• Problems with arduino labview Interface

  I have the labview-arduino interface, but the problems came when I run the program, sometimes it work perfectly, but sometimes (almost all the time), I can not connect this time, the series of programs and do not show any kind of problems, I can see that in the resourse computers two visa, I don't know if it's because she I soppose comunication , but my arduino do not work, and I can use perfectly with the arduino IDE, but not with VISA, I used the Arduino IDE to be shure that works my Arduino board

  so if you know how to solve this problem, please help me!

  Thank you!

  There is no need to host files somewhere else.  Feel free to download on the forums and attach them to your message.

  Minor first comments.  Why are you re-reading your every 2 seconds config file?  Expect you to change?  If it is then played once and not proofread.

  I think it would be better if you stopped when an error occurred, you can do this by wiring to the RO error enter the stop condition, or use the arithmatic composed with gold.

  But I think the main question you have, it's that your Arduino reference may be whipped out if you do the wrong things.  If your equal comparison is false, you go to the wrong case, where you are not passing the arduino reference.  So when you go to close you don't close your reference and your equipment will always be open, and you try to run again will result in an error.  For even if your loop runs for 0 iterations your reference is lost.  An updated version, which has some of these changes is attached.

• Arduino/LabVIEW input acquisition and control engines step by step at the same time

  Hey, I'm doing my last year of electronic engineering project and I'm trying to control 2 Motors step by step with labVIEW. A microphone will be placed on a platform that the stepper motor control and adjusts the position of the platform according to noise levels read from the microphone. To control stepper motors, I use 2 controllers engines step by step Sparkfun.com.

  https://www.SparkFun.com/products/10267

  These controller requires input of pulse. I'll use a DAQ 6008, but I don't know if this can produce a pulse? I also thought using the Arduino to control stepper motors that work perfectly with the controllers, but it would be able to order the engines while gaining an analog voltage to the microphone?

  I appreciate any help you can give.

  But you can use LabVIEW to work with the Arduino using the tools described here http://sine.ni.com/nips/cds/view/p/lang/en/nid/209835

• Arduino, labview with DAC

  Hello

  of this program is reading and to generate an analogue signal, pour it, but an analog digital converter of 8 bits is necessary "DAC0800", this last do the conversion remains at its output a negative current.

  UN connected operational "LM358" will transform the negative current to a positive voltage.

  When I measure the voltage at the exit of OPAMP by a multimeter the voltage varies in a way ordered 2 to about 4 volts.

  but when I use the arduino to measure the analogue voltage, the voltage varies in a disorderly way, why I don't know! the of is what program is right!

  Please help me.

  The converter, the connection, the code.

  Remember that a dmm will take multiple readings and average/filter before displaying a measure. Do you do none of this c code before sending data?

• Thank you for existing!

  I used LabView for the first time 3 months ago. I come from a background in C++, so I had the programming concepts but was often confused by the new environment. The community here was both an excellent resource and often had me laughing uncontrollably hard enough to forget my colleagues!   (See the LV proverbs hereand more recently here. This thread makes me always laugh )

  I don't know if I'll be able to use LV in the future, but I hope that I can. It's pretty neat! I kudoed Altenbach poston licensed as a hobby, but I guess I can only cross my fingers and wait.

  So in short, Bravo thank you for existing!

• VISA, read and write checks are block after there is no more lines to read

  Hi all

  I am developing a communication continuum between a microcontroller Arduino Uno and LabView. The issue I'm having is to 'Write' and even 'Stop' controls are block once all the initial reading lines are read in. I'm pretty sure that this is because the reading line prevents the complete completetion of the while loop, suspending all the loop until it indicates something else. I tried a number of Boolean operations and I can't work around the problem. The code itself needs a way to detect has nothing to read and ignore the read statement and continue a loop until the user activates the "write" command and writes something. The read command would have would be to read and wait again for user input.

  Any suggestions and help would be great! Thank you!

  * Note that I was using labview for all of 2 weeks. I'm getting used to it but I'm not a pro for sure.

  Also, I would like to give credit to physicslight @ https://physicslight.wordpress.com/2014/07/14/arduino-labview-serial-write-read/ for provide an arduino auto detect sub vi for easy then to initialize the VISA controls

  Seems I solved my problem. Using the Instr:Bytes function of the Port, the reading error is fixed. Addition of a few cases to see entry written and that it is received and a delay just incase seems to have fixed my code! If anyone has a similar question see my attached code

• Very long time tasks relay

  Dear friends

  I would like to do a test search to simulate a month of rain and Sun.

