I am just taking my first steps with Labview. I have created a couple of VIs and have managed to get I2C communication happening through a third party DAQ box. The problem I am having is fairly simple, I am trying to save VIs but they are not retaining the values I have entered in the Front Panel.
I have a top level VI and a couple of subVIs that contain lower level functionality for sending I2C messages. The top level VI has a couple of value controls that let me enter device addresses, etc. It also has groups of toggle switches that I am using to set bits that I later combine into bytes of data that I can send.
But whenever I save a VI the front panel settings are defaulting to some other value. I dont understand it, I just want the value box to hold the number I entered. And more importantly in this case I need the array of toggle switches to stay where I set them so when I run it again the same bytes are transmitted. But each time I open the VI, the toggle switches are all greyed out and set to 0.
Is this normal? How do I get controls to retain there values? Is there a design reason they do not?
Thanks for any advice.
