• How to sample multiple sensors in a vital task?

  I need to a thermocouple sensor and voltage sensor in a vital task of the sample. My hardware configuration includes a cDAQ-9172 chassis with a NI9211 TC module and a NI9221 voltage input module.

  I started with the example C code for thermocouple measurement found here:

  Instruments\NI-national DAQ\Examples\DAQmx C\Analog In\Measure Temperature\Cont Thrmcpl samples-Int Clk\ContThrmcplSamps ANSI - IntClk.c

  I then added a few lines of code for the measurement of additional tension.

  The task runs for about 20 seconds, until the buffer overflow with the error 200279.

  I can run task, thermocouple or voltage, indefinitely. It's only when I include them both in the same task as the buffer overflow.

  I have tried many combinations of sampling rate, the size of the buffer and DAQmxRegisterEveryNSamplesEvent nSample size.

  Below is the code I'm running.  Changes to the original file are marked in bold. I've attached a screenshot of the output of command line.

  Can anyone offer a C program example showing how to sample multpile sensors permanently in a task?

  One more thing I've noticed is that the size of the data [] has not be increased to include additional channels. Wear in 2000 and also to increase arraySizeInSamps (parameter 5) and 2000 to the DAQmxReadAnalogF64 function call. Given that it was only the value 1000 samples, it will get only 500 samples per channel causing the overflow.

• How to sample the color with the eyedropper tool and have it be the foreground color?

  How to sample the color with the eyedropper tool and have it be the foreground color?

  Use the keyboard shortcut to set the default foreground sample.

  The sample of foreground (top left in the screen shot) is visible and you just click on the color with the eyedropper tool to change.

  You can also use x to exchange the undertone in the foreground if you want to change that.

  

• How to sample the color gradient

  How to sample just a point in a broken down?

  I looked at my preferences of pipette. Everything is checked. I saw an option that would let me do what I wanted.

  Any suggestions?

  Try this: draw a filled rectangle of gradient or make a copy of your gradient filled object.

  Go to object > expand. The slope becomes a mixture and you can choose any stage you like for sampling.

  Note that, according to fussy how you are, you can choose less than 255 objects (steps) case of extension.

• How to create the texture of noise - Illustrator tips

  Hello. I saw this on one of the tips section and technical Illustrator artwork and I was wondering if anyone knew how to create the texture of 'noise' in Illustrator?

  What I have done in the past to achieve a similar effect was to finish my illustration in Illustrator, then bring this work in Photoshop, and paint over the areas you want... but it looks much nicer than the results I've gotten. If this can be done in vector, it would be another plus!

  Does anyone have any idea they could share on this?

  Thank you!

• How can I use SQL/CUBE to figure out total?

  How can I use SQL/CUBE to figure out total?
  
  Thank you.
  -JC

  Of course, you can do this by using the cube. But cube will produce all the possible combinations of summary. We can filter the unnecessary summariies having clause using the group_id function which is a binary encoding of the columns that are summarized. Below for example, as applied on the table SH.sales.

  Select channel_id, promo_id, prod_id, sum (amount_sold)
  from the sale
  Group of cube (channel_id, promo_id, prod_id)
  having grouping_id (channel_id, promo_id, prod_id) (3, 5, 6, 7)

• How to make a 3D cube?

  How to make a 3D layout on Mac cube?

  Well, it can be done.

  Inventory

  1. rectangles, 2
  2. parallelograms, 4

  Exploded diagram:                                                                                                Completed:

  

  Individually, you may want to organize each shape selected and in the tab object, set dressing to zero. This will facilitate alignment object later.

  Insert a rectangle and duplicate by option + do swipe an offset as shown above. Duplicate this last rectangle with an option-drag that it will become your playdough for the first form of parallelogram. Select the third rectangle and then on the Format menu, choose shapes and lines: make it editable. To the four corners of the rectangle will have now taken red, which you can pull and push to get to the first form of parallelogram. Click outside the shape to dismiss the Red edit handles. When you have an approximate parallelogram shape, option + do slide once to do the opposite wall of the cube and then option-drag to another that will flip you (via the tab reorder), to make the top and then option-drag to reduce the shape of the bottom.

  At this point, you have the above exploded view. You don't have to worry when you drag the pieces together and they do not correspond exactly. Once more, you use the Format menu: shapes and lines: make editable to fine tune your editing of parallelogram in their locations next to the cube. When I did, I selected the content of all of the cube and applied 0.5 pt gray border lines, and each face of the cube is 38% opacity. Fill color for each face of the cube is optional.

• How constantly sample meter signal for quadrature linear encoder

  Hi all

  Trying to permanently change value of Schneeberger linear encoder quadrature at certain frequency as 10 Hz of the sample and the output to the text file. Everything I choose in the external clock that I can't run the DAQ assistant. No one knows how to fix? I don't know what kind of clock can be used.

  I have read a few replies that ppl would connect to an another sample clock in parallel with the meter channel. But I don't know what is the principle of operation of this method.

  I spent already as 10hours on it. Could someone tell me that some information?

  Looking forwad to your help! Thank you very much!

  Best regards

  George

  Hi George,.

  You'll want to use the DAQmx API rather than the DAQ Assistant.

  The task of the encoder itself would look like this.  You need not use the trigger options.

  The problem is that you will need to generate a clock from another source that the card is unable to generate examples of clock counter directly.  The simplest is probably to use the second counter.  Here is an example showing how to use a meter to output as a sample clock (although the example shows the analog inputs, simply replace the task of analog input with the task of the encoder shown in the previous example, I linked).

