Interfacing arduino PCI into labview

Good afternoon NI community. Has anyone had the opportunity or requirements to interface an Arduino programmable card into one of your LabView test processes? We are exploring this option because we need to "control" the voltage from a DC power supply that illuminates our LED light panels. This will allow us to progammatically set the light intensity instead of doing it manually. Thanks everyone for your input/

Do you know what an Arduino is? How does this apply to a PCI?

Labview interface arduino

Hi, I am using Arduino with LabVIEW to automate an extruder machine for my masters project. Can you please tell me how to obtain wire diagram for the Arduino circuit after completing the graphical circuit in LabVIEW? Can I get some more examples on LabVIEW interface Arduino related to motion control and automation?
Thanks & regards,

Hello Askhu,
LabVIEW plus Arduino sounds like a fun combination!
SparkFun even sells a kit for it, which is handy because they also provide a good starting point for a support community:
https://www.sparkfun.com/products/10812
And we sell an interface toolkit that may be helpful:
http://sine.ni.com/nips/cds/view/p/lang/en/nid/212478
And our own community page appears to start here:

I don't know much about any of this, but these seem like good places to start looking for more information!
Good luck,
Edwin!

Arduino signal to Labview

Hello! I'm trying to transmit signal of current sensor acs712 reading from Arduino Yun to LabView, but I'm unable to establish the communication through USB port.. I've followed directly from this tutorial: https://www.youtube.com/watch?v=OWCsaR-oOr8 but I don't get any signals or reading..
Do I need some arduino codes before I can establish the connection ?
Really appreciate if you guys can help/guide me step by step! Thank you!

There are a couple of prefab libraries for communication between Arduinos and LabView, LIFA and LINX. LIFA is deprecated at this point, so you should use LINX. In both cases, the library consists of a sketch which runs on the Arduino and some LabView code. The Arduino side of things is a loop that listens for commands/queries from LabView and returns responses.
You do have to interface that current sensor with the Arduino. Since its output is just an analog voltage, that's pretty straightforward; just run the output into one of the analog inputs of the Arduino and use the Analog Voltage Read VI in LINX.

How do I install instrument drivers contained in LLB into Labview 8.6?

I downloaded a third party Labview driver for a temperature chamber (Watlow) and unzipped it to find it had an LLB library. I can access all the VIs through the LLB manager, but how can I take those VIs and import them into Labview so that I can then find them in my I/O instrument control Palette? Since these VIs are in an LLB, I don't know how to take them out of there and put them into labview 8.6. Any suggestions will be very much appreciated.
Thanks and regards,

Hi,
I am trying to use a Diolan DL2-N USB to I2C/SPI/GPIO adapter (https://diolan.com/dln2). This manufacrures provides Labview drivers for the board as well as example VIs. I just want to use them to access to all interfaces via Labview. After that I will design a test setup for our last product line using this adapter board.
What i did:
1) Fresh install of Labview 2014 (evaluaton version). System: DELL Precision M6800 (i7) , Windows 7 Professional SP1.
2) Install NI VISA drivers and NI-488.2 drivers (14.0).
3) Install manufacturer drivers as explained in the link given in this thread.
4) Run Labview. As said, I can see instrument driver VIs under the Function Palette and run example VIs.
5) Run NI MAX. No USB ports listed. Only COM1 and LPT1 (printer port).
6) I ran some windows test apps provided by the manufacturer to access to all the interfaces of the NXP microcontroller in the DLN2. Everything works. I can read analog/digital inputs, force digital out values and use the SPI and I2C (I see the SPI/I2C frame sin a scope).
I have spent one day seeing different links in NI website (have seen almost every demo video on the site) and still are not able to guess why Labview can't see my USB device.
Any hint?

Jose

Reading controller data into LabVIEW through serial connections to controllers?

I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections. Has anyone done something similar?
I see interfacing with the serial controllers as the biggest obstacle and although not directly related to LabVIEW programming, I'm hoping someone here can give me some advice or resources on how best to do so now days.
My first thought is to write a program with VB or C++ to act as a terminal and write the data to a text file for LabVIEW to poll. Aside from using Telix decades ago to work with BBSes, my only other serial experience consists of interfacing with a Kiethly multimeter using a C++ program.
I would rather not use multiple PCs but I have never worked with more than one serial port on a computer before in the past. Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)?
Any info would be great.
Regards,
Dave

Thanks Dennis.
I spoke with Envirotronics and they do not provide the driver for the System Plus controller any longer since there were issues with changing hardware and software. Their IT department may be able to put something together for me.
Using USB->RS232 connections would be nice given the abundant number of USB ports available on modern PCs.
Without a driver I see parsing the serial text as a challenge in LabVIEW. I know how to approach this with a traditional programming language but are there any examples around here of how this is done with LV (most recent version is fine)?

Is it possible to import simulink blocks into labview

Hi,
I was wondering if it is possible to import the MATLAB/simulink blocks into labview.
thanks,
Baran.

