data logging to file or xls

[RvG]

I am logging data every 0.5 second to a txt file. When I need to store more values than I have in this VI the structure will be very unclear. Is there a better way for data logging?

Yes.  The "array to spreadsheet string" function is your friend.  It's on the "strings" palette.

You have a lot of unnecessary manipulations in your code.  You don't need to go from a 1D array (which you unnecessarily resized to a 1D array...why??) to a cluster, which you then unbundle, in order to obtain your data.  You can just use the array functions.

Also, that case structure you have -- the one containing the "select" functions -- is just silly.

This

Is exactly the same as this

There were a few other things in there too that didn't make any sense.  I've tidied up your code somewhat, eliminated most of your unnecessary operations, etc.  Have a look.

Hope this helps,
