• Back to cache a sequence the old way. not in real time during the introduction of the cache

  Hi supports,

  I have problems of my sequences caching. As long the AE is always rendered images my reading is never in real time, it will be stutter audio until operations complete are cached. Makes me and my clients go nuts, so every time I want to playback of a composition, I manually turn off the audio, the cache of the sequence playing, which makes them note every time, "Oh a little slow" and "There is no sound" etc and I have to explain that his not playing not, just cached.

  I went back to the old way: Cache first before reading. The real-time playback + caching does not work...

  Also the 'working area of the Cache in the background "has disappeared... Why?

  And Im working on fast mac:

  CPU: 2 x 2.4 GHz Quad - Core Intel Xeon

  RAM: 48 GB 1066 MHz DDR3 ECC

  Boot SSD disk

  FusionIO Cachedisk

  My support is on a fiberstorrage Facilis (4K DPX real-time playback)

  If you have present clients, I totally recommend cache before play (like the old RAM Preview) option. Unfortunately, you can not have cache in the background (yet). I've linked the explanation in my response to your other post.

  Have you seen the preview videos or all the videos of NAB? The next version of AE wants to focus on the stability of playback, speed, etc. so it could get a little better. Acceleration using GPU for some effects (finally!) makes a big difference!

• Audio RAM not real-time preview

  I have an audio track in my project.  When I RAM show a preview of my computer, the sound is slower than real time.  When I double click on the audio file in the project Panel, a mini Player opens and reads the audio in real time.  Is there something I can do to get the sound to play real time for the RAM Preview?

  Well, it should play by all means in sync in real time. If it isn't, then soemthing is wrong. He plays in sync without applied effects?

• How to read the text from a DOS window in real time?

  I call an executable file that downloads a file to flash memory.  This program displays status information in real time as the percentage of completion in one window BACK.   It also makes account of the CRC of the file as it downloads.  I am currently redirect the output of the DOS window in a text log file.  This works fine for obtaining of the CRC when the file is actually downloading but the operator loses the visibility of the State in the percentage of download.  Is there a way to read text information in a DOS window with my request of LabWindows/CVI real-time?

  Hi Brent,

  If redirect you the output from the first application in a log file, you would be able to read the contents of the file streaming to your second request, and whenever the content changes (such as the download value percentage), couldn't display you this information immediately with the second request in one window DOS or some other GUI?

• Browse the contents of the hard disk of the target in real time

  Hello

  Is there an easy way to browse the content of the hard drive on a real-time target by using the file path control (or another type of control)?

  What I have in my application is a PC real-time desktop (running on PharLap) who has a Main.vi running on it. There are a few configuration files (for this VI) I want to be able to read and record to that would be stored on the hard drive of the target in real time. However, when the application runs and I hit the Browse button, it displays the contents of the Windows machine and not the machine in real time. Is there something I'm missing?

  Please note that I can send via FTP on the Windows computer to the target in real time and can interact with the drive of the target in real time without any problem.

  Thank you.

• How to read data from a worksheet to a chart in the form of wave at intervals to simulate real-time data

  Hi I have measured data using a SELF-DIAGNOSIS device and that you have downloaded the log files as a .csv I have attatched below.  I'm trying to read the 7th column of data (RPM) and display it on a waveform graph, read line-by-line to simulate driving real-time data. The interval between readings, I'm trying to achieve is 500 Ms because it is the time interval of readings on the worksheet. I'm finishing the two loops when rpm is equal to zero, as happens when the car is off. I have attatched the relevant section of my program below. Any suggestions would be greatly appreciated.

  Thank you

  Michael

  There are two errors in your block diagram.  First of all, as you read the entire table 2D in all at once (which is fine), you make a clumsy (pardon my language) job to make a line of programming.  Once you take the first line of headers, you have the ideal substrate for a loop, which is made of elements of an array (lines) process, one at a time, using its tunnel of indexation.

