Gyro sensor plot and save data on labview
Hi
I am an electrical and electronics engineering student in Hacettepe University.I wanted to ask you something about my project:
I have Labview 8.5 installed in my computer and lego NXT hardware.I am trying to have inputs from sensors acceleration,gyro,.. which are hitechnic(gyroscope) and nxt sensors(sound..).I am able to read sound sensor data using nxt and having a graph of it in labview.I am also able to take data with nxt (seeing valures on nxt screen).When i am trying to use the same labview vi procedure using waveform chart ,however i cant see the graph ,labview console tells me that gyro.vi is password protected.(i have downloaded the gyro VIs from hitechnic.com and copied them to addons file ).
Please can you tell me which procedure should i follow in order to read gyro sensor data and store it to be able to process the saved data with matlab.Please,if you have a sample VI for this process could you send it to me.
I am looking forward to having your answer as soon as possible.Thank you very much.
Thanks for answering me so soon.
I have a Lego mindstorms NXT and also I havealready bought a acceleration sensor and a gyro from HiTechnic.
I muss do a two wheel- self balancing, it something like you can see here:
http://mindstorms.lego.com/NXTLOG/ProjectDisplay.aspx?id=ee95fa2e-ab89-49bc-aaa8-dd8e422f9a3d
I want to programme it in LabView, and also I want to run the programme only on the computer and comunicate with the lego
via bluetooth.
The problem is that to run only on the computer I need to use Direct Commands, but I couldnt do it.
If you could help me or also if you could send me some VI (it doesnt matter if its with direct commands or not; just to have an idea) to read the gyro or the accelerometer, it would be welcome.
Thanks in advance.

I've attached a VI that I am using to acquire amplitude from Spectrum analyzerse. I tried to connect amplitude ouput to the VI Write Characters To File.vi and Write to Spreadsheet File.vi. Unfortunately when I run continual this VI without interruption, labview ask me many time to enter a new file name to save a new value.
So, How can I do to aquire and save date in the same time and in the same file when I run continual my VI for example during 10 min.
Thank you in advance.

HP8563E_Query_Amplitude.vi 37 KBHi,
Your VI does work perfectly. Unfortunately this not what I want to do. I've made error in my last comment. I am so sorry for this.
So I explain to you again what I want to do exactly. I want to acquire amplitude along road by my vehicle. I want to use wheel signal coming from vehicle to measure distance along road. Then I acquire 1 amplitude each 60 inches from spectrum analyzer.
I acquire from PC parallel port a coded wheel signal coming from vehicle (each period of the signal corresponds to 12 Inches). Figure attached shows the numeric signal coming from vehicle, and the corresponding values “120” and “88” that I can read from In Port vi.
So I want to acquire 1 time amplitude from spectrum analyser each 5
period of the signal that I am acquiring from parallel port.
So fist I have to find how can I count the number of period from reading the values “120” and “88” that I am acquiring from In Port (I don’t know the way to count a number of period from reading values “120” and “88”).
Here is a new algorithm.
1) i=0 (counter: number of period)
2) I read value from In Port
3) If I acquire a period
i= i+1 (another period)
4) If i is multiple of 5 (If I read 5 period)
acquire 1 time amplitude and write to the same
file this amplitude and the corresponding distance
Distance = 12*i). Remember each period of signal
Corresponds to 12 Inches).i has to take these
values: 5,10,15,20,25,35,40,45,50,55,60............
5) Back to 2 if not stop.
Thank you very much for helping me.

Waveform chart, plot and Dynamics Data and double data
Hello everyone !
I would like to get separate plots on the same waveform chart.
Actually, I am simulating 4 signals (but in reality, it would be signal from sensors) and I would like to get 4 plots.
In the end, I get 3 plots and no 4 plots.
It is very strange... Yet, I have selected 'Stack plots' and '4 plots shown'.
Actually, I can see the last data has been merged with the first one.
How can I fix that ?
Thank you !
Solved!

test5.vi 105 KBI'm not sure how you got into this state but try going into the chart properties (right click front panel chart and click Properties from menu) and under the appearance tab, unclick "stack plots", unclick "Show digital displays(s), hit "OK", then go into properties again and reselect those two boxes and hit okay. It should correct the problem.
All statements are my opinion and worth every cent you paid for them.

Record, calculate and save data periodically
Hi,
I am working on a labview project. I have a continuous input data which is updated every 100ms. I need to calculate the 15 minutes average value, one hour average value of this input data and save this average values into excel file continuously. I have problem about how to calculate the 15 minutes average input data value. I have look through some example for parallel while loop, but my main problem is how to calculate the 15 minutes average values periodically and save it to the file. Thanks for your help.
FredYou do not need parallel loops to calculate a running average. Just keep two arrays of old data in a shift register inside the same loop. The first array is 9000 points (15 min) and the second is 36000 points (1 hr).
Append new data to the top of the array and delete any excess points from the bottom. Calculate the average on the entire array every time you add a point and write these values to other Excel columns.

