Arduino toolkit

Having trouble connecting the ( even running ) the example to read serial data from the arduino toolkit.
It seems that my program cannot see or find the arduino resource. It throws up an 'Error 5002' which basically tells me that it's something with the serial port.
So to check I wrote a simple 'Read Serial' after 'Configure Serial' on the same COM port that I mentioned in the above example & am able to display a buffer string ( without the arduino toolkit ).
What could be the reason? In the example below, I only included the VISA serial read part since I was getting th error. I would obviously not use them concurrently.
Attached some screen shots.

Hi vaishakh.chava,
You're completely correct in saying that LabVIEW is unable to establish a connection to the Arduino microcontroller. There are quite a few reasons as to why this can occur, so it's important to make sure of the following:
Make sure that the correct firmware is flashed to the Arduino. This will configure the microcontroller to understand the communication protocol implemented by the LabVIEW VISA drivers to control the peripheral interface ports. The correct firmware can be found in<LabVIEW>\vi.lib\LabVIEW Interface for Arduino\Firmware\LVIFA_Base
Make sure you have selected the correct COM port for the Init.vi or that the VI automatically locates the Arduino (this happens when no wire is connected to the VISA Resource input of theIniti.viand only works for Arduinos that areconnected to the PC via USB); otherwise the wrong USB port be communicating with.
If using an Arduino connected via USB make sure that the Arduino is listed as under Ports in Windows device manager. If it is not listed you may need to install the Arduino drivers. If the device is not recognised by your Operating System, it will not be associated with your computer due to missing driver calls; this means your Operating System would be missing the means by which to communicate with the device on the most basic level.
If using a wireless connection (Xbee, BlueSMIRF) to LabVIEW try using a wired connection (USB , Serial). Poor wireless signal strength can cause the Arduino to be unreachable by LabVIEW.
Make sure that the baud rate specified as an input to Init.VImatches the baud rate specified in the firmware by the DEFAULTBOARDRATE definition at the beginning of the code. If the wrong board rate is specified, the communication between the devices will always be out of sync and will data will not be correctly 'understood' between VISA and the Arduino.
#define DEFAULTBAUDRATE X (where X is the baud rate).
Please let me know how you get on with these steps!

Arduino Mega Toolkit for LabVIEW 8.5.1

Hi guys,
I need the Arduino Toolkit for LabVIEW 8.5.1.
I'm using the VI Package Manager 2010 but there's no Toolkit listed.
Is there a way to get this Toolkit?
Regards Bartosz.

Hi,
I found this link: How do I Install the LabVIEW Interface for Arduino Toolkit Using VIPM?. as you can see there:"Primary Software Version: 2009 SP1". So I guess the toolkit isn't available for LV8.5.1.
Maybe the Arduino Community can help you.
Kind regards

Using LabView, Arduino, and Easy-Driver to control a Stepper Motor

Hello fair folks of the LabView forums!
I am a humble engineering student in need of some advice and input on a project I am working on.
I’ve also done a fair amount of reading on the LabView forums with people trying to use LabView and Arduino to control stepper motors, and I’ve used as much information from each as I could. However the problem I'm encountering now is one which is unique to my VI Configuration.
So, here is what has been done thus far:
-Installed LabView Interface for Arduino [LIFA]
-Installed necessary VISA drivers for LabView to communicate with arduino
-Uploaded firmware to Arduino to allow it to communicate with LabView
-Properly wired Stepper Motor with Easy Driver and Power Supply; I have verified this by first using the Arduino independently of LabView, using example code found here.
-I have created a VI, and have just recently got it to run without reporting back any errors. While I suspect the behavior I’m encountering has to do with something inside the VI, it is difficult to determine as there are no errors being reported!
But here is general problem I am encountering:
-Connect Joystick to USB Port, connect Arduino to USB Port.
-Plug in outlet for Power Supply
-Open LabView VI
-Run LabView VI
-LabView successfully detects Joystick, and Arduino.
-Tilt Joystick; Stepper Motor moves in proper direction, but it only takes a single step. If held, it does not move further. If returned to zero, and then tilted, it again only takes a single step.
I know that in the example code, the Arduino issued the step command by writing the signal from LOW to HIGH, and varied the speed by how often it did this.
I assumed that the Write-PWM feature would do this same thing, but perhaps my assumption is wrong. I will continue to tinker with this myself, but I would be extremely grateful for any insight you might be able to lend.
I’m thinking, if not the Arduino Write-PMW feature perhaps a simple timing-sequence that could be used to alternate between writing 0 and 1, with the timescale of the sequence being scaled to the X-Axis from the Joystick. But, I am open to suggestions, and certainly appreciate any thoughts you may have to offer!
Attached to this is the VI used in this setup, a picture of said VI, as well as a rough sketch of the hardware configuration.
Thank you!

