Logical operations on a string of bits

• Creating a string of bits to send through questions series VISA, complete noob here...

  Hi all

  I'm trying now, to browse the values I have on my collection of GUI and with these, construct a message to send through VISA.

  I have the usb-> rs232 cable and NO, and I have attached a connector, with the pins 2 and 3 tied together so that I can loopback and see the messages I send.

  I'm supposed to (from the instructions that I read on a design doc) will send a message of length of 24 bits.

  And please bear with me, I've never worked on this low a level before, nor with the serial interfaces, so I can be completely off on how I'm doing... and this is my

  first really relay with LabView for this project.

  I have some time execution of every 20ms in a loop.

  I have a structure of the event looking for user actions on my front.

  I also breast that everything in a loop, a flat sequence structure... my assumption was, every 20ms, the flat sequence structure would run, except where it is interrupted by an event... that could trigger and then continue with the flat structure...

  I have seen that the entry VISA (and read) take a string.

  So, I started the flat structure with build my string of bits/bytes outgoing... first section is coded hard and then, through the two sequences, loop it and based on the values of the controls within each cluster, I concatenate to my outgoing string... in which case, I send by the visa by the closure, and post it on the message indicator.

  It seems that I can send on only 8 bits at a time through VISA... so, I try to understand (and I wonder people with the req on this part) why they said to send such a long chain... or am I supposed to send each message of 8 bits, one at a time?

  If one bit 8 message at the same time, I wonder how I have let him know when I am finished?  I have heard and read things about start and stop bits, but I don't know where to put them.

  In addition, is the string that I'm supposed to put them together to send something waiting for data series bits/bytes? I saw a reference to a string of bytes while the research, but I Coulnd't ' t find a piece of string byte on the pallets.

  And when I run the present (a simpler example of my real application, simply to show here the parts I am trying to figure)... the message echoing again to me is:

  111000010000\n

  When if I have all the tubes with a value in them... I want to get something new like:

  1110000111111110111111110\n

  I'm also noting that messages do not seem to be transmitting every 20ms... seems only to get a message back when when I trigger an event, as the option switch on the LED.

  In any case, I'm confused, I think that, on certain basic principles and hope someone can maybe send me some links or give me some advice on where I'm wrong so seriously...

  Is my construction of the right to follow path string message?

  Is something wrong with the flow of the program... the events + flat sequence structure?

  I received this property by searching for forums and other papers OR, but I'm stuck sort of and confused I think on some concepts with read/writes...and possible VISA my flow control.

  Any suggestions and/or links GREATLY appreciated.

  Thank you

  Cayenne,

  Your sequence structure is not necessary.  You have a dependency on the data, as well as the structure of sequence is not really do anything for you.  Seems to me that what you want to do is to build the table of your clusters that you already own and send the table directly in a > 0? function.  It will accept berries and an array of Boolean output.  You can then use the Boolean array to the Number function to create a U8.  Do this for each of your clusters and integrate the results in a table of U8 and fixed data.  Then use the array of bytes to the string function to get a string to pass in the VISA to write it.  Without loops or the necessary structures.  Any additional manipulation you need, I recommend to the byte level.

• go into strings of bits on a single byte (best practices)?

  I'm looking for a more eloquent way to convert:

  • Several strings of bits in a single byte.
  • Only string to array of bytes that represents the value of the number

  See the VI for an example functional but not scalable.

  Each string has a value of 0 or 1, and they will be converted to a single byte.

  I'm surprised there is no native functions in the section conversions which allows the user to do.

  I would like to change the conversion into a function with the following entries:

  • any number of strings of bits

  Output:

  • Byte or Word

  I'm on LabVIEW 2012 and I can't open your VI or Hoovahh modified version so maybe I write exactly the same thing, but this snippet does what you want?

  

• Im trying to install the Nvidia drivers for my new video card and its saying that my operating system (windows vista 64-bit) is not compatible, which means they are 32-bit drivers, it's fake.

  Im trying to install drivers for a Nvidia Geforce GTX 260 on my windows vista 64 bit computer. Every time I have try and start the download, it is said that my driver is not a 64-bit driver, which is false, and that my system is 64 bit, which is true. SO... after I click 'OK', it begins to download only to have another pop-up saying "Setup has detected that the system in use is not windows vista 64 bit" which it is. Basically its contradiction with himself. im confused.

  Im running windows vista 64-bit.

  I just upgraded to a Nvidia 9800GT, to a Nvidia GTX 260.

  In frustration, I deleted all the old drivers, but the new will not download.

  The first error says that the drivers are not 64-bit.

  The second error indicates the operating system is not 64-bit.

  Let the site nVidia Driver detect your video card. If it still does not work, contact nVidia for a solution... Mike Hall MVP - Windows Experience http://msmvps.com/blogs/mikehall/

• Must both x 64 x 32 to be installed on the operating system Windows 7 64 bit system?

  I noticed that both (x 64 and x 32) versions of Adobe Photoshop programs have been downloaded and installed on my Windows 7 x 64 system, are they correct?