I have an excel template that I have created. I am opening that template, saving it under a different name, and then writing and saving data to that excel sheet at regular intervals. It is giving me an error 5, I understand what this means and I am trying to work around it. However after too many hours spent trying to figure it out, I have asked for any help or input. I have attached an example vi, not the actual one since it is very involved.
Thanks

Power Cycle Test 3.0 Excel Save Testing.vi 18 KBThis snippet encapsulates most of the previous suggestions, and adds a few of my own.
The first code shows one (simplified) way of building the output file name. It incorporates the Build Path function to combine Report File Path with the file name (don't need initial "\"), builds the File Name with Format into String, getting the Time part of the name from Format Date/Time String. I also use Build Path to get the Template path. Inside the For Loop, another Format into String gets the data that is placed in the 10 Excel cells. We don't write anything yet -- we're only filling in the cells in the WorkSheet (think of how you use Excel -- you could, but probably don't, save the WorkBook after every cell entry, you wait until you are all done and then do a Save, followed by closing Excel). Finally, when we are done, we save the file using the output name we want to use, then close Excel (which disposes of the Report Object). If we want to generate another report, with another (time-based) name, we can put this code into a sub-VI and simply call it again.
Don't worry if you don't have LabVIEW 2014 (which was used to save this snippet) -- most of the code comes from the original that you posted, so it should be a pretty simple edit to change that code to match this.

I would like to post fillable only forms to the public but not give them the option to save or email the filled in form. If they want a copy of what they've filled in, they must print it.
I believe I can do this by just creating a fillable PDF and posting it without adding any reader extension capabilities. I also believe there is no limitation, as there is for fill and save forms as per this other post I read: Adobe Acrobat X Pro * Enable Reader users to save form data.
My IT department is telling me they will not allow me to post fillable PDFs online due to a "license limitation" so I started researching this myself, and the above link is the only thing I've found. While that post specifically outlines the limitations on saving filled in forms, I'm really looking for something that specifically tells me that there is no limitation on fillable, non-saveable (yes, I know that's not a word...) forms.
If anyone can provide additional information for me, I'd appreciate it. Or, if I'm completely wrong in my belief and there's a limitation either way, feel free to set me straight. I'd rather know the correct answer than be right!
Thanks!!If you don't Reader-enable a document, then there are no licensing restrictions involved. Note that Reader 11 and all versions of Acrobat are able to save non-enabled forms, unlike previous versions.
The question should not be whether a form is savable, but rather whether you used Acrobat to add usage rights to the form AND you (the licensee) plan on receiving filled-in instances (including hardcopies) of it. The simplest way is to not Reader-enable the form and convince your users to use Reader 11 (or Acrobat) if they want to save. -
Using OBIEE Scheduler to export and save data in excel/pdf
Hi
Is it possible to use obiee scheduler and run particular reports and export the data into excel/pdf and save this file at given location on server.
env: obiee 11g/linux OS
Thanks for any ideas.Hi,
Yes it is possible.
As per my knowledge we don't have such option but we can do one way.
Using IBOTS you can store specific report and specific time in specific location.
Note : Using JS script.
Are you going to implement this way send me your mails id will send you js script for doing this.
Re: Auto SAVE to excel -- Please refer this thread.
Create js file using the below script and add this js scrif in your ibot advanced tab.
var FSO = new ActiveXObject("Scripting.FileSystemObject");
var foldername = 'D:\IBOT'
if (FSO.FolderExists(foldername))
var fileName = foldername + "\\" +Parameter(1);
var fooFile = FSO.CopyFile(Parameter(0), fileName, true);
else
FSO.CreateFolder(foldername);
var fileName = foldername + "D:\IBOT" + Parameter(1);
var fooFile = FSO.CopyFile(Parameter(0), fileName, true);
Thanks,

-BenOk, i have changed my classes a bit to try and fix the issue. I found a tutorial online called MJW avoider game or something and so i split some of my code in to seperate classes. But now the score doesnt update. I have fixed the loading issue (hopefully) i can access the main menu etc... but the highscore doesnt show at all after a game. Here are my classes.

Can I use wireless WIFI on a 9650 at home and save data usage
Hi,
I am ordering a 9650, and have a wireless network at home. I was going to go with the $15 data plan, because i use email mostly. Someone said I could use wifi on my wireless network at home for web pages to save data not going thru the verizon network? I am new to this, can you really do this?

Hi,
I think you made a great choice ordering the 9650 Bold. You can probably save a lot of money on the data plan by using the 15 dollar/month plan. You can do a lot with your BB with just the WiFi. I turned my WiFi on and turned off the mobile connection and was able to send/recieve emails, chat on Blackberry Messenger, and surf the internet. For me, using my home WiFi is a lot faster that using the mobile network. My only advice is to regularly check your My Verizon for your usage on data to make sure you are not going over the max usage for your plan. Good luck.

