How to split signal into xy components

i am simulating a digital signal and viewing it on a graph, I would like to input x and receive the corresponding y coordinate.
I have a attched a screen shot.
If anyone can help, I'd really appreciate it! Thanks!!

Look into the Get Waveform Subset. If you set the duration to 1 sample (or dt if indexing by relative time), you should only get 1 element. Just use Array Index and you got your value.

Split signal into XY components

Hi,
I am new to LabVIEW but have spend a huge amount of time (mainly going round in circles not getting anywhere) trying to get my VI design working. All very frustrating since I know what I want the VI to do but cannot figure out how to implement it in LabVIEW (despite hours of searching in this LabVIEW forum and in the help files).
I need to....
Take a signal from DAQ Assistant, when the signal is at a particular threshold (user configurable via Front Panel) log the data to Measurement File and stop logging when the signal reaches a higher threshold (I tried using the 'Trigger and Gate' VI in Express but it doesn't allow user configurable values for thresholds (only integers)).
Then I need to read back the Measurement File and split it into its XY parts to display on an XY Graph (and keep it displayed on the front panel for user observation).
Any help would be greatly appreciated but please explain in detail as I've already played with LabVIEW for hours and hours and haven't got anywhere.
Regards,

Hi bunnykins,
I think you can try using normal greater than /less than comparison functions and log the data using the Write to measurement file with append to file option enable.I have attached the screenshot of the block diagram.Please have a look. Thanks and regards, srikrishnaNF

How to split image into smaller (same size) pieces?

Hi all,
My question is how to split image into smaller (same size) pieces, using Photoshop elements 13? Could anyone help me with this one?
Thanks!

Use the Expert tab in Editor (I think that is what it is called in PSEv.13)
You may find the grid helpful. Go to View>Grid. It will not print, but will help to orient you. You can set up the gridlines to suit via Edit>Preferences>Guides and Grid. If you want to partition the picture in to 4 uniform pieces, it would be Gridline every 50%, Subdivision 1. Also, go to View>Snap to>Grid.
Set up the Rectangular marquee tool: If the picture is 6" wide & 4" high, enter width=3in & height=2in.on the tool's option bar. This will be a fixed size.
Click and select one quadrant, press CTRL+J to place this quadrant on a separate layer
Repeat for the other 3 quadrants
You should end up with 5 layers : Background, and layers 1, 2, 3, 4.

How to Split field into multiple fields in Import Manager without delem

Hi
Is there any method to Split a record in MDM without using delimitter?
I dont want to use any delemitter My field content in Source is PRODLABELPACK and I want to split it into 3 fields in destination Field1= PROD
Field2=LABEL Field3=PACK
I know how to split it if the content is PROD_LABEL_PACK .But we dont want to use delimiter in the firld and want to use some substring function
Regards
Prashant

You Can use below FM SWA_STRING_SPLIT -
First Use READ_TEXT FM.
then loop into
loop at tline.
Here use 'SWA_STRING_SPLIT' -> Pass tdline and append the text into other internal table.
endloop

How to insert signals into multiple columns in db, dbtoolset

I have a labVIEW program that is currenly simulating voltage and a current signal using the DAQ Assistant. I'm using the database connectivity toolset. I am currently able to insert one signal into the database converted to a float(I can insert both into the same column as bianary but it needs to be stored as a usable format and in seperate columns.)
The problem I am having is at the DB Tools Insert Data block. I have the connection, dbTable, error code, and create table boolean being passed into it. Where I am a little lost is how to set the columns I want to store the multiple signals into.
If someone could break that part down for me that would be great. In short, I want to store voltage(channel0) and current(channel1) from the DAQ Assistant into their own respective columns in the db.

As I have often pointed out, the easiest solution to this situation is to dump the Database Connectivity Toolkit. Check out this thread and follow the references in it. If the DCT weren't in the way what you are wanting to do would be very easy.

Can Calibration Protocol and how to devide signals into CAN-Bytes and backwards

Hi,
i have two questions about working with NI-CAN Hardware:
First: How do I divide my signals (esp.:rpm,boolean variables,...) to put them into the CAN Message Bytes?
example:
rpm range: 0 to 8000
resolution:1 step means 1 rpm
On rpm = 2000 the resulting bitcoding is as follows:
[00000111 11010000] [highbyte lowbyte]
Next I have to store a boolean bit(false/true is set to true) additionally into the highbyte. the resulting bitcoding is [10000111 11010000]. CAN message is now ready for dispatch. The listener have to take the individual bits to get the rpm and the booleans state.
I programmed a CAN-DLL in Visual C++ for a CAN Dongel. In C it is easy to split the CAN Message into the
ir signals. Shiftoperations (<<,>>) make this possible.
Second: Next step is the use of CCP2.1 (Can Calibration Protocol). Did someone use already once CAN Calibration Protocol with Ni-CAN hardware? If, I would be pleased about example files or contact.
Thanx for listening and sorry about my english. I wait strained for answers.

