Available: Yes
3. 3. 2. 4 DAQconfig
Configures the acquisition of words Data Acquisition (DAQs) in two possible reading
modes:
Blocking: Using the function DAQread on page 44 to read the words. DAQread
is a blocking function that is released when the amount of words specified in
DAQpoints is acquired or when timeout elapses. This mode is enabled when a
callback function is not specified (it is set to null).
Non-blocking: The user specifies a callback function which is called whenever
the DAQeventDataReady event is signaled or when
timeout elapses. In the latter condition, there may be words available, but less than
the amount specified in DAQpoints.
Parameters
Name Description
Inputs
moduleID (Non-object-oriented languages only) Module identifier, returned by function
open on page 28
nDAQ DAQ to configure
triggerMode Trigger mode
triggerDelay (number of samples that trigger is delayed (or advanced if negative))
DAQpointsPerCycle Number of words to acquire per trigger
cycles Number of acquisition cycles. Each cycle requires a trigger specified by triggerMode.
A negative number means continuous acquisition
errorIn (LabVIEW only) If it contains an error, the function will not be executed and errorIn
will be passed to errorOut
Outputs
moduleIDout (LabVIEW only) A copy of moduleID
