Detailed Description

Base class for asyn port drivers; handles most of the bookkeeping for writing an asyn port driver with standard asyn interfaces and a parameter library.

Constructor & Destructor Documentation

◆ asynPortDriver() [1/2]

asynPortDriver::asynPortDriver ( const char *  portNameIn,
int  maxAddrIn,
int  interfaceMask,
int  interruptMask,
int  asynFlags,
int  autoConnect,
int  priority,
int  stackSize 
)

Constructor for the asynPortDriver class.

Parameters
[in]portNameInThe name of the asyn port driver to be created.
[in]maxAddrInThe maximum number of asyn addr addresses this driver supports. Often it is 1 (which is the minimum), but some drivers, for example a 16-channel D/A or A/D would support values > 1. This controls the number of parameter tables that are created.
[in]interfaceMaskBit mask defining the asyn interfaces that this driver supports. The bit mask values are defined in asynPortDriver.h, e.g. asynInt32Mask.
[in]interruptMaskBit mask definining the asyn interfaces that can generate interrupts (callbacks). The bit mask values are defined in asynPortDriver.h, e.g. asynInt8ArrayMask.
[in]asynFlagsFlags when creating the asyn port driver; includes ASYN_CANBLOCK and ASYN_MULTIDEVICE.
[in]autoConnectThe autoConnect flag for the asyn port driver. 1 if the driver should autoconnect.
[in]priorityThe thread priority for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags. If it is 0 then the default value of epicsThreadPriorityMedium will be assigned by asynManager.
[in]stackSizeThe stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags. If it is 0 then the default value of epicsThreadGetStackSize(epicsThreadStackMedium) will be assigned by asynManager.

◆ asynPortDriver() [2/2]

asynPortDriver::asynPortDriver ( const char *  portNameIn,
int  maxAddrIn,
int  paramTableSize,
int  interfaceMask,
int  interruptMask,
int  asynFlags,
int  autoConnect,
int  priority,
int  stackSize 
)

Legacy constructor for the asynPortDriver class (DEPRECATED - please use the one above instead).

asynPortDriver >=R4-32 handles the table size automatically. Thus the paramTableSize parameter has been removed from the constructor. This constructor is provided for backwards compatibility. Users should switch to using the constructor ASAP.

◆ ~asynPortDriver()

asynPortDriver::~asynPortDriver ( )
virtual

Destructor for asynPortDriver class; frees resources allocated when port driver is created.

[in]maskInterrupt mask.

◆ clearUInt32DigitalInterrupt() [1/2]

asynStatus asynPortDriver::clearUInt32DigitalInterrupt ( int  index,
epicsUInt32  mask 
)
virtual

Clears the interrupt mask in the parameter library Calls paramList::clearUInt32Interrupt (0, index, mask) i.e.

for parameter list 0.

Parameters
[in]indexThe parameter number
[in]maskInterrupt mask.

◆ clearUInt32DigitalInterrupt() [2/2]

asynStatus asynPortDriver::clearUInt32DigitalInterrupt ( int  list,
int  index,
epicsUInt32  mask 
)
virtual

Clears the interrupt mask in the parameter library Calls paramList::clearUInt32Interrupt (index, mask) for the parameter list indexed by list.

Parameters
[in]listThe parameter list number. Must be < maxAddr passed to asynPortDriver::asynPortDriver.
[in]indexThe parameter number
[in]maskInterrupt mask.

◆ connect()

Connects driver to device; The base class implementation simply calls pasynManager->exceptionConnect if address is valid Derived classes can reimplement this function for real connection management.

Parameters
[in]pasynUserThe pasynUser structure which contains information about the port and address

Reimplemented in FastCCD, prosilica, and ADLambda.

◆ createParam() [1/2]

asynStatus asynPortDriver::createParam ( const char *  name,
asynParamType  type,
int *  index 
)
virtual

Creates a parameter in the parameter library.

Calls paramList::createParam (list, name, index) for all parameters lists.

Parameters
[in]nameParameter name
[in]typeParameter type
[out]indexParameter number

◆ createParam() [2/2]

asynStatus asynPortDriver::createParam ( int  list,
const char *  name,
asynParamType  type,
int *  index 
)
virtual

Creates a parameter in the parameter library.

Calls paramList::addParam (name, index) for the parameter list indexed by list.