LabVIEW toolkit for digital still camera - PTP protocol based

Dear List,
Just to let you know that a LabVIeW toolkit for PTP
(picture transfer protocol)camera is available. PTP is
the new standard for still imaging devices such as
still camera and scanner, it does not require camera
vendor extra special drivers (unlike Twain)and it's OS
independant, thus being supported widely in modern
high resolution digital still cameras. Interested
people can check out this link:

Using lab view to control an Arduino led cube

Has anyone used lab view to control an Arduino led cube? It seems to me that you could make a pretty awesome project out of the two.

Hi there, I haven't done it my self but, you may find a tread at the LabVIEW Interface for Arduino Group including links to download the LabVIEW Interface for Arduino Toolkit . I think this will make the task easier. Good luck!

Labview Arduino toolbox & linux

Ciao,
Is it possible to use VIPM 2014 with Labview Run Time Engine 2014?
On a Linux PC I have Labview 2014 installed and would like to use the Labview Arduino Toolkit which seems to be installed via VIPM. On running ./vipm in the apprpriate directory the error below is displayed:
Can't find library liblvrt.so.13.0
Make sure this library is installed in your LD_LIBRARY_PATH
search path, or in /usr/lib
Can the 2014 Labview Run Time Engine be used instead or is it possible to install the Labview Arduino Toolkit manually?
Best regards

Have you looked at the product page and clicked on the Functions tab?

NI DAQ and Arduino in Matlab (control obj in a callback function triggered by another obj)

(I am aware that this may not be the most appropriate place to ask, but I'm pretty desperate...)
I am writing a script to acquire online data from a DAQ card and to control an Arduino microcontroller based on the output of the DAQ card data.
The acquiring of the DAQ card data works fine, but I'm having problems with (1) the online processing of these data and (2) the corresponding controlling of the Arduino microcontroller. I'll try to explain both problems as clear as possible, the matlab code that has already been written can be found at the bottom of this question.
I'm using a 64-bit Matlab, so I can only use the Session-Based Interface.
1) Online processing
Data are collected at a rate of 1000 samples/s. Each time 250 new samples are available, a callback function is triggered to process these data (using a listener triggered by the 'DataAvailable' event). This processing consists of spectral analysis, using the 'spectrogram' function. The problem is that the spectrogram function should use a window of 500 samples and an overlap of 250 samples. So, new samples should be available for processing every 250 samples, but not only the new 250 samples but also the previous 250 samples are needed to accomplish the overlap. Basically, I need 500 samples for each callback function run, but this function has to be ran every 250 samples.
2) Controlling the Arduino
The biggest problem lies in the controlling of the Arduino. After spectral analysis, the calculated value is compared to a predefined treshold and if this value exceeds the treshold, the output of the Arduino should be put to one, else the output should be put to zero. The problem here is that, since the callback function is an external function, it doesn't recognize the Arduino object. The Arduino has been connected to Matlab at the start of the script, but is only available in the 'base' workspace. Connecting the Arduino on each function run isn't a possibility, since this should be done every 250 ms.
Attempted solutions
I have tried to make the function into a nested function, so that it can use the same variables as the ones in the script, but Matlab doesn't allow this. When I write a nested function, I get the following error: "A nested function cannot be defined inside a control statement (if, while, for, switch or try/catch)." However, I have never defined one of these statements, so the function isn't inside a control statement. I don't understand why this doesn't work.
Matlab code
Script
%% Preparing Arduino
% Connecting the arduino chip to Matlab
a=arduino('COM4');
% Defining the 13th pin as an output
a.pinMode(13,'output')
%% Preparing the DAQ card
% Searching the DAQ card
devices = daq.getDevices;
% Create a session
s = daq.createSession('ni');
% Define the input channel
s.addAnalogInputChannel('Dev1', 0, 'Voltage');
% Define the total measuring and stimulation time
s.DurationInSeconds = 4;
% Define the interval for processing
s.NotifyWhenDataAvailableExceeds = 500;
% Loading the optimal stimulation parameters
load('parameters.mat')
setappdata(s,'freq',parameters(1))
setappdata(s,'treshold',parameters(2))
% Define a listener triggered by the DataAvailable event
lh = s.addlistener('DataAvailable',@stimulation);
% Save the start time
starttime=clock;
% Start the measurements
LFP=s.startForeground;
Callback function
function stimulation(src,event)
freq=getappdata(src,'freq');
treshold=getappdata(src,'treshold');
LFP=event.Data;
[S,F,T,P]=spectrogram(LFP,500,250,[],1000);
PSD=log(P(freq));
if PSD>=treshold
a.digitalWrite(13,1)
else
a.digitalWrite(13,0)
end
end
All comments/suggestions are welcome.
Many thanks in advance!

