bool initProperties () override
 Initilize properties initial state and value. The child class must implement this function. More...
 
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. More...
 
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. More...

Detailed Description

The CCDSim class provides an advanced simulator for a CCD that includes a dedicated on-board guide chip.

The CCD driver can generate star fields given that General-Star-Catalog (gsc) tool is installed on the same machine the driver is running.

Many simulator parameters can be configured to generate the final star field image. In addition to support guider chip and guiding pulses (ST4), a filter wheel support is provided for 8 filter wheels. Cooler and temperature control is also supported.

The driver can snoop the mount equatorial coords to draw the star field. It listens to EQUATORIAL_PE property and also defines it so that the user can set it manually.

Video streaming can be enabled from the Stream property group with several encoders and recorders supported.

bool CCDSim::UpdateCCDBin ( int  hor,
int  ver 
)
overrideprotectedvirtual

CCD calls this function when CCD Binning needs to be updated in the hardware. Derived classes should implement this function.

Parameters
horHorizontal binning.
verVertical binning.
Returns
true is CCD chip update is successful, false otherwise.
Note
This function is not implemented in CCD, it must be implemented in the child class

Reimplemented from INDI::CCD.

bool CCDSim::UpdateCCDFrame ( int  x,
int  y,
int  w,
int  h 
)
overrideprotectedvirtual

CCD calls this function when CCD Frame dimension needs to be updated in the hardware. Derived classes should implement this function.

Parameters
xSubframe X coordinate in pixels.
ySubframe Y coordinate in pixels.
wSubframe width in pixels.
hSubframe height in pixels.
Note
(0,0) is defined as most left, top pixel in the subframe.
Returns
true is CCD chip update is successful, false otherwise.
Note
This function is not implemented in CCD, it must be implemented in the child class

bool CCDSim::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
True if update is successful, false otherwise.

Reimplemented from INDI::CCD.
