• How to calculate the execution time of a SCTL in FPGA VI?

  Hello

  Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

  Thank you and best regards,

  Rashid

  Hello r,.

  A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.

• To build the waveform.vi function how to calculate the value of dt

  Dear all

  Please guide me How to calculate the value of dt according to waveform.vi of construction

  My sampling rate is 25000 and I take 200000 samples.

  Kind regards

  It's all simple arithmetic. The inverse of the sampling frequency power of samples is then the dt or the time between samples the number of samples is not relevant.

• Series Packet Question: How to calculate CRC

  Hi all, I have tryied to find an answer on how to calculate the CRC on a RS232 packet received, its really driving me crazy!

  im a beginner, learned how to use labview read on different forums, and I had managed to build really good applications, but im stuck in this, hope someone can help me...

  OK, so im constantly receive packets of 15 bytes:

  A5 09 0C 00 61 05 1F A0 10 00 05 00 04 05 3F

  A5 09 0C 00 61 05 10 00 05 0C 2F 03 A0 1F-3F

  A5 09 0C 00 61 05 10 09 05 09 04 09 A0 1F-3F

  the supplier for material gave me the following code to calculate the CRC:

  Control CRC program:

  #define unsigned char uchar
  UCHAR CRC_Bitwise8 (uchar * buf, uchar size)
  {
  UCHAR i, j, b;
  UCHAR crc = 0;
  for (j = 0; j<>
  {
  b = * buf ++;
  for (i = 0; i<>
  {
  If (((CRC^b) & 0x01)! = 0)
  CRC ^ = 0x18;
  CRC > = 1;
  b >> = 1 ;
  }
  }
  return crc;
  }

  so my question is, how can we insert this code in labview? any example?

  Thanks in advance, this forum has really helped me learn labview in a practical way.

  You can use my code for the thread that I've referenced.  To play with a web version of my code go here. My code is based on the code on this Web site.

  My code to the following parameters:

  Calculation of the CRC: Other (specify)

  Order of the CRC: 8

  Polynomial CRC: 0 x 30

  CRC initial value: 0

  CRC XOR final value: 0

  Reflect the preprocessing of data: TRUE

  Match the data before Final XOR: TRUE

  In your messages, the A5 09 0c is certainly a header.  I think that the 00 following is also part of the header, but without the manual, I can't confirm.  00 will not affect the calculation of the CRC, in order to get the same results with it and without it.  So, in your first example, I use 61 05 3F 1E A0 00 05 00 04 10 and the result is 0x05.

• the time of acquisition of data - how to calculate the rate of analog output

  I want to calculate an acceptable rate of analog output, one that is taken in charge by material (PCIe6353), without the rate being changed by the VI DAQmx Timing (sample clock). The final objective is to have a rate of analog output that is an integer multiple of the analog input for precise frequency, since the sinusoid AO's amplifiers, which have a ringtone when AO updates occur.

  According to 27R8Q3YF of the knowledge base: how the actual scanning speed is determined when I specify the rate of scanning to My d..., the rate is revised as needed by calculating the rate of clock / asked for advice, divide the result rounded downwards and upwards in the clock of the Board and use the one that is closest to the requested speed.

  If 'Embedded clock' is selected, which is the result "Council clock.  DAQmx sample clock timebase Timing node - SampClk.Timebase.Rate says 100 ms/s. However, for a rate resulting from the update of 2.38095MS / s, the divisor of the time base timing node - "SampClk.TimebaseDiv" gives a value of 42. 42 x 2.38095 M = 99, 999, 990, where it should be 100 ms/s.

  How to calculate an acceptable rate of analog output is supported by the hardware? I have other plates, in addition, a general method would be appreciated.

  I haven't worked all the details yet but noticed a few things that may be relevant.

  Req AI rate isn't a whole ditch 1E8. It is used to determine the rate of the AO.

  There is no check to ensure that the rate of the AO is an integer division.

  It seems that you have the right idea, but the implementation is not yet there.

