Monty Python has made an official YouTube channel.  They had this to say:

WooHoo for Monty Python.

Will NI's 8451 do the job for you?

I thought of that as I was driving home. It'll work fine, but they cost 2X the Aardvark.

That brings me to another point in this sad story. I need a new one because my existing station went down this morning when a bad UUT put 28V to the clock and/or data lines. I had a spare! ...which, they promptly destroyed this afternoon. Any idea how I can protect these lines?

Hi,

I need a USB I2C adapter (with LabVIEW drivers) that I can use to replace an existing part. I've been using TotalPhase's I2C Host Adapter but can't get one fast enough. It's a long story...

Can you recommend one?

Thanks,

Jim

To use a formula, can I say that I had to specify an input into the formula, and let the formula operate from there?

You don't need to specify an input to a formula, but it's essentially a constant if there are no dependent variables.

We should seriously make a page for this on the http://wiki.lavag.org/' rel='nofollow' target="_blank">LabVIEW Wiki and link HH to it when necessary. can someone please do the needful?

I'll give it a shot.

From here.

If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm.

Please post your instructor's email address in case I have any questions about your assignment. In fact, I have a great idea. I could just email your assignment directly to your instructor and then you wouldn't even have to go to class either!

My question is how can I read data from the instrument? I tried to Initialize -> Read -> Close but it reads wrong values for example for DC volt it reads 513,123V.

I think you're missing a step; the example has Initialize -> Configure -> Read -> Close.

One quick comment, the "Standard State Machine.vi" has a three deep case structure in the "Update" case. Use the "select" function in the comparison palellete for a cleaner and more readable vi.

I was going to say that! I always get beaten to the punch...

Also, and I don't know if it matters to the judges, but it's cleaner to label your wires with a System label.

Good job!

this is something which i had tried, however i don't see any output waveforms.

did i miss out on something?

• You didn't wire anything into the graph
  
• Your formula only makes one data point; I think you need a chart instead
  
• Your formula calculates to a constant
  

Try this one

NI says that a CLD:

QUOTE

• Demonstrates experience in developing, debugging, and deploying medium to large LabVIEW applications
  
• Possesses experience of 12 to 18 months developing medium to large applications in LabVIEW
  

Passing the CLD exam doesn't prove that you fit this description, but it sure does make people think that. It's a bit of misrepresentation to present yourself as a CLD without having the ability to back it up.

I passed the CLD exam with less than one year of experience. When I left my first LabVIEW position, my new employer knew only that I was a CLD (and that I interview well enough) and hired me. The pressure to produce at the level they expect is high; I've worked a lot of hours and still look back and shake my head at some of the programs I've written! I expect to always keep learning, but at some point my basic approach has improved and my code is cleaner. I think that this is what is expected of a CLD.

I've toyed with the idea of sitting for the CLA exam. I doubt that I'd pass it the first time, but I'd sure learn the test. I'm good at passing tests and would probably pass the second time, but then I'd be misrepresenting myself. A CLA:

QUOTE

• Demonstrates mastery in architecting LabVIEW applications for a multi-developer environment
  
  
• Demonstrates technical expertise and software development experience to architect LabVIEW components
  
  
• Manages projects by effectively utilizing project and configuration management tools
  
  
• Possesses experience of approximately 24 months in developing medium to large LabVIEW applications
  
  

Good luck with your career, but know that a LabVIEW job interview might contain a test! This has been discussed on this forum here, and other places.

EDIT - Oh, yeah. I've begun working with the OpenG project in an effort to learn more of the "architect" and team-oriented development stuff that is expected of a CLA. I expect this will be a mutually beneficial relationship in that I'll grow as a developer and, in exchange, I'll work on Open Source software that many of us use. Talk about a win-win situation! I've also thought of working on something for the Code Repository (may still do that). These are options for you, too, to help you gain the experience you need to go along with certification you want.

I've managed this.

Silly me, I didn't wire the error cluster into the Shift Register.

This deletes files but doesn't send them to the Recycle Bin. Any ideas of how to get them there? I'm thinking .NET, but I've never dot-netted anything.

Here's your code, slightly modified. You were so close!

• I added a delay (to stop hogging the CPU)
  
• I added a Case Structure and a Shift Register (to control when the 30 second timer operates)
  
• I deleted your wire between Get Start Time and Set Start Time
  
• I changed the Boolean control to a constant to Auto Reset the first timer
  
• I added a First Call to the test so you'd get your measurement at T=0
  

You'll also need to multiply your "at every" control by 3600 to get the first timer to run for hours instead of seconds.

But Why the VI in the pic is OK? What is the meaning of communicating between while loop(case structure)

The pictured VI is fine because the two loops aren't trying to run in parallel. The first loop is building an array of random numbers and the second loop simply indexes through that array, increments each element and displays it on the Front Panel (although, it'll be too fast to see). This wouldn't work if you wanted to display the incremented value in the second loop while the first loop was still running. (BTW, you'd be better off using a For Loop instead of the second While Loop; it'll auto-index the array and you don't need to worry about the loop conditional terminal.)

I have to ask, what do you think the definition of data flow is?

This looks like a follow-up to http://forums.lavag.org/-t12864.html&view=findpost&p=56729' target="_blank">this post. zmarcoz, you were asked to post a picture of what you were asking. That'll get you your answer.

It looks to me like you mistakenly wrote "case structures" instead of "while loops" here.

QUOTE

I recall a question that had a wire from the stop button in one while loop going to the conditional terminal in a second while loop. The problem with this architecture is that the second loop won't start until the first loop is stopped (with the button), then it will only loop one time because the stop button sent a True.

Of course, I'm only guessing BECAUSE YOU DIDN'T POST YOUR CODE/PICTURE. You're running out of time! Good luck tomorrow. :thumbup:
