• average timed sub vi

  I train using the sensor data by sending one under vi I created, which will add a table in the sub vi every second, and then at the end of the set time out on average during this period and reset the table.  For some readon some of my data values are coming very badly.  Could there be something wrong with this vi? Specifically, I wonder if there is a problem with persistent data in the sub table vi...  I'm under LabVIEW 8.5

  You should be Subvi to be reentrant.  Go to the properties of VI-> execution.  There is a check mark there for reentrancy.  If you choose, you want to pre-allocate clone for each instance.

  What this will do, is that each call to the Subvi will have its own memory space.  He is currently sharing space and therefore your averages are getting all foires.

  I would recommend visiting the Journal of ground LabVIEW because there are some good articles on this subject this year.

• PCI6251: How to reduce widely AO size FIFO or Disable AO FIFO in AO HW timed DMA operation?

  I took aoex5 as a basis for the generation of signals timing hw AO0 DMA and it works well in my setup. At the same time two signals which depend on AO0 are measured to AI0/AI1 by hw-timed-DMA mode maximum rate (500 ksps / s) and it works as well.

  My goal is to apply a positive feedback mathematically AI1 to AO0 nationwide, and the easy way would be to change the values in the channel DMA AO AO rate on the fly, by reading the latest channel DMA AI values. The processor speed and the DMA space would be quite sufficient. The problem is that the CED are charged by means of a FIFO buffer that has a size of 8192 samples for my Board, and so to change a value in the buffer DMA would have no effect on the output DAC.

  I tried to simply disable the buffer FIFO of AO by setting AO_FIFO_Enable to 0, but it disabled the generation of signals AO together. Is there a way to disable AO FIFO and leave the DAC values directly from the buffer DMA? Or can I reduce the size of the FIFO AO programmatically to a minimum number of samples (2-16)? I could survive with a little latency induced by a small FIFO buffer, because I can compensate for this by changing the rate AO on the fly as well.

  I know, I use timed by the sw operations to achieve the goal, but I assume that AO DMA without FIFO operation would give me a lower latency of feedback.

  Thank you very much in advance for any helpful ideas.

  Hello Joe!

  I decided to start my experiments with the generation of signals AO0 clocked by sw.

  In order to test I put AI_Bypass_Cal_Sel_Pos-7 and AO_Bypass_AO_Cal_Sel to 0, while the generated signal is directly available on AI0. I was programmed to the maximum rate of dual channel (500 ksps / s) in a linear DMA buffer of 128 MB. To AO, I programmed a triangle (ramp-up/down) for a period of 2 V which is represented by 12975 AO samples.

  A tight loop software added an average across the last 4 Readings found in the DMA buffer to the AO value at the next exit, and once the LSB of the gross sample of AO changes, it is written to the DAC by Board-> DAC_Direct_Data [0] .writeRegister (Uc).

  I did tests with different speeds of scanning voltage from 0,1 up to 250 V/s. The AO to 250 V/s sampling rate was 1.6 MECH. / s. The deviation of the curve at the higher rate to the lowest rate is only 0.1%.

  Attached to this message you will find a diagram showing the magnification of the curves around the tip of the triangle. The Green curves taken at 100 and 250 V/s. Red to yellow to 0.1, 1 and 10 V/s. There are very low phase shift of 0.1% to scan rate of very hight perhaps due to the latency of your comments.

  Honestly 1.6 MECH. / s mode AO NI by sw including the algorithm of feedback far exceeds the expectations and I must admit, I am perfectly satisfied with this result. Sorry, Joe, but with that, I lost the inspiration to try out your suggestions, reducing the size of AO DMA buffer and change the FIFO AO mode. Anyway, thanks a lot for your answers.

• Moving average filter w / continuous data acquisition

  I'm looking to filter multiple signals of noisey. I am currently using a NI9203 w / a cDAQ-9174 sampling to 1000 Hz. I use DAQmx vi to start the task and acquire the signal. I tried using coefficients.vi smoothing filter combined with IIF filter.vi (Avg.png movement) it seems to work for simulated signals and recorded data. However, when I try to use this configuration for an average of real time it cut everything just all signals to zero.  I looked into the use of shift registers, but to get the necessary result, it seems that I have to use hundreds of items.

  In the end, I'm trying to filter the signal to get a constant more of reading for the user. For example during operation, the user needs to review the current state of the values in real time. It's currently difficult when the noise indicates the values of +/-100 changing every 100ms.

  For any help or suggestion would be appreciated, thanks in advance.

  Thank you all for the help and advice. I have attached the vi that I used to solve the problem, one of my major problems was not timing DAQmx using. Attaché in 2012 and 2013.

• Questions about an average of response spectrum and frequency of feeding mode.

  Hello

  I have a few questions about an average of mode. When I generate a sinusoidal signal from one output to two input channels channel to see if my DAQ card works well and vector averaged in the power spectrum for DFT, the amplitudes was different from the previous one of the amplitude, which was supposed to be 1 v peak. They range from 0.5 v to 0.6 v peak. When the calculation of the average model is RMS, the amplitudes were close to 1. I wonder what are the fomulas of RMS and average vector. Does that mean that I could not accurate if I use an average of vector? In a time of frequency response, why I coherences of difference and the amplitudes using the vector and the mean quadratic value?

