Creating a customised triangle wave
Hello,
We are using Labview to create a signal to control the motion of a scanning galvo. We would like to create a triangle wave so that the galvo scans back-and-forth uniformly, but to ensure smooth changes in momentum, we need the "corners" of the triangle wave to be slightly rounded. What would be the best function to use to accomplish this?
I am using LabView 8.
Thank you,
Moor
Hi Moor,
You can create a triangle wave by use the triangle waveform.vi. LabVIEW has a lot of options to create triangle waves. Searching LabVIEW for triangle wave will give you all your options for it. Smoothing out the corners can be done by using a waveform graph property node and selecting the smooth update. Here is a link to a kb that contains information to waveform property nodes. Here is also a link to another discussion forum who discusses on how to smooth waveforms.
I hope this helps!

Why does my ouput signal produce triangle waves when i want sine waves
in labview i use daq assistant to create a output voltage signal to create a sine wave. when i connect it to the opscilloscope it reads triangle waves. can someone please tell me why this is.
Solved!
Go to Solution.9172 is a chassis so I would need to know the module you are using, too. You should try the example:
%PROGRAMFILES%\National Instruments\LabVIEW 2012\examples\DAQmx\Analog Output\Voltage - Continuous Output.vi
It shows you how to create a waveform to generate, you could use that piece and feed it into your daq assistant. -

What are the steps in creating a customised report?
Dear Experts,
can you help me with your expereince what are the steps involved in creating a customised report?
Who generates the requirement?
Who prepares the functional spec and what information it contains?
Who approves the functional spec once it is prepared?
You can take the followig case as an example:
The customer requirement is that a report can be run for everything that is received in a given area and compare the price at which the material was received to the standard or moving average price in SAP.
Here, what information you will give to ABAP ers to devlop the report?
I would appreciate if anyone can help me with the entire process.
Full points to be awarded for a satisfactory reply.
Regards,
Ranjanhi
>Who generates the requirement?
client or end user
>Who prepares the functional spec and what information it contains
there should be a specific format and it is to be filled by the functional consultant

How to measure the slope of a triangle wave
Hi everyone,
I'm looking for a way to measure the slope of a triangle wave, which changes every half cycle of the wave. I have the triangle wave out of phase by 90 degrees so that it models the behavior of a cosine wave, and essentially all I want is a way to measure whether the slope is positive or negative. The idea is to use this information to stop another signal running at the same time at the halfway point of the cycle of the first signal, so the first wave can continue back to it's starting point and the second will start again at the completion of the first wave (as it begins the second cycle)
I'm using LabVEIW 8.2.1 if it makes a difference
Thanks,
Ben
PS. Is there a way to close threads you've previously posted on this forum? I started one yesterday (or possibly the day before) with a fairly vague question in it and it's now redundant after I made some headway on my own, and I don't want to clog the forums upI'm not sure how you're using this data to control anything, so I'm not sure what the best implementation would be. You will not be able to get any data out of the loop until it finishes (gets a True value at the Stop If True terminal (sort of)), so if you want to have the loop running constantly, you need to put your control code in the loop with the generated data. Otherwise, you could generate your boolean array, and then wire it and your control array into a for loop, and do a point by point comparison to see if you should be controlling.
The new example.vi has two examples to give you a rough idea what I'm talking about.

How to create 8-ch. .wav, as per Charles at NAB
Please list all the steps necessary to create an 8-channel .wav file from input files that are either 5.1 and 2.0 AC3/E-AC3 or .wav files. There may be some file-naming conventions involved--and name-changing. Channelization may also be an issue.
Warning - here be dragons! IOW, you can do it, but at present it's a bit 'clunky'...
The basic process involves you starting with a multichannel file, with nothing in it. You create this by clicking on 'New File' and selecting 'custom'. This lets you create a file with as many channels as you want. You do this, and you then have an empty file block on your screen. At this point, any files you want to put into it have to be opened, and ideally converted to individual mono tracks (easy option to do this in the Edit menu). Now, in your multichannel file, you have to turn off all of the tracks except the one you want to insert into. The channel controls for doing this are at the RHS of the waveform. Open the track you want to insert, and copy it. Now return to the multichannel file and paste it to the active track. Repeat with all the other files you want to insert, and you have an n-channel file with your 5.1 or whatever tracks in it.
Additionally, you can now open the Channel Mixer on this new file, and you'll get the option to alter the levels on individual channels if you want. Save the result, and you're done.
Now, I'll be the first to admit that this isn't yet perfect. But hey, the fact that it works at all is quite something, considering how long we've waited for it. -
What is the difference between triangle wave, triangle waveform, and triangle pattern
For generating a triangle waveform, I have 3 vi's that I could use. Signal Processing -> Signal Generation -> Triangle wave.vi, Signal Processing -> Signal Generation -> Triangle Pattern.vi, Programming -> Waveform -> Analog waveform -> Waveform generation -> Triangle waveform.vi.
What is the basic difference between these 3. I understand that all 3 have a different input set and I can use them according to what combination of input data I have. Is there any specific case for which each of them is used?
Solved!
Go to Solution.so, does this mean that I can not use triangle wave and triangle pattern to generate an actual waveform. Why I am asking is because I tried checking the waveform on an oscilloscope. The waveform generated by triangle waveform.vi is visible on the oscilloscope but not the one generated by triangle pattern and triangle wave.
the attached vi CreateWaveformTest.vi does show up correctly on the oscilloscope.
The other vi, createparttern test.vi shows up correct in the waveform graph but I am not abe to see it on the oscilloscope. comes up as a straight line

Comparing sine and triangle waves
hello everyone,
i'm a student from belgium and i have to program an BLDC motor with labview. for this i need a PWM (pulse width modulated) signal. i want to do this by comparing a sine wave with a triangle wave, theoretically this should give me
block wave with different duty cycle. i have added a picture to make my question more clear.
as you can see there are two triangle waves to compare with the sine wave, every time one of the triangle crosses the sine wave a pulse is generated and stays high untill the next cross.
thanx in advanceHello,
When i tried to reproduce this problem, I couldn't succeed in it.
While looking at you jpeg I noticed that you have connected something to the channel input of your ddt to waveform convertors. You should remove this (except if this was your intention) and then everything should work.
If this doesnt work, then you can always use the file attached to this post.

Just seems to make a mockery of the hours, days, and years that many of us has spent earning our degrees and learning our skills.
Work on it and ask specific questions with examples of what you have done and you'll get a much better response. -
Fastest Way To Create Ultrabeat Instrument From Wav Loop?
Hello, can anyone share the fastest way to create and instrument from a WAV file?
I know you can convert a wav to ESX24 instrument but I use Ultrabeat not ESX.
Im finding my self divinding each shot into region and then exporting that to its own file.
Is there a faster/simpler way?
-ThanksYou're right! It does work, however, if you follow these steps:
1. Right-click on wave file in Arrange and choose "Slice at Transient Markers" or use the corresponding key command.
2. Select all the split regions right-click on them and choose: Convert > Convert to new audio file(s)
3. Again, with all the regions selected choose: Convert to new sampler track.
4. Now launch Ultrabeat. Click on the Import button anc choose the .exs file you've just created (will be located in your project folder). Then drag the audio files into UB as desired.
You could skip Part 3 altogether and simply slice at transients, convert to new audio file(s) and then in a new kit of UB drag them into the sample window of OSC for each part... -
We want to create a test Magic Triangle where we can test major changes before deploying them in production.
We have a Mac Xserver 10.6 (matches production), Active Directory at Windows 2008 R2 functional level (Production is at 2003), and NetApp filer running OnTap 7.3.4 (Production is at 8.1).
We have augments defined to set the user home directory in Open Directory. This overrides the AD setting in production. Our test environment does not request the home directory attribute from Open Directory.
I have turned on Diretory Service debugging using:
sudo killall -USR1 DirectoryService
sudo killall -USR2 DirectoryService
From the debug logs I see the production Mac OS X client querying AD for user attributes and then OD for the augmented records:
Here are some relevant records from the client debug log in production:

The big difference is the search for LDAPv3 records. In production, the client requests these attributes:
Requested Attrs = dsAttrTypeStandard:GeneratedUID;dsAttrTypeStandard:HomeDirectory;dsAttrTypeStan dard:NFSHomeDirectory
but in the test environment the list is shorter:
Requested Attrs = dsAttrTypeStandard:GeneratedUID
We see the augments in both ODs so I don't know why our test client is not requesting the necessary attributes to mount the user's home folder.
The client connections to AD and OD do not show any obvious issues. Using dscl to read records from AD and OD works fine.
Can anyone explain why a Mac OS X 10.6.8 client would not request the augmented attributes from OD when also connected to AD?Thanks for your reply ..
I now see what's going on.
so if I simply disabled kerberos of the existing OD as described here:
http://docs.info.apple.com/article.html?path=ServerAdmin/10.6/en/odfd7bf26f.html
it should be fine ?
Mac OS is serving a few macs ; but most machines are Windows PCs now.
What it does do however, is providing the mail; calendar and wiki server.
My understanding is that if I do not run OD; it will be much more work to allow mail for AD users to work. And transferring the current mail files is going to be a pain provided it uses stuff like BC86E956-9107-4761-8EE1-C58D4019F559.
So my plan was to bind the OD to AD ; create the same username on AD so OD would keep all the apple related entries (mail entry, GeneratedUID etc..)
Re-creating all users from scratch looks like it's going to be a long task otherwise
The other thing I'm worried about is that I would loose aliases. The way OD lets you create aliases is great; and I believe this isn't possible with AD.
Last thing, when I last try to make the os X server to bind to AD ; it then wouldn't let the admin authenticate in workgroup manager kept telling me the password was incorrect.
Which was very weird as the password would be accepted everywhere else (ssh, email, wiki etc..)
Only workgroup manager would complain that my login details weren't correct. And in the mean time, I couldn't edit any of the remaining users.