• How to calculate the polynomial graphic adjustment of waveform

  Hi all

  I am new to lab - view so would need a little assistance in one of the problem I have right now.

  My problem is: how to calculate the polynomial graph of waveform data adjustment? I need to convert the waveform to XY graph data, and then use the polynomial vi made integrated to calculate the fitting?

  Detail: My problem is that I have waveform graph, I calculate the vertices and the Valley, but because of the noise, my peaks and Valley detection is sometimes not exact, so to smooth the chart that I must apply the polynomial fit.

  If anyone can help me in this, I'll be very grateful.

  Thanks in advance

  Hi Omar,.

  have you seen the suggestion of Lynn above?

  You already have the values of Y (your table). Now, you need build the table of X as indicated, only to replace the value of dt with your spacing from point to point. Somewhere in your code, you know that the value that you have an x-axis indicated in milliseconds...

• How to calculate the CPU Ready on Cluster DRS via Powercli?

  Hi all!

  I have a DRS Vsphere cluster. I want to know what is the value of the loan of CPU I have in my group.

  For example, I get 20% of powercli value, it is normal for the cluster, but if I have 100% or more, I have a problem.

  How to achieve via Powercli? And how to calculate the percentage values correctly?

  I know, I can get all values of CPU Ready of VMs cluster, but IT is not the same thing, I need overall value of CPU Ready.

  Thanks in advance!

  As far as I know you can get the cpu.ready.summation for ESXi nodes or VMs.

  For a cluster, you will need to get the value of each node in the cluster ESXi and then take the average.

  The metric cpu.radey.summation is expressed in milliseconds.

  To get a percentage, you need to calculate the percentage of loan period during the interval during which it was measured.

  Something like this (this will give the loan current %)

  $clusterName = "mycluster.

  $stat = "cpu.ready.summation".

  $esx = get-Cluster-name $clusterName | Get-VMHost

  $stats = get-Stat-entity $esx - Stat $stat - Realtime - MaxSamples 1 - forum «»

  $readyAvg = $stats | Measure-object-property - average value. Select - ExpandProperty average

  $readyPerc = $readyAvg / ($stats [0].) IntervalSecs * 1000)

  Write-Output "Cluster $($clusterName) - CPU % loan $(' {0:p}'-f $readyPerc).

• How to calculate the sum of two digital form fields based on the selection of the checkbox.

  I have a form in Acrobat Pro who needs a custom calculation. How to calculate the sum of two digital form fields based on a selection of the checkbox. I have three number fields. Field-A and B are simple one or two digits. Field-C is the sum, or the total field. I want to field-C have a control box which, when turned on and off, just gives a. gives the sum of A + B

  _ Field - 2

  _ Field - A 4

  [check] _ _ field - 6 C

  [disabled] _ _ field - 2 C

  Thank you

  The custom field C calculation script could be:

  (function () {
  
      // Get the values of the text fields, as numbers
      var v1 = +getField("A").value;
      var v2 = +getField("B").value;
  
      // Set this field's value based on the state of the check box named "CB"
      if (getField("CB").value !== "Off") {
          event.value = v1 + v2;
      } else {
          event.value = v1;
      }
  
  })();
  

  Replace 'A', 'B', and 'CB' with the real names of the fields.

• How Illustrator calculates the height of box Em?

  I am trying to determine how Illustrator calculates the basic position of the top of the a Point text object bounding box.  She seems to be the same distance as an object of text box with the game setting of first base to box Em height line.  I just do not know what assets within the scope of the police which matches.  Help of the Illustrator defines it as:

  "The top of the box em in Asian fonts touches the top of the type object. This option is available regardless of the preference show Asian Options. »

  For some fonts, this distance seems to be near the pole of the police, but this is not true for each font.  The clues how Illustrator calculates it?

  

  Here you go

  var idoc = app.activeDocument;
  var itext = idoc.selection[0];
  
  var top = itext.position[1];
  var base = itext.anchor[1];
  
  alert('Em? size: ' + (top-base));
