Iam developing an application using NI-DAQ(AT-MIO-16E)card on vc++ environment.My requirement to extract amplitude of AM signal(1khz(4step waveform) on 70Mhz carrier).Mr Ben suggested about sampling.
My application is having a device that takes 1khz and 500Hz clock and 70Mhz carrier.And generates AM signal(1khz(4stepwaveform)on70Mhz).
each step of 250 micro sec.
Iam using couter0 and 1 outputs of NI-DAQ card for generating clock.
I need to generate a clock through card and syncronously i should acquire the 4 step levels
of incoming AM signal(1khz(4 step) on 70Mhz)in each cycle.And i should generate error voltage like e1=(step1-step3) volts
e2=(step2-step4) volts
for each cycle i need to generate e1&e2
I am planning to use
DAC0 and DAC1 pins on ni-daq card for sending errorvoltages.
For implementation of whole thing.what
ni-daq functions should i use.
I am planning to use DAQ_Rate and DAQ_Start functions for sampling the incoming signal.
counter functions for generating clock.
Mr Ben suggested about sampling AM signal.
that is about 40khz.10 samples for each step.
I need some help regarding how to interface the incoming signal(AM signal) with the card.
could it possible to connect signal directly to ni-daq card one of the analog input channels?.
regarding sycronization of clock and sampling of
incoming signal please help me.
thank you for ur help
Your two best resources for developing any Data Acquisition application are the manuals for your board and the examples shipped with NI-DAQ. Your board's manual should have information regarding wiring. That is, it has a section dedicated to how to connect signals to your board.
The examples shipped with NI-DAQ show several Input/Output methods. These should give you a general idea (if not a specific application to your project) of how a Data Acquisition system would look (AI config, start, read, close, etc). These examples can be found in the \examples directory.

PWM signal from Accelerometer by using DIO of PIC-MIO-16E-4
I am a new beginner to use digital signal acqusition. The accelrometer send the pulse width modualated signal and I need to use DIO line instead of counter. I wonder how I can measure the pulse width, + duty, and -duty.
Hi Gino,
If you plan to use the digital inputs of the PCI-MIO-16E-4 then you will be limited to software timing since the digital inputs are asynchronous and dependent on software calls. This means your fastest rates are roughly 100-1000Hz (computer dependent). Since you also want to sample a period at least 5 to 10 times so that you can get a somewhat accurate representation of the duty cycle and the pulse width, you are further limited to the signal being slower than 10-200Hz.
However, if this is acceptable then you only need to create a loop and sample your digital inputs at the desired loop speed and perform calculations to determine the duty cycle.
How you would determine the pulse width and duty cycle is everytime you take a digital measureme
nt you also use "Count Ticks (ms).vi" in LabView to count the time between each call to this VI. You simply add these times while the reading is high and you have the high dutycycle. Do the same for low and then add the two together.
Hope that helps.

Need your suggestions for developing a Forum Site using Adobe Flex
Hi ,
I want to develop a small Forum Site where people can post questions and reply to questions .
I want to develop the whole thing using Adobe Flex , Is there any plugin avialable for this .
Means i mean to ask , if i go for normal J2EE there is a JForum avialable as far as i know .
Please share your ideas .I meant "Don't use flex" unless you have some superb new design for a forum. I suspect that if you already had such a design, you wouldn't need to ask the question. Flex for Flex sake isn't good.
There are already great html forum solutions out there.
Basically, there's no point in duplicating in Flex what is already done in HTML, unless the Flex version offers a significant improvement to the user experience in some way.
I am not aware of any Flex forum implementations and there is probably a good reason for that.
Maybe someone else will know of one. -

