• analog multiple read arduino serial communication

  Hello

  I'm working on a project and I'm new to Labview,

  Can someone tell me how to read the multiple analog playback on Labview in communication series with Arduino UNO?

  I tried, but data are somehow in error.

  I have also attached my current code of vi and arduino.

  Please help me.

  Hello

  You then send a value of more than your Arduino project. But in you VI you do not analyze the data entering split of voltage and current.

  I suggest that you send a fixed string with voltgae and data current so that you know in your VI you will receive the number of bytes and how to divide the data.

• 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

• Arduino restarts my PC when it is used for the serial interface

  Hello

  I use the example of continuous series read/write and other simple programs to read data from the Arduino board, but I am facing a problem that my PC restarts wih blue screen when you read data from Arduino for 5 minutes.

  I don't know the reason and tried various solutions, including adding the number of bytes to Serial Port to connect with the VI series of reading.

  Kindly guide me what could be the possible reason for this problem.

  Concerning

  I had this problem too - my PC would crash on average about once a day when connecting an Arduino data.

  Someone on these forums proposed defining the synchronous and not asynchronous read VISA. Right-click in the VISA reading and select ' E/s synchronous Mode' > 'synchronous '.

  I tried this and it seems to have worked - I have not had a crash for about a month now. I have no idea why it would make a difference, but it seems.

• Simulation Serial Monitor of the Arduino with Labview?

  Objective: Simulate Serial Arduino using Labview base series Monitor write and Read.Vi.

  Problem: When a stream of ASCII data is sent to the base series writing and Read.VI it stops playing after about 3 seconds.  Whereas that must be continually read data even when there is more data that can fit in the reading string indicator. Ideally, it should push the old data from the top of the screen and display the data again at the bottom of the screen.

  What changes should I do at the base series write and Read.VI to simulate Serial Monitor of Arduino?

• Cannot write serial Arduino

  Hi guys, I develop a project requiring Labview to interface with Arduino Uno, but no matter how to change the connection, my series write Dungeon works bad, when I click on the button "Home", the Rx led on the Arduino is flashing which indicates having received something, but my gear didn't get no action at all, so guys help me please check if my connection on the pallet of Scripture is correct or not. Thanks in advance!

  They are not your problem, but a few general remarks:

  1. the outter loop and case structure are unnecessary.  Just remove them.  When you run your VI, you will be connected.  This will make things easier to see (less noise).

  2. almost all the code I've seen with an Arduino uses the PrintLn function, which adds a termination character (line break) to the post of series.  I highly recommend you use this, turn on the termination character using LabVIEW code and then get rid of the bytes to the Port.  Suffice to say the VISA readings to read more bytes than the longer message of your Arduino.  Playback stops when they find the line break character.

  3. maybe your problem: the Arduino expects to see a line break at the end of the string it receives?

• 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.

  

• Servos and HC-SR04 in a code (arduino)

  Hi guys,.

  How can we use servos and HC-sr04 in the same code?

  I'm in a situation of catch 22 where I can't use both of them as LINX supports HC-SR04 but no servos, LIFA media servos but not the HC-SR04.

  I am stuggling to make a Subvi pulseIn for this.

  Is there any solution for this?

  It's the easiest way to do it! In fact, the hardest part is written the Arduino for the custom code. From the link I sent you, there's a Subvi, which already exists to invoke the custom command you defined.

  The toolkits Arduino, both work in the same way - you run a firmware pre-compiled on the Arduino which is the interface between the hardware and it speaks to LabVIEW using a protocol series. The Toolbox said, you don't need to write LabVIEW code for the serial Protocol, nor do you need to write the Arduino Sketch yourself. The fact that you can change the sketch to add custom commands is a very powerful feature and saves you more having to write your own sketch (or LabVIEW code) from scratch!

• Waiting for data on serial port

  Hello everyone.

  I'm trying to figure out how I can solve a problem on LabView. I programmed an Arduino board to read and send a data table of the accelerometer on the serial port. I want to LabView to receive the data and graphs it. My problem is that Arduino send data on an ongoing basis and sometimes LabView can not cope with traffic and read some values "0".

  Is it possible to wait for the data and solve this problem?

  I joined my current vi.

  Thank you much in advance.

  AndreasSchnaas wrote:

  Yes, the characters are 0-9 and - no. ' + 'or'. '. And bytes that vary.

  Once again, thank you very much.

  Given that you send ASCII characters, change your Arduino code to send a character to end of line (10 byte value) at the end of each transmission.  Your code is already configured to use it.  Then you need not use the bytes to the Port at all.  Suffice to say the VISA of reading to read a large number of bytes.  Playback stops when it finds the stop character (value 10).  Your code will get a lot easier from there.

• How to read the DHT22 of Arduino

  Hi, I am a beginner and I don't know how you could read a sensor of DHT22 of a Serial USB which is connected to the Arduino and making a certain amount of humidity, the LED light lights up. It is even possible to acquire data of sensor of DHT22 like that?

  I'd be really grateful if you could help me find a basis or example where to start, thanks in advance.

  Communication of the arduino to the pc with LabVIEW is irrelevant to your problem and if you had a problem with this communication, this is always the wrong place to post this kind of question.

• Arduino + LabVIEW

  Hi, I become a fan for LabView... only for a few days, and began to do a project using Arduino.

  I would like to take temperature sensor (LM35) data and show grafically on labview. (Of course the serial communications is used). I went by the examples given in the LabView8.5 but I'm not able to grasp the thing, I'm able to select name (com22) resources and everything, but if I click on reading, nothing is displayed. Before you run the simulation I'm uploading the sketch for transmiting temperature continuousely to analog pin 0 IE. for the series transmission, any body can help?

  I did exactly the same thing as here education project at the University of Toronto. I designed a shield which uses an LM35. I added a few signals conditioning circuits and used 0 analog. I wrote a sketch to convert ASCII text reading and send it on the USB port.

  I already posted my code LabVIEW to acquire and display data from the Arduino. Take a look at this thread:
