Text file - Labview - Blinking LED (eg daq)

Hello all,
I am totally new to labview. I'm supposed
to read data from a Text File, then use the file in labview to generate
an output when certain conditions are met. The output is in the form of
a daq card (emant) which has LEDs and i'm supposed to make it light up.
Help me.

Hi Krum,
Thanks for the post!
I would recommend looking at the example finder, Help>>Find Examples. There are examples on reading from text file AND software triggered DAQmx tasks with pre-loaded waveforms (i.e. data from text file). I would try and produce some code, and then post it if/when you get stuck.
Otherwise, maybe try asking some more specific questions.
Kind Regards,
Kind Regards

How to create and read text file using LabVIEW 7.1 PDA module?

How to create and read text file using LabVIEW 7.1 PDA module? I can not create a text file and read it.

File_IO.vi ‏82 KB

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

Want to convert the .DAQ file from MAX to a text file to be included with data runs for experiments.

I want to take the .DAQ file from the MAX program and convert it to a text file. From my understanding this file contains all the information for the channels and hardware that is currently set up on the system. I want to use this data as a file so that others can set up the experiment again in the future and this data would be helpful. Thanks in advance for any help in regard to this matter.

HAL;
I'm attaching a Labview example to this answer which does that with the properties of your virtual channels configuration in MAX. Other than that, there isn't any way, at this time, to convert the .daq file to a text file.
Hope this helps.

Transfer time stamp from text file into MS Access thru Labview

Hello everyone,
I am Cruz; Long time listener, First time caller.
I am currently monotoring data being collected by an oven. The data is stored in a text file. I am using Labview to take the data from the textfile and place it in an MS access DB for manipulation. The first three columns of the text file are the time stamp of data. When i transfer the data into Access i cant get the first three columns to display as a time stamp. Can have some pointers on what how to get the first three columns to display correctly.
Additional info:
the text file is a 1D array that gets overitten with every new mesurement tanken. the transfer to Acces is to not loos any of the information and to better manipulate the data into forms and such.
Running Labview 2010
attached is code and text file.
Any help is greatly appreciated.

Your first mistake is reading the file as DBL. Your first three columns are obviously not numeric values. Did you ever look at the output array? Read it as strings. Second, you would need to combine those first three columns to create an actual time stamp before you write to the db. Unless of course you have one column for date, one column for time, and one column for AM/PM. I would not recomend that type of structure in the db.

LabVIEW for ARM 2009 Read from text file bug

Hello,
If you use the read from text file vi for reading text files from a sdcard there is a bug when you select the option "read lines"
you cannot select how many lines you want to read, it always reads the whole file, which cause a memory fault if you read big files!
I fixed this in the code (but the software doesn't recognize a EOF anymore..) in CCGByteStreamFileSupport.c
at row 709 the memory is allocated but it tries to allocate to much (since u only want to read lines).
looking at the codes it looks like it supposed to allocated 256 for a string:
Boolean bReadEntireLine = (linemode && (cnt == 0));
if(bReadEntireLine && !cnt) {
  cnt = BUFINCR;    //BUFINCR=256
but cnt is never false since if you select read lines this is the size of the file!
the variable linemode is also the size of the file.. STRANGE!
my solution:
Boolean bReadEntireLine = (linemode && (cnt > 0)); // ==
if(bReadEntireLine) {    //if(bReadEntireLine && !cnt) {
  cnt = BUFINCR;
and now the read line option does work, and reads one line until he sees CR or LF or if the count of 256 is done.
maybe the code is good but the data link of the vi's to the variables may be not, (cnt and linemode are the size of the file!)
count should be the number of lines, like chars in char mode.
linemode should be 0 or 1.
Hope someone can fix this in the new version!
greets,
Wouter

"LabVIEW for ARM guru and bug destroyer"

I have another solution, the EOF works with this one.
the cnt is the bytes that are not read yet, so the first time it tries to read (and allocate 4 MB).
you only want to say that if it's in line mode and cnt > 256 (BUFINCR) cnt = BUFINCR
the next time cnt is the value of the bytes that are not read yet, so the old value minus the line (until CR LF) or if cnt (256) is reached.
with this solution the program does not try to allocate the whole file but for the max of 256.
in CCGByteStreamFileSupprt.c row 705
if(linemode && (cnt>BUFINCR)){
cnt = BUFINCR;
don't use the count input when using the vi in line mode. count does not make sense, cnt will be the total file size. also the output will be an array.
linemode seems to be the value of the file size but I checked this and it is just 0 or 1, so this is good
update: damn it doesn't work!

