• "binding" layers for a rotation over time...

  Hello world

  OK, I hope a good question I will ask here...

  I have a picture frame and a few videos of my son. and a title that I want to appear on the photo frame.

  Picture frame represents a simple graphic in the .png format.

  The video is simply simple video I shot with my video camera.

  I have the video on layer 1 and the image above it on layer 2 and layer 3 I have a title 'Happy Birthday '.

  Now I want to rotate the frame of the photo (and the title Happy Birthday) a little at precise moments in time... online but this now shows a problem.

  How to rotate both the title of 'Happy Birthday', image, AND video at the same time? ... is it possible?

  Of course, I could manually dupicate keyframes, but I wonder if there is a way I can do this, with some kind of process, liaison

  Maybe I'm just not lucky.

  Thanks for your colleagues in time!

  Dave.

  Select the image and video, right click and nest.

  Now, rotate on this new "clip", called nested sequence.

  If you double-click on this 'clip', it will take you to both clips in a separate calendar.

• Want a ramp of output voltage over time and measure input 2 analog USB-6008

  Hello

  I want to produce an analog voltage output signal that increases over time with a certain slope, which I'll send in a potentiostat and at the same time I want to read voltage and current (both are represented by a voltage signal) that I want to open a session and ultimately draw from each other. To do this, I have a DAQ USB-6008 system at my disposal.

  Creation of the analogue output with a linear ramp signal I was possible using a while loop and a delay time (see attachment). Important here is that I can put the slope of the linear ramp (for example, 10mV/s) and size level to make a smooth inclement. However when I want to measure an analog input signal he's going poorly.

  To reduce noise from the influences I want for example to measure 10 values for example within 0.1 second and he averaged (this gives reading should be equal or faster then the wrong caused by the slope and the linear ramp step size.) Example: a slope of 10 mV/s is set with a 10 step size. Each 0.1 s analog output signal amounts to 1 mV. Then I want to read the analog input in this 0.1 s 10 values)

  Because I use a timer to create the linear ramp and the analog input is in the same loop, the delay time also affects the analog input and I get an error every time. Separately, in different VI-programs (analog input and output) they work fine but not combined. I searched this forum to find a way to create the ramp in a different way, but because I'm not an experienced labview user I can't find another way.

  To book it now a bit more complicated I said I want to measure 2 input analog (one for the voltage of the potentiostat) signals and one for the current (also represented by a voltage signal) and they should be measured more quickly then the bad of the analog signal. I have not yet started with because I couldn't read on channel work.

  I hope someone can help me with this problem

• Plotting the amplitude of a spectral peak over time

  Hello

  I am creating a VI where the acquired continuously DAQ, plots and save a waveform in millisecond delay (which is already done in this case), then takes this waveform, finds a specific pic (probably the first) and trace the amplitude of this pic over time (+ 30 minutes, one point each scan which is obtained). Essentially, I have a detector quickly attached to a chromatograph, and I want to select a single ion and monitor the amplitude of this ion. I can draw the waveforms along with it in post processing, but I want to do is to have the 'slow' constantly plot to update and display when it moves through time. Joined the VI will go in, using IMS software V1.3.vi, the paragraph is the "GC" Mode it seems I should use the "peak detect.vi.", but I'm not familiar with this operation, and so I don't know how to show a constantly updated graphic or remove the amplitudes and draw. Thank you for your help,

  I get an amplitude on plot of time, but it does not appear until after all the iterations are stopped

  I have not watched your VI (because I'm in a previous version of LabVIEW), but it's probably because your graphic is outside the loop.

  Here's how you can get a graph of the peaks (all vertices, by iteration):

  

  Or if you want to only a certain PEAK (and how this pic changes with the number of iterations):

  This is not a formula, but a constant simple schema of a table complex. Wire remains, then do a right click of the terminal of the initializer of the feedback node and select "create constant. That should do it.

• full waveform graph to calculate the area under the curve over time

  Hello

  If please find my attached VI and help me please for integration to get area undercut for my chart of waveform.

  I would like to find my wave power wind energy production chart oever within one month of time.

  I think I have to integrate to get the area under the curve and so I m now using tool integrated into labview attached.

  As I did not wait years for my result and so I want to make sure that the tool that I m using is correct.

  Please advise me what method I will use for my chart.

  Dominique says:

  I would like to integrate my table of power over time (table of power is on each interval of a minute) and the entire graph is one month. So, I'll put dt = 1?

  You put dt at some units you want in the final result. If you want Wh, you want dt in hours. If the spacing is currently a minute, you can express in fractional hours and use the result as dt. Try dt = 1/60.

• Get information from change of color over time

  Hi all

  I am new to LabView and on this forum, so I hope I'm in the right subforum. If this isn't the case, it would be nice if a mod could move this thread.

  My problem is the following:

  Let's say I have a white spot I want to observe with a camera. The color of the spot turns green over time and I want to acquire the photo, as well as to get the color intensity of green increase developing countries over time. I do not know what features I need to use to get there. Can someone me hint in the right direction? I think that it is at least possible in LabView.

  Thank your all for your help.

  Best regards

  I don't know what the best resource for IMAQdx pilots, I think that the examples that provide OR are pretty useful. Here's a simple VI which will tell you the average value of green of all the pixels in your image.

  

• Laptop HP G62-451SA: cannot read the label for Office 2010 product key as it dissipated over time

  Obliged to restore settings after a total crash.

  Spent the whole day as recommended by HP, including using my recovery disk that has failed.

  Tried to open Microsoft Office 2010 as usual, but said to give the product key to activate it.  Mine is on a sticker on the bottom of my laptop.  Unfortunately it is place to be where it is that some of the numbers have disappeared over time.  Now I can read only the last 15 digits.

  Ages worn on Microsoft support pages and basically they said that the onus to solve this problem since I legally paid for it when buying their product to HP.

  I'll lose more than a year of work, if I can't get this sort.

  Thank you.

  The label on the bottom of your laptop is not for the office. It's your Windows license key. It should say Windows 7 Home Premium above the numbers.

  Most of the HP machines come with a trial of office unless order you it with more full Office and pay extra. The trial usually actually works after the period 60 day trial - unless you do a recovery. After a recovery it will require you to buy a license key to use.

• Advice on the restructuring of code to avoid the downturn over time

  Hi, I am a new user of LabView, you want some advice on how to better structure the program I wrote and which is used to perform a hydrostatic test arrangement. Data are collected on a module of AI cDAQ 9207 and a cDAQ 9474 module is used to control the two valves that subsequently controls pressure in and out of the test Chamber. I enclose my first version of the reference code.

  What the VI is supposed to do when the user of the weapon system and strikes then the execution, the program switch will cause a transition of the test chamber through several States corresponding to the levels of different pressure for some time. Time curve vs pressure is written to a file of measures. I built using a state machine structure.

  My problem is, during the initial trial, when the duration of the test was about 5 minutes or so, the program went very well. However, once I started to test the length of the actual test of 2.5 hours, I noticed the program running slower and slower as time progressed to the point where it would take several seconds for each iteration of the loop, then by accident about an hour or two in the test. After scouring the articles and messages, I suspect the main culprit is the diagram of waveform and to a lesser extent DAQ assistant.

  While I need the loop structure data collection and case to run pretty quickly (preferably the order a few hundred s/s) I need the code to be able to react to changes in pressure in the room quickly enough, the actual data, that I need to store and display the graph can be as slow as a sample per second or even longer. My guess is at this point that I have to rebuild the program using some sort of architecture of producer/consumer, I'm looking for some advice on how best to structure the program.

  Data acquisition obviously belongs in the producer loop that will run at a fast enough pace and there will be a consumer loop that will run at a much slower pace for the Bulletin Board writing to the extent of the file vi, but where should I put the case of structure state machine which currently controls the valves? Should put in the loop of the producer since it must run at the same fast pace as the collection of data, so it can react to changes in pressure or should I build another loop of consumer for him? What other indicators (pressure and Boolean) and controls on the front panel, they should be on another loop operating at a medium speed I want to respond to a faster pace than the data to the chart/write the loop, but they do not need to be as fast as the data acquisition loop?

  Finally, I'm not quite sure what would be the best way to reduce the sampling rate of the data that I have in fact appear on the graph and the store in the file, it wouldn't make sense to create another task of measurement that samples at a rate below just for that purpose. Suggestions and advice would be greatly appreciated! Thanks in advance!

  My guess is that if you monitor the use of memory over time, you see that going up, Yes? Everything is is always a good idea to get rid of the express VIs, I would look for the problem of slowdown in the structure of the case. You repeatedly open and never close tasks which are created using some DIO channels. Hnece each time that the loop more memory is allocated. Try to move creating channel screws out of the loop, then the tasks are created once before the start of the loop and then written to as required inside the loop - and don't forget to delete tasks once the loop over.

  Mike...

  PS: You are right with your comments regarding the structure of the producer consumer. Basically it break up as things get quickly (DAQ IO) that there is in a loop, while the user interface and the stuff that can take a long time (such as the data record) are in another loop. You can even have three loops with one for the acquisition of input data and the other for the digital output.

  PPS: Finally don't forget that even if the structure of consumption of the producer is usually represented with everything in a single diagram, there no need to be. I wrote a lot where each loop is in his own VI which is run dynamically, then the application starts.

• I2C communication slows down over time using USB-8451

  Hi all!

  I try to communicate via a device slave using a USB-8451 I2C and I noticed that after a while the communication speed slows way.

  I can send and receive data very well and apparently my system seems to work. But the problem is that over time the speed of data transfer slows down so much so that if I let it run all night it has slowed to a crawl in the morning. My ultimate goal is to gather data, draw and save every second and at the beginning it is easily achievable, but after 10-15 hours I can no longer collect data as fast I need. I'm not quite sure if this is a problem with my code LabVIEW, the NI USB-8451 box or the slave device. But if I stop running the LabVIEW program and start it again, everything returns to normal.

  The slave device is a personalized card with a microchip PIC which acts as a slave I2C and returns the data at the request of the master. I can't imagine anyone will be able to determine if this is a problem directly, but if we can rule out the other two (code LabVIEW or the NOR-8451) as the source of the problem so I know it's my slave device.

  I've greatly simplified the LabVIEW code that I used to collect data on I2C and I see even this gradual slowing down over time. Attached, it's that the very simplified VI and the data file, it produced. I only ran it for about 45 minutes, but from the beginning to the end we see again that the enforcement timeframe is rising.

  I hope I'm just doing something stupid, thanks in advance!

  -Aaron

  Aaron,

  Do not have the additional module responsible for these functions, but I'm sure I know whats going on.  It seems that each time through the loop 'OR-845 x I2C Create Configuration Reference.vi' creates a new reference.  After a while it will start to slow things down.  Better to open the reference before the while loop starts and spend just the reference in the loop.  Don't forget to close the reference after the loop stops.

• create the voltage over time

  Is it possible to generate an output voltage on a DAQ 6009 A0? I have a data excel sheet that I put in a 2D array. The voltage is not constant over time. I have problems with the synchronization of the signal. I was able to trace the signal on a chart. This is the same as the original data to excel. I have two data streams. Voltage and time. But after separating the two signals how can I generate the graph?

  
  

• My WRT110 slows down gradually over time. Why?

  I noticed that my internet download speed became slow.  I tried using SpeakEasy and the speed of Comcast tested and found my upload and download speeds to be both less than 2 MB.  In the tests, I disconnected my WRT110 RangePlus Wireless Router and connected directly to the Comcast RCA modem.  I raised the speed races and got 21MB down and 4.4 upwards on two speed test sites.  I then be able to reset the WRT110 then reconnected to it.  So I ran the tests of speed and their return the same 21Mo down and 4.4 upward.  I came home a day later and tested and my download speed is 8 MB.  I came back today and it was 5MB.  I connected directly to the modem Comcast and returned to 22 MB down speed.  I then be able to reset the WRT110 and reconnected it and speeds were down to 22MB.  I have run this test twice over a period of days and got the same defacement of speed over time.  What could cause this?

  I think you can try to upgrade/re-flash the firmware on your router.

  Connect the computer to the router with the Ethernet cable. Download the latest firmware from the site Web of Linksys. Open the router configuration page and update the firmware on your router.

  After upgrading the firmware of your router, it is recommended that you must reset the router and reconfigure. Press and hold the reset button on the router for 30 seconds. Release the reset button and wait 30 seconds. Power cycle the router and reconfigure.
