• How .vi DAQmx Read (analog 2D NChan DBL NSamp) to acquire continuous data?

  I try to get the .vi DAQmx Read (analog 2D NChan DBL NSamp) to acquire data continuously.  The 'help' indicates I need to wire the number of samples per channel-1, but it doesn't seem to work for my application.  If I have the wiring to any number greater than 0, the data collection works, but is not continuous.  I enclose the code (Sept15_MainPanel_WorkingBaselines_ApplyBaselines and Calibration.vi) and a Subvi (Collect_Baselines.vi) if someone wants to take a look.

  Here's what I'm trying to do:

  I use a unit NI USB-6009 to collect analog voltages of load cells 2 (channel 0 and channel 1) and 2 displacement transducers (channel 2 and 3).  The main panel of the VI contains a listbox with 4 options - 'Check EMG channel', "Collect base lines," "Collect Data" and "end of program".  'Collect base lines' 'End of program' work and I'm working on writing code to "Collect data".

  For the option "Basic collection", 2500 samples are read from 4 channels described above and 2500 samples are averaged.  This works.

  The option "Data collection" - I would like to that data from 4 channels to acquire permanently.  Finally, for the option of data collection, data acquisition stops when channel 0 detects the force of 200 N - so I will not always have a finite number of samples read.  The time it takes to reach the value of this force will be different for each test.

  -How can I get continuous samples for my 4 channel?  Is .vi DAQmx Read (analog 2D NChan DBL NSamp) function badly and if yes, what should I use?

  Thanks in advance for any ideas or advice.

  First, in case 1, you need not the structure of flat sequence.  The son of the error and data properly will dictate the flow of execution.  Then, in State 2, you must initialize the shift register, unless you want to keep the data is accumulated each time that you run the vi.  The reason why you don't see all the data here is because you have - 1 wired for the number of samples per input channel.  You must connect a number here, even if you are taking continuous samples.  The service needs to know how much sample to gather at one time.  If you put-1 here, the number of samples per channel must be set up in the synchronization function DAQmx (sample clock).  If you specify a number here, then you put-1 in playback function.  The DAQ hardware will read continuously, you must retrieve the data from time to time, so you must specify the number of samples.  By reading inside a loop, it will continue to read until the stop function is encountered.  I guess that the Clear function acts as a stop.  But you must always indicate playback vi how many samples to read and return on each iteration of the loop.

  The documentation is a little misleading.  He warns that a - 1 will cause a continuous reading.  But the pads are so big, he can not read continuously forever without losing data.  If you specify a finite number, playback in a loop, and he will read this number and return the data (empty the internal buffer) at each iteration of the loop.  Continuous means that you just call the start function once.  He will read at each iteration of the loop until the stop function (or clear) is called.

  Here is the difference between the setting of the Timing DAQmx function for continuous or finished reading: finite samples requires a tenure, he reads the finite number of samples, and it's done.  It requires another start to read more data.  Continues to read requires only a start.  It still reads a finite number of samples, but when this is done, you can retrieve the data by calling the read function until he could continue.  After the reading, you don't have to call for new start.  Look at it this way.  Start is what starts the collection of data, not the read function.  Just read empty buffers in your data feed.  The data acquisition continues in continuous mode, but you must call read again to get the data on the pads.  If you specify basically buffer size when you set the number of samples per channel.

• acceleration of displacement

  Hello

  I have an acceleration signal

  I can integrate twice using Labview VI as indicated in the attached file in order to find the signals of speed and movement.

  But how to calculate the INITIALS CONDITIONS of speed and displacement?

  And how to include these initial conditions in VI

• 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.

  

• When running the defragmentation, showing a bar with files which is displaced

  While you run Disk Defragmenter to botom of window bar indicates progress and moved the files. I looked at the names of files that is displaced, and some are very strange. Recently a few names were similar.  names cannot be exactly as show, but very similar. Really not sure if this may indicate any adware or spyware.

  You can see the files in your browser cache internet or other temporary files.  For best results, you need to "clean" your as much as possible before you run Disk Defragmenter.

  You can use the built-in Disk Cleanup tool (start > run > cleanmgr > OK) or an application such as Ccleaner or ATF-Cleaner.  With any of these cleaning products, including the built-in Disk Cleanup tool, you will need to exercise judgment a little in what you remove.  Do not use the 'Register' tool that comes with Ccleaner.  Do not delete the files 'Prefetch' offered by ATF-Cleaner.

  You can delete your temporary Internet (aka browser cache) files directly from the browser.  For IE, start by clicking Tools > Internet Options.  Where to go from there depends on what version of Internet Explorer you have.  For Firefox, Options > advanced > network > clear now (under storage offline)

  If you have multiple user accounts, log on to each of them and use the disk cleaner of your choice.

   

• Problem with the displacement map

  Hi all

  I have problem when using a displacement map. Basically, I followed all the steps (Desaturate the background image, slight fuzziness, copy/paste on the new doc, save it as displacement.psd on the desktop).

  And the problem is that whenever I have download the displacement on the image file and no matter what numbers I enter ladders vertical and horizontal, the only thing it does is to move slightly to the left upwards. There is no deformation applied of any kind on the image. I have this same problem with any image that I try to apply the displacement.

  Can someone help and explain what could be the problem?

  I can't reproduce this. The layer as you try to duplicate a smart object and there a displacement map? Looks like you might need to reset your preferences.

• I have a problem of my catalogs of PES 10 displacement and the photos attached from my old computer with Windows XP on my new computer with Windows 10.  The problem is that I can't remember the arrangement of the original tree of my photo folders when I r

  I have a problem of my catalogs of PES 10 displacement and the photos attached from my old computer with Windows XP on my new computer with Windows 10.  How can I keep my original photo folders tree arrangement when I restore backups of catalog on the new machine?

