apply a pulse at the STOPTRIG* input of the MIO-16/16D or the EXTTRIG* input of
the AT-MIO-16F-5, AT-MIO-64F-5, or AT-MIO-16X or the EXTTRIG input of Lab and
1200 Series devices, NI-DAQ acquires an additional number of data points specified by
ptsAfterStoptrig before the acquisition terminates.
DAQ_Check or Lab_ISCAN_Check will
rearrange the data into chronological order (from oldest to newest) and return with the status
parameters equal to one when called after termination.
Calling
DAQ_StopTrigger_Config with stopTrig set to 0 returns the acquisition mode to
its default, acyclical setting.
You cannot use pretrigger mode in conjunction with the external conversion method on the
MIO-16/16D devices.
(E Series devices only) If you use this function with stopTrig = 1, the device uses an active
high signal from the PFI1 pin as the stop trigger. This selection is consistent with the
MIO-16/16D boards. After calling this function, you can use the
Select_Signal function
to take advantage of the DAQ-STC signal routing and polarity selection features.