Charting data from text file in LabVIEW 5.1 for Windows

I am having some difficulties trying to figure out how to plot a chart with
data from a file. I would like to be able to read data from a text file
into a chart using LabVIEW 5.1 for Windows. I have looked in the help
within the program and online. I have also looked in the user manual and
the book "LabVIEW for Everyone". Could you please give me specific
instructions on how I would construct the program to be able to do this.
Thank you.

Hi Ellie,
It depends on how data is stored in that txt file. Usually you load the data into an array either using or , the array if necessary and send it to the graph indicator in required form. If you want a more detailed answer, send me a sample data file ([email protected]).

Print text file with labview 2011 and windows 7

I am having some strange problem, hope someone out there knows the solution.
We have a labview program running under windows xp, the program runs some test and print label from a local label printer. Last week, I have to upgrade the computer to windows 7 and all the sudden the printer will not print any more.
The print vi is very simple. I am using the report function and I am attaching the diagram of that vi below.
If I use windows notepad to open that small text file, I can print fine. This means the printer driver itself is OK. However, if I print the same text file through Labview printing vi, from the printer's task list, I can see it does not recognize the char. From the attached png file, the top one is the task from notepad, it shows 2 pages and the bottom one is from the labview, it becomes 33 pages.
For the printer part, I use Generic / Text Only printer driver which comes from windows itself. And I am aslo attaching a sample of the text file, there are quite a lot of special char, it is for print bar code. When I tried to use labview print text vi to print general text from my computer to a regular printer, the vi works. So it seems Labview print can not handle the special char? Although it worked many years under windows XP in the past.
Welcome to any suggestions!
Thanks

where to check RAW or TEXT? the print report vi only asks for file name and printer name.
When I print from notepad, everything just goes by default. This is a label printer, so I never need to specify printing parameter such as size, orientation, etc in the past
Famous last words go something like this: "...never had to do that before." Maybe you have to do that now. It's worth at least comparing the defaults settings for bothe generic drivers. It could save you a lot of headache if you notice something different.

I would like to read a text file in which the decimal numbers are using dots instead of commas. Is there a way of converting this in labVIEW, or how can I get the program to enterpret the figures in the correct way?

The program doest enterpret my figures from the text file in the correct way since the numbers contain dots instead of commas. Is there a way to fix this in labVIEW, or do I have to change the files before reading them in the program? Thanks beforehend!

You must go in the labview option menu, you can select 'use the local
separator' in the front side submenu (LV6i).
If you use the "From Exponential/Fract/Eng" vi, you are able to select this
opton (with a boolean) without changing the labview parameters.

Plotting data from a text file in LabView 7.1

This my be a stupid question, but here is goes. Working with another person, far more LabView experience than I, a VI was created to take data and output it on the screen, real time, as an x-y plot. Once the test was completed the data was stored in an .txt file which could be read into Excel. Now the end user wishes to read the old data back into Labview with an x-y plot of the data, the same way it was displayed during the test. Before I started to pound my head against the wall, thought I would ask this to the group. Everyone has been very helpful in the pass, so hopefully this will be an easy question for the group.
The question is how do I import a text file into Labview and plot it on an x-y screen?
Thanks,
Scamper

It really depends on how you've saved the data. If you have a simple text file with x data in one column and y data in another, then you can use the code below. It's just a Read From Spreadsheet File, and Index Array, and Bundle function. Modify as needed for your actual data. If you get stuck, post a small example of your data file.

Deleting a column in a text file using LabVIEW

Hello all,
I'm trying to delete the first column of my tab delimited text file using LabVIEW and then save it under the same file name. Can someone show me a quick way to perform this operation. Is this even possible with LabVIEW? Any help would be much appreciated.
My purpose is to automate this operation for hundreds of daily text files containing data that needs processing. I'm currently using LabVIEW 8.2.
Thanks!
-noviceLabVIEWuser

If the file is relatively small:
Read the file using the Read from Spreadsheet File VI to get 2D array.
Remove the column from the 2D array.
Write out new 2D array to new file using Write to Spreadsheet File VI.
If the file is relatively large then you will likely run into memory issues. In this case you will need to read the file in chunks. You can decide how many lines to read at a time. Use a for-loop that's set to run for the number of chunks to read (based on the total number of lines and the number of lines you want to read at a time). Hint: Quotient & Remainder function. In the loop use the Read Text File VI to read your set number of lines. Convert the lines to a 2D array delete your column, and write out that chunk of data to the new file. Rinse and repeat.

