acquire data without sampling rate using DAQ?

[akv103]

Is there any way to acquire data using DAQ without sampling rate?

[Tepig]

Are you looking for this example?

C:\Program Files\National Instruments\LabVIEW 201x\examples\DAQmx\Analog Input\Voltage - SW-Timed Input.vi

Could you please post that link?

In that channel settings, is that possible to add physical channels instead of 1?

Dev1/ai0:2

or

Dev1/ai0, Dev1/ai3

I cannot understand why do you want the link.

It's just file path.

In LabVIEW, open the Example Finder (Help->Find Examples).  Look through the DAQmx->Analog Input and you will find this example.

In that also have to specify the sampling rate in "Acquire data" section.

Is there any alternative for this?

I need to acquire 2 channels of input from DAQ without specifying sampling rate.

Is there any solution for this?

Hi vim,

In that also have to specify the sampling rate in "Acquire data" section.

No, that example does NOT ask for a (DAQmx) sample rate!

It asks for the loop iteration rate (aka loop time): that's how the example works.

You can learn from that example on how to setup a DAQmx task and read samples without setting an explicit sample rate. Adapt with your own algorithm: apparently you want to read more than just one sample, so you will employ a loop with a certain loop iteration rate!
