Detailed Description

Driver for Photonic Sciencies Ltd.

CCD detector; communicates with the PSL servr over a TCP/IP socket. The server must be started with the PSL Software Menu/Connexion.


Constructor & Destructor Documentation

PSL::PSL ( const char *  portName,
const char *  serverPort,
int  maxBuffers,
size_t  maxMemory,
int  priority,
int  stackSize 
)

Constructor for PSL driver; most parameters are simply passed to ADDriver::ADDriver.

After calling the base class constructor this method creates a thread to collect the detector data, and sets reasonable default values the parameters defined in this class, asynNDArrayDriver, and ADDriver.

Parameters:
[in]portNameThe name of the asyn port driver to be created.
[in]serverPortThe name of the asyn port driver previously created with drvAsynIPPortConfigure connected to the PSL_server program.
[in]maxBuffersThe maximum number of NDArray buffers that the NDArrayPool for this driver is allowed to allocate. Set this to -1 to allow an unlimited number of buffers.
[in]maxMemoryThe maximum amount of memory that the NDArrayPool for this driver is allowed to allocate. Set this to -1 to allow an unlimited amount of memory.
[in]priorityThe thread priority for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.
[in]stackSizeThe stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.

Member Function Documentation

void PSL::PSLTask ( )

This should be private but is called from C, must be public.

This thread controls acquisition, reads TIFF files to get the image data, and does the callbacks to send it to higher layers.

void PSL::report ( FILE *  fp,
int  details 
) [virtual]

Report status of the driver.

Prints details about the driver if details>0. It then calls the ADDriver::report() method.

Parameters:
[in]fpFile pointed passed by caller where the output is written to.
[in]detailsIf >0 then driver details are printed.

Reimplemented from asynNDArrayDriver.

asynStatus PSL::writeFloat64 ( asynUser *  pasynUser,
epicsFloat64  value 
) [virtual]

Called when asyn clients call pasynFloat64->write().

This function performs actions for some parameters. For all parameters it sets the value in the parameter library and calls any registered callbacks..

Parameters:
[in]pasynUserpasynUser structure that encodes the reason and address.
[in]valueValue to write.

Reimplemented from asynPortDriver.

asynStatus PSL::writeInt32 ( asynUser *  pasynUser,
epicsInt32  value 
) [virtual]

Called when asyn clients call pasynInt32->write().

This function performs actions for some parameters, including ADAcquire, ADBinX, etc. For all parameters it sets the value in the parameter library and calls any registered callbacks..

Parameters:
[in]pasynUserpasynUser structure that encodes the reason and address.
[in]valueValue to write.

Reimplemented from ADDriver.

asynStatus PSL::writeOctet ( asynUser *  pasynUser,
const char *  value,
size_t  nChars,
size_t *  nActual 
) [virtual]

Called when asyn clients call pasynOctet->write().

This function performs actions for some parameters, including PilatusBadPixelFile, ADFilePath, etc. For all parameters it sets the value in the parameter library and calls any registered callbacks..

Parameters:
[in]pasynUserpasynUser structure that encodes the reason and address.
[in]valueAddress of the string to write.
[in]nCharsNumber of characters to write.
[out]nActualNumber of characters actually written.

Reimplemented from asynNDArrayDriver.
