Detailed Description

Driver for Dectris Pilatus pixel array detectors using their camserver server over TCP/IP socket.

Constructor & Destructor Documentation

pilatusDetector::pilatusDetector ( const char *  portName,
const char *  camserverPort,
int  maxSizeX,
int  maxSizeY,
int  maxBuffers,
size_t  maxMemory,
int  priority,
int  stackSize 
)

Constructor for Pilatus 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 for the parameters defined in this class, asynNDArrayDriver, and ADDriver.

Parameters:
[in] portName The name of the asyn port driver to be created.
[in] camserverPort The name of the asyn port previously created with drvAsynIPPortConfigure to communicate with camserver.
[in] maxSizeX The size of the Pilatus detector in the X direction.
[in] maxSizeY The size of the Pilatus detector in the Y direction.
[in] portName The name of the asyn port driver to be created.
[in] maxBuffers The 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] maxMemory The 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] priority The thread priority for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.
[in] stackSize The stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.


Member Function Documentation

asynStatus pilatusDetector::drvUserCreate ( asynUser *  pasynUser,
const char *  drvInfo,
const char **  pptypeName,
size_t *  psize 
) [virtual]

Sets pasynUser->reason to one of the enum values for the parameters defined for this class if the drvInfo field matches one the strings defined for it.

If the parameter is not recognized by this class then calls ADDriver::drvUserCreate. Uses asynPortDriver::drvUserCreateParam.

Parameters:
[in] pasynUser pasynUser structure that driver modifies
[in] drvInfo String containing information about what driver function is being referenced
[out] pptypeName Location in which driver puts a copy of drvInfo.
[out] psize Location where driver puts size of param
Returns:
Returns asynSuccess if a matching string was found, asynError if not found.

Reimplemented from ADDriver.

void pilatusDetector::pilatusTask (  ) 

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

void pilatusDetector::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] fp File pointed passed by caller where the output is written to.
[in] details If >0 then driver details are printed.

Reimplemented from asynNDArrayDriver.

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

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

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

Parameters:
[in] pasynUser pasynUser structure that encodes the reason and address.
[in] value Value to write.

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

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

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

Parameters:
[in] pasynUser pasynUser structure that encodes the reason and address.
[in] value Value to write.

Reimplemented from ADDriver.

asynStatus pilatusDetector::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] pasynUser pasynUser structure that encodes the reason and address.
[in] value Address of the string to write.
[in] nChars Number of characters to write.
[out] nActual Number of characters actually written.

Reimplemented from asynNDArrayDriver.