Exit labview (executables) after using large text files

Hello,
I am using LabView 6.0 and his aplication builder / runtime engine. I wrote some VI`s to convert large Tab delimited textfiles (up to 50 mb). When I am finished with the file it is staying in the memory somehow and is staggered with other (text)files in such a way the computer is slowing down.
When I want to exit the VI (program) it will take a very long time to get lost of the program (resetting LabView) and get my speed back.
How kan I solve this problem for these large files?
Martin.

OK, this may be a bit of a problem to track down, but let's start.
First, while your front panel looks great, your code is very hard to read. Overlapping elements, multiple nested structures and a liberal use of locals make this a problem. My first suggestion would be to with a massive cleanup operation. Make more room, make wires straight, make sure things are going left-to-right, make subVIs, place some documentation and so on. You won't believe the difference this makes.
After you did that, we can turn to find the problems. Some likely suspects are the local variables and the array functions. You use many local variables and perform resizing operations which are certain to generate copies. If you do this on arrays with dozens of MBs of data, this looks like the most likely source of the problem. Some suggestions to deal with this - if you have repeating code, make subVIs or move the code outside of the structures, so that it only has to be run once. Also, you seem to have some redundant code. For instance, you open the file only to see if you get an error. You should be able to do this with the VIs in the advanced palette without opening it (and you won't need to close it, either). Another example - you check the exit conditions in many places in your code. If your loop runs fast enough, there is no need for it. Some more suggestions - use shift registers instead of locals and avoid setting the same properties over and over again in the loop.
After you do these, it will probably be much easier to find the problem.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).
And one last thing - having the VI run automatically and then use the Quit VI at the end is not very nice. Since you are building it, it will run automatically on its own and you can use the Application>>Kind property to quit only if it's an executable.

Reading from graph to text file in labview 7.0

Hi Guys!
I am doing a project which reads analog values from a microprocessor board and I am using the Labview example Cont Acq&Graph Voltage-Int Clk.vi. I am getting an analogue graph using this VI. is there any way I can convert the values on the graph and save them to a text file?
Any help would be much appreciated!
Thanks
Pauline

Hi Pauline
There are two ways. Either you place the Export vi in the vi you're already using or you assign the waveform indicator to a terminal (search the LV help for terminal). This makes the waveform-data available for other vi's if you use the Cont...vi as a sub-vi. This means you can create a new vi, place the cont acq&graph valtage-int clk.vi and the export waveform to spreadsheet file.vi in it and wire these together (similar to all the vi's in con acq&graph...vi).

There are so many things wrong with this VI, I'm not even sure where to start.
Hard-coding paths that point to your user folder on the block diagram. What if somebody else tries to run it? They'll get an error. What if somebody tries to run this on Windows 7? They'll get an error. What if somebody tries to run this on a Mac or Linux? They'll get an error.
Not using Read From Spreadsheet File.
Use of local variables to populate an array.
Cannot insert values into an empty array.
What if there's a line missing from the text file? Now your data will not line up. Your case structure does handle this.
Also, how does this answer the poster's question?

Text file vs labview

Hi. I have a text file of data ( please, look at the attachment) and i want to create a single photoelectron's time spectra. I'm studying the transit time: i want to understand and characterize photomultiplier tube response to various signals. My teacher sent me that text file. I have create charge spectra by matlab ( charge spectra at 1651 V, 1710 V and 1580 V). But I can't use labview to create this time spectra ( i can't use functions tools and other ones). I need to convert 1-8192 channels in time, so i could create Transit Time Histogram. So, could you help me to convert x - axis ( in attachment is the channels number 1-8192) in time? I need create a data chart ( with data in my text file) in labview...thanks anyway.

Today seems like an Example Finder day for me and my suggested solutions.
LabVIEW can quite readily perform the tasks you need. If you open the Example Finder, available in the pull-down menu under Help >> Find Examples... then and search for "read text file", "Histogram", and "graph" you will find general examples to do what you seek.