Steps to plan and save data in Workbook
Hi all,
Please provide me steps to Plan and save a data in a real time cube using workbook.
I have gone through different articles in SDN and tried to relicate but failed to save the data.
May be I am missing some thing, some steps. Please provide me with steps as giving links will not help me.
Thanks
SunnyHi,
You will have to follow the below steps to create a workbook which can save data in realtime cube.
1. First create Aggregation level(mandatory for input ready query which can save data) in Planning Modeler.
Aggregation level you will have to create on Reatime cube.
Transaction code for Planning modeler is RSPLAN.
2. After you have created aggregation level .
-> Create Query in Query Designer on the Aggregation level.
3. Make sure that you have made the setting for keyfigure as Input-ready.
Also make sure to make you have set the Query Property as 'Start Query in Change mode".
-> Then only query will be eligible for entering and saving the data on execution.
4. Now when you execute the query in Bex Analyser and save it as Workbook.
-> Data can only be entered and saved when the query open in input-ready mode.
5. The best way to check in Bex analyser whether query is input-ready or not is
-> In the query result layout , use Right lcik of Mouse -> then in the context menu
-> you should see the following two options apart from other options
Two options are:
1. Transfer plan values
2. Save values
If you get these two options then query is input ready and you can enter data and save it in realtime cube using the
Right mouse click -> Save values
6. If query is not coming as input-ready then it means that not all charateristics are drilled down
-> means that rows does not contains unique records.
In that case you will have to drilldown to make each rows contain unique records.
-> The best way is to restrict the characteristics with variable or single values in filter area.
-> this will give you drilldown data and so the query will come as input-ready.

The product documentation of the sensor and the datasheet is attached. Also Digilent MXP Breadboard's image is attached.
I've connected the sensor to myRIO using the starter kit's MXP breadboard: http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,842,1216&Prod=MXP-BB
The output of the sensor is in digital. My initial goal is to get digital output in form of 8 or 12 or 14 bits and then convert them to decimal numbers and record them.
Pin 1 of sensor is Data, which is connected to myRIO's connector A, DIO1 pin 13.
Pin 3 of sensor is Clock, which is connected to myRIO's connector B DIO5/SPI.CLK pin 21. According to the datasheet of the sensor, if VDD < 4.5V then Clock should be set to 1MHz.
Pin 4 of sensor is Ground, which is connected to Digilent MXP Breadboard GND pin.
Pin 8 of sensor is VDD, which is connected to Digilent MXP Breadboard +3.3V pin. Supply voltage range is 2.4-5.5V and recommended voltage is 3.3V.
I need to be able to send the following commands to the sensor from LabVIEW.
Measure temperature: 00000011
Measure relative humidity: 00000101
Then, myRIO has to wait for maximum 20 milliseconds (ms) for 8-bit measurement, 80 ms for 12-bit measurement, and 320 ms for 14-bit measurement.
Two bytes of measurement data will then be transmitted. myRIO as microcontroller must acknowledge each byte by pulling the DATA line (pin 13) low. All values are Most Significant Bit (MSB) first. Note that for 8-bit result, the first byte is not used. Finally, myRIO has to terminate the communication after the measurement data Least Significant Bit (LSB) has been received by keeping ACK bit, which is the LSB bit, as high.

Questions on Saving and mining data with Labview and DIAdem
Hi,
I am sampling two signals at 200k sampling rate. I am trying to save the data on harddisk and analyzing the data using DIAdem.
If I save the data using mesurement file format .tdm and .lvm, the file size will be about 4 Gigabytes for only 10 mins' acquisition. It is very slow to process it.
I used the software Clampex and pCLAMP(Axon Instruments) before. At the same 200k sampling rate and also acquiring two signals, these programs save the data as .atf format and the size is only 400 MB for 10 mins' acquisition.
I wonder if there is also a good way to handle this situation using Labview and DIAdem, and how to do it?Hi, Jonathan:
I tried the TDM binary file format. The file size is 800 MB per min acquisition and it will take a long time to just open these files. For my application, I have to take data for several hours. I am looking for a way to reduce the size of files.
Is there any other type of file format that can reduce the size significantly and can be handled easily? -
Is there a way to do a loop in VAB and save data to a file?
It is insisted that I form a loop counter in VAB, even though I have done it in LabVIEW. Is there a way of doing it in VAB? Also is there a way to save the data I collect in VAB or LabVIEW DSP module to a file on the computer? Any suggestions would be appreciated.
You can find one example in LabVIEW Help docments., in the "For Loop and While Loop Structures" .

Run program continuously and save data
Hi,
I am trying to get a program up and running that takes continuous measurements of an oscilloscope and then saves the data to a file.
I was able to find vi's from NI that work with my oscilloscope but am having issues getting it to take measurements continuously and am completely lost as to then save those measurements (I am just learning LabView).
Attached is my VI, and the readwaveform subvi it calls upon.
Any help would be appreciated, thanks!

Tk THS7xx Read Waveform.vi 107 KBIn order to take data continuously and write it to file you actually need to be running the VI continuously. You're not doing that since you have no loop. The "Run Continuously" button in the toolbar should not be used, if that's what you were doing. That's intended for specific debugging situations. You need a while loop and inside the while loop you call the VI to read the waveform. If you need to save the data at each iteration, then call the file write function appropriate for the way you want to save the data.
To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.
