marCCD (const char *portName, const char *marCCDPort, int maxBuffers, size_t maxMemory, int priority, int stackSize) | |
Constructor for marCCD 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 | 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. | |

The marCCD program must be set into Acquire/Remote Control/Start to use this driver.

Constructor for marCCD 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.
[in] | portName | The name of the asyn port driver to be created. |
[in] | serverPort | The name of the asyn port driver previously created with drvAsynIPPortConfigure connected to the marccd_server program. |
[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 marCCD::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 marCCD::getImageDataTask | ( | ) |
This should be private but is called from C, must be public.
This task does the correction and file saving in the background, so that acquisition can be overlapped with these operations.
void marCCD::marCCDTask | ( | ) |
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 marCCD::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.
asynStatus marCCD::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. |
Reimplemented from ADDriver.
epicsEventId marCCD::stopEventId |
This should be private but is accessed from C, must be public.