  Yes, it is perfectly fine. Both versions installed. PS just like a traditional 32-bit application and a 64-bit version for systems with processor and operating system to run 64 - bit.

  Adobe:

  "The main advantage of using the 64-bit version of Photoshop is to access the amounts of RAM beyond what Photoshop can access as a 32 bit application. Photoshop can make the most of more than 4 GB of RAM only if it runs as a 64-bit application'.

  example:

  select col1 ,order_by,case when col1 > 10 then 0 else 1 end
  from tab;
  
  select col1 ,order_by,case when col1 <> 10 then 0 else 1 end
  from tab;
  
  select col1 ,order_by,case when col1 not in (10,11,12) then 0 else 1 end
  from tab;
  

  Regarding testing for null, decode the handles which, by default, anyway, so that you can get decode or case easily...

  select col1 ,order_by,decode (col1, null , 0 , 1)
  from tab;
  
  select col1 ,order_by,case when col1 is null then 0 else 1 end
  from tab;
  

• Boolean logical operation

  Hello! Recently, at work, I was responsible for creating the code that returns something on two Boolean State. Something like: If Boolean has and Boolean B, return if Boolean is and B no Boolean etc something else.

  At first I thought that the best way to do it would be a formula node with the return value is passed through a bunch of if else statements. Then I discovered that Booleans are not supported in notes formulas and forms knots are designed for writing formulas, and not for current programming, that makes sense.

  I came with two ways to do it, but I felt that they were both quite stocky and they suck if I had more than 2 Boolean values my logic on the basis. Here is the code with the two different methods.

  

  I feel like this is an operation that would be much better to do it in an if else statement in code and I would like to know if there is a better way to do this in LabVIEW.

  Typical in LabVIEW is to combine Boolean both in a table, then use of the boolean to number table. This will give you a value between 0 and 3 (included). You can use a single case statement, or you can create a table of values of output desired and use it as an index in the table, or if there is a direct mapping of the enum, you can simply convert that number to the enumeration type.

• Reinstallation of HP B210 printer on computer laptop operating system: Windows 7 64-bit

  Hello

  PC:HP Pavilion DV7 Notebook PC Windows 7 Home premium 64-bit SP1

  I also have the problem with reinstalling my HP photosmart B210 (network)...

  I have a few days after the HP Support Assistant update, I lose the possibility of active my scan to PC.

  I have uninstall a SW B210 printer and can't reinstall the computer WIFI connection (using my CD). Can't install USB connection

  With the help of SW PSB210_1315 installation hangs... only info: internal error!

  I have also 2 other PC

  1 8 32-bit windows-based installation of PSB210_1315 without error

  1 Windows XP install PSB210_1315 without error

  I can use my printer for ePrint!

  Intenting CD WIFI connection SW installation using I see my printer with the right address... but always failled connection...

  I used ccleaner to clean my PC also used sfc... no error...

  I think that there is something that does NOT make the connection WIFI from PC to the printer...

  Thanks for any HELP

  Hi gvaneynde,

  If you are successfully able to install this printer on two other computers, which indicates that the printer and software work. It is possible that there is something on this operating system of computers contributing to the failure of the installation. Follow the steps outlined in the document below and let me know if this helps to get the printer installed?

• 32-bit Windows operating system on a 64-bit architecture

  We have a picture of the mother who has been defined as a 64-bit computer when creating. But when it was time for the installation of Windows 7 ISO, a 32-bit version has been installed. We have taken snapshots and reconstructed with this vm parent... performance seems to be great! We had no problems with VMTools and view agent seems very well... is there a reason why we should not do this way? Is this the same as the installation of an operating system to 32 bit on a 64-bit system?

  Whatever you select a guest OS 32-bit or 64-bit operating system, if the physical processor is a 64-bit processor, then the guest virtual processor will be a 64-bit CPU.  (For a CPU virtual 32-bit, you must specify additional configuration option, monitor_control.disable_longmode = TRUE)

  For Windows 7, in particular, I see no problems with your current configuration.  Given the age of Windows 7, which is unlikely to change with future editions of vSphere.  In general, however, it is best to choose the type of guest OS that is similar to the guest OS installed.

• Or logical operator

  Hello
  
  Why there is no way to set or logical restrictions for generic types?
  

  public class MyClass{
      //you can add to this set only integers or strings, at runtime this set contains objects
      private Set<? extends integer || String> mySet;
  }

  Why there is no way to set or logical restrictions for generic types?

  Because there is no way to use the resulting code, unless there is an interface or a common, whereby base class case is what you specify, is why the language gives you only a means to do so.

  Thank you

  In my view, that should be using the oracle VM. So, you need to check that you can use it on windows 7 Home Edition? If can, the models would work too. I can't check right now since I do not use a pc but the phone for this answer, but think it would be easy.

  Hi all
  
  When I select 'Function' in the menu drop-down menu in the drop-down list box operator on the screen of the logical group of FDM 11.1.3, I get the following error:
  
  The operator must be between 1 and 5 characters.
  
  Why this error is coming?
  
  I use a type of simple logical group.
  I created a simple logic account to map to an account only source in my file to the input source.
