• Find the difference of pressure between the two transducers using a NI DAQ 6008

  Hello

  First of all, I'm a relatively inexperienced LabVIEW Developer, so my apologies in advance if this message does not have something, or otherwise lacks clarity.

  I try to develop a VI as follows the pressure difference between the 2 EME 3100 pressure sensors (4-20 my), related to two different pressure lines, using a NO-DAQ 6008. I would like for the acquisition of data to read the two transducers, then have him find VI the differential and write this differential in an Excel file.

  The data sheet for these sensors may be found at: http://www.gemssensors.com/Products/Pressure/Pressure-Tranducers/Sputtered-thin-film/~/media/GemsNA/...  It is a 3-wire system, with a voltage between 8 - 24V. I use an external power supply of generic brand to power sensors, which provides a maximum of 24V @ 4A.

  I drifted my physical connection (for the two transducers) this thread http://forums.ni.com/t5/LabVIEW/I-am-having-trouble-Omega-PX4200-Pressure-Transducers-to-where-I/m-p... and am relatively certain of the accuracy of the information. For purposes of signal conditioning, I use a 500 Ohm resistor between the signal of each transducer and the Earth wire.  On the side of software, I use the latest version of LabVIEW (2011) as well as MAX on a Windows 7 64-bit machine.

  In an ideal world, the sampling rate would be as high as possible, but 4 samples per second would suffice for all purposes useful.

  Given this goal, are there any sample of VI (especially for MAX, which I have not yet used) who would be similar/applicable to this project, specifically, regarding setting a sampling frequency, calibration of the transducers or affecting the pins/channels appropriate? All resources would be greatly appreciated.

  Kind regards

  Measure the voltage between the two resistance (resistance by probe 4-20 MA) using the differential inputs of the x 600.

  When you configure the task, you can read several entries at once, by entering in "Dev_ / AI0:1" in the physical channels and using the "several channels / {unique |}". multiple} samples"polymorphic instance.

  600 x can read 1kS/sec.

  Do maths/conversions on the table, and then simply subtract the two tables.

  Could also take some samples (10-100) at 1 kHz and their average together, give you a smaller rate effective sampling but with less noise.

  A loop of producer-consumer would be good architecture here, let the daqmx reading live in a loop and sends the data via a queue to a 2nd consumer that performs mathematical operations and write to a file.

  

• I can't stop finite samples daqmx read between the two?

  Hi all

  I want to read data from 10 seconds to a trigger is received. for this im using daqmx task finished sample mode and read the data on the trigger getting. It works fine but I can't stop my vi between the two when its reading of the data. I have to wait for it to complete the reading of values, and then stop the vi.

  so I switched to continuous sampling mode that allowed me to stop the vi whenever I want.

  I just want to know is there any means or the property using which I can stop my task over daqmx read when I want?

  I guess you call DAQmx Read with extraordinary value (-1) for samples of #.  It is also the default if left thread continues.  In a finished sample task, it means to wait until the memory full buffer has been filled with samples before returning.  Once you make that call, you cannot directly finish soon.  You're stuck waiting for buffer fill or for the timeout expires (default 10 seconds).

  One way to avoid getting stuck is not to ask for samples that do not exist already.  You can query a DAQmx Read property, known as the "Samples available" or something like that and son of this result in a call to DAQmx Read.  Such a call will return immediately whatever data are currently available.  Subsequent calls will give you samples.

• I have CC installed on PC can I use creative cloud on the iPad Pro with a smooth transition between the two?

  Hey - I hope you can help. I'm under CC on a PC and I buy an iPad pro. Can I perfectly send/receive the vectors/graph between the two devices - in other words is going to talk about Apple and Microsoft to another. So if I'm with a client and then come home can I download/send what I did on my ipad and continue to work on my PC?

  Sorry to sound stupid, but I can't seem to find real answers anywhere.

  Thank you!

  Hi Vicki,

  You can use Adobe Creative Cloud on your desktop (PC Win) and also on your device (iPad pro).

  Just be sure that PC supports the desktop versions of the apps (desktop applications Adobe Creative Cloud|) Adobe Creative Cloud ) and the iPad device will support mobile applications (Mobile Apps ).

  You can synchronize the work on one of the applications to the course in the library of creative cloud in order to adapt them to another application.

  Hope that helps!

  Kind regards

• Switch between the two alternative provisions (both in portrait mode)

  I have created two alternative facilities for the purpose of these two being in portrait orientation, as they are to view the same article in two different languages. Is there a way to switch between the two using the navto: / / action or by using bookmarks and by using the go to destination. I tried both but I was wondering if there was something there.

  I have a publication ideally appearing in both languages, though being a main language and the seconary being there only for reference. I'm not wanting to produce two folios and use the filter region with Apple, as have the secondary language, as a reference is a selling point for the publication. Also using"States" would be more complicated.

  He must choose between non-ideal solutions, as a magical sticky toggle 'use this language' is not available.

  If you do mind ' t using the rocker on each page, then navto would be OK. and each page of the reference language should have a back button go. All reference pages that can be marketed after the main pages, and each of them can be hidden from OCD.

  If you opt for parity between languages, then you could start the app with no menu-swipable selection page, where you can decide what language to use. At the end of these two sections, another non-swipable page would give you the choice to read another language. The trick of no-swipable page gives users a feeling of an application of the only language of his choice.

