How can I set trigger callback function for session based interface?

Hi,

I want to callback some functions when trigger is executed in DAQ session based interface.

How can I set it? I tried to execute >> set(AI,'TriggerFcn',@show_data); but matlab says "TriggerFcn is not an accessable property for 'daq.ni.Session'". The instrument is NI USB-6251 and Matlab version is R2013b.

Sincerely yours

Has anyone looked into this int he past 9 months? This is essentially capabilities that existed in the past and were removed.

Add a listener for DataAvailable? See here and an example of someone using it over there

Thank you. I successfully add a listener for DataAvailable. I finally found that session based functions are very convenient.

If I solved the problem, please mark my answer as Accepted.

I would like to second this question. This is functionality that existed in the legacy based interface and was removed in the session-based interface. I don't know how to convert my old code to this now.

Dear Mr.Yishai

Thank you. I see callback was removed in the session-based interface. Can anyone answer our question?