We have developed a desktop application using Flash software and published the same for MAC environment. When we double click on the index.app file, the application is working perfectly in Mac 10.6.7 at our office. But if the same index.app file is double clicked in Mac 10.6.7 at out clients location, its not opening. For your information the client is able to open this same application by double clicking on index.swf file. The main problem is that client is not able to open the application using index.app file at their office whereas we are able to do so at our office. Can anyone give some suggestions to sort this problem?
The most common reason is different versions of Flash, or different versions of web browsers used. Some users may elect to not have Flash installed at all because of the processor overhead of Flash. If you are going to make an application for a client, check what operating system and browser versions they are using first. Then determine if a stand alone application is required, or if they have the necessary plugins to run specific browser enhanced code.
P.S. MAC is an acronym for Media Access Control. Mac is the shorthand for Macintosh, the operating system and computers made by Apple Inc. -
[b]Tutorial:[/b] Simplify Developing OLE Automation Code Using VBA
INTRODUCTION
Automating Office applications from Oracle Forms can be a tedious, frustrating, and time-consuming process. Because the OLE2 and CLIENT_OLE2 built-ins do not validate the automation commands that they relay, code that compiles without errors often dies at runtime with a not-so-helpful error code. This tutorial will demonstrate how to simplify the development of automation code using a tool that ships with all Microsoft Office editions -- the Visual Basic for Applications (VBA) IDE.
The VBA IDE, a core Office component, is a full-fledged development environment featuring code completion, basic syntax highlighting, context-driven help and a runtime debugger. Its Object Browser provides a convenient means of browsing the Word object model, as well as searching by keyword.
For those who may not interested in following this tutorial in detail, I would like to stress the usefulness of the Object Browser as a tool for inspecting the functions supported by OLE server applications and, perhaps more importantly, valid values for function arguments. Whether/not anyone buys the assertion that starting with VBA prototypes is far more productive than pounding out OLE2 code from the very start, they will find the Object Browser invaluable as a reference -- I rely on it exclusively for this sort of documentation.
A BRIEF INTRODUCTION TO THE VBA IDE & THE OBJECT BROWSER UTILITY
Try this:
1. Open Word
2. Launch the VBA IDE by pressing <Alt><F11>
3. Open the Object Browser by pressing <F2>
The Object Browser allows you to visually navigate Word's class hierarchy. Its user interface is a bit crowded, so controls are unlabeled. Hovering the mouse cursor above a control will display a tooltip explaining that control's purpose. The browser's scope can be narrowed by using the Project/Library combo. Typing a keyword or substring in the Search Text combo and clicking on the Search button will cause all classes/members whose name contains the specified search text to be listed in the Search Results pane. Selecting an item from this list will update the two panes below it, showing the selected class, and its members. Beneath the Classes and Members panes is an untitled pane, gray in color, which displays details for the selected class/member, including hyperlinks to relevant information such as arguments, their types and allowable values. If Visual Basic Help is installed, pressing <F1> will display help on a selected class/member. (This feature can be installed from your Office install CD, if necessary.)
