AIAcquireWaveforms

[Phil_H]

We are in the process of upgrading to version 7.1, and we are having problems with a call to the AIAcquireWaveforms function. This function call is currently in an old library file we have inherited, but as far as we can tell, this function is now obsolete.

Is there an equivalent function we can use to replace this function?  I have looked in the documentation, but I have not been able to find any help on replacing this function with an equivalent.

Hi Phil,

  the AIAcquireWaveforms is a traditional DAQ function. If you've just upgraded, you may have not installed the traditional DAQ driver.

Can you check in measurement and automation explorer under the software section for which version of the driver you have installed.

Also, if you've just upgraded LabVIEW, you also need to re-install the DAQ driver. You can tell this if there isn't any daq functions in LabVIEW, but measurement and automation explorer says daq is installed.

The order of installation is always Environment, drivers, hardware.

and for DAQmx (the newer driver api) is here
