roper (const char *portName, int maxBuffers, size_t maxMemory, int priority, int stackSize) | |
Constructor for Roper driver; most parameters are simply passed to ADDriver::ADDriver. | |
virtual asynStatus | writeInt32 (asynUser *pasynUser, epicsInt32 value) |
Called when asyn clients call pasynInt32->write(). | |
virtual asynStatus | writeFloat64 (asynUser *pasynUser, epicsFloat64 value) |
Called when asyn clients call pasynFloat64->write(). | |
virtual void | setShutter (int open) |
Set the shutter position. | |
virtual asynStatus | drvUserCreate (asynUser *pasynUser, const char *drvInfo, const char **pptypeName, size_t *psize) |
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. | |
void | report (FILE *fp, int details) |
Report status of the driver. | |
void | roperTask () |
This thread computes new image data and does the callbacks to send it to higher layers. |
Version 2.5.22 or later of those programs is required.
roper::roper | ( | const char * | portName, | |
int | maxBuffers, | |||
size_t | maxMemory, | |||
int | priority, | |||
int | stackSize | |||
) |
Constructor for Roper 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.
[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. |
asynStatus roper::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.
[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 |
Reimplemented from ADDriver.
void roper::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.
[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.
void roper::roperTask | ( | ) |
This thread computes new image data and does the callbacks to send it to higher layers.
void roper::setShutter | ( | int | open | ) | [virtual] |
Set the shutter position.
This method will open (1) or close (0) the shutter if ADShutterMode==ADShutterModeEPICS. Drivers will implement setShutter if they support ADShutterModeDetector. If ADShutterMode=ADShutterModeDetector they will control the shutter directly, else they will call this method.
[in] | open | 1 (open) or 0 (closed) |
Reimplemented from ADDriver.
asynStatus roper::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..
[in] | pasynUser | pasynUser structure that encodes the reason and address. |
[in] | value | Value to write. |
asynStatus roper::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..
[in] | pasynUser | pasynUser structure that encodes the reason and address. |
[in] | value | Value to write. |
