kind of buffer problem

[fred]

Hi out there!

Me again..

I have a programmately problem. I attached an analogous program to my real.

A special hardware sends data in portions with no sending data between the portions.
I want to collect the portions into one array in an parallell loop.

See file for more information.

Thanks Fredda

The wait function in loop 2 should be 50 ms!
I forgot to change.

Hi Fred
You can use a queue:
loop 1: enque elements 1 by 1
loop 2: dequeue 1 elements

Take a look at theese links:

if your problem is the fact that your file "all.txt" is blank
try with this solution :))

You probably should carefully rethink your overall program design, but here is a quick and dirty solution to give you some ideas:

Remove the timing in the second loop, but place an event structure triggered by the number. In loop one, write to a signaling property of that number to trigger the event whenever new data occurs.

See attached (LabVIEW 7.0).

Hi Fred
Well, perhaps I didn´t understand your problem.
I think the solution could be "queues". ( don´t care about file writing)

Hi!
thanks for your tip!

The only problem is that the arrays from both loops in filewrite(open the writefiles)
differ a little. The second loops array doesnt exactly follow the array values from loop one!

Why?

Take a look at my attached file

HI!

Could you please describe in detail how you
used the property node for my program, dont get
how you made it work. Have not used it before.
