Error Compiling the second programm of the tutorial

[biozik]

Hello everybody,

I am a French student so excuse me for my bad English. I am currently working on the NXT Toolkit with Labview 8.2.1

I try to compile the sencond programm given in the tutorial which returns the value of the battery but I have these errors when I try to compile it.

ERROR: Indexing tunnels are not supported.

ERROR: An error occurred during parsing. Node was unable to be parsed. ((Class: CompoundArithmetic)  (VI: NXTToolkit.DC.FindNXT.vi))

ERROR: An error occurred during parsing. Node was unable to be parsed. ((Class: CompoundArithmetic)  (VI: NXTToolkit.DC.FindNXT.vi))

ERROR: Can't open SubVI. (destroyNXT.vi)

Do you know where is the problem? What can I do to solve it?

Thank you for your answers.

It seems to be a problem with NXT Direct Commands 😞

Is it possible to have some examples of progams made with the NXT Toolkit because I don't have found more tutorials?

Thank you.

I'm not sure I can identify the root cause of your problems, but I can make a couple of suggestions. I'm also not sure how much experience you have with LabVIEW, so let me know if you need more detailed info.

The indexing tunnels error probably means you tried to wire an array into a for loop or a while loop. Right-click on the terminal where the wire crosses the loop boundary and disable indexing.

Not sure about the parsing errors.

On the destroyNXT.vi error, try locating that file and opening it yourself.  Maybe the file didn't get installed correctly, or maybe trying to open it will give you more information about what the problem is.

Hello James B.

Thank you for your answer.

I have tried to see from where comes the "Indexing tunnel" error. It comes from the NXT.Toolkit.DC.FindNXT.vi . In fact, there is an array wired in a while loop but I don't have created it. It is a vi from the NXTToolkit.

About the parsing errors, there are in the same file NXT.Toolkit.DC.FindNXT.vi in the while loop.

In fact, the destroyNXT.vi is not installed. I don't have found it on my hard disk.

I have fond a similar problem in the forum here http://forums.ni.com/ni/board/message?board.id=beta18&message.id=260#M260

It looks like to be a problem with the mass compile. I have tried to re-install Labview and the NXTToolkit and I have always the same problem.

Thank you

So, did mass compiling the NXT toolkit directory help at all?

It looks like you're trying to compile a VI that uses direct commands to the NXT.

The direct command VIs run on the PC and so, you should use the regular LabVIEW run button (that is on the block diagram and front panel windows) rather than the run button on the NXT Terminal.

Does this help?

Thanks a lot John Field,

It was my problem. I made a mistake between these 2 buttons. I'm very stupid

Thansk James B. for your help too 😉