NOTE: While it is possible to cut-and-paste the code examples that follow, I highly recommend that they be typed in by hand. Doing so will provide a better understanding of how the IDE's code completion behaves. Use code completion most efficiently by not using the mouse or <Enter> key when selecting from completion lists. Instead, just type enough letters to select the desired list element, then continue along as if you had typed the entire element, typing the next operator in your statement. It really is slick!
HELLO WORLD - VBA-STYLE
1. Open Word
2. Launch the VBA IDE by pressing <Alt><F11>
3. Select Module from the Insert menu.
4. In the blank area that appears, enter the following code:
Public Sub HelloWorld()
Documents.Add
Selection.TypeText ("Hello, world!")
End Sub5. Press <F5> to run the code.
If you switch back to Word by pressing <Alt><F11>, there should appear a newly-created document containing the text Hello, world!.
A MORE AMBITIOUS EXAMPLE
In this example, we will launch Word, type some text, and alter its formatting. For the purposes of this tutorial, consider it the process we wish to automate from within Forms.
1. If Word is running, close it.
2. Open any Office application except Word, such as Excel, Outlook or PowerPoint
3. Launch the VBA IDE by pressing <Alt><F11>.
4. Select References from the Tools menu -- a dialog should pop up.
5. From within this dialog, locate and select Microsoft Word <version> Object Library, then click OK.
6. Select Module from the Insert menu.
7. In the blank area that appears, enter the following code:
Public Sub LaunchWord()
Dim app As Word.Application
Set app = CreateObject("Word.Application")
app.Visible = True '!!! IMPORTANT !!!
app.Documents.Add
With app.Selection
.TypeText "This is paragraph 1."
.TypeParagraph
.TypeText "This is paragraph 2."
.TypeParagraph
.TypeText "This is paragraph 3."
End With
With ActiveDocument
.Paragraphs(1).Range.Words(3).Bold = True
.Paragraphs(2).Range.Words(3).Italic = True
.Paragraphs(3).Range.Words(3).Underline = True
End With
End Sub8. Press <F5> to run the code.
A new Word session should have been launched. Switch to it, to view the results of our handiwork!
TAILORING VBA CODE INTENDED FOR OLE2 CONVERSION
Now, things get a bit uglier. The code listed above gives a good idea of how concise VBA code can be, but With blocks and chained object references do not translate readily into OLE2 code. Here's the same process, rewritten in a more OLE2-friendly style. Note the numerous intermediate object references that have been declared.
Public Sub LaunchWord()
Dim app As Word.Application
Dim doc As Word.Document
Dim docs As Word.Documents
Dim pars As Word.Paragraphs
Dim par As Word.Paragraph
Dim wrds As Word.Words
Dim sel As Word.Selection
Dim rng As Word.Range
Set app = CreateObject("Word.Application")
app.Visible = True '!!! IMPORTANT !!!
Set doc = app.Documents.Add
Set sel = app.Selection
sel.TypeText "This is paragraph 1."
sel.TypeParagraph
sel.TypeText "This is paragraph 2."
sel.TypeParagraph
sel.TypeText "This is paragraph 3."
Set pars = doc.Paragraphs
'select third word of first paragraph and make it bold
Set par = pars.Item(1)
Set rng = par.Range
Set wrds = rng.Words
Set rng = wrds.Item(3)
rng.Bold = True
'select third word of second paragraph and italicize it
Set par = pars.Item(2)
Set rng = par.Range
Set wrds = rng.Words
Set rng = wrds.Item(3)
rng.Italic = True
'select third word of second paragraph and underline it
Set par = pars.Item(3)
Set rng = par.Range
Set wrds = rng.Words
Set rng = wrds.Item(3)
rng.Underline = True
End Sub
TRANSFORMATION: CONVERTING VBA CODE INTO PL/SQL
Here is the PL/SQL counterpart to our previous VBA routine. Compare printouts of the two and note their similarities. Notice the need for argument lists -- this causes the code to fluff up quite a bit, and really interferes with readability.

