collecting and clearing elemnets after dimension reaches to [x values] in an array

Hi all,

 

I need some help, here what I am trying to do is to take 3 channels from acquisition device (BIOSEMI) and collecting 8 elements each time in 3 different array until it reach to 256 elements. Once these arrays are filled with 256 elements, then transfer it for further processing but at the same time reset these 3 arrays to again collect another 256 points in 3 arrays.

 

How can reinitialize my arrays after every 256 points but at the same time keep forwading these 256 points for plotting and further porcessing?

 

Many Thanks.

 

Amna

Hi Amna,

 

- please clean up your VI before uploading…

- replace InsertIntoArray by BuildArray when appropriate…

 

What kind of help do you expect when all you provide is a picture of a block diagram? Should we use GIMP to paint into that picture?

 

To answer your question:

IF array.length >= 256 THEN
   array := []
ENDIF

 Sounds like you need a simple Case structure (or a Select node).

Best regards,
GerdW

Hi GerdW, thanks for you reply. I was trying to upload the vi but it needs other file to open (.dll) which is unsupportive format.  

 

Thanks for solution, I'm trying to apply it and will update soon.

That sounds like you need a FOR loop to me.  Just make it iterate 256 times, autoindexing your read values.  When the loop is done, pass on the data.  Next time you come to the FOR loop, the array will be reinitialized.
