Stream vs Digital Single/Multiple Writer/Reader APIs

[angelmcdoggie]

Dear All,

CNiDAQmxTask::Stream  vs CNiDAQmxDigitalSingleChannelWriter::WriteSingleSampleMultiLine()  OR

CNiDAQmxDigitalSingleChannelReader::ReadSingleSampleMultiLine()  [and other variation of these APIs]

I am aware that these two function deal with reading and writing sample/s.

Please explain the difference between two functions (green vs blue) in terms of behaviour.

Is there a general rule or guideline regarding the usage?

Thanks,

A

Hi A,

CNiDAQmxTask::Stream exposes a data stream on a CNiDAQmxTask that can be used to control reading and writing behavior and can be used in conjunction with reader and writer classes to read or write samples to or from a DAQmx task. This class is a sub-object of CNiDAQmxTask.

For specific definitions of these different methods and declarations, refer to the DAQmx .NET Framework 2.0 Help found in you Start Menu under National Instruments » NI-DAQ. Here you can find the specific classes of interest and associations.
