Background loop

[WesleyTaylor]

 Hello all,

I have managed to get a nice UIR where I press a button and it will open a com port, send a message, to configure the rs232 device downstream.

What I want to happen is to remove the need to initalise this by user interaction.

I want to have it automatically sending a constant message every 10 seconds.

Do I place a loop in the main or is there another parallel function i can run to loop through this comopenconfig, comwr, comrd. 

Regards,

Wes

I suggest you to examine the timer controls: the timer controls can be configured to fire a callback at regular intervals; inside that callback you can integrate your RS232 stuff. 

I suggest you take the com port opening and closing out of the timer controls, so that no time is wasted in unnecessary operations during the periodic callback.

If you want to see examples of timer control operations you can search for "Timer" in the example finder (Help >> Search Examples... menu function): you'll find several examples to look at to understand how to use timers.

Hi,

Let me tell you my application for  Image capture by Ximea Camera.

The background captured should be the moving average of the intensities  and change the value of the next background depending on the intensities of the following images .

Let me problem statement in the word doc named camera.docx.

I am unable to proceed for a moving array or shift register .

Could you please look my answer. and suggest a solution?

Thanks  a Lot

Hi, this question appears to be related to the LabVIEW environment, so please repost it to the proper board.

I think that all this wrong messages here are due to the habit of Labview programmers to think by images and signs, loosing the ability to read and understand textual information.
This board then should be have icons for reading impaired people. 
Just kidding, but not as much as someone can think.
