Resumes multiple channels of acquisition on the selected
DAQs.
DAQflush on page 54 Flushes the acquisition buffers and resets the acquisition
counter included in a data acquisition block.
DAQflushMultiple on page 55 Flushes the acquisition buffers and resets the acquisition
counter included in a Data Acquisition block.
DAQtrigger on page 56 Triggers the acquisition of words in the selected DAQs
provided that they are configured for VI/HVI Trigger.
DAQtriggerMultiple on page 57 Triggers the acquisition of words in the selected DAQ provided
that they are configured for VI/HVI Trigger.
DAQcounterRead on page 58 Returns the number of available points to be read from the
intermediate buffer.
triggerIOconfig on page 59 Configures the trigger connector/line direction.
triggerIOwrite on page 60 Sets the trigger output and synchronization mode.
triggerIOread on page 61 Reads the trigger input I/O Triggers.
clockSetFrequency on page 62 Sets the module clock frequency.
clockGetFrequency on page 63 Returns the real hardware clock frequency.
clockGetSyncFrequency on page 64 Returns the frequency of the synchronization clock.
clockResetPhase on page 65 Sets the module in a synchronized state, waiting for the first
trigger to reset the phase of the internal clocks CLKsync and
CLKsys.
DAQbufferPoolConfig on page 66 Configures buffer pool that will be filled with the data of the
channel to be transferred to PC.
DAQbufferAdd on page 68 Adds an additional buffer to the channel’s previously
configured pool.
DAQbufferGet on page 69 Retrieves a filled buffer from the channel buffer pool. You have
to call DAQbufferAdd with this buffer so the buffer can be used
again.
DAQbufferPoolRelease on page 70 Releases the channel buffer pool and its resources. After this
function is called, you need to call DAQbufferRemove
consecutively to get all buffers back and release them.
DAQbufferRemove on page 71 Requests that a buffer be removed from the channel buffer
pool. If a NULL pointer is returned, no more buffers remain in
the buffer pool. Returned buffer is a previously added buffer
from the user and the user has to release/delete it.
FFT on page 72 Calculates the FFT of data captured by DAQread for the
selected channel. FFT frequency range goes from 0 to fs/2.
