Real time counter?

• Count the number of times a letter appears in a string and the number of real-time display?

  Hello

  I need to count how many times a letter is contained inside a string that the user types in the text box (i.e., real-time) and display the counter on the page? I would really appreciate if someone can give me some advice how to do this in ActionScript 3.0/Flash CS6.

  Thank you very much in advance!

  A single element, you should not use is a listener for the CHANGE event of a textfield.  You will use as a trigger to check the text in the TextField.

  The details of how you check the text may depend in part on how the text is allowed to enter, but you essentially have to examine each character is entered and determine if it is the character you intend and if so, add it to t a sum.  You can use the String class charAt() method to get individual characters.

• Rotary decoder in real-time and 'pulse shifter '.

  Hello world

  I'm putting in place a rotating decoder for use as a shifter of pulsation by labview real-time.

  Basically, this means I have two input channels (ttl-legumes, ~ high 20us) rotary engine. A channel contains a pulse at each CA (angle cranc) ° up to 12 kHz (increment). The other channel contains a pulse every 720 ° CA (the charge cycle, BDC_cc low break-even point). With this information a pulse to be generated on an output also channel ttl (high), which triggers my setup of measurement. This impulse must be moved in a programmable relationship to the entrance of BDC_cc, which aims at a table of regular measure.

  I got it running by streaming the channel of BDC_cc until a rising edge is detected, then count the edges of increment to the designated trigger point and then generate a pulse on the output channel. The problem is that the late 70-120us exit trigger. In short it's too; a maximum error of ~ 20 is acceptable. Digital channels appear to work faster, so I put discarded Counter-based acquisition.

  I'm quite new to LabView, so I'm sorry if the answer is obvious...

  My purchase setup consists of:

  PCI-MIO-16-1

  BNC-2120

  LabView 12.0
  Max 5.3.1f0

  Widows XP

  This configuration seems to exclude some options Labview offer, such as the external digital acquisition sampled or externally triggered by the acquisition in the base. A manual interpretation of analog inputs is way to slow.

  I have attached my working version.

  Any input appreciated woud...

  John,

  I only have a minute right now, but think I can play with a device simulated tonight or tomorrow.

  I'm quite sure that there would be a clean solution clocked by material if you use a series M or X-series

  Council MIO, but the older generation counters timers on the set of the E series do support everything which

  You need.  It's been a while since I had to rely on this generation of hardware.

  I think the basic approach is to use the lunatics of angle as the clock pulse train that defines the

  delay time of the pulse you want to generate.   You could be "Timer" the pulse based on the real

  angular position, helping you synchronize to a specific angle of crank.  The question is whether and how E-series

  counters of takes to support the generation of pulses triggered (or redeclenchables).  If they are not, I would say that you consider

  get new hardware DAQ which support this kind of trigger and you give a very precise pulse

  implementation.

• Display in real time with a delayed recording LV6.1

  Hi, I need help with LabView 6.1

  I have a hardware module FieldPoint where I read 8 channels for thermocouple. I want to display the value of the thermocouples in real time (or as close as I can manage) all saving the values in a CSV file at discrete time intervals (every 10 seconds). I am able to display the values in real-time, but the recorder real-time records, produce a lot too much data. I'm able to delay the recording interval, but in bulk then display in real time!

  The following example shows a method I've tried. The delay time in the loop of logging seems to delay the entire program. I also tried to use the loop of the logging of a sequence (using a simple delay of 'Wait') structure and a structure of matter (with a counter and only do the loop of logging real when the counter gets to 1). I tried to configure synchronous display without success.

  I'm having no luck and wonder if someone could point me in the right direction?

  Ah, the benefits of time.

  I think that I managed to create a solution for me using a different tact. Instead of using individual meters of delay, I used a "trigger time" approach as demonstrated in this thread;

  http://forums.NI.com/NI/board/message?board.ID=170&message.ID=286988&query.ID=6280650#M286988

  Currently, it is limited because it will allow only a delay of 59 seconds between the readings, but this should be relatively easy to solve. The solution works continuously update the display with a slight delay to help cope aging computers, and then the button "Log Data" is selected writing worksheet function is called second pushed together as selected. Quite a simple and elegant solution I think.