Creating script to split wav files
I'm using AA3 to record my vinyl collection for burning on to CD & I also use mixedinkey to ascertain the key for each track.
Quite often the keys can be different at the beginning & end of each track so I want to create a script that will save the 1st 2 minutes of a track as say "filename(1).wav" & the last 2 minutes as "filename(2).wav" so mixedinkey can analyze them separately, is it possible?
I have a lot of tracks that I'd like to do so automating it is the only way forward.
Thanks in advance.Thanks for the replies.
I'm getting there. I created the script below that deletes all but the 1st 2 minutes, this can then be run in batch processing with a file rename mask to get the desired result for the particular file I recorded the script on. All subsequent tracks of different length confuse it as they're not 18413567 samples in length.
Is there any way to say "end of file" instead of specifying a number?

I want to create a "clean" sawtooth wave with my own inserted array.
I have a PXI module with a fgen5411. I can make a arbitrary waveform with my own array. that's not the problem. The real problem is that if I insert a waveform array with 4096 steps, Labview divides the steps and the 4096 steps are no longer 4096 steps but less. Because of this the created steps of the sawtooth wave excists one time out of 4 points, and the other time out of 5 points and so on.
I use the "create arbitrary waveform" and the "app sequence waveforms" VI's. And because I use the create arb waveform VI, I have to devide my array values with 10000 so that my scale comes between the values �1 and 1.Hello Ben,
I solved the problem I had with the number of points. The problem was that I was using 1/5 part of the �create arb waveform� scale(between �1 and 1) so that labview generated five points per step.
Now I can generate a sawtooth with the full 12 bit resolution. But the problem now is that the sawtoothsweep begins negative and ends positive. This is strange because the array I load from file excists out of positive numbers. What I want is a sweep beginning at 2 Volt and ends at at least 8 Volt. I tried to change the offset of the �app sequence waveform� but this did not work. The offset does change, but it can not be made positive. I also tried to devide my array so that it fits in the positive scale of the �create arb waveform
�(between 0 and 1), but this also did not work. Is it possible to make a positive sweep with the 5411 in ARB mode?
I send you screenshots from the part of my program. First I load a array from file and devide this by 5000. Then I create a waveform and load this into the �app sequence waveform�.
Ben, I hope you know what I am doing wrong, because I don�t.

Creating additional customised tabscreen under header data for me21n
hi all.
i have a requirement for adding extra tabscreen (subscreen) undr headr data of me21n purchase requisitions .
and other thing is i want to know how we can raise an eror message if the user has filled all data in me21n except in customised tab screen that i am going to create.
waiting for great answwr.
bye.
sita ram,Hi,
you can find tons of general info BADIs on this forum. So basically go to transaction SE18 and enter name of your BADI - ME_GUI_PO_CUST. Please read carefully documentation. There is button for documentation. In documentation you can find following statement:
The Business Add-In (BADI) ME_GUI_PO_CUST enables you to integrate your own subscreens into the Enjoy purchase order at both eader and item levels.
So it looks like what you need. You have description for each method of BADI in documentation as well.Definitely you will have to implement method SUBSCRIBE. You will define your own screen in this method. Then you have to implement PBO and PAI logic (check methods TRANSPORT_TO_DYNP and TRANSPORT_FROM_DYNP). SAP provides examples for each BADI. You can read the example of BADIs implementation in Goto->Sample Code->Display. These examples are very well commented. I am pasting just example of SUBSCRIBE implementation
DATA: ls_subscriber LIKE LINE OF re_subscribers.
* we want to add a customer subscreen on the item detail tab
CHECK im_application = 'PO'.
CHECK im_element = 'ITEM'.
* each line in re_subscribers generates a subscreen. We add one subscreen in this example
CLEAR re_subscribers[].
* the name is a unique identifier for the subscreen and defined in this class definition
ls_subscriber-name = subscreen1.
* the dynpro number to use
ls_subscriber-dynpro = '0001'.
* the program where the dynpro can be found
ls_subscriber-program = 'SAPLMEPOBADIEX'.
* each subscreen needs his own DDIC-Structure
ls_subscriber-struct_name = 'MEPO_BADI_STRUCT'.
* a label can be defined
ls_subscriber-label = text-001.
* the position within the tabstrib can be defined
ls_subscriber-position = 5.
* the height of the screen can be defined here. Currently we suport two screen sizes:
* value <= 7 a sevel line subscreen
* value > 7 a 16 line subscreen
ls_subscriber-height = 7.
APPEND ls_subscriber TO re_subscribers.
So basically you will define your new sub screen in this method. Do not forget that the BADI ME_PROCESS_PO_CUST is compulsatory for BADI ME_GUI_PO_CUST.
Cheers
