Detailed Description

Class that demonstrates the use of the asynPortDriver base class to greatly simplify the task of writing an asyn port driver.

This class does a simple simulation of a digital oscilloscope. It computes a waveform, computes statistics on the waveform, and does callbacks with the statistics and the waveform data itself. I have made the methods of this class public in order to generate doxygen documentation for them, but they should really all be private.

Constructor & Destructor Documentation

◆ testAsynPortDriver()

testAsynPortDriver::testAsynPortDriver ( const char *  portName,
int  maxPoints 
)

Constructor for the testAsynPortDriver class.

Calls constructor for the asynPortDriver base class.

Parameters
[in]portNameThe name of the asyn port driver to be created.
[in]maxPointsThe maximum number of points in the volt and time arrays

Member Function Documentation

◆ readEnum()

asynStatus testAsynPortDriver::readEnum ( asynUser *  pasynUser,
char *  strings[],
int  values[],
int  severities[],
size_t  nElements,
size_t *  nIn 
)
virtual

Called when asyn clients call pasynEnum->read().

The base class implementation simply prints an error message. Derived classes may reimplement this function if required.

Parameters
[in]pasynUserpasynUser structure that encodes the reason and address.
[in]stringsArray of string pointers.
[in]valuesArray of values
[in]severitiesArray of severities
[in]nElementsSize of value array
[out]nInNumber of elements actually returned

Reimplemented from asynPortDriver.

◆ readFloat64Array()

asynStatus testAsynPortDriver::readFloat64Array ( asynUser *  pasynUser,
epicsFloat64 *  value,
size_t  nElements,
size_t *  nIn 
)
virtual

Called when asyn clients call pasynFloat64Array->read().

Returns the value of the P_Waveform or P_TimeBase arrays.

Parameters
[in]pasynUserpasynUser structure that encodes the reason and address.
[in]valuePointer to the array to read.
[in]nElementsNumber of elements to read.
[out]nInNumber of elements actually read.

Reimplemented from asynPortDriver.

◆ simTask()

void testAsynPortDriver::simTask ( void  )

Simulation task that runs as a separate thread.

When the P_Run parameter is set to 1 to rub the simulation it computes a 1 kHz sine wave with 1V amplitude and user-controllable noise, and displays it on a simulated scope. It computes waveforms for the X (time) and Y (volt) axes, and computes statistics about the waveform.

◆ writeFloat64()

asynStatus testAsynPortDriver::writeFloat64 ( asynUser *  pasynUser,
epicsFloat64  value 
)
virtual

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

This function sends a signal to the simTask thread if the value of P_UpdateTime has changed. For all parameters it sets the value in the parameter library and calls any registered callbacks.

Parameters
[in]pasynUserpasynUser structure that encodes the reason and address.
[in]valueValue to write.

Reimplemented from asynPortDriver.

◆ writeInt32()

asynStatus testAsynPortDriver::writeInt32 ( asynUser *  pasynUser,
epicsInt32  value 
)
virtual

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

This function sends a signal to the simTask thread if the value of P_Run has changed. For all parameters it sets the value in the parameter library and calls any registered callbacks..

Parameters
[in]pasynUserpasynUser structure that encodes the reason and address.
[in]valueValue to write.

Reimplemented from asynPortDriver.