• 9481 PWM in real-time

  Hello

  Currently, I am trying to control heater with a relay of 9481 operating module real-time on a cRio. According to some brochures NOR the 9481 a capacity PWM (not 100% sure of this). Is this true? How can I get access to the content of the PWM feature?

  I did it with the help of a compact data acquisition and output of counter, but not with the 9481 or a cRio (in scan mode).

  And if it is not possible, what would be a better route to go if I have to use the working 9481 one on a cRio?

  Thanks in advance!

  -TJ

  Hello TJ

  First of all, the NOR-9481 itself cannot produce the PWM, but it can run in cDAQ. Because the cDAQ chassis will end the PWM of the book part.

  Now that you use a cRIO, all labor PWM, you must complete your self (the 9481 cannot work as PWM in Scan mode), you must use the FPGA.

  There are some examples that you can find in the finder of the example

  

  Just write the digital output on the port of 9481

• Deployment of local variables shared on a real-time target

  Hello everyone, once again

  I read more posts and knowledge base articles about this topic than I can count at this point, and I'm scared, I'm still not clear on exactly how it works, and I hope that someone can delete it for me, if it is to earn themselves some laurels more.

  I have a project with a real-time quote and the other Windows.  They shared communication via network-published variables.  The real-time part also uses shared single process variables to communicate between the loops.  I have the intention of all 3 libraries of shared variables (Windows-> RT, RT-> Windows and RT Local) to be hosted on RT target for reliability.  Real-time executable must start at startup and run even if side Windows is not started (on the side of Windows is optional).

  I realized that real-time executable will not start the variable engine shared and/or deploy itself shared variables.  I also read that I can't deploy the shared variables programmatically from the side of RT.  This leaves only two options that I know of:

  (1) their deployment programmatically in Windows-side program.

  (2) deploying the shared variables on the target RT manually via the project in the LabVIEW development environment, and

  About option 1, as I said running Windows is supposed to be optional, so you have to run a program on the Windows side before the side RT will work is highly undesirable.  Moreover, even if I do a little "Deploy shared variable" application that runs at Windows startup, I can't guarantee that it will work before start of the side RT executable will run.  In this case, the executable file RT will fail due to not having the variable engine shared running?  If so, and side Windows, and then starts the engine / deploys the shared variables, the side RT begins to work automatically?  If not, is it possible to trigger this restart of the Windows startup application side?

  Also, I just read everything and tried the option to build to deploy variables shared in the application of the side Windows.  Not only that my RT shared Local Library variables not listed as an option (given that the application of the side Windows does refer to it in all for obvious reasons), but when it deployed two other libraries at startup, the program side of RT (which was running in the development environment) stopped.  I'm not positive that would happen even if he was running like a real executable file, but it is certainly enough to make me nervous.  I assumed that the library is not listed may be resolved by including a variable network-a published in the local library of RT and including the app side Windows.

  About option 2, I don't understand how I'm supposed to deploy my libraries shared variables without stopping the execution of the startup on the target real-time application.  Once I did, the only way to restart the application of the RT is to restart the computer RT, correct?  In this case, I just undid all the interest to deploy the shared variable libraries?  Unless libraries remain deployed and variable motor shared running even after restarting the computer of RT, which would solve the problem I guess.  Certainly, I would like to know if this is the case.

  However, option 2 is complicated by the fact that when I manually right-click on any of my shared variables libraries and select "Deploy" or 'Deploy all', libraries still do not appear in the Manager of the distributed systems, even after clicking Refresh several times, on the local system or the target system.  The only thing that shows up, on both sides, is the Group of 'System', with FieldPoint, etc. in it.  The same is true when I run my application in real-time in the development environment, even if the shared variables are clearly working, as I mentioned earlier.

  So, if you have done so far through this mammoth post, thanks!  I have three main questions:

  (1) are that all my descriptions above correct in what concerns the variables how work sharing?

  (2) what is the best way to meet the requirements I have described above for my project?

  (3) why shared variables libraries not appearing in my manager of distributed systems?

  Thanks for any help you can give on any of these three questions!

  -Joe

  1. Yes, as soon as you deploy the project the NSV is tranactional.  EVS is loaded by MAX when you configure the RT target and begin to operate as part of the boot sequence.