  And I would use diapers, not another layout for the production. Seems to be a cleaner solution for me.

• The merger between the two images with the control points? Novice request

  Hi all

  I've seen a tutorial that describes exactly what I want to achieve, but can't for the life of me remember of it called or how to do it.

  Basically, I have two images of the map I want to put in a short film. During the transition between the images, instead of simply melted into a single image I want that they "sink" in the following image.

  The tutorial I've seen used Premiere Pro and "checkpoints" that match between the two images showing where things moved too.

  I am barking the wrong tree? I will reply cheerfully questions in an attempt to better describe this. I apologize for the vagueness of the topic.

• Trying to get the 'difference' between the two tracks

  What I'm trying to accomplish is the following: I have an audio track of a voice-over with a music bed located underneath. I also itsself Chamber music, without the voiceover. I want only the share of voice. Is it possible that I can "cancel out" the part of the music or get the difference between the two tracks (just the voice part)? It seems that there should be a way to do it, but for the life of me I can't figure out how do it!

  Any advice?

• The difference between the two copies and Clone?

  I make a copy of an existing symbol. On the Edit menu, they have Dulicate and Clone to achieve this. What is the difference between the two? As far as I can tell, if I select the clone, it puts a copy of the object directly on top of the selected object to copy. If I select duplicate it offered the copy is not directly above the original to copy object. What is the difference?

  Well Yes

• Switch between the two button symbols

  Hello

  I'm new to AS, but not new to programming.  I'm using Flash CS4.  Here's what I'm trying to do.

  I have two button symbols, PlayBTN and PauseBTN. They are used to control the playback of the slideshow. When I use one or the other to control the slide show, it works. However, what I want to do is to switch between the two buttons, so that they work together like this:

  1. If the slide show is playing, PauseBTN is visible. If PauseBTN is clicked, stops slideshow and PlayBTN becomes visible.

  2. If the slideshow is paused, PlayBTN is visible. If PlayBTN is clicked, stops slideshow and PauseBTN becomes visible.

  In other words, clicking on the button control not only the slideshow, but changes which button is visible.

  I got this working with a video clip of two frames and bitmaps in static, but when I swap the bitmaps for the buttons, rollovers button stop working.

  Can someone give me some advice please?

  ... Mike

  This is not a flexible configuration.  PauseBtn should be a movieclip with a up more and eventually to the bottom of chassis and PlayBtn either a movieclip with a up more and eventually to the bottom of the frame.  You can then use:

  PauseBtn._visible = true;  or false ot visible property of your control button.

• How to specify the spacing between the two components

  Can specify us the distance between two points on a form? If so, please let us know how?
  
  Published by: user1670125 on July 14, 2010 05:37

  Hello user1670125 (please tell us your name).

  It depends on if you mean vertical (distance between the items on separate lines) or horizontal (distance between the items on the same line).

  A method I use for opening a vertical space between two elements is:

  -establish a single display without label
  -Name it "P #_BLANK ' or ' P #_BLANKn ' (if there is more than one page)
  -give a sequence so that it renders between the two points
  -do not escape special characters
  -give a source value of "< br / > < br / > < br / >" (according to the number of blank lines you need)

  A method I use for opening space horizontally between two elements (assumption here, is that you have defined the second element to not display on a new line and have adjusted the scope of column on other points in the same region to bring together the two fields as needed) - simply specify "& nbsp;" & nbsp; & nbsp; "in the first element display text of item (according to the number of spaces you need to).

  Hope this helps,
  John

• How can I measure the time between the two edges of successive increase, using digital input...

  Hello

  I'm trying to measure the time in seconds between each two successive rising edges on a digital input.

  So far I managed to detect the rising edge, increment a counter at each rising edge and take the time during which the increase is edge

  all I need now is subtract edge currently rising from the previous era of edge rising to calculate (T), which can be 1/frequency and display in real time for the user.

  but I do not know how to do this

  Can someone help me please!

  Note: while I am in a position varies between 200 ms - 2 seconds

  
  

• Not sure of the difference between the two registry paths.

  HKEY_LOCAL_MACHINE tools\msconfig\startupreg\

  entries are stored here, program under key and others, how are they different from the entries stored here...
  HKEY_LOCAL_MACHINE tools\startupreg\
  They two have something to do with starting. someone with a little know-how in this field could be a great help.
  What is the difference between these two and what not the keys of each way folder. ?

  If it is any help, I checked my xp, vista, and win7 and they all have this branch of the registry but it is empty of all keys. for example empty:

  HKEY_LOCAL_MACHINE tools\msconfig\startupreg\

  and none of the bones had the other key that you mentioned. I do not use quicktime, so this may be the reason why.

  If I had to guess with analysis and fiddling with the registry since it was invented by microsoft, registry branch I have is 'standard '.

  While the secondary registry branch that I don't have is "non-standard" and probably created by quicktime or other software during installation.

  These registry branches are created because the manufacturers software third differring depend on utilities such as quicktime will be writtened to find the key in the registration or another branch.  If the additional branch and keys are added for extra measure by quicktime or other programs.

  I think that in your particular case, only quicktime can tell you why they need to put their keys in 2 different branches.  but its likely that my logic above explain the reason for being.

  HTH.
