Pilot NI VISAS for Arduino Uno R3 configuration problem

• LabVIEW arduino uno bad data transfer

  Hello

  I have some problems with the transfer of data from the arduino uno to labview.

  I did a VI where I can control the power of a heater with measurements of temperature with arduino uno.

  The problem is that from time to time the incorrect temperature is captured in labview by missing the number or a number, for example. LabVIEW gets 1.25 ° C instead of 15.25 ° C or 2000 ° C instead of 20.00.

  When I look at the program arduino tracer series these errors do not occur. So I guess it will be a problem with the settings of labview or my VI.

  Parts joined a set of data extracted from the VI and VI himself and the arduino script

  Yes.  The Subvi has 2 major problems.

  The first is as I said.  You set up and close the serial port each iteration.  There is a risk that the device could be send data that you won't miss the moment, that the port is closed.  (Even if she doesn't really explain why you miss the decimal point in the middle of the data bytes.  Serial ports must be configured and opened when the program starts.  Writing and reading within the loop.  And not closed when the program ends.

  The second major problem.  Why you have the property Bits of data cable up to the number of bytes to read.  Bytes and pieces is two different entities.  And in this case, the data bits is the number of bits of data defined by the configuration of the serial port.  Probably 8 and would still be 8 and has nothing to do with the number of bytes actually in the serial port.  Number of bytes to read is how many bytes you want to actually read the serial port, could be 1, 50, 1000,...

  Is your device send data continuously without asking?  Should I use a stop character?  If this isn't, by using a stop as a return character, carriage or line break, then it should.  It will help you to break the ASCII data that crosses into packets.  Configure your serial port is set up to search for characters of endpoint and it would be a line break character. Use the termination character, and tells your VISA read an arbitrarily large number.  A number that is larger than the longest message that you expect to receive.  The VISA read will return as soon as she sees the character of judgment and you give a full data package.

  It is often a good idea to have a communication protocol of request/response with your device.  You write a command that says 'give me the value.  It reads and responds to the back and gives value.  Otherwise if he sends just data continuously without asking confirmation and that you do not read fast enough, you could extend your serial port (which would give an error and you could lose data), and even before that, you could read old data which is at the front of your stamp series while your device has already sent hundreds of data points more after that.

• Arduino Uno + Labview 8.5

  Hello

  I am trying to send commands to the Arduino Uno using Labview 8.5. Tried setting basic series writing and Read.vi the baud rate 9600 and rest of the default parameter, selected the correct COM port and wrote the command

  i5000\r\n

  This command is to rotate a plate of rotation using a motor, 5 degrees. There is no response.

  I can run this command by using NOR-MAX and the Arduino terminal and the motor move.

  Could someone please tell me what am I doing wrong? I had done my own vi using VISA initially, but it didn't work so I tried the example of OR. Is the example for a reason any not applicable to my case?

  There is no error but the motor does not move.

  Thank you very much..

  
  

• Arduino uno error 5002

  Hey,.

  I'm using labview 2011, lifa 2.2.079, arduino uno rev3 connected via usb to the pc

  If I open Device Manager I find under ports: arduino uno (com3)

  also if I open or max, devices and interfaces in series and parallel I find com3 when I click it I find in the device status area: this device does not work correctly

  I also checked my Arduino board using the arduino software, I tried to download the example of Flash and it works if this isn't a hardware problem

  but when I am trying to build all vi (I tried one which turn on and off the led to pin 13) or by using any instance in the for example the analog player lifa vi I get error 5002 and nothing works...

  I checked baud rate and I tried to increase the timeouts and I created a constant for VISA resource choose com3 in the init.vi (all these are solutions found in other discussions here in the forum) and nothing worked I still get the error

  can someone help me in this?

  Thank you very much

  Download the 1.0.5.then from the arduino between software software, click on file > open... > c hard drivefor example) > program files > instruments > labview > vi.lib > labview national interface for arduino > firmware > lifa_base > lifa_base. then download the file on your chip, close the software, enter labview and run your vi It should work. If you do not understand, you can follow the steps mentioned in a youtube video... Enter youtube.com > labview arduino... Watch the first video that appears.

