Hardware and software CAN measure entered differently?
Hi, I'm an application that measures the speed of the wind using crio-9012 and NI 9423 (DIO)
I have the sensor that generates output voltage at different orientations so when he gets shot it generates a type pwm duty cycle 50% wavefrom
When measured with the higher wind speed, it will be generating the signal with greater frequency
Now using labview, I'm trying to see if he can show me the right of the signal as I saw the scope, but it does not show me a good performance
When I rotate the sensor, the light of NI 9423 seems to blink at the right frequency (meaning work) but led I did LabVIEW flashes at a different frequency, not really to work
I don't see how this happens when both LEDs are managed by the same code, the diffrenece is a material is and the other is software
What should I do?
I think that's the problem. Your code is very simple and there is nothing really go. This means that the LED will change very quickly in the resolution of Nova Scotia. The way you look at the façade of the FPGA VI is made using what we call the Interactive Communication of front panel which is not deterministic. This means that as the target FPGA block diagram continues to run, the host updates the values in the FPGA VI front window as often as possible. But, it is not possible to update the rate the FPGA VI running, nor is it possible to transfer this data to the host at that rate there since both are running at different speeds (FPGA your code runs at ns while the UI can be updated by ms). Let me know if you do not understand this.
Communication interactive front panel
If I were you, I would test the flashing by placing a kind of counter and count the number of state changes.

I have a system of 3 GB/500 GB HD in Inspiron 530 Dell, Vista Home Premium 32-bit. I need to restart more frequently and the system works more slower and slower... so I think the upgrade. Can I move to a 64 bit OS in Windows 7 or 8 and keep the same hardware and software, applications that I already like Office 2007, Photoshop Elements, etc... ? What are the benefits to 64-bit?
Hello
There is no way to upgrade from 32 bit to 64 bit.
It should be down with a clean install.
Go to your computer / computer laptop manufacturer Web site and see if Windows 7 drivers are available for your make and model computer / laptop.
If this is not available, Windows 7 will not properly work for you.

This is a CAD program that requires a lot of ram and a transmission of data high-speed HARD drive.
To do this, it is absolutely necessary to update hardware and software for civil use with good performance.I need to buy and install HDD SSD, install more RAM (which is the maximum allowed in this computer?) and I need to install Win 7 Professional 64 bit.
Please,
If anyone can tell me how I can further improve the performance of the laptop, please tell me.
I don't know what steps I need to keep.Can you help me?
Thank you very much.

There are many applications no longer works on ios5.1.
At Apple archived older versions of applications and will make available this backwards compatible?
Developers can submit apps for obsolete equipment and iOS version outdated on the App Store?
Does iOS App Store allows the old inherited app to download to support more hardware and software?
Thanks for your help.
You can download older versions of applications if you have a computer or other device running a newer version of iOS. This explains how do.

difference in the hardware and software calendar
Hello world.
I have a few questions about the time of hardware and software.
1. What is the difference between hardware and software?
2. What does hardware mean? PC or DAQ as usb 6211?
3 when I use "DAQmx Timer", it means that I use the hardware timing?
Thanks for your help!
Hi Xiang00,
>> 1. What is the difference between hardware and software?
Hardware timing is more accurate, because it uses the on-board clock. Avoiding the is less precise because it depends on the performance of the PC.
>> 2. What does hardware mean? PC or DAQ as usb 6211?
"Hardware" means the hardware such as USB-6211 DAQ.
>. 3. when I use "DAQmx Timer", does this mean that I use the hardware timing?
Yes. You can find more information in the knowledge base DAQmx Timing and sampling frequencies.

I have officejet pro L7590 - my print drivers are the HP Universal print driver. I would like to load the software and drivers for the original L7590 because I lost the HP Solution Center. I downloaded the software and complete drivers for this model and tried to install it, but it tells me that I have updated drivers and it does not reinstall drivers print and software. When I look at my file to the printer, it does not show my printer. What can I do to get off the universal drivers and reload the original drivers. I tried to uninstall the HP Universal drivers, but it does not appear in my programs. Any help would be appreciated. I also tried of revo uninstaller to uninstall the universal print drivers, but that has not worked.
I am running Windows XP

Living green screen broadcast and record--hardware and software that? DESPERATE
I want to install a stand (for example in a mall) where I can give an opportunity to people to play in their own movie, and they will receive a DVD directly after them filmed.
Here is an example of what I mean:
There is a green screen with a car toy, big enough for a child to sit in front of the screen. A parent pays me to their child playing in their own movie. The child is sitting in the car for 3 minutes to play with the steering wheel and pretend to be in a race. This 3 minutes is recorded on a video camera, as well as the green screen being Footage.com on showing the child in a race on a large TV that draws the crowds. Straight afterwards, the customer is given a DVD of their movie.
In addition to the necessary specifications:
I want images in high definition for the film on DVD
I want to be able to save this movie because it is made - 4-5 minutes of when the child is sitting in the car to get the DVD as to maximize the income per hour.
I am wanting to know what software of the Production Premium CS 5.5 software will flow direct to the TV and record it on the DVD on the computer - I know that I can listen to the TV and use a DVD recorder to tape whats on TV, but apparently it's not reliable.
-Apparently Wirecast can do-
You mix the processing part of physical signal with real software processing. Of course, Wirecast can accept HDMI streams, but you still need a compatible HDMI capture card to your system to get the data from your camera to the computer. It can then simply forward / blindcopy HDMI streaming to a LCD screen without secondary treatment, but it's another matter entirely. As part of the exercise is negligible in comparison, actually do in your system is the most difficult part and that cannot be done with specific in the case of HDMI because of HDMI licensing equipment works and how it imposes a managed copy protection / digital rights management down to the chips used in the decoders. Once the flow of data into the software, of course, the program is free to manipulate or show-which is not different from that first or OnLocation do in their live preview. Still, in the case of Adobe software, you can not be run effects as a live on the stream manipulator entering as you would in wirecast, Tricaster or other dedicated production systems live upward to live mixers professional of one hundred thousand dollars. So no matter what, you'll have to invest in some hardware, whether just a box to capture external Matrox 'cheap' or something similar to AJA or Blackmagic...
I need a quality that is not pixelated to display on a TV at home when people take their DVD at home to see. Suggestions on the resolution?
The quality is determined solely by the implementation correctly in the first place, and the transcoder chips used in DVD recorders. This could be as simple as plugging your HDMI signal or Composite of the recorder and to choose the 'best' quality setting or too complex to have to look through hundreds of menus to find the correct settings. Over the years we use several Panasonic and Toshiba recorders of DVD in our facility for customer quick & dirty review recorded footage DVD or the occasional holiday or wedding video and have always been satisfied within what we expected, but of course, there are limits. It would be preferable if you have tested this in your local electronics store preferred passing a few minutes and burning a DVD test, if possible. Impossible to be more precise than that. There are just too many variables, including the fact that, in the United States, other models are sold as AAR here in Germany...

Hello:
You can try the following steps to see if you can get XP to work on your laptop.
First of all, download this file and use the free 7-zip file utility to extract the files from the exe.
7-zip:
You want to integrate all the files found in the drivers > x 32 folder.
Then you can see if the 4540 XP drivers of HP Probook work on your model. They can operate with the exception of the card reader.
For audio, you must first install the MS UAA driver and restart the computer before installing the audio driver IDT.
For the card reader, the driver is the file second or third on the list of the ether.
