, then you must define the remainder of the the properties to the client in this function. Otherwise, the remainder of the driver's properties are defined to the client in updateProperties() function which is called when a client connects/disconnects from a device.

Parameters

dev	name of the device

Note: This function is called by the INDI framework, do not call it directly. See LX200 Generic driver for an example implementation

Reimplemented from INDI::CCD.

bool V4L2_Driver::ISNewNumber	(	const char *	dev,
		const char *	name,
		double	values[],
		char *	names[],

	)

virtual

Process the client newNumber command.

Note: This function is called by the INDI framework, do not call it directly.

Returns: True if any property was successfully processed, false otherwise.

bool V4L2_Driver::ISNewSwitch	(	const char *	dev,
		const char *	name,
		ISState *	states,

		char *	names[],
		int	n
	)

virtual

Process the client newSwitch command.

Note: This function is called by the INDI framework, do not call it directly.