CONCLUSION
It is my hope that this tutorial, despite it's introductory nature, has demonstrated the value of the VBA IDE, the ease with which automation processes can be prototyped using VBA, the noticeable similarity between VBA automation routines and their Forms PL/SQL counterparts, and the advantages of testing automation processes within the VBA IDE. Please feel free to follow up with any specific questions or concerns you may have.

FINAL NOTE: These examples use the OLE2 built-in, and will operate correctly when called from forms running in the Form Builder OC4J. Deploying them to an Oracle Application Server will launch Word on the server itself (if available), which is usually not the developer's intent! Automating Word client-side via web forms requires adding WebUtil support. Adapting the code for WebUtil is trivial -- just replace all instances of OLE2 with CLIENT_OLE2. Adapting forms for WebUtil and configuring OLE support into your Oracle Application Server, however, are beyond the scope of this tutorial.
REVISION HISTORY
This promises to be something of a 'living document'. I've snuck changes through without comment in the past, but in the future, I'll try to document significant changes here.

* Prefaced boring subject line with text: 'Tutorial:' to clarify purpose
* Added emphasis on value of Object Browser as a referenceThanks James, for your kind words. I do hope this information will help folks out. I honestly believe that tinkering around in the VBA IDE will prove highly gratifying for automation developers. It can be assured that learning to make Word jump through hoops is much more straight-forward in this environment. I'm not one for mottos, but if I were pressed for a cheesy motto, I would say: First, make it work. Then, make it work in Oracle!
Once the idea has sunk in, that Visual Basic routines for automating Word are exact analogs to their OLE2 counterparts, we can remove keywords like Oracle and PL/SQL from our Google searches on Word automation which, at least in this context, are the proverbial kiss of death. Suddenly we find ourselves liberated by the possibility of steal-, ahem... borrowing ideas from the Visual Basic* community!
As for links, my link of choice is invariably http://groups.google.com -- if you don't already use it at least ten times a day, you must try it. This is the venerable USENET archive, including the holdings of now-extinct DejaNews. Another possible site of interest is http://word.mvps.org/FAQs/MacrosVBA, which may serve as a good starting point for those who wish to learn how to do fancy tricks with Word using VBA.
If these links don't prove immediately helpful, please feel free to give specifics on the sort of operations you are interested in automating, and I'll see if I can post an example that addresses it.

Eric Adamson

PS: I do hope, as people read my posts, with every other acronym being VBA, that they are not mistakenly hearing a call to learn Visual Basic. I say this, not because I believe learning VB would be a Bad Thing, but because I assume that few of us feel we have the time to learn a new programming language. Despite having come to the Oracle camp already knowing VB/VBA, and having acquired a fair bit of experience with automating Office applications as an Access developer, I remain confident that what I am suggesting people attempt does not rise to the level of learning a language. What I am suggesting is that they learn enough of the language to get by.
*VB vs. VBA
Just a quick word on this, as readers may wonder why I seem to use these terms interchangeably. Visual Basic (VB) can refer to either a development platform or a programming language. Visual Basic for Applications (VBA) is a language -- more precisely, it is a subset of the Visual Basic language. One purchases VB, usually quite intentionally. VBA is included with Microsoft Office, as is VBA's development environment, the VBA IDE. The key distinction between VB and VBA is that VBA cannot be used to create self-contained executables. Rather, VBA relies on VBA-enabled applications, such as Microsoft Office applications, to serve as a container for VBA code, and to provide a runtime environment for that code. For the purposes of discussing OLE Automation, VB and VBA are quite interchangeable. -

How to develope some softwares to control 2 DAQ cards(5102)
We are trying to develope some softwares to control 2 DAQ cards(5102) to collect view and analyse the data. And set for sampling rate, time interval etc.
And we need to trigger the total 4 channels at the same time.
May you give any hints where should we start, any driver toolkit.
Best Regards,Depends on what you want to do, but this is one way to do it.
Configure task 1, configure task 2 (task 1 and 2 have the same hardware triggrer and both tasks are triggered to start on same signal either through RTSI or physically wiring). Inside of a loop, read task 1 read task 2 (depends on the relative rates of the tasks you might need 2 parallel loops) when daq is cone, exit the read loop and close the tasks.

Suggestion about Report Generation Toolkit
I'm adding report generation capabilities to a labview product test application. The report will be 2-4 pages long with text and plots. For other applications, I've used Word Templates in the past using VBA and Visual Basis 6. I had been planning to use the Report Generation Toolkit, but when I tried to run the examples Labview doesn't find the installation of Office, (I'm using Windows Vista). I've already read other posts about this particular problem and other issues with the Report Generation Toolkit for Microsoft Office, including upgrading to Office 2007 and beyond and I'm beginning to wonder if there might be a better longterm solution than the Report Generation using Microsoft Office.
The two alternatives that I'm considering are HTML, and Simplicity AI's PDF toolkit (free),
http://www.simplicityai.co.uk/products_services/products/pdftoolkit/
which I still have to investigate. I figure I could always generate in HTML and then print to PDF using something like PDFcreator (free).
If anyone has any comments/reviews/suggestions about the report generation from Labview, I'd appreciate hearing them.Hello PointOnePa,
What examples were you trying to run? Here's a good example on how to create report in Excel

