Is it possible to change the sine wave 'exit' a simulation device?
I work on a LV collection and analysis VI in LabView that interfaces with a CDAQ-9178 loaded with 9215 modules/a. chassis. In the Measurement & Automation Explorer, I was able to set up simulated devices that work with my code and I get the sinewave / 5 (?) standard signal noise %.
However, to really test my application, I need a slightly different sine wave with high frequency (1-10 Hz vs the)<1hz sent="" by="" the="" simulated="" device). ="" is="" there="" anyway="" to="" modify="" or="" get="" the="" simulated="" device="" to="" output="" a="" different="" wave? ="" if="" not, ="" are="" there="" any="" other="" simple="" ways="" to="" simulate="" the="" device? ="" i="" could="" write="" another="" vi="" to="" send="" out="" a="" sinewave="" but="" was="" looking="" for="" a="" more="" obvious="" or="" simpler="" solution="">1hz>

# You need to do is call an of the generating functions of waveform instead of the DAQmx Read. Place inside a case, the declaration or the conditional structure disable is fairly simple.

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

Simulate the sine wave using LabVIEW FPGA with NOR-myRIO and display in real time
Hello
I'm relatively new to LabVIEW FPGA. I am trying to test (and later apply) controllers high speed on myRIO.
At this point, I'm trying to simulate the sine wave from 1 to 10 kHz using Sinewave generator VI express. I also intend to display the sine wave on the time real (RT) using FIFO. However, I had a bit of trouble to understaing various synchronization parameters.
1. how to encode information about the sampling frequency generating sine wave? (The side FPGA vi requires only the frequency of the signal and possibly phase and does not rate update lines)
2. how to estimate the number of items in a FIFO? (that is, the relationship between the rate of updates to loop (RT), the signal frequency, sampling frequency and the number of items in the FIFO)
It would be great if we could share a very simple program (side host and target) that did something similar.
Thank you
MILIN
Milot,
I think the problem is the type of data in your FIFO. Your FIFO is configured to use a data type of I16. The problem is the number, it displays only ever will be-1, 0 or 1. To resolve this problem, you must send the sine wave as a fixed point data and convert it to a double on the side of the RT. This should significantly improve your resolution.

Is it possible to change the default channel strip settings?
Is it possible to change the default channel strip without having to depend on models?
For example, I always wish to have:
- Follow the value Name = 3 lines instead of the default line 1.
- 'Follow the icons' checkbox deselected
- Always follow box color
- Control surface Bars always deselected
Stuff like that... This apples to any screen that is affected by the Configuration of channel strip window. (View mixer or titles).
Thank you!
Is it possible to change the default channel strip without having to depend on models?
NO.
But why not use a template? You use a template of this moment anyway, the default value of project. Just change and set the Start Action that you configured

possible to change the font size of the bookmark toolsbar?
possible to change the font size of the bookmark toolsbar?
upgrade to firefox v22 and notice this bookmark toolsbar got bigger, some bookmark font cannot be displayed, it is normal? possible to change?Hello
Firefox on Windows is now after display, scaling options that can make the biggest text on screens at high resolution.
You can adjust the resolution of your screen.
To change it follow these steps:- Type of topic: config in the Firefox address bar and hit the Enter key.
- If the warning that this might void your warranty , click I'll be careful, I promised.
- Search for layout.css.devPixelsPerPx
- Double-click layout.css.devPixelsPerPx to edit its value. The default value is - 1.0 in Firefox 22 and above. Change it to 1.0 to run as in previous versions of Firefox.
If necessary, further adjust the value of 0.1 or 0.05. Values between 1.0 and around 0.5 to reduce the size of the elements. Use a value greater than 1.0 to increase the size. For example, a value of 1.25 will increase the font size of the 125% to account for the default DPI setting in Windows 8. Check the value that you enter. Definition of a value that is too small will take everything away and too high will explode things.
If the web pages should always be adjusted so you can watch the extension Default FullZoom Level or NoSquint .
To adjust the font size for the user interface, you can use the extension of theme font & size changer .
This solve your problems? Please report to us!
Thank you.

Satellite Pro M70 - ist is possible to change the craphics controller?
Is it possible to change the graphics controller to my Satellite Pro M70...
If so, where to buy a new one?THX
Hello
Well, in general it s is not possible to replace or update the graphics card.
But I compared a Satellite Pro M70 unit because this series of laptop was delivered with different hardware configurations and I found that these installed graphics cards:
Mobile Intel 915GM Express Chipset AlvisoGM 8 MB to 128 MB shared video memory
ATI MOBILITY RADEON X600SE 128 MB of video memory
ATI MOBILITY RADEON X 700 256 MB of video memoryHowever, in my opinion you can not change the graphics card

Is it possible to change the link to the WMP to Play/Pause/Stop buttons
Is it possible to change the link to the WMP to play/Pause and the Stop button?
Because network alone and media buttons can be changed by the software.
And I'd rather not WMP for my favorite media player.Unfortunately, the buttons are configured with WMP (if the CD is inserted) and WinDVD (if the DVD is inserted).
I guess that you can not use buttons with 3rd party applications. -
Satellite M70 356: is it possible to change the graphics card
Hello
I want to buy Windows Vista (Home Premium). But I also want to activate Vista Aero Glass Style.
I downloaded a Microsoft tool, who told me that my (INTEL 915GM Express) installed is not supported...
Is it possible to change the interface? How much would it cost?
Is it really impossible to run Vista on my laptop (with the new skin)?Hello Stephan
You can run definitely Vista on this laptop. I installed Vista on my Satellite M70, but unfortunately this Aero Glass Style option is not available.
I put t know why it's so important. OK this is very interesting feature, but you can still run Vista without it.

Thanks in advance and sorry for my bad EnglishAt first, I must say that your English is very good and understandable.
Back to your question: update graphic card is not possible. The graphics card is part of the motherboard and cannot be exchanged separately.Please note that the portable is not so extensible as on desktop computers. The upgrade can be done with RAM or HARD drive very easy, but not with processor or graphics card.