• Problem with Labview communication with Arduino Uno

  Hello

  I tried to run a simple program in labview through my Arduino Uno R3 all morning and keep running into the same problem: no response from my Board of Directors. I'll catch you up on what I've done so far:

  -flashed LIFA Base to my Arduino
  -Downloaded the driver update of VISA

  written-a the block diagram (I hope) for a led on off function

  When I run the program in labview, the RX flashing intermittent, continue for 30 seconds before stopping. The led on pin 13 is not turned off as it should, and I have no control over the power function light. I also tried a program of control of servo with no response and the same flash of RX. Never the TX flashes.

  I am quite stuck, so any help is greatly appreciated. Also I'm not a comp sci guy, I'm just an engineer in mechanics with a half of C++ so keep pg when it comes to the language of the computer.

  I've attached a picture of my diagram of LED, see if you can spot a problem.

  Thanks in advance!

  SOLVED: Reset the Arduino card after that labview had sent his orders (while the RX light was still flashing). Works like a charm.

• Timed signal generation TTL with the NI USB-6501 to be read by Arduino Uno

  First of all, I want to apologize - I am very, very new to LabVIEW and brand new to the development of the software of control equipment in general. I tried to find an answer to this question already, but I'm not entirely sure what I'm looking for.

  I have currently a work program LabVIEW which operates a gun card NI USB-6501. Due to the nature of having a machine that springs from a powerful beam of electrons, we want to assure you that if the computer controlling stalls or fails for any reason, we have built-in security that can stop the gun. Our current idea is to connect an Arduino Uno on a PIN on the USB-6501 and LabVIEW to generate a timed signal, which may read the Arduino. If the signal fails (indicating that the control computer has queued or off), the Arduino triggers a power relay that is independent of the control computer and turns off the gun.

  I understand that the USB-6501 operates on TTL signals, so the signal that I should be something in the sense of "output TTL high, wait 1 second, output low expectations, a second, repeat TTL ', but I have no idea how to go about programming in LabVIEW. My first thought was that it is a square wave by using the function "simulate the signal" output, or to have trigger an iterative Boolean signal, by using the function 'DAQmx write', but I don't really understand how do to implement or another idea, or if an idea would even work.

  Any advice would be greatly appreciated.

  Hi Elizabeth,.

  THINK THE STREAM!

  When do you DATAFLOW think everything falls in places!

  Several problems:

  -You have to put that MAKE impulse VI in his own loop parallel to your main VI!

  -When you place this generation of impulses in the effects loop ("TTL arduino low-high") you should put the CreateTask and StopTask outside the loop: no need to create/stop the task in each iteration.

  -Why are there points of constraint to waiting functions?

  -Why is there bent wires? You know Ctrl-U?

  -LabVIEW comes with an extensive library of example screws: you looked at all these examples DAQmx?

  -Suggestion: Learn more about the "structures of producer-consumer"!

• Pilot NI VISA - problems of driver installation wizard

  Hello

  I generated a pilot with communication as to the NI VISA driver with a USB - HID Device Wizard. Driver and LabVIEW Application work fine - on the development system (Windows 7 x 64).

  Now, I want to move the application compiled to another PC, using the same operating system (Windows 7 x 64). I tried to install the generated driver by clicking on the inf file and choose install. After that, I will ask if I want to install the driver, which I agree. The installation process runs, but in the end, the device is not visible in the Device Manager.

  So I went in the development system and uninstalling the driver real. Now, I did the same steps as above (right-click inf-> install->...). Same problem, the device is not visible in the Device Manager.

  Now, I went back to the pilot NI VISA Wizard. With it, I am able to install the driver.

  How could install an inf generated on a system without a VISA NEITHER pilot Assistant?

  Thank you very much.

  Best regards

  Michael

  Hi Michael,

  OK, I thought he should there have generated one or more other files which can be transferred to another machine and that should be installed with the inf file.

  I did some research and discovered things about the problem. Please go through the links below and see is they solve your problem:

• LabVIEW VIs for HP 35670 has

  The link to the labview for HP 35670 A screw is no longer valid and the same search returns nothing.  Does anyone have the Labview VIs for this instrument?

  The last message is in 2004 (see below)

  The instrument for the HP 35670 A driver is only
  supported under LabVIEW 6 and 7. You need to upgrade to the latest
  version of LabVIEW to use the HP 35670 A driver or the
  drivers newer than we release in the future.

  The instrument
  Driver for HP 35670 A can be found on our website at

  Why don't you go to the Instrument Driver Network? I don't know what kind of research did you, but the driver is still available and can be found by using the search option here.

