I think the solution is here

http://zone.ni.com/reference/en-XX/help/37..._appearance_db/

Select File»VI Properties, select Window Appearance from the Category pull-down menu, and click the Customize button to display this dialog box. By default, the settings take effect when the VI runs.

You're right. You can set it at design-time using that method, or you can set it during run-time using a property node.

They are half-cannibals. They like to eat lambs!

I'm beginning to think you've lumped us into that group.

I resemble that implication!

Have you looked at the examples in LabVIEW's example finder or searched NI's site?

Here's something to look at to start: http://zone.ni.com/devzone/cda/epd/p/id/4812

Seems like someone beat you to it.

In my factory job I've found that my managers expect me to be equal to an Electrical Engineer (I'm not), in my previous job I was expected to know everything about LabVIEW, SCC & a bunch of the other stuff already mentioned.

I'd add that you need to be able to research & learn new things on your own. Become proficient finding answers (including nuggets like prepending "site:forums.lavag.org" or "site:forums.ni.com" to a Google search).

The last thing I have to offer is that you should make sure that you understand what tasks they're going to throw at you and that they are very clear of your limitations. Getting a new job is exciting, but it stinks to be jammed into something you're unable to perform.

QUOTE (LV_FPGA_SE @ Feb 28 2009, 03:30 PM)

Can you let me know which HW and what LV version you are using?

I've got a PXI-7813R connected to a cRIO-9151 expansion chassis containing two NI-9403 DIO modules, and LabVIEW 8.6.

I'm developing an ATE that needs to communicate with a UUT that contains a microprocessor with a HOLD line. I can manipulate the UUT as long as I keep that pin high; the microprocessor takes over as soon as I drop it. These UUTs haven't had their programs loaded by this time (that's part of my ATE's job) so a watchdog takes over and the UUT isn't addressable until I cycle its power. (There are a few other lines/states that I need to maintain in order to conduct my tests.)

The problem I have is that I have to do a bunch tests and I use a few different FPGA programs to do them. I believe that the digital outputs are dropping when I push a new program to the target and I loose the control lines that allow me to work. I can regain control by resetting the outputs and cycling power every time I change FPGA programs, but I'd rather not (it just doesn't seem right.) My current solution is to take all of the individual programs and unpack them into one Uber-FPGA program (I'm compiling that now) but the block diagram is large and it hurts me when it doesn't fit on one screen.

Is there a way to keep the digital output lines from dropping when I change programs?

Thanks,

Jim

Is there anything preventing you from using a connection string instead of a datalink?

Ben offered to sponsor a coding challenge in this post in NI's forum.

Can you think of a good challenge?

I have to interview several people over the next week to fill a position one level above me. This person will be responsible for developing ATEs but will also have management responsibility for satisfying all ATE/test requirements in the plant. The resumes I've read so far don't have any LabVIEW experts and I'm worried! I'm not an EE and only have a few years under my belt doing Test Engineering, so I don't know what specific questions to ask.

I read the existing posts on interviewing to fill a LabVIEW developer position, but this isn't the same.

What can you suggest?

Thanks,

Jim

Yes, aleatory means random numbers between 1 to 10.

I need a matrix nxn, n rows and n columns (for example: 3x3, 4x4,5x5, 6x6, 7x7,....). The "n" must be entered by control.

Thank you.

Ok, you've confirmed what I thought. Have you tried nesting two For Loops and building your array? Put your Random Number stuff inside the inner loop, wire the "n" control to the "N" terminals and wire the random number through both loops to a 2D array indicator on the outside (with indexing enabled in both loops, of course).

Jim

QUOTE (vieira @ Feb 15 2009, 08:59 PM)

I need to do a square matrix with aleatory numbers between 1 and 10. The Array dimension must be entered by control and it has to be >= 3.

Once I figured out that "aleatory" means random, I got confused about what you're trying to do. The order of a matrix having m rows and n columns is m x n, so your square matrix cannot have an order of 3 (unless you 1.732 rows/columns). If I make the minimum = 4 I come up with the attached. Is this what you want?

Edit. Oops... this looks like homework (in my excitement, I only noticed it after I posted).

A hint: don't worry about the Initialize Array function; you know you need a two-dimensional array. The answer lies in nested http://zone.ni.com/devzone/cda/tut/p/id/7588' target="_blank">For Loops...

I don't have done nothig about voice recognition

I did some work with Visual Basic using Microsoft's Speech API; that would probably be a good place to start. You could make a dll and call it from LabVIEW. Here are a few links:

Microsoft Speech Homepage

Speech Input Technology - Architecture and Driver Support

Developing with Microsoft Speech Application SDK

Good luck! It would be neat to see what you come up with (post it here).

hey thanks for the reply. how about if i want the current output to be the next iteration input? and i have to do it for like 200iterations?

Study Shift Registers and auto-indexing tunnels. The "1" constant outside the loop initializes the Shift Register, otherwise you'd end up with an array full of zeros. The "200" causes the loop to run that many times. You can use a loop to auto-index an input tunnel, too. There's a lot to these structures, but it's all pretty basic and fundamental to programming.

Could you please teach me how to label the wires? I cannot find this function in LabVIEW; and I always do the system label only. Thanks

I get the system label from here: (someone else may get it from the Block Diagram, but I can't find it.) The System Label adapts to the background color. Your label wasn't like that.

[...] use Invoke Method of VI.Control Value.Set to programmatically set the values of controls in the called VI. If there is, for instance, a Pause control (with that name) in the called VI, then specifying that name to VI.Control Value.Set would allow the caller to Pause the called VI.

I don't think that this will work if the Pause control is handled in an Event Structure because setting the value of a control doesn't trigger an event. I discovered this yesterday and ended up putting a Value (Signaling) property node in the Timeout case.
