LabVIEW 2010 FPGA: problem with the mean and the variance Subvi

• [FPGA] Problem with the sinusoidal signal generator

  Hello!

  At first I want to apologize for my English is not my mother tongue.

  Hardware and software I use is:

  LabVIEW 8.5

  NEITHER RIO 2.4.1

  NEITHER cRIO-9014 (controller in time real CompactRIO)

  NEITHER cRIO-9104 (chassis and FPGA)

  NEITHER 9264 (16 channels, +-10V, 16-bit voltage analogue output Module)

  I made a very simple FPGA VI: a while loop, generator of sinusoidal signal and a FPGA of e/s node in the loop. I've specified the Gnerator settings by following the path:

  Frequency = 50 Hz
  Amplitude = 1
  Phase shift = 0.00
  Size of the table look-up = 1024
  = 16-bit amplitude resolution

  FPGA clock frequency (40 MHz)

  But the wave of "sine" I got is not what I wanted to get. First of all, its amplitude is 1 V. shouldn't it be coded on 16 bits? If I wanted to get 1V I should have specified Amplitude as a 3277. In addition, 'sine' is not very detailed, it's look like "steps", as many samples vere missing. What I did wrong? I checked the samples and tutorials, I did everything the same way. A I forgot something or not has not specify other parameters?

  Thanks a lot for your help!

  OK, I solved a problem. It's embarrassing to admit, but maybe this will help someone else I blame my inexperience

  The main solution to the problem was changing calibration of calibrated RAW Mode. After that, everythoing works as expected. I had a problem with a sample because I was using a multiplier to control the generated sine wave amplitude. But... She was set to 1 in the sinusoidal signal generator. That was the reason for waveform Gradin. Please, don't laugh too much

  In any case, thank you for an answer! It is now resolved

• I have a problem with the simulation in Matlab 6.5 and LabVIEW for PID controllers

  I have a problem with the simulation in Matlab 6.5 and LabVIEW. I have a few methods for granting regulators PID in MATLAB to go but not of LabVIEW. Degree of international teams of two transfer but when I passed to the fourth degree is no longer working. We have changed the formula to calculate the parameters for the fourth year and gave me some good values for assignment of Matlab, but when I put on LabVIEW are not resolved. the formulas are available in PDF format and are. Please help me and me someone if possible. Thank you
  Lim.4 generation in comparison methods and the MATLAB program settings are for the service of transfer to the second degree.

  Hello Lascarica,

  I noticed that you are using the screw of PID. Gains on these screws are based on TIME instead of GAIN. You should be able to build a PID regulator and vary the gains and then compare the results.

• problem with timing cRio and FPGA

  Hello

  I develop software for measure the position of a device using some quadrature encoders.

  What I do uses the FPGA interface to acquire the position, then send usign real number of the meter to a host pc to create a data file. In the RT environment, I create a table with the position and the time that is acquired and using shared variables I send the array to the host PC.

  But I have a problem with the sync. The sampling time is unstable, I use a timed loop to control sampling but after some acquisitions, data sampling period begins to increase, as you can see in the image of attachment file. In the attached picture, I used a period of 250us and after some time gets twice and 3 times longer before you clean the table and begin to create a new table, during the period in 250us again. so the problem is that I should get a stable period in 250us instead of these steps in growing period

  You use the table of construction to add new data points? I suggest to use the function "Initialize the array" and "replace the array element. It will reduce the time it takes from the table of the construction.

  I can't open your code as I have LabVIEW 2010.

• Satellite C850 - found problems with the networking and the FN key

  Hey everybody,

  I work on a Satellite Toshiba C850, that my parents recently bought and spin in a certain number of questions.

  (1) wireless won't connect to my network. Have done the following: verified by connecting on two other computers, reset the router, the open network, reset the map, reinstalled the realtek drivers, checked the settings in the networking of Toshiba Utilities. End result is he's going to try, and fail. Wired LAN works fine.

  (2) FN key does not work. Have you checked the region and it is OK, have tried to use the Flash cards - no change, checked with the screen keyboard and can check the FN key does not register.

  I noticed that the first problem is common, but there are obvious positive results. If anyone can offer any assistance, I would appreciate it a lot.

  Before you begin to discuss your problems can you please tell us what OS you are using?
  Are you using the original OS that you got with your laptop? I mean original recovery image has been tested and works correctly, with the factory settings that all should especially the FN keys.

  1 / What do you mean with refusing? your WLAN is visible for your laptop?

  2 / if there is problem with the feature keys FN and you use Win7 try please reinstall extra package from Toshiba.

  I don't know about other issues. There are always 'problems' with any upgrade. You weigh against the benefits. I know that you need more RAM. At least 4 GB, maybe more if you can. Don't forget that this system is produced at a time when most of the machines have + 8 GB RAM and when Apple said 'minimum' they really mean it.  I recently inherited a MacBook that has 2 GB of RAM and the Mavericks. When I checked the memory, the use of the system was using 1.95 GB = nothing to run applications!