Hello hemm,
As you noted this is most likely not the appropriate place to past these non-NI Development environment related questions.
Especially since the issue does not seem to be related to the interface with the NI DAQ card.
Maybe you could add some Message Tags so that people that are following specific tags might be able to detect your question and help you.
Would it be an option for you to use NI LabVIEW?
If this is the case then it might be interesting to note that many of the Arduino users over here are using the NI LabVIEW Interface for Arduino Toolkit:
http://sine.ni.com/nips/cds/view/p/lang/en/nid/212478
This is however being supported from the following page:

How do I stop VI Package Manager from crashing when I try to use it?

So I've been wanting to play around with the Arduino toolkit, but when I installed the VI Package Manager, the splash screen stayed up for a very long time. I tried quitting in Task Manager, and running it again. This time after about 10 seconds, it gave me the standard Windows crash dialog. I tried running it as Administrator, but that didn't help. I also tried running it in XP compatibility mode, and that opened a popup saying it couldn't detect a LabVIEW installation, but it still wouldn't load (It didn't crash though; just stayed at the splash screen.) I'm running Windows 7 Ultimate, and LabVIEW 2011 Professional Development System.

You really should ask this question on the VIPM board at JKI.

Calibration

Hi. I'm new to labview 2011, and I need to calubrate a power meter. I am using an arduino and the Labview Interface for Arduino toolkit to aqcuire the data, then manipuylating it to get voltage, current and calculating power. How would I go about calibrating this? All I want to do is have it Correct the offset if there is any if a button is pressed. I have absolutely no idea how to do this or what I am doing for that matter. I am attatching a copy of the labview code I have so far. This works to my specs, but I just need to incoorperate a calibration algorythm in it. Thank you in advance.

It may easier for you to use a state machine. There are lots of examples here on the forums. This is something to get you started. Basically you would have the following states: run, calibrate, wait disconnect, wait connect, get volts, get current, etc. Using a state machine makes it easy for you to do something like veryfy the battery is disconnected when the user says it is. (Of course don't do that if it is not part of your requirements - I'm just using this as an example)
To get user input you can use the prompt user for input express VI. I personally would use a subVI set to run as a dialog under File/VI Properties/Window Appearance. But the express VI might be quicker.

