Stop ai manually

Hi everyone,

I am using the DAQ toolbox to build a negative feedback system. Anyhow, Is there any method to stop the ai by typing stop(ai); ? I want to stop the data acquisition by hand instead of setting the SamplePerTrigger.

Thank you, Kay

Hi Kay,

This is possible. Here is some sample code:

ai = analoginpt(....);
% Add channels and set it up
% Use SamplesPerTrigger property to achieve this by setting it to Inf
ai.SamplesPerTrigger = Inf;

start(ai)
% This will continue unless a stop(ai) command is issued

Documentation link for SamplesPerTrigger

You may also want to refer to 'Continuous Acquisition Using Analog Input' demo in the documentation that covers the same scenario

when i type stop(ai), the program continued and ignored my command!

What i should do?

[Chirag Gupta]

I would suggest looking at the demo! Also, how are you running it? Can you post some sample code?

[Chirag Gupta]

After running the stop(ai) command, check the value of ai.Running

or isrunning(ai)