  I am facing a problem with the beep.vi.  I have a DAQ program, which acquired the signal and compare it to a threshold value. When a signal is out of range, a Visual and sound alarm has occurred. I use the VI beep.vi to generate the sound. Everything works fine except the sound alarm. It gives the table 1 d of type mismatch. I tried to fix this by placing it in a box structure. But it still does not work. If someone could help? Please find attached my VI. Best wishes to all visitors to the Forums of Discussion OR.

• Anyone know if there is a problem with the "Windows Update" site? Since May 11, 2010...

  Anyone know if there is a problem with the "Windows Update" site? As of May 11, 2010 I could not access it for 2 days now.  I get an error report indicating that he has a "problem with the site '... Not sure if it's my computer or the site itself. I just need to check updates and download them. I would be grateful for any feedback...  Thank you!
  ~ Jenifer

  It is without a doubt.  There were a few patches published today, and I was able to update all my machines successfully.  This looks more like a virus problem.  Have you run a virus scan recently?  Many times, if you are infected the virus will prevent you to access Windows Update.

  You can also use Microsoft Fix It to reset the Windows Update components: http://support.microsoft.com/kb/971058.  This could also be your problem.

  Let me know how it goes,

• Problems with the resource of labview execution 2 visa

  I use two loops in a labview code all-in - connects to a motor controller and other is used to connect to a multimeter agilent. As soon as I run this VI, the loop to connect to the controller stop working and only used to configure agilent machine works. If I remove the second loop (connecting to the computer of agilent), the code works fine. I guess it's a problem with the execution priority. Could you please review the attached code and let me know any problems with it.

  COM1 and Com3 share an interruption.

  Go to the BIOS of the computer and set the port to Com3 to the Com2 port, then they will be on their own interrupt and see if that helps.

  FYI

  COM1 and Com3 share IRQ3

  COM2 and Com4 share IRQ4

• Problems with my mouse, and have not been able to find a solution to the research on various forums.

  Original title: mouse problems

  I have problems with my mouse and have not been able to find a solution to the research on various forums. Here are the symptoms:

  1. you must click several times to get the menus to open. Sometimes they are not just and sometimes they open with a single click flash but do not stick until I clicked several times.

  2 several times the menu drop down and seem to become transparent (not in looks) because when I click on something on the menu, he actually selects everything that is behind the menu drop down. For example, if I'm in powerpoint and you select an item in edit mode, it might work and here again he can just select the slideview behind the menu and expand. Or well, if I'm on a Web site, such as Facebook, and I chose to close the session, rather than enable the disconnection of the key, he chooses some ad is behind the part of the menu and redirects the page of this Web site.

  3. when I try to select a Word, words or sections as paragraphs, it performs several different things: continually select as soon as I let go of the mouse button, the jumps of color selection in another part of the document, or deselects the part of the text before I even let go of the mouse button.

  Here is what I tried:

  1. I had originally a usb wireless mouse. I changed the batteries and then got a new. Now I use a wired mouse.

  2 make sure all updates for Windows and Office 2010 are updated.

  3 has tried to update the drivers mouse, says that it is up-to-date. He restored, did not work. Uninstalled and restarted.

  4 Ran Windows Security Essential and Malwarebytes - found nothing.

  5. ensure that all the Toshiba updates were up-to-date.

  I don't know how the word this issue properly in order to find information about it. Everything I typed in search engines brings me other problems unrelated to this one.

  I am running W7 64 x Home Premium SP1, SP2 MS 2010 with a mouse Dell; Toshiba Satellite C655

  Well I have stumbled on the fix... looks like there was a problem with the HID-compliant mouse. The convenience store hardware detected and solved the problem. Everything seems to work properly again.

• I had a few problems with the search engines and history

  My default search warning back to Yahoo after a reset on my computer. Close Firefox keep one to change but by restarting the computer, it takes.

  I can't open the sidebar history. The option "view the history of your" opens its tab fine (the drop-down menu that says 'Show History Sidebar', 'clear recent history... ("ect.). But, when you click on the "Show History Sidebar", nothing comes. Can I use the "Show history" option, but the sidebar does not open for some reason any.

  I just finished with a complete analysis of the Microsoft Safety Scanner and it said not that there is anything wrong. I have not reset the computer again to see if something has changed although after the factory reset (see the 2nd paragraph) it seems returned to Yahoo (search engine he kept going to happen).

  I open the history tab in the menu of the toolbar, and everything seems fine here. I also had him always use private off all first browsing mode. After activating the option clear history when Firefox closes, I ended up having to reset to factory settings (things he saves were saved isn't really a problem) that doesn't seem to fix the problem with the sidebar of history not to come.
