I want to add one Continuous function in Producer consumer event??

[AnkitRamani]

Hello,

producer consumer event vi is base example for me ,I have design my system according to it.

Now I am dealing with photo sensor in that its measure continuous data according to intensity of light,for continuous function I have make while structure for photo sensor but the problem is that I don't know how to add this while loop in producer consumer event ,if I add then its run continuously and then my operation is stuck there.

Will you please guide me that how can I add this continuous function in this structure so simultaneously I can do other function like pause reset..Etc...

Here in attachment I have attaché one example regarding to this in that I have add simply increment function in case structure and when I execute my vi then execution is stuck at while loop until it manually stop.

Thank you very much...

What you want is Producer/Consumer (data). Perhaps a combination of both.  If you have user events so that you need the event structure, add a third loop to be the data acquisition producer.

You would have three loops: Producer (Events) for the User Interface, Producer (Data) for data acquisition, and Consumer.  Two different queues are require, one for each Producer.  You might be able to make it work with one but it is so much easier with two. Also plan how you will shut down the loops.  The "kill the queue" technique used by the Design Pattern does not work because the DAQ queue is not in the Event Producer. Also you need to close the data acquisition before stopping the Data Producer.  A notifier is one way of letting all loops know of the shutdown command.

Hi AnkitRamani,

I made a simple example with a UI queue and a second producer which is pushing data into its own consumer, displaying the signal and its spectrum.

Maybe this is what u need.