  The problem arises because Windows 10 is equipped with a new tree structure with new names for many of its branches.  Tree of Windows XP starts to Local Disk (C), and then does the following: Documents and settings, Susan [it's me the user], My Documents, SusanPhotos (the folder that I created that contains my photos) and then several subfolders and subfolders with my photos grouped by theme, for example the Puglia Italy and Italy-Roma.  My new computer Windows 10 has a different tree and different names for a large number of branches from early on: OS (C) [instead of Local Disk (C)], users, Susan, Documents [instead of the old My Documents], SusanPhotos [what I created] and then the subfolders and so on.

  Because of the new tree and the new names of the branch, I can't find a way to restore my PES 10 catalogues and photos attached to them to where I want to that they.  What I want to do is put the files from SusanPhotos to the Windows 10 Documents folder so that I find myself with the following tree, essentially the same as what I had on my old machine: OS (C), users, Documents, Susan, SusanPhotos, then the original subfolders with my photos.  Apparently 10 PSE does not allow me to move folders of photos in the Organizer, so that the pictures stay connected.

  PES 10 offers 3 options for restoration: Original, personalized and customized, keeping the original structure of the file.  Here's what happens to each:

  (1) original creates new folders with the old names and the structure of the tree, parallel to the tree Windows 10 has instead of inside the tree Windows 10.

  (2) custom with the original structure of the file is the restaurant where I want (within the SusanPhotos) but retains all branches superfluous-instant initial tree of Windows XP, production: BONES (C), users, Documents, Susan, SusanPhotos, Documents and settings [carried over from the old computer], Susan, My Documents, SusanPhotos, Roma-Italy and Italy-Puglia and so on.

  (3) custom (without checking the original file structure box) makes every SusanPhotos but without any organization: OS (C),..., SusanPhotos, Italy-Puglia and Italy-Roma and all other folders at the same level instead of in their original nested groups with subfolders.

  The first two methods you end up with a tree that is chaotic with two parallel trunks or a single trunk but with several redundant layers carried over from the old computer.  The third ends with no tree at all.

  One solution would be to make a Custom Restore with the original structure of the file and then use PSE10 to move the folders that I would like.  However, AFAIK, PSE10 I cannot move entire folders of photos, only of individual pictures.  With thousands of photos in hundreds of cases, the time required for the movement of individual pictures is prohibitive.  PSE10 allows me to move the catalog folder, but apparently not the folders containing the photos.

  The result is that at this time I have no solution to my problem.  Can you help me find a way to restore my photos while keeping their original organization?

  You simply use the 'Files' Panel on the left. Your folder tree appears. Simply, you drag and drop the folder to move with all its subfolders in the desired master file. That works exactly as in Solution Explorer, so be patient, you receive no message of progress until it is completed.

  You did a good job to understand the situation. I think that might help you is to understand that changes in the way default folders are created in a different version of Windows can be ignored if you do not use these structure 'default', from the shortcuts to your main folder of the user.

  I create a master folder 'My Photos' directly under the C: root.

  When I restore, I use the "custom" choice, as you have discovered, I only specify this folder in the restore process, and I completely ignore the default shortcuts to 'Documents' or 'Image '.

• Problems of displacement of the layers

  I've been a user of items for 10 years, using ss12 since June. Recently, I had a problem of displacement of the layers inside and between files. When you work on a file, if I try to drag and drop a layer it just snaps back to where it was. I can move the layer with the arrow keys, but it fully takes to long. I do not understand why it started earlier past. I can open my previous version, PE 6 and move layers I have always done, but since I paid for upgrade to ss12 it would be nice to be able to use it. Any input on how to fix this would be greatly appreciated! Thanks in advance, Kirsten

• Open a displacement map of 32-bit without color management

  I have a point exr floating 32-bit displacement map extracted Mudbox.  I would like to open this file in Photoshop without messing with my values behind my back; assign profiles color and which do not.  In the color settings, I asked to invite me on the profile mismatches and missing profiles.  However, the option is greyed out who says: 'do not profiles set.  Is this all that I can do to get the PS to let my only darn values?  I just want to interact with the raw values in the file and paint on some small differences.  Thanks for any advice.  I am at a loss for now.  Nothing that I have tried gives me the same result in Maya after that I saved my card out PS

  Thank you

  Awesome!  But can you explain why my renders out radically different after that just open the file in photoshop and saving it right back?  To do something to my values behind the scenes.  I got it to work with 32-bit targets because I was able to change the color space "linear greyscale" (or something very similar named).  If I did not convert the color space in which I had different makes in Maya with hair as well.

• Cannot open the filter saved in AE as a file filter DM says PP. displacement map is missing.

  Cannot open the filter saved in AE as a file filter DM says PP. displacement map is missing. Also get a message that the AE file format does not match the sequence. Ask me to retain the existing settings or sequence - or track work. Haven't tried dynamic link as well - no chance. I'm a noob, so might be something real simple.

  Thank you

  Other features such as text, or shape layer, that do not exist in PrPro, or effects can be translated when you export your AE project as PrPro project. Similar things happen when you replace a clip (or a group of clips) by PrPro chronology by dynamically linked composition AE: titles, quite a few effects and transitions are not translated (at least correctly).

  However, dynamically linked composition AE is considered a composite PrPro. Therefore, there should be no problem seeing the result of applying any effect within a dynamically linked composition in the chronology of PrPro. If you have some difficulties with it, please provide a detailed explanation of what you want to achieve and what you are doing exactly.

  I know that this question. It is a breach when downscaling interlaced footage of progressive output without any deinterlacing. If it appears inside the first program monitor, set it to look at a single field.