Xbee data extracting and graphing

Hi,
I have been trying for a few days to get this to work with no results. I have searched through google and some of the forums for help with nothing that really helped.
I am using two xbee devices to transfer data to labview to graph.Eventually I would like to use the ADC on the Xbee to take an analog signal and convert it to a digital signal for labview to read and so I can do my analysis on it. I started with getting a basic Visa program to work and send number from my arduino uno over and over again and placing those values into an array This works great with no problems. The problem comes when I try and send a signal through the Xbee.
I tried to send an analog signal out to the adc and I was getting some values in labview in Hex but I was unsure what they really meant. My second attemp was just to try and create a pulse wave using my arduino and send that to labview and have labview try and graph the incoming signal. This however did not work and I am not getting any data. I connected both Xbees up on a bread board without labview to see if I can get the a signal out of the recieving xbee and it worked. So the problem should not be with my xbee's but with my code.
The code is where I am not sure about. I was able to find examples of how to use the visa and was given a basic example of it. I have then tried to manipulate the program to see if ti would work for me. I am trying to take the signal from the VISA Read funciton and convert it to a 1d array to display on a graph. I have also tried to seperate the dat into an array char by char from the string. However, none of this worked. I am getting a zero value out for my graph and no values into my array. I am also getting no value into my READ String area.
The values I have sometimes gotten look like:
00\00\00\00\00\94\00\00\ and so on with different value. Some time the byte read is very large up to 475 when I am placing the pulse wave in or so and sometimes smaller at 19 when I tried to connect the ADC.
I have attached some of my VI's to see if anyone can come up with a better way or point me in a better direction.
The png is a pic of the results I got from the pulse input. So it looks like I am not getting any data at all.
Thanks for the help

Moving a library guidance

Hello all,
I am not exactly sure what I am looking for, but I'm hoping someone can point me in the right direction.
I downloaded the LIFA (Labview Interface For Arduino) toolkit through VIPM on computer A. I then modified the toolkit to communicate to an Arduino via Ethernet instead of Serial along with creating some custom VI's which I believe are in the LIFA library. I now need to get that library to computer B.
Whenever I try to create a new library and add the files and folders to it, the entire LIFA library is copied over with it. Basically, my new library looks something like this:
-New Library
-LIFA
+Subfolder
+Subfolder
+Subfolder
+Subfolder
I've seen topics on creating a new Library from an existing one. Is that what I'm looking for? If so, can I just create a new library and then copy and paste it into the vi.lib folder on computer B?
Thanks,
Matt

Here is my end game, I am developing a VI which controls the Arduino through ethernet communications which I will distribute to my clients as needed. Once the code works for me, I'd like to realease my LIFA-Enet library to the NI/LIFA community along with giving the library to my clients, so they can modify the top level VI's as they see fit.
I think Sorce Code Control is to have multiple developers working on the same project, correct? I haven't looked too far into it, but if its what I'm looking for, I'm not opposed to it.
Matt
Edit:
I am the only person that is working to develope code (that i know of) for LIFA-Enet. Therefore, I feel like subversion would be excess if I'm the only one checking things in and out through the Sorce Control (which sounds like subversion to me).
I use SVN at home for my projects that I am the single developer. Even for a single person source code control is useful. It allows you to maintain older copies of your code so if you really screw something up you can always go back to an earlier version. Tagging the code in the SVN repository is very useful for this.
As for distributing it to your clients have considered using packed project libraies? This would package everything up into a single file and make it very easy to distribute.

Followed LabView toolkit for Arduino instructions but still not working

Hey everyone,
I'm an undergrad working on a research project and we are trying to use the Arduino UNO to get real time data from an experiment we are conducting. I have installed labview 2011, NI-VISA and Arduino 1.0.1 following the instructions for the setup. I loaded the firmware to the arduino and the send/receive lights on the arduino flashed when I ran the program, however, when I attempted to change the LED status from on to off (LED example) there was no response from the LED. I did not receive any communication errors so I'm not sure what is the problem. I checked the Measurements and Automation and it recognizes the board and I checked to make sure the baud rates matched. Still no luck. Any ideas would be greatly appreciated.

You'll probably have better luck getting help with this issue if you go to ni.com/arduino and click on the discussion tab. Most customers and NI employees who use work with the Arduino post on that discussion board. In addition, ni.com/arduino has a lot of useful information that you might find helpful.