Schön jemand deutschsprachigen gefunden zu haben.
Mittlerweile hat sich etwas neues ergeben:
Eine in LabVIEW6.i erstellte Anwendung kommunziert via CAN. Die Sende- und Empfangssignale werden in einer DLL (Aufruf externer Bibliotheken), nach empfangen einer CAN NAchricht, zusammengesetzt oder für den Versand zerlegt (in die 8 Datenbytes entsprechend einer Schnittstellendefinition).
Somit übergibt Labview lediglich komplette Zahlenwerte (Drehzahlen) und BOOL Flags (Bits), die in der DLL, wie oben beschrieben, bearbeitet werden.
Diese DLL greift schließlich auf entsprechende CAN Treiber DLL's zu um Daten zu versenden oder abzuholen.
Zusätzlich soll nun die NI-CAN Karte integriert werden. Der erste Ansatz war die Lösung in LV zu realisieren. Dabei müsste je
doch die gesamte Schnittstelle nochmals integriert werden (doppelter Pflegeaufwand).
!! Deshalb suche ich nun nach einer Lösung in C oder C++ mit Visual Studio .NET. Beispieldateien (in C oder C++) für CAN starten, CAN schließen, CAN reset, CAN read und CAN write wären sehr hilfreich.
Die Modifizierungen der Signale werden in der DLL bereits erledigt. Ich benötige lediglich einen Zugriff (in C oder C++) auf die NI-CAN Karte, um die bereitliegenden Daten zu versenden(CAN write), bzw. empfangene abzuholen (CAN read).
Das Format einer CAN Message:
1. Identifier
2. Datalength
3. DataBytes[8]
Falls Sie mir helfen können,Beispieldateien zu finden, wäre ich Ihnen sehr dankbar. Leider habe ich bei ni.com nix gefunden.

How to split video into chunks for web?

Hi all, I have a movie trailer that needs to be split into chunks for the web, to be played as a flash file, I have never done this, so my question is at what level do i do this, the timeline?, is there a program that does it?, can flash do it automatilly?, is there a good progam out there that does it?. It has music and very specific sound edit points, and like I said I never done this so any help would be great.
Thanks

The bandwidth of the website will dictate the picture size and the data rate the server will cope with. Full screen motion video at 25 fps is too much for most web sites.
If you are supplying this to a web designer, ask them what size and data rate they want.
If you are doing this yourself you would have to experiment with how the system copes when downloading the files in practice.
For example, for one of the websites we have we use one of the Squeeze standad presets in the Flash Video section of 320x240 @250 mbps for 4:3 SD video. This is to fit on a page of text with buttons with a video image of about 1/8 of the screen.

How can split data into multiple sheets using an excel template

Hi all,
I'm using BIP 10.1.3.4.1 upgrated with the latest rollup patch, 9546699.
I followed the example inside the article "Real Excel Templates 1.5" (on the Tim Dexter's blog)
http://blogs.oracle.com/xmlpublisher/2010/05/real_excel_templates_i.html
and I built my report directly from an excel template containing only one sheet (plus the XDO_METADATA sheet), and for one sheet it worked fine !!!
Now I need to add more sheets to the template.... and I have two big questions:
1. if I need to create a second sheet which contains almost the same data (with a different layout), I saw that it is not possible to map a value to more than 1 cell....so if I map a value in the first sheet, I can't map it in the second sheet (because it's already used in the first one).
How can I map same values into two or different execll
2. if I need to create a second sheet which contains another dataset (completely different from the dataset in the first sheet), I can I do, considering that every BIP report is based on ONLY a data source.
Tim wrote: The most impressive, for me at least, is the sheet 'bursting'. You can split your hierarchical data across multiple sheets and dynamically name those sheets
but I didn't yet understand how this bursting it's possible.....considering what I said above.....
Surely I've a lack of knowledge.....but anybody can help me to understanding the "multiple excel sheets" black hole ?
I'll appreciate any kind of help
Thanks in advance

args[0] will not take the entire string Test Hello
World. It will take only Test, so only one element in
the string array.What are you talking about?
He's running the Test program which receives two arguments:
args[0] = "Hello"

How to split data into tables based on the entries in a column?

My problem is very similar to this thread: how to link data from one numbers sheet to another sheet, however I could get it to work the way described there. I have one big table for entering data (the first one). I would like to have a few other tables populated automatically based on the entries in one of the columns of the first table. In my example below I put everything in one sheet for clarity. The selection to the other tables is to be done on the column "fruit" in the first table. (second one is "oranges", then "apples" and then "pears" -- had to cut the width of my screenshot due to the limitations of Apple's forums).
Here is what it would look like, just cannot figure out how to make it happen automatically.
Tried also importing similar Excel example to Numbers, but the import did not work correctly.
Any help will be appreciated.

Larry,
Here's an approach that I've used...
In the Purchases table, Aux column, the expression is:
=COUNTIF($A$1:A2, A) & "-"&A
Fill Down
This expression builds a string that identifies the item and the ocurrance of that item.
The Date column of the Summary tables, cell a3, contains:

Tabular report, how to split row into two lines per record

Hi, I have a tabular report based on a collection. The collection has 15 fields and appears horizontally across the screen. I would like to have a break after the 5th column so that each row is on two lines instead of one. Is this possible...any information would be helpful.
a shortened query is: and I would like the break to be between c028 and c029.
thanks
Karen

Hello Karen,
>> and each field needs to be updateble ( concatenating two fields does not allow for that).
Did you notice the ‘<br />’ component, as part of the columns concatenations?
The following example is using the same principle – every two updatable column, from the employees table, are sharing the same tabular form row - http://htmldb.oracle.com/pls/otn/f?p=22710:420 . The report query is:
select apex_item.text(10,first_name)||'<br />'||apex_item.text(11,last_name) col01,
apex_item.text(12,phone_number)||'<br />'||apex_item.text(13,email) col02,
apex_item.text(14,salary)||'<br />'||apex_item.text(15,commission) col03
from employeesThe same principle is being used to define custom headings.
Hope this time it will be more clear.
Regards,
Arie.

How to split the records into two parts

Hi experts,
I have a field with 75 char length, this field have records also, Now i want to split the field into two differnt fields. That means upto first 40 char goes to one field, from 41st char to 70 char goes to another field, for that how to split record into two parts.
Plz advice this,
Mohana

Hi,
Do the following:
f1 = fsource(40).
f2 = fsource+40(30).
where fsource is the 70 character original string and target strings are f1 (length 40) and f2 (length 30).
Cheers,
Aditya
