Finite Measurements Project template

[unmnt]

Hello,
I am using the Finite Measurements Project template for acceleration
acquisition using an accelerometer. I made changes to the project and it is
working properly except for these three major points:
1)  Copy Graph- How do I put a ask user to define file path (A pop-up window)? It only
allows me to change the file path in the block diagram window.

2) Update UI -I would like to change to a free running VI and update the main
user interface during an acquisition real time. How do I do this? I tried
adding a data display loop. But it is not working properly.

3) Analyze- I would like to press the analyze button and be able to convert the
acceleration data to an FFT in the frequency domain. But it is not able to export the FFT data into the Main.VI

Thanks in advance for your help.

Unmnt,

If you are able to attach your project to your post it would help us out a lot.

1.  You can use the "File Dialog" Express VI and have the output of that VI go into the input of the invoke node.  This VI just pops up a browser similar to when you are saving a file so it might be better in the future to make your own SubVI so the user has a better idea what they are doing.

2.  This is where an attachment will come in handy but it looks to me like you are trying to use a queue to update a graph but I am not seeing where you are Enqueuing data.

3. I see you use the FFT functions but I am not sure what you are doing after you auto-index the outputs.  You might need to just add a FP indicator and wire that to the connector pane but again an attachment would probably clear this up.