  The second mistake is to forget data flow.  The loop, I mentioned, or the While loop you use, produced one at a time and points it at 2 Hz thanks to your expectation of 500msec.  You want to give each point to your chart, but the picture is out of the loop, which means that there is No point until the loop ends.

  Here's an easy Question - where you put the indicators in table of waveform?  [Council - I said that "outside the loop is bad"].

• Read the contents of a cell in an Excel sheet

  Hello

  In an Excel file, I have several sheets in one leaves (for example: Dispersion) I have a cell that is located in column 3 and line 5, this cell contains a value (for example, 500). So since a VI, how can I read the contents of this cell pour out the value 500?

  If I only have a map I can USE the function 'Reading worksheet File.vi' Pour lire into a txt format file, but here I have an Excel file with multiple sheets in there, how can I read a cell in a spreadsheet says? Thank you for your lighting. Good week end to you all.

• Read a signal scope works in execution to highlight, but not in real time

  I want to get the maximum value of a waveform to a former stretch of Agilent 54622 via GPIB.

  The problem is that I regularly receive a Visa Read error-1073807339 ("timeout expired before the operation is completed") when running in real time, but NEVER in execution to highlight mode.

  The posts here suggests that the calendar can cause the read to run before writing was able to finish. So, I used one - manually controlled while loop, sequence and blocks waiting for try and ultra Structure separated blocks of reading and writing of overlap between them. But it still does not work!

  Suggestions, please? (Thanks!)

  

  If you happen to open the VI I attached, you will see that I use a serial port. This is because I use a USB of Prologix-GPIB adapter to interface with the scope (I don't have an adapter USB of NOR-GPIB). I used successfully this Prologix adapter for over 2 years to connect perfectly with an amplifier to locking SR830 and several other devices, so I don't think that's the problem...

• Leak memory in real time caused by VISA Read and timed loop of data nodes? Is not supposed.

  In collaboration with LV 8.2.1 in real time to develop applications that monitor or emulate computers on bus RS-422.   The following screenshots have been taken an application that monitors a transmission of 200 Hz.  After a few hours, the PXI station would break a range impressive messages angry... most involving something about memory loss.  After much hair pulling and passing money, my partner has discovered while looking at the available memory on the controller of loss of memory occurred at each loop containing a VISA read and propagation of error using the data nodes (see Leak.jpg of memory).  He concluded that if he went to the propagation of the error to the regular old shift registers, then the available memory was rock-solid.  (has the Leak.jpg of No memory)

  Any ideas of what could be the cause?  Do you see not any problem with the way that we code these kinds of loops?  We always strive to optimize the way in which we use the memory on our urgent requests and VISA readings and DAQmx bed give us the heartache more than ever, we are able to allocate memory for these screws some tips?

  Hi thisisnotadream,

  This problem has been reported, and you seem to be exactly reproduce the conditions required to see this problem. This was reported to R & D (# 134314) for further investigations. There are several possible solutions, of which one is the one you have already found the wiring error directly in the loop. Other situations which give rise to no memory leak are:

  1 if the bytes of the property node port is not there and has read lies in each iteration and time-outs resulting are ignored.

  2. If the structure of the deal is gone and just blindly check the bytes to the port and read each iteration.

  3. If the timed loop is transformed into a while loop.

  Thanks for the comments!

  Kind regards

• reading in real time - intensive filters

  Hello

  Today I made another transition. The one who is more intensive CPU and propably will not playback in real time.

  I read the guide I can communicate with the player (piSuites-> timelineFuncs.).

  What I tell him not to try to play in real time?

  What is the exact function of it? And how do I do this?

  Now if I try and play a work piece of my transition, playback stutters and continues to stutter even beyond this point.

  This isn't a really cool way to manage playback.

  So I was wondering what to do...

  See you soon,.

