Hi Mark,

thanks for confirming this!

Cheers,

Yes, that is correct.  Each NDArray callbacks is done with a different asyn "addr".  So the plugin must pass the flag ASYN_MULTIDEVICE in the constructor and downstream plugins must subscribe for callbacks using the appropriate "addr".

This is a search to see what plugins call doCallbacksGenericPointer with a non-zero final argument:

NDPluginCircularBuff.cpp:              doCallbacksGenericPointer(preBuffer_->readFromStart(), NDArrayData, 0);
NDPluginCircularBuff.cpp:                doCallbacksGenericPointer(preBuffer_->readNext(), NDArrayData, 0);
NDPluginCircularBuff.cpp:          doCallbacksGenericPointer(pArrayCpy, NDArrayData, 0);
NDPluginColorConvert.cpp:    doCallbacksGenericPointer(this->pArrays[0], NDArrayData, 0);
NDPluginFFT.cpp:    doCallbacksGenericPointer(pArrayOut, NDArrayData, 0);
NDPluginFile.cpp:    doCallbacksGenericPointer(pArray, NDArrayData, 0);
NDPluginFile.cpp:      doCallbacksGenericPointer(pArrayOut, NDArrayData, 0);
NDPluginOverlay.cpp:    doCallbacksGenericPointer(this->pArrays[0], NDArrayData, 0);
NDPluginProcess.cpp:        doCallbacksGenericPointer( pArrayOut, NDArrayData, 0);
NDPluginROI.cpp:    doCallbacksGenericPointer(this->pArrays[0], NDArrayData, 0);
NDPluginROIStat.cpp:      doCallbacksGenericPointer(pArrayOut, NDArrayData, 0);
NDPluginStats.cpp:            doCallbacksGenericPointer(pArrayOut, NDArrayData, 0);
NDPluginTimeSeries.cpp:    doCallbacksGenericPointer(pArrayOut, NDArrayData, numSignals_);
NDPluginTimeSeries.cpp:      doCallbacksGenericPointer(pArray, NDArrayData, signal);
NDPluginTransform.cpp:  doCallbacksGenericPointer(transformedArray, NDArrayData,0);
NDPosPlugin.cpp:      doCallbacksGenericPointer(this->pArrays[0], NDArrayData, 0);

So of the standard plugins in ADCore only NDPluginTimeSeries does this.

Hi,

I would like to have a single input array into areaDetector plugin and have the plugin deliver multiple arrays as output. Is this possible? Are there any examples?
I would then like to feed the output arrays into other areaDetector plugins.

Thanks,
Hinko