  So, you would use a counter (say ctr0) for the task of the encoder, and then the other (ctr1) meter for the generation of sample clock.  You must specify your task of encoder using the InternalOutput of ctr1 as the sample clock (if the internal counter output appear in the drop-down menu, click with the right button on the terminal and select the e/s name filtering > include Advanced terminals).  Start the encoder task before the output task (although given that both are running continuous it doesn't really matter that much).

  In addition, 10 Hz is not too fast.  If the exact date is not as important and the above seems a little overwhelming, it might be easier for you to just run a loop of 100ms clocked by the software from example like this.  Note that the exact time loop pourrait will vary from cycle to cycle, so this method is not very good if you use sampled data to perform calculations of rates.

• How to export a textured animation of Photoshop?

  If I have a textured, and animated character how to export as it seems? If I export a movie, it shows just a white character animated on black background.

  Can you give us a bit more information?

  You imported the character using libraries CC?

  You use file > export > render video?  What are the settings that you use it if so?

  I just did a test with this and it seems to work fine with full textures.

I know there is a way to do it, but when I tried tutorials that Adobe how to do this, it does not create a nuance and I don't have the same options that are listed. Illustrator help | Models of it is said to select object, then go to Edit - as a reason I have not have a schema option to define and I currently have CS6. I can make a texture, but I can't make a distinction, so my question is what am I doing wrong?

• How to sample audio hearing re-

  For the record, there is the idea, to set the bit depth of 24 bit and 192 kHz sampling frequency. This is to get the best possible recording quality. The size of the file is not under discussion at the moment.

  The final product will be an Audio CD on 44.1 kHz and 16 bit.

  How hearing re - sample digital 192 kHz and 24 bit 44.1 kHz and 16-bit recording? He put internal digital to analog and then re - scan it to 44.1 kHz 16-bit. Or it will just be in mathematics?

  In the case of mathematics own-works, that help to do with 176,4 kHz and 24 bit recording? So there will be just a division by three.

  Or are my unnecessary thoughts?

  Classic multitrack recording with Audition CC14 what would you recommend?

  If you want to publish classic recordings on CD to 44.1 k, you waste your time anyway to 192 k registration - you might as well save to 44.1 k in the first place and not introduce even the slightest possibility of any degradation of the conversion. I do it: I have been doing for years and has never received a single complaint about it! If you want to save directly in the hearing, then I would record using 32 bit Floating Point - which is the internal format and has a much wider range of dynamic (for purposes of setting) that any integer format will be.

  Despite all the arguments incorrect you may have heard otherwise, the chances of hear you even the slightest difference through sampling at ridiculously high rates have been proven by rigorous independent tests, being non-existent. There was a case to do this back in the bad old days of brick wall filtering, but now that almost all converters using massively high levels of oversampling, there is absolutely nothing to be gained at all, unless you save bats for an audience of dogs and cats.

  The resampling process is entirely digital. And it is based on the computed interpolation.

• How to add a texture wood?

  I have a background image that resembles the planks of old wood (like the side of an old barn in the West) and I want to put the text and image on another. However, it looks fake. Is it possible to simulate the texture of the background image on the text and graphics added to give the impression that they were painted on wood barn?

  As always, thanks for the help anny

  Hello

  You can use the different blend modes to achieve this effect. Choose the best blend mode depends on a few things (color graphics, how dark is your background, etc.). If in doubt, experiment with different blend modes until you get the results you're looking for.

  Here is an example that I hope will help you in the right direction:

  

  simply keep the old planks of wood as your background layer and play with different text and graphics layers blending modes. You can change most before messing around with opacity to make look it more subtle.

  Please report if you have any questions.

  Edit:

  you could also add a layer of FX with bevel and Emboss text/graphic:

  

  adjust the parameters to your liking, and it should give you a nice effect.

• How to make a perfect cube

  How to make a cube perfect 3 in sequels?

  I create a square of the cube face then changing every time the anchor point (top, side and bottom both) I have duplicate 4 times and rotate to re-create the cube, but they do not affect the good way, I mean there is always a space or they merge... If I press ctrl or SHIFT the program don't help me make them aligned

  How can I solve this problem?

  to be faster you can just rell me how I Center the anchor point of a 3d layer? I mean Center the value of Z, the deep... If I put 0 as z's on the figure

  as on a 300 x 300 point Z index will be at 150, but on an irregular figure? How can I Center it?

  Ive done with solid, but I want to do with the rectangle tool, is possible? Z anchor into solid is easy to install, just grap to 150 if your solid is 300 x 300, but ho you can center the Z point with the rectangle tool? is it possible to make a cube with this tool without having to manually focus a layer? with solid is easy just put the Z anchor to the theoretical centre (I hope you understand me in this theoretical Center XD I don't know how to explain it) then double 5 times the layer and rotate 90 degrees to make the cube... but very easy with the rectangle tool is a mess D:

  No, there is none of these tools, but you can do with expressions.

  ALT/Opt + click Layer Anchor Point stopwatch and type [ (left bracket) 0 (zero) ,(comma), 0 (zero) (comma).] Then pick whip layer anchor to each form of size width (first number) or height (2nd number). [Then type 2] (divide by two, right support) and press enter on the numeric keypad.

  

  You can now change the size of your rectangle and Layer Anchor Point will be adjusted automatically.

• How to mount a texture?

  I have a texture which is square shaped and im using as an overlay, how can I adapt it to a path?

  I will try

  Here is your art

  with the windows and the body of the van

  

  But what you need is only the body chosen like this

  

  Place now you texture behind it and select the outline of the body and texture and now try to make the clipping mask.

  Do not select and type or other paths.

  Just the body contour and texture.

  You're good to go.

  Windows will show because they are on top, the contour of the body and therfore above the hidden texture.

  So everything else.