  For this I'll use 2 relays, wave of open water for the rain and the other for heating (Sun).

  The student has the time which rained and the days that has som Sun for a month.

  I am thinking of teel the student to transform this month in a few minutes and give me a table with the Ant stop start within minutes of rain and Sun.

  Then, with a clock, I'll compare with the fact that the values of openness and closure of the relays. I use a usb NI 6009.

  People of the forum have a simple way to do this? The problem is that it is not cyclical. So I need to enter starts and stops for rain and Sun.

  I thanks for any help to help me simplify.

  Hi Cross

  I've adapted an example tha I found and appears to be what I want. I must add to the cycles of the Sun.

  do you think it works for a month?

  On the "apparently very new to LabVIEW", I would like that you could please understand I do a lot of things in labview (adaptation of examples, leaning new thigs etc...), but my work is in the search box and it is a new project that I will use the NI6009.

  Now I'm fihish (with the help of Nathan) an xy table of an old tracer to measure the texture of the soil, and right now, I use the shield of arduino + labview

  A few months ago, I need to learn to work with a datataker data recorder, another way to program.

  Several times I use arduinos for small applications, another programming language

  Hoppe, you can understand that every year we have many students with different projects and we must improvise to make each of them. Sometimes we use labview sometimes not. (I prefer because we have a few Renault of OR), but labview is not only the tool that I need every day, I need the knowledge of electronics, I need the knowledge of mechanics, because we always do that have never done before and we need to improvise. and of course we have the money we pay an electronic engineer, an expert of Labview, etc, etc...

  I am a Civil Engineer and to serve the best I can my students I nedd people like you every day.

  Sorry for that

• How to read the Serial Arduino data using labview VISA?

  Hi =). Im a beginner work reading data series from an arduino but im facing... Lets do it step by step

  I built a voltage divider circuit which gives from output
  from 0 to 5V. The output of this circuit is sent to a 0 analog input pin
  of a Committee of Arduino Duemilanove.

  (1) Firstly, I connected the cable to connect to my laptop USB the Arduino.

  (2) I went to start-> control
  Control Panel-> system-> hardware-> Device Manager. Check the Ports (COM
  & LPT). In my laptop I can see USB Serial Port (COM4). Now I know only in
  LabVIEW that I must read the data series COM 4.

  (3) to the side of the arduino, here's the code to read changes in voltage
  entered to analog pin 0. The last line of 'delay' determines the sampling
  Rate of how we want to taste the output of the voltage divider:

  int potPin = 0;    Select the input pin for the output of the voltage divider
  int val = 0;       variable to store the value from the probe

  void setup()
  {
  Serial.begin(9600) (9600);    Opens the serial port, establishes the rate of 9600 bps data
  }

  void loop() {}
  Val = analogRead (potPin); read the value of the voltage divider
  Serial.println (Val);
  Delay (10);
  }

  I slightly modified the basis series reading writing VI... I have
  attached the block schema used with comments. Basically, I tried to read
  data series, divide by 1023 and multiply by 5 to graphic voltage
  variations of the voltage divider circuit.  But Im not getting
  the correct voltage output values. The value of the tension just keeps go
  0 and coming again, as shown in the photo.

  Could you guys please guide me on what went wrong?

  Thank you!

  -you read the data, even if there is no data on the port. If 0 bytes are read => «»

  -in the case of false, you resources VISA wired for the output of channel tunnel?

  -There is no close VISA at the end of the VI resources

  -you're not a loop this VI reading bytes

  I added an addaption of your VI that you should give a try maybe

• VISA reading significantly slows down to 20 Hz (Labview, Arduino + Xbee project)

  Hello

  I am quite new to Labview and Arduino, so I apologize if I use the incorrect terms. I'm having some trouble with the next project, I hope that you guys can give me some advice!
  I have 16 sensors connected to the 16 analog pins on an Arduino mega Board. This Council has a shield mounted upon him, with a Xbee module wireless. I have another Xbee module that communicates with him and it is mounted on a USB dongle that plugs into a PC with Labview 2015.

