save data to array.vi 11 KB
Hi, K C. In another post I got some examples. In my case , I have a data source which outputs two numbers at a time(like 8.2 9.6), then after a fixed time interval, it outputs another two numbers...... I want to keep these numbers in a two demention array. I attach a example(add to array.JPG) from someone(in another post you can find the details) which has a fault , that is if two same number come along, it can only save one to the array. I attach another image of vi which I made myself(add to array[1].JPG), which has a fault too, I didn't know why, wish you can help me. Tomorrow I will go out for several days. So I cann't reply in the following days.

I'm not sure I get your point and only have LabVIEW 7.1, so could you just post an image of your diagram.
If what you want is to build (not save) an array, you should use the "build array" function in a loop, like this...

How to save data (DBL array) in a excel file
Ok, I am new into Labview. This question may seem easy for you guys, but for me, it is quite a challenge. I have current coming out of a loop. When the program stop, I would like to be able to save it as well as the time when it has been taking and the average current in a excel file. When my labview code stops, how do I do to get a pop up window which ask me where and what name to save it to? How do I get so that on the top of each column, it says : current (Amp) Time (ms) Average Current (amp)?
thank you very much,Hello,
We love to see people catch the LabVIEW spirit and anything we can do to help
you through the initial learning process is our pleasure.
As KC suggested saving the file as a .csv is a good idea,
you can also save it as a txt file and open it with Excel specifying a delimiter
for the columns.
There is a really good example you can find in the LabVIEW
example finder if you search for the keyword ‘file’, the example is called “Write
to Text File.vi”. They use a Get date/time String to record the time when data
is acquired.
I have attached a simple Write to File picture of a VI that
takes a random number and writes it to a file. When I run the VI, a popup asks
me what I want to call the file. The first part writes the heathers on the
columns and inside of the for loop I save the data. Underneath the block diagram
is a picture of the output file when I specify the number of samples to be five.
If you want your file to be on a very specific format, you
can create a template file, read it in LabVIEW, and then add your data to it
and save it to a new file.
Hope this can get you started with your program.
There are a lot of good tutorials online on how to
get started using LabVIEW. Here is the link to a three hour
introduction course:
http://zone.ni.com/devzone/learningcenter.nsf/03f7c60f17aad210862567a90054a26c/60c2782788a811c986256cd50001a0a6?OpenDocument&node=200067_us
We are also comming out with LabVIEW 8 in November and we have a program called LabVIEW Standard Service Program
(SSP) that allows you to get automatic upgrades and updates. Please let
me know if you are interested in knowing more about it.

How to save a 4D Array in a File and load it later on?
Hello,
I am trying to save a 4D Array (Array[4000] [3] [20] [5]) of UINT in a File. I can do it through "write in binary File". But then I can´t load it. I know I can transform my Array down to 1D Array of 1.200.000 Elements (4000*3*20*5) of UINT. When I load it, I have to transform it back (with a lot of "for-looping") back to 4D. But is there an easier way of doing that?
I was not able to find a solution in this forum - I am sorry if I made a new thread if there is already a solution in this forum.
Best regards
LabVIEW 2011
Solved!
Go to Solution.As Lynn said, there should be no extra code required.
When writing, make sure that "prepend size" is true (true is default) and when reading, wire an empty 4D array of the correct representation to the "data type" input.
(I also assume that your LabVIEW version is not extremely ancient)

How to save data in 4-bit mode instead of U8
Hi
I use LabVIEW to acquire and save data through the counter timer PCI6602.
My signals are really low so the data can be expressed in 4-bits (0-15).
I have used the conversion to U8 and write them using "Write Binary Files"
So this uses 1 byte for each data point but I would like to reduce it to 4bit (half byte) for each data point.
Can anyone help me with this?
I am attaching my program for reference

DAQ-longvector1.vi 64 KBHere's some easy code how to do it.
Note that this code assumes that the data is 4bit (0..15). If any of the upper 4 bit are set, you've got problems, of course
See if this makes sense. Good luck.
This example uses a single 1D array. You would eliminate the decimate/interleave and just use the two arrays.
A small comment to your code. There are a few weird constructs, but the use of two "split array" operations to take a simple derivative seems overkill. This made a honorary mention in the Rube Goldberg Hall of Fame.

How can i save the output array of the invoke node "commands values" into a specific file
I must save the setup of vi commands'. I use an invoke node called "command value" wich give me an array with the name of the specific command and his value. How can i save this array into a specific file to load it later if o need. Must i change the array format?
Thank youHi,
I have attached two VIs.
The first one "Ecriture fichier tableau" (writer) permits to collect all control's values in an array (dbl) and to save it as .bin file. You had to convert variant type into dbl type. (You can do the same with string type if you wish. You will save datas as .txt file for example)
The second VI "Lecture tableau fichier" (reader) permits to retrieve all the datas you saved in the file.
I think this responds to your question.

Can I save data (in txt or excel format) from a snapshot from signal express 2013 LE? My data buffer is too larege to export to excel. When I try to take a snapshot, I do not see any data. Are snapshots supported in the LE mode? This is the free version that comes with the USB 6009 ADC.
Yes, the snapshot function is available for SignalExpress 2013 LE. Does the snapshot function as intended when you try other projects?
