• The sine wave generation

  Hi guys,.

  Sorry I have a very simple problem. But it seems that I am too new to LabVIEW... and / or have no idea. I've tried a few things but nothing worked propperly.

  I need to generate a sine wave with the following of the flexible parameters.

  f = 0.02 Hz... 10 Hz

  Range = 0... 500

  Offset of 1500

  I would like to see a cursor moving and get off after the sine wave. The parameters should be changed at any time that the generation of the sine wave inside a While loop. If that would work I intend to integrate that in the code I wrote for an Arduino, Makerhub, slavery... The values already referring...

  I tried allmost all the generation of singnal live that I could find but nothing has worked. Calendar completely proven on a waiting insid the while...

  Frequencies below 1 Hz is the fast cursor again... WTF...

  A sinusoidal 1 Hz signal should make the cursor up and down 1 times per second... or am I totally wrong.

  Ah... Perhaps another question. If possible, I want to count the period. For example, after 4 times of the sine wave stop all programs.

  Any help apprechiated... I work with LabVIEW 2012SP1

  First of all, please understand this waveform generating function works. You specify a waveform (amplitude, frequency, etc.) and whenever you call the function, it returns all the wave specified points.

  You can set the number of points with the #s of the info of sampling pole control. As you put the function in a loop, each itaration gives you #s number of points (1000 in your case). You always get a sine wave on your cursor because each iteration returns a different set of 1000 points (this is because of the method, the function calculates the waveform).

  The easiest way to create a sine wave is using the sinus (mathematics, primary, Tigonometric, sine) function. You must use the iteration of the I of the loop counter so that the entry of the sine function. Note that the entry is in radians.

  With a little math, you can easily produce and display a sinusoid at 1 Hz.

  

  Kind regards

• The Essential Guide to Dreamweaver CS3 with CSS, Ajax, and PHP by David Powers

  The Essential Guide to Dreamweaver CS3 with CSS, Ajax, and PHP by David powers:
  
  This book would help me learn more about Spry and Ajax and how applications may be lodged with them, if I have my e-commerce site works on a compiled C code cart (ShopSite) but supports scripts PHP server-side or is - this only for shopping carts based on PHP itself (like X-Cart)?
  
  I'm not sure. Someone please let me know if I can buy this book. Thank you.

  You don't need no prior knowledge of PHP or Ajax, but you must
  know the basics of HTML and CSS. As I say in the introduction, "You."
  don't need to be an expert, but do not have a curious mind.
  It teaches the basics of web site design, or he's trying to list
  each unique feature in Dreamweaver CS3. There are many other books
  to fill this gap. However, by working through this book, you will gain a
  in-depth knowledge of the most important features of Dreamweaver.

  The book provides detailed coverage of the features of Spry 1.4
  Dreamweaver CS3, which can be applied to any site. With minor
  adjustment, you can also use Spry 1.6. It is important to realize,
  However, the features of Spry/Ajax in Dreamweaver CS3 * cover of no
  asynchronous requests to the server. The ability to communicate
  asynchronously with the server has been added in Spry 1.6. If it has
  the asynchronous server calls and answers you are looking for, your
  programmer will need to dig into the documentation for Spry 1.6 on the
  Adobe Labs site and manually code it.

  The Spry features covered in the book are Spry, Spry UI widgets effects
  (menu accordion, tabbed and folding panels), Spry
  Widgets of validation and Spry XML data sets.

  Yes. All Spry techniques can be used on any web page. This is not

• Problem of using IE 8 with Hyperion Planning and workspace

  Has anyone tried using IE 8 with Hyperion Planning and workspace? I found that sometimes it has the error message and cannot allow users to log out.

  Hello
  We tried IE8 with system 11. It simply doesn't get it. IE8 is not officially supported yet. And over the years, I have learned this lesson: never use a new browser, unless it is officially in charge.
  You can find a page very useful here in this link to see what is currently supported for your release.

• Display in real time with a delayed recording LV6.1

  Hi, I need help with LabView 6.1

  I have a hardware module FieldPoint where I read 8 channels for thermocouple. I want to display the value of the thermocouples in real time (or as close as I can manage) all saving the values in a CSV file at discrete time intervals (every 10 seconds). I am able to display the values in real-time, but the recorder real-time records, produce a lot too much data. I'm able to delay the recording interval, but in bulk then display in real time!

  The following example shows a method I've tried. The delay time in the loop of logging seems to delay the entire program. I also tried to use the loop of the logging of a sequence (using a simple delay of 'Wait') structure and a structure of matter (with a counter and only do the loop of logging real when the counter gets to 1). I tried to configure synchronous display without success.

  I'm having no luck and wonder if someone could point me in the right direction?

  Ah, the benefits of time.

  I think that I managed to create a solution for me using a different tact. Instead of using individual meters of delay, I used a "trigger time" approach as demonstrated in this thread;

  http://forums.NI.com/NI/board/message?board.ID=170&message.ID=286988&query.ID=6280650#M286988

  Currently, it is limited because it will allow only a delay of 59 seconds between the readings, but this should be relatively easy to solve. The solution works continuously update the display with a slight delay to help cope aging computers, and then the button "Log Data" is selected writing worksheet function is called second pushed together as selected. Quite a simple and elegant solution I think.

• In version 13.0 is selected the option "when Firefox starts to show my windows and tabs from last time", but I always get default page of Firefox.

  Even thought is selected the option ' when Firefox starts to show my windows and tabs from last time "I always have the default page of Firefox.

  Hi Goldie_,

  I guess you don't watch this page when you closed Firefox last time. Also that you are not in private, correct navigation mode? Looks like it is maybe a problem with Firefox being able to save your file pref.js. You should try the steps listed in the preferences section that won't save trouble. Try and let me know how it goes.

  Hope this helps!

• Acquiring temp with NI 9214 using labview fpga

  Hello

  I'm a student, very new to labview and data acquisition. I had problems with a thermocouple type T of wiring to a NI 9214 module and writing a program labview FPGA to acquire temperatures. I've been struggling with this and for a long time to research on the web without success.

  Please find attached the code that I work with. I was told to use the value obtained from the CJC and converted using the formula I found here ( http://zone.ni.com/reference/en-XX/help/370984T-01/criodevicehelp/9214_converting/ ) and arrays of conductor thermocouple type T to find the temperature, but I didn't get anything that makes sense.

  Please can someone help me?

  Jeremiah

  Hi Jeremiah,.

  You use this 9214 in cRIO chassis? If Yes, which model?

  Regarding the conversion of the data, you have to take care to recover the data from the side host (you'll need a separate VI) and taking care of converting it. When you mention that you don't get what makes sense, what exactly read / do you expect?

  I strongly suggest you open and tinkering with the example of the host/FPGA shipping screw to the 9214 (NI 9214 Get Started.lvproj, found in the program NIUninstaller Instruments\LabVIEW 2013\examples\CompactRIO\Module Specific\NI 9214\NI 9214 Getting Started). It should allow you to have a good knowledge in understanding the relationship between the host and the screw of the FPGA.

  I hope this helps!
