mar345 (const char *portName, const char *mar345Port, int maxBuffers, size_t maxMemory, int priority, int stackSize) | |
Constructor for mar345 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. | |

The mar345dtb program must be running and must be configured to listen for commands on a socket. This is done by adding a line like the following to the file /home/mar345/tables/config.xxx (where xxx is the detector serial number) COMMAND PORT 5001 In this example 5001 is the TCP/IP port number that the mar345dtb and this driver will use to communicate.

Constructor for mar345 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 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 mar345dtb 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. |
[in] | stackSize | The stack size for the asyn port driver thread. |
asynStatus mar345::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 |

void mar345::mar345Task | ( | ) |
Should be private but accessed from C, must be public.
This thread controls handling of slow events - erase, acquire, change mode.
void mar345::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 mar345::writeInt32 | ( | asynUser * | pasynUser, | |
epicsInt32 | value | |||
) | [virtual] |
Called when asyn clients call pasynInt32->write().
This function performs actions for some parameters, including ADAcquire, mar345Erase, 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. |
