Need help modifying code. (Non-programmer)

[Saara]

I use LabView to collect friction data in a wear test. I recently purchased new instruments and LabView 8.6.

The code attached was programmed by a friend. am unable to use it because:

1. instead of giving 1000 samples and 1 channel, the logged data shows 1000 channels and 1 sample data

2. the final values are frictional force values. i need Coefficient of friction

3. i need to add channels (quarter and half-bridge configuration - strain gauges) but have no idea how

I do not know how to program, Labview or otherwise.

Please help DAQAsst.vi

Since you don't want to learn LabVIEW I would stay with Signal Express. for your acquisition.

If you want to stay in LabVIEW (and don't want to learn) I would never do what you did, take an Express VI and convert it to editable code. Just try to reconfigure the Express VI.

Hello Ton,

How do i reconfigure the express VI? Need the program in a few weeks. not enough time to learn.

Saara:

I think you need these steps to complete it.

1. right click express VI

2. select "open front panel"

3.push the dialog "Convert"

4.now , you could read the source code and configure any item that you want

I actually think Ton meant not to convert the Express VI, but instead you should configure the express VI by right click, select Properties.

This will take you to the DAQ assistant, where you can add/remove channels as you want.

I have not checked your code, but if it is already converted to DAQmx code, you will have to restart by adding the DAQ Assistant Express VI from the Express->Input palette.

Then configure the channels as needed.

A "few weeks" ought to be enough time to learn how to configure an Express VI. No?

Since you're not a programmer, I'm not sure how helpful suggestions on re-implementing your code will help. The code that your friend gave you does not apply to your question, so do not use it. Watch this and this. You can find more info here.
