Inheritance diagram for SeestarCCD:

Public Member Functions
	SeestarCCD ()
	Main entry point - INDI handles this through the unique_ptr.
virtual	~SeestarCCD ()=default
virtual const char *	getDefaultName () override
virtual bool	initProperties () override
	Initialize properties initial state and value. The child class must implement this function.
virtual bool	Connect () override
	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.
virtual bool	updateProperties () override
	updateProperties is called whenever there is a change in the CONNECTION status of the driver. This will enable the driver to react to changes of switching ON/OFF a device. For example, a driver may only define a set of properties after a device is connected, but not before.
virtual int	SetTemperature (double temperature) override
	Set CCD temperature.
virtual std::string	buildAlpacaFormData (const nlohmann::json &request) override
	Build Alpaca form data with Seestar-specific parameter ordering.
Public Member Functions inherited from AlpacaCCD
	AlpacaCCD ()
virtual	~AlpacaCCD ()=default
void	ISGetProperties (const char *dev) override
	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.
virtual bool	ISNewText (const char *dev, const char *name, char *texts[], char *names[], int n) override
	Process the client newSwitch command.
virtual bool	ISNewNumber (const char *dev, const char *name, double values[], char *names[], int n) override
	Process the client newNumber command.

Detailed Description

The SeestarCCD class provides Seestar specific workarounds for the ASCOM Alpaca CCD driver.

The Seestar CCD has bugs in its ImageBytes protocol implementation:

1. Rank is stored in Dimension1 field instead of Rank field
2. Width is stored in Dimension3 field instead of Dimension1
3. Height is correct in Dimension2
4. TransmissionElementType reports Int32 (2) but actually sends Int16 data
5. DataStart reports 0 but should be 44

This driver applies workarounds to correctly interpret Seestar images.

Member Function Documentation

buildAlpacaFormData()

std::string SeestarCCD::buildAlpacaFormData ( const nlohmann::json &  request )

overridevirtual

Build Alpaca form data with Seestar-specific parameter ordering.

Seestar requires method parameters BEFORE ClientID/ClientTransactionID (opposite of standard Alpaca ordering)

Reimplemented from AlpacaCCD.

Definition at line 123 of file indi_seestar_ccd.cpp.

Connect()

bool SeestarCCD::Connect ( )

overridevirtual

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 AlpacaCCD.

Definition at line 76 of file indi_seestar_ccd.cpp.

getDefaultName()

const char * SeestarCCD::getDefaultName ( )

overridevirtual

Returns

Default name of the device.

Reimplemented from AlpacaCCD.

Definition at line 49 of file indi_seestar_ccd.cpp.

initProperties()

bool SeestarCCD::initProperties ( )

overridevirtual

Initialize properties initial state and value. The child class must implement this function.

Returns

True if initialization is successful, false otherwise.

Reimplemented from AlpacaCCD.

Definition at line 57 of file indi_seestar_ccd.cpp.

parseImageBytesMetadata()

bool SeestarCCD::parseImageBytesMetadata ( ImageBytesMetadata *  metadata, size_t  body_size  )

overrideprotectedvirtual

Parse ImageBytes metadata with Seestar-specific workarounds.

Overrides the base class method to apply Seestar quirk fixes:

• Swap dimension fields to correct locations
• Force Int16 element type regardless of what's reported
• Fix DataStart offset

Parameters

metadata	Pointer to ImageBytesMetadata structure (will be modified)
body_size	Total size of HTTP response body

Returns

true if metadata is valid after corrections

Reimplemented from AlpacaCCD.

Definition at line 163 of file indi_seestar_ccd.cpp.

SetTemperature()

int SeestarCCD::SetTemperature ( double  temperature )

overridevirtual

Set CCD temperature.

Parameters

temperature

CCD temperature in degrees celcius.

Returns

0 or 1 if setting the temperature call to the hardware is successful. -1 if an error is encountered. Return 0 if setting the temperature to the requested value takes time. Return 1 if setting the temperature to the requested value is complete.

Note

Upon returning 0, the property becomes BUSY. Once the temperature reaches the requested value, change the state to OK.

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

Reimplemented from AlpacaCCD.

Definition at line 113 of file indi_seestar_ccd.cpp.

updateProperties()

bool SeestarCCD::updateProperties ( )

overridevirtual

updateProperties is called whenever there is a change in the CONNECTION status of the driver. This will enable the driver to react to changes of switching ON/OFF a device. For example, a driver may only define a set of properties after a device is connected, but not before.

Returns