When I bootup the icon for Elements shows up in orange. It changes to green only when I've gone to Finder and clicked on Elelments under the Devices list. This is a recent development. The icon used to be green upon bootup. Does anyone know why ?
I'm sorry to hear that.
I'm not affiliated w/ the developer, just a happy user that gave up fighting the apple podcast app a while ago. I used to have a bunch of smart playlists in itunes for my podcasts, and come home every day and pathologically synced my phone as soon as I walked in the door, and again before I walked out the door in the morning.
Since my wife was doing this too, we were fighting over who's turn it was to sync their phone.
Since I've switched to Downcast, I no longer worry about syncing my phone to itunes at all. I can go weeks between syncs.
Setup a "playlist" in downcast (ex., "Commute") and add podcasts to that playlist. Add another playlist ("walk" or "workout") and add different podcasts to that one.
Set podcast priorities on a per-feed basis (ex., high priority for some daily news feeds, medium priority for some favorite podcasts, lower priority for other stuff). Downcast will play the things in the priority you specify, and within that priority, it will play in date order (oldest to newest).
Allegedly, it will also sync your play status to other devices, although that is not a feature I currently use and can't vouch for. It uses apple's iCloud APIs, so to some extent may be limited by what Apple's APIs can do. -
Can I use my DAQ on two different computers?
Hi there.
Sorry if this might seem like a stupid question but I'm trying to save money lol. I have two test stations, each station has it's own computer and power supply. The power supply powers a certain device and the computer communicates with it via an USB to RS422 serial converter. I am using the 2 analog outputs on my NI-USB 6008/6009 DAQ to control the 2 power supplies. AO 0 to control the power supply on station #1 and A0 1 to control the power supply on station #2. I can control these 2 power supplies just fine with one computer connected to my DAQ. But i need each computer to be running tests independently. I only have 1 DAQ but 2 computers, is there way to use this DAQ on both computers???
thanks for any help!
Don't think twice.
Solved!
Go to Solution.No. Because there is no way you can take one USB-DAQ and plug it into two computers at the same time.
You would probably be better off having one PC that communicates with the USB-DAQ and have your application on one computer talk to the other computer to pass commands and get back data from the USB-DAQ, probably by way of TCP/IP.
I would actually make an application that only handled the USB-DAQ operation. Then have the program that runs on each computer be the same and talk to the USB-DAQ application which would act like a TCP/IP server. The program that is on one PC would call the IP address of the other PC. The program that is on the same PC as your USB-DAQ server would just call the local host to establish communication. -
The two DAQ cards are NI PCI-6070E & NI PCI-6052E. The Labview I'm using is labview 7 Express and the Window system is Window XP. I'm using NI SCXI-1000 chasis and SCXI-1102 & 1102B two modules plus a feedthrough SCXI-1180. 1102 is connected through SCXI-1349 cable to DAQ card 6052E while 1102B is connected through SCXI-1349 cable to DAQ card 6070E. SCXI-1180 is connected to 6070E through SCXI-1349 adaptor on the back of 1102B.
Sarah, thank you for replying my question. It seems that I'm making progress everyday (smile). I'm able to run the test using both daq cards in my code now. But as I'm moving forward, I'm getting new questions too. How do I use one STOP button to control both tasks and how can I save data into one single file?
I attached my code here hoping you can get the specifics on my application by looking at the code. Thanks very much!
Thanks.

How do I find the ports a pre existing program used in DAQ?
Hi all,
I am setting up a laser displacement sensor and trying to utilize a pre existing program that was created by graduate students before me. There are 4 wires coming from the laser displacement sensor that need to be connected to the DAQ but we have no information telling us where these wires are supposed to attach to the DAQ in order to run the pre existing program correctly.
Is there any way that we could figure this out?
Thank you for your help,
mccutchen12cJames,
Thank you for your help! Yes, we have looked at a couple different methods on how to tell if the information had been programmed by the previous grad students and we haven't had any success in finding that information. So I believe you are right in assuming its not documented.. We will do a better job of documenting for future grad students after us.
I have attached our code. Any insight you could give would be greatly appreciated!
We have an Acuity AR200-6 laser displacement sensor with green, yellow, black and a wire that isn't wrapped that all lead to the serial port in the back of the computer and ground. We then have white, blue, orange and brown wires that do not have a location.. We did some research and the are as follows:
white: laser disable
blue: buttons disable
orange: voltage output
brown: voltage RTN
We are starting to wonder if we are just not supposed to use the DAQ.. Can you confirm the connection is solely through a serial port?
Cheers,