  2. you can see anything on your target rt in the DSM?

  3. Yes, NSV and EVS are persistent resets.

• change the properties in real time

  Is this possible?

  I have a digital command and a loop for. I would like to change the propertis of num control so that it increments as the Terminal counter, i.e. control number is a multiple of the meter. The user can run the loop for x times those and another times y times. Digital control are editable as it is a multiple of the value?

  Thank you.

  Yes, you can change these properties at run time (real-time is something different).

  Right-click on the control terminal, select Create-> property-> data-> incremententry limits.

  Good luck.

• Display in real time

  Hi guys,.
  I try to get the time on the server in real time and I can't count the seconds in real time,
  I am able to get the time of CFM to Flash, but if I loop the frame in order to get the real time as seconds, my page takes forever to load. Can someone please tell me what I'm doing wrong?
  What is the best way to get the servertime and make Flash to show the seconds count in real time. Like this , but get the time of CFM.
  
  
  Here are my codes:
  In ft3/min:
  < cfset todayDate = Now() >
  < cfoutput > & servertime = #TimeFormat (todayDate, "h:mm:ss tt") # < / cfoutput >
  
  In Flash, frame a (1):
  loadVariablesNum ("showTime.cfm", 0);
  this.onEnterFrame = function() {}
  ServerTime = eval ("servertime");
  MyTime = unescape ("the server time is:" + servertime).
  };
  
  In the frame tree (3):
  gotoAndPlay (1);
  
  Thanks in advance.

  OK... function of the precision you need, how about this...

  Why not get the date and time say every 60 seconds using setInterval as your timer

  something like that

  Call getdate to get the initial datetime value
  GETDATE()

  function getdate()
  {
  erase programmable intervals
  clearInterval (mynewdate)

  get and display your date
  loadVariablesNum ("showTime.cfm", 0);
  ServerTime = eval ("servertime");
  MyTime = unescape ("the server time is:" + servertime).

  call this function in 60 seconds
  mynewdate = setInterval(getdate,60000)
  }

  You don't need your loop then and can then change the date display to show 10:45 without seconds.
  If you want it seconds then reduce 60000 to 1000, but I don't think that Flash will be able to deal, as if loading takes more than one second maynever get round to display text?

  hope this helps

• Get strange errors 'real time' in the browser console, what do mean?

  I noticed recently that since yesterday is the day prior to that, I get a strange 'real-time' error messages in my browser console log. I get them for more or less the same sites, and I have attached a screenshot of some of the most common mistakes for example. I see these errors very frequently in the browser console log.

  Hello everyone.

  This is my first time on the site.
  I have a Satellite Pro C650. I have had it for 3 years now & everything is going well except the real time.
  Real time shows dozens of yellow folders that contain content zero. As I remove them one by one, they disappear, but the program stops during the removal. Then they reappear next startup.
  I am running version 1.6.06.32.

  Any help would be great.

• Satellite Pro M30 - real time clock shows wrong time

  Hello!

  most of the time I am using my Toshiba satellite pro m30 without the battery with the energy of the power system. the battery is stored somewhere outside of the computer for a month the real time clock shows a bad time if the computer is started after a period of time.

  I think my cmos battery is going to die soon.

  someone has an idea, how this cmos battery can be changed by myself?

  Thank you
  Reinhard

  Hello Reinhard

  I agree with you. It is time to replace the CMOS battery. It is not easy and the machine must be dismantled. If you are not familiar with the procedure for disassembly, it can be dangerous. A small mistake can result with damaging material.

  If you want to do it alone, you do so at your own risk. Be sure to use the right battery. Maybe you won't believe, but if you use a battery hurt it could cause battery explosion, or other damage.

  I'm not 100% sure, but the RTC battery must be placed on the left side near the touch pad. If you want to only please be very gently. The laptop parts are very sensitive.

  Hello!

  Unfortunately, this feature is only available with the GoPro cameras.

  And Yes, if all cables already existing for these purposes, it would be kind of a pain to take pictures and do not shake the camera accidentally. Maybe, VSCO camera makers will make such feature in some time in the future. This idea is excellent and innovative. Maybe even Apple will listen to users and make their new iOS 10.