  Jaap

  Hi Jaap,

  Unless the reader plug-in is that you have developed, you will not be able to communicate with him to change reports in real time of your effect.  Your transition is automatically marked as not real time, with a red bar above segments that spans the transition in the timeline panel.  Playback in Premiere Pro plays at full speed, make the transition as quickly as possible, which may or may not be the image frequency maximum according to the required processing power and configuration of the system.  If you do not get a maximum frequency in the preview, and you need to see that, as a user, you can generate overview makes.

  Problems: The GUI is choppy, reading in real time is about 19FPS.

  Processes use about 3% CPU, 15% RAM, not anywhere near the bandwidth available for hard disks, etc.

  Suggestions?

  (Also, the search function seems to be broken on this site, so no, I'm not looking.)

  Thanks in advance for your help.

  Hey people, would like to report that we now have the real-time playback with the play of the space bar.

  I'm glad to hear you have AE to work a bit faster for you, but I have to tell you: one day this overview of the space bar will get bogged down, and if your people make a habit of using it instead of a good overview of RAM (zero on the numeric keypad), they will complain.

  Simply AE is NOT designed to read anything in real time.  He was never to play stuff in real time; That's what editing systems are for.

  Soon, someone will animate a half dozen or several layers of HD video using motion blur in a 3D, with 3 or 4 lamps model, and all layers are configured to accept lights and shadows.  They will hit the space bar and when AE reads an image, a second or two, they'll come after YOU, demanding to know what gives.

  It is really wise to get the habit of using RAM previews.  Extremely wise.  It is just as wise to forget the habit of hitting the space bar.

  On a different note, you might want to reconsider your processor and memory allocations.  Or at least tell your AE users that they may have to adjust depending on the circumstances.  Your current configuration might be dandy for a single layer without applied effects, but it is not the most beautiful thing in the world, if you have several layers of 8000 x 6000 in a model with animated each layer effects.

• CTI / read head plays is not in real time

  Whan, I'll see my animated film that I drag the CTI that my animation jumps rather than smooth running so I can see the animation.  It's like if I don't see a step at a time, including at - it a setting I need to change.

  Really, you must generate a RAM Preview to see your reading of the animation in real time.

  It is unlikely that you will see the results in real time by rubbing the CTI, unless you have an extremely powerful computer and a very simple and minimal project.

  Even in this case, it is probably still unlikely.

  Alternatively, you can set the mode of previw to Adaptive Resolution to help scrub perceived, but the resolution of the model will reduce the CPU trying to catch the movement through the timeline.

• Parameters DAQ update in real time

  I created a program to read the entry of similar channels and store the data in an Excel file. The program of work so far, however, the problem is, whenever I need to update the settings Assistant DAQ (sampling frequency and number of sample), I need to stop the program (by pressing 'STOP' Abort executing icon) and then enter the values you want, then run the program again.

  Sampling rate and number of sample are controlled by a digital input control. My question is, how would implement a update button 'real time' to set the new number of sample and the sampling frequency of data acquisition, while data acquisition is running?  As I am new to LabVIEW (experience 2 days), an explanation with an example VI would be useful.

  You can use the lower level DAQmx functions as in the many examples of shipping (help > find examples), but you cannot change these settings on the fly. You must stop the currently running task until you can change the sampling frequency.

• Get the frequency of a graph in real time of the waveform trace

  Hello

  I want to get the frequency of the graphics path in real time. The data comes from a connected to an Arduino UNO ADXL345. I use LINX to read data.

  I separated given x, y, z in order to plot separately and later to get their respective frequencies as well.

  Here is an excerpt of my VI as well as the front panel.

  

  I used a the Measurment file for each axes entry so I have a copy of the data.

  Before posting, I tried the LabView Spectral tutorial first. But it's different from what I want to happen because you know the exact frequency in this tutorial.

  I have also attached my VI.

  Thank you!

  If all you want is to know the spectral content of a signal in the time domain, there are a number of examples show how to do it. I would start by looking at the functions of the FFT.