• Possible security for the Web-based Configuration

  My colleagues and I found something very interesting today... Despite having configured the FTP security settings (which have been confirmed to set up and in funcitoning. I can't open an FTP session to our remote target without specifying a username admin and the password) If you open the configuration tool based OR web in a browser, you can send via FTP to and from the target using the file remote browser without being connected to all! Everyone knows this?

  Apparently, these permissions are separate from FTP, but you can define these special permissions on the page of the security configuration for the web-based configuration utility.

• visa for brooks 0154 driver

  Hello

  I'm looking for a driver for Visa for 0154 Brooks. I can even connect to the Rs232, with their program dde 'smart '!

  It seems to be a visa driver for Hart, but for the MFC 5850 not for the 0154 controller. I don't want to control four MFC but just a 0154 controller which will deal with the MFC four attached to it.

  Thanks for any help

  Brooks 0154 controller requires a null modem for RS232 communication. Brooks has a Labview VI for the 0154

  can be used to control the MFC5850. The labview VI can be used with the 0154 for controller control MFC 4.

• Is there an option for a default application configuration in weblogic?

  Hi guys,.
  
  I have an application deployed on a server admin.
  
  I access my http://localhost:7001 app / browsestore
  
  I want to access the application only if I enter http://localhost:7001 in the address bar
  
  Is there an option for a default application configuration?
  
  Thanks in advance :)

  Hello

  OPTION - 1).
  Assign the value of the 'context root' as element.
  It will make your WebApplication a default web on the server application...
  To change the root of context in weblogic.xml next entry is necessary:
  Example:
  
  
  /
  

  OPTION - 2).
  If you do not want to change your "weblogic.xml" and then log in to the admin console-
  Servers---> YourManagedServerName (Click)---> Protocol (tab)---> Http (sub-tab)---> the default Web application context root:

  NOTE: -.
  In the field above, please specify your root context WebApplications that precedes a slash (example: /MyContextRoot)...sothat after the restart of the server the Application will become your default WebApp servers...)

• Windows configuration problem on Aspire M

  If anyone on the forum has experienced the following? My Aspire M displays the following message after trying to download windows updates: "configuration of the Windows updates failed. Restoration of the changes. Do not turn off your computer.

  For about 30 minutes, the co0mputer is in this mode to 'come back' and I have to just sit there and wait that it happen by itsexercise. Most frustrating!

  This has happened for at least 8 months now and to the extent where nothing I tried helped. Windows recognizes that it is caused by a problem of Windows software, but did not come with a fix!

  I hope someone can help?

  Hi GuruAid - CS and Acer supports,

  Thanks a lot to you two for your answer to my problem. The response from the Acer Support where for me first and I did not lose any time, applied the suggested steps. Support Acer mail 14/10 got to me and I waited my answer for the following reasons:

  As I mentioned in my original post, this problem has been with me for a while in which I had some Tech Guy (3) looking at my PC and the 'fixing' of the problem. Two days later he was back again. This was the case in all three fixing operations. If I didn't like my Acer Aspire so, that would have been when I was ready to buy a new computer. But, as I said, I am satisfied with the machine - it is the fastest and most powerful I got sofar and I bought my first PC in 1996 - and was reluctant to "abandon ship."

  I can an episode with Microsft. About5 weeks I contacted Microsoft technical support and has been in contact with one of their technical support people. Apparently they charge for this service and they demanded $99 for it. When they took the number and my name on my credit card down, they made a small error in the spelling of my last name. I pointed out to them, but Visa had already pulled the plug on this transaction attempt and had cancelled the card at a time. I had to get a new credit card and did not attempt to communicate with Windows again.

  I finally thought to this forum and only wish I thought of it earlier. Since 14/10 I had NO recurrence of this problem!

  After having so many false hopes, I hesitated to write after a few days the problem has been resolved. I got at least 30 starts and stops since then and there is no problem. After following the instructions Acer supports. I do, however, I keep GuruAids suggests measures on hand - just in case :-))

  So, thank you again for your excellent advice and quick help. I can't get the smile off my face :-)))

  Best regards

• Configuration problem?

  I'm new to Labview. I can't connect with 3458A. It works with 34401. I use a USB/GPIB from Agilent 82357 B interface. I have a VEE program that works with the 3458A. I think I have a driver or configuration problem. I am at a total loss, any help would be appreciated.

  I got it to work with the correct command. Thanks for your help. I have much better understand how this works now.