  Thank you

  rico1985,

  The differences in modes of generation are as they sound: 1 sample output only a sample writing, N samples will be released however many samples configure you for each entry, and the continuous samples released samples continuously until a specified user action happens (you press the stop button or a logic that you created gets fulfulled). The range of Signal output allows you to set a ceiling high and low level of your output signal and it only affects the quality keeping in this beach. Timing to set a deadline for the time between the acquisition of the sample. If a new sample becomes unavailable before the timeout setting, you will get an error. This is useful for looking at a network, because if the network goes down and you stop getting data from a machine and then you would like to know about it. I point you to those videos that are short tutorials on how to make the most of these actions in SignalExpress.The SignalExpress 3.0 Help file is also your first point of contact for all your questions on getting started. These two resources should get you up and running in SignalExpress in no time. (either by the way all your questions answered using these resources) Bravo!

• Model in the loop timed While the elapsed time

  Hello NOR community,

  I'm trying to use a while loop timed to run controller simulated for a mechanical system test. I need the time loop to run at an even 50 Hz to simulate the controller that will eventually drive the mechanical system. To check the speed at which the loop runs, I made a VI that gets a value from each loop clock and subtracts the value of the clock of the current iteration of the value of the clock of the previous iteration. I have eliminated all other codes this VI except for the recovery of the clock, to ensure that no problem with another code in VI. I find that the time between iterations is not constant, but it is consistent. In other words, the elapsed time can change at each loop, but it changes according to a specific model, such that the average elapsed time is equal to the value that I use for the timed loop. The loop will run faster than posed for several cycles, then slow down during a cycle even at the same time. Here are some examples:

  Running at 5 Hz: elapsed switches schedules between 0.203125 and 0,187500 seconds

  Clocked at 8 Hz: time is constantly 0.125 seconds.

  Operating at 10 Hz: elapsed switches schedules between 0,109375 and 0,093750 seconds

  By examining the differences between elapsed time and the stability of the 8 Hz setting, it seems that there is a minimum time of 0,015625 seconds (64 Hz) division. It is much worse than the 1ms accuracy claimed in documentation. This could be the cause?

  I am running Windows XP with LabVIEW version 8.5.1 and have observed this behavior on several computers with different screws

  Thank you!

  Erik

  Your problem is the function that you use to get the current time.  It's just the time of the Windows clock which has a resolution of 16 msec.

  You must use the function of number of cycles as Jarle has pointed out.

• Workstation 8.0.6 and Win10x64: audio crackles - timing problem?

  I use WS 8.0.6 under Win7x64 on Clevo laptop P170EM (3610QM CPU, 16 GB of RAM).

  XP, Vista (32/64), Win7 (32/64), Win8x64, Win8.1x64 invited works extremely well, no problem at all.

  In all the Win10x64 invited (from 10586 last pre-release), the audio is very choppy, with or without VMware Tools installed.

  Tested with the internal ' Test' button and popular players (WinAMP, Foobar2000) using MS, SD and WASAPI interface. Even with 2000 ms buffering, there is no clear sound. In all previous versions of Windows (up to 8.1), 200-300 ms of buffering is enough.

  DPCLat shows 1200.15000 we 1100.1200 average latency.

  I'm afraid that there are some problems of timing of comments.

  What timing technique had been changed to relatively Win10 to Win8.1?

  WS 8.0.6 can be adjusted to fix, or should I update my WS to a version more recent?

  Would be - for upgrade, choose which version of WS? Here, I've seen a few complaints for WS 10 and 12 WS audio stability-related.

  I discovered that Virtual 8 HPET Hardware is enabled by default:

  hpet0. Present = 'TRUE '.

  Disabling HPET eliminates audio crackles and timing problems in win 8.x and 10:

  hpet0. Present = false

  (or you can just comment this line on ' # ').

  Most likely, Workstation 8 virtualizes not correctly HPET.

• Calculate the average per slot?

  Hi Chaps,

  I am a beginner on numbers (almost everything on Mac I would say) and I need help to calculate average values.

  These are calculated values (column 2) taken on a specific time of the day (column 1).
  I managed to create a third using a built-in function to get the time slot (column 3).

  This can help you

  

  Assuming you data in a table named 'Data' and the information is summarised in another table (right) named "Summary".

  Select cell B1 in the summary table and then type (or copy and paste from here):

  = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

  shortcut for this is:

  B1 = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

  Select cell B1, copy

  Select column B, paste

  I see something that will significantly reduce your performance: the connection points. Click on System Preferences > users and groups > login items and take a look at this list. The drop box starts up with the computer, as is Google Drive. These are the memory and CPU hog. In fact, outside the iTunes Helper, this entire list is probably to have an effect on the performance of the system.

  Try this: highlight each item, and then select the sign less down the list to remove. Restart the computer and run the EtreCheck again. I am betting, you will see a big improvement.

  You can add items one by one to determine which ones really is you get bogged down backwards.

• I get Connection Timed Out

  Recently, I've been doing the Connection Timed Out on some sites. I have cleared my cache and cookies, and it still happens. I tried in safe mode and it still happens. I don't know what else to do besides just uninstall and reinstall firefox, and I don't know if this will even help.

  Now, here's the real kicker. The warning is not always to her for the same sites, and sometimes almost randomly. For a long time that it didn't happen and now it seems to start up again.

  So I have really no idea what to do. Can someone help me please. Also, I'm a bit of a novice when it comes to the computer speak, so if you have a question that may be a bit overwhelming, could you dumb it down a little for me.

  To be honest, I think I understood the connection problem. However, the connection was reset problem seems to happen after I visit Deviantart. No other site does seem to cause the problem. Is that what I can do to avoid this problem, when I visit this site?

  Any ideas or advice GREATLY appreciated.

  Hard drives, like any other mechanical device, are prone to failure. That's why you kept backups.

  Don't forget that 'medium' no means half has no sooner. There is no need to compare an average to any specific device.