  The A/D analog Arduino pin output is read and sent every 50ms to the Xbee module connected to the PC. So every 50ms (that is, a frequency of 20 Hz), a new line of analog readings by commas is sent, using AnalogRead and Serialprint in the Arduino. These data are fed to a Labview code with architecture of producer-consumer. Copy the following code configures a serial port of VISA, reads the data, it converts a voltage value and writes the data to a text file (see block_diagram.jpg).

  The problem is that at a frequency of 20 Hz (with the configuration of the attached jpg) when you reach 400 treatment iterations the code slows down considerably and values are not parsed correctly. It behaves as if the queue is full (but the queue of elements indicators show 0) or memory or the buffers were full. It seems quite surprising to me given that the sampling rate is so slow. I tried a few configurations setting the buffer size, empty the buffer by using the queue time, but nothing seemed to work. Is it because the processor loop takes too much time to iterate? I tried to disable data analysis, conversion of voltage and the generation of text file, just keep reading and still have the same behavior.

  This may be the cause? Suggestions to change the block diagram are welcome! Is there a better way to do this than with VISA or queues...?

  I use Labview 2015 on Windows 7.

  Thank you!!

  You think along the good things. But the big problem I see here is that you have a table growing up to stop the program.  You must move the file writing to be inside the loop of your consumption.  This will eliminate the need to constantly develop your table in the shift register, with tons of memory and causing copies of memory (which is very expensive).

  The other concern I have is the speed at which data is available.  If you have a baud rate 9600, then in the 50ms debit you can pass 48 bytes.  This leaves 3 bytes per sample, including the comma.  If you have a debit 115 200 baud baudrate, it turns into 576 bytes, you can send the 50ms.  So the lesson here is to make sure that you use a transmission speed which is fast enough to handle the data that you want to send.

• you want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. A

  I want to send data using labVIEW to arduino using write visa and the process and to take action using arduino. After that, I want to arduino to send out necessary via a serial port to labVIEW which should be read using visa read and store in a chain. While I am able to write or read both individually, I can't do it consecutively. I used advanced read and write vi for checking my code, but nothing is helping. The wrong bed 'time delay before execution. " Please let me know where I can go wrong. Also is it possible to write code for hx711 using labVIEW

  1. you need not "\n" on your orders println().  This command adds an end of line character already in the message.

  2. you get the error because you have a loop around your reading.  After the first reading (well technically, the second because of you add an extra line end character), there is nothing left in the port.  As a result, you will get the timeout.

  3. you should really consider using a Structure of the event.  This way you just don't write and read when you press the Write button and you can also use the structure of the event to make the loop to stop.  I also go up to close the port inside the stop-> value Change event.

  

• 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..

• LabVIEW, arduino y blueto

  Buenas, Estoy intentando realize Comunicación con labview bluethoot y arduino, uso UN programa that works cuando esta mediante el USB conectado,.

  ago di alta el arduino in the computadora me da 2 puertos com In el Vi.ini the pongo q h. con bluemirf algo asi, 9600 blueto not baud rate y intento con ambos COM pero no works, arduino con esta el knew fuente externa USB cable, con el programa LIFA cargado sin y el diagrama del bluethoot use're este.

  

  could fits what tengo q hacer o alguien me falta?

  o If alguien me can pasar a programa than h. Quebec long solo UN led o algo para comparar en as ando evil.

  I did a little research on the LIFA firmware and:

  If you installed labview for arduino interface you should find it under C:\Program NIUninstaller Instruments\LabVIEW (your version number)\vi.lib\LabVIEW Interface for Arduino\Firmware\LIFA_Base\LabVIEWInterface

  On this folder, open LabVIEWInterface.h with Arduino IDE

  find this:

  "

  #if defined (__AVR_ATmega1280__) | defined (__AVR_ATmega2560__)

  #define DEFAULTBAUDRATE 9600 / / sets the default series transmission speed (it should match to the specified baud rate in LabVIEW)
  #else
  #define DEFAULTBAUDRATE 115200

  "

  change to this:

  "

  #if defined (__AVR_ATmega1280__) | defined (__AVR_ATmega2560__)

  #define DEFAULTBAUDRATE 9600 / / sets the default series transmission speed (it should match to the specified baud rate in LabVIEW)
  #else
  #define DEFAULTBAUDRATE 9600

  "

  In the code it said essentially that default baud rate is 115200, if you are not using the Arduino Mega.

  You just need to change the code so default baud rate set to 9600

  I hope that you can get there.