Hi Baran,
There is no way to directly import any of the programing blocks from The MathWorks, Inc. Simulink® software into LabVIEW.
However if you wanted to use your own code that you programed using The MathWorks, Inc. Simulink® environment in LabVIEW, we do have the NI Simulation Interface Toolkit which you can use.

Can we demodulate the signal recieved at DAQ card without using any hardware interface(by only using labview)?

Hi all,
Can we demodulate the signal recieved at DAQ card without using any hardware interface(by only using labview)? if yes then how? please give brief idea.

There is probably a way to do it, but it it may be easier to use an X-series board for the job. They support a new counter capability for count reset on a digital edge without needing to be configured in encoder position mode. I am not sure exactly how that feature's been implemented however, so maybe it won't make things easier after all.
The plan based on the hoped-for behavior:
1. Configure an X-series counter for pulse generation based on "ticks" of your clock channel.
2. Set both initial delay and low time to the critical # of ticks.
3. Configure for count reset on a digital edge (if possible in pulse generation mode)
4. Configure the count reset value to be the critical # (or possibly 1 less, if possible in pulse generation mode)
5. If you want the output to remain high indefinitely, configure the counter task to use its own output as a
pause trigger, and pause while high.
The way pulse generation works is to preload a # of "low time" ticks into the count register. Then every source edge will decrement the count. When the count reaches terminal count (0), the counter's output is toggled (or can be configured to pulse). The register is then loaded with the # of "high time" ticks and the process continues.
You would be perpetually interrupting the count-down process as long as you got your triggers in time. The count would keep getting reset to the # of low counts, keep decrementing toward 0 without reaching it, and so on. If ever you did reach 0, the output state would toggle high, then the high state would prevent subsequent clock signals from decrementing the count.
You can conceivably do a similar thing with a 6601, but I'm pretty sure you'd need 2 counters working together to get it working.

Integration of C++ program into Labview

I have written a C++ program that generates low level code to control a machine. I would like to integrate this program into Labview. I would like to know what would be the best approach to do:
- use CIN (code interface node). Can I take a few parameters as inputs and pass a string of characters to labview? Originally the C++ program generates a text file with the comands to control the device, I guess this can be substituted by a string control/indicator that will control the GPIB device.
- use ActiveX
- DLLs??
Thanks in advance for your help.

Madrid,
I would recommend that you stir away from CINs. If you can compile your C++ code into a DLL, then you can easily call it from LabVIEW. CINs have the disadvantage that if you change your code in anyway, you have to update the CIN node in the diagram of the VI. However if you recompile your DLL, you don't have to inform LabVIEW that you have a newer version of your DLL. If the newer DLL is in the same path that LabVIEW is searching, then it'll link to it automatically.
ActiveX is also a good choice. It might take more development time than creating a DLL though.
My two cents,

Interface between paravision and labview

Hi,
Does any one here who can help or give some idea how to make an interface between paravision and labview software???I need to acquire captured MRI image from paravision and store it to Labview.
I would appreciate for any kind of assistance.
Kind Regards,
Jasim

Hi Jasim,
Could I get a little more information about how you are importing the MRI image into LabVIEW?
1) How are you getting the MRI image into LabVIEW?
2) What image format will the image be in?
3) What will you be doing to the image once it is in LabVIEW?

Help with reading information coming from a software into LabVIEW through Serial port

Hi,
I am new to LabVIEW and also an amateur in using RS232 for communication. I have this software that has these icons like speed increase/decrease, elevation up/down, start/stop. Now, when I click these buttons on the software, they perform the appropriate functions. For example, if I press start button, the signal must go through a serial COM port into LabVIEW to start the machine. How do I do that? How do I find what format the code word is when I press a button on the software? And how to decode the information to read whether the button pushed is start etc...? Any help would be appreciated.
V
I may not be perfect, but I'm all I got!

That information would be in the programming manual for the device you're controlling. Unless you have a device that has no documentation or you cannot get the documentation that's the first place you should look. If you cannot get the documentation at all then you've got some reverse-engineering to do. To do this you will either need a serial port sniffer (a hardware device), or you can try to use a software-based port capturing program. On Windows PortMon is the most prevalent. This will show you how the port was configured (baud rate, stop bits, etc). Warning: the information is technical.
As far as how to get it running in LabVIEW, you should take a look at the serial port communication examples that ship with LabVIEW. The most problems occur in figuring out how to (a) terminate a write command, and (b) determining when to stop reading. For (a) this is typically done by appending a carriage return or linefeed to the command. This is device dependent. For (b) this is usually done by the byte stream ending with a character like a linefeed. Again, this is device-dependent.
You may also want to peruse this KB article: Serial Instrument Control Tutorial. There are also lots of tutorial on the internet for basic tutorials on serial port communication.

How can I get an unsigned char string with nulls from a dll into LabVIEW 6i?

The following ethernet packet data is contained in an unsigned char * string returned from my dll (it's formatted on printing):
Received A 230 Packet On Adapter 0x008F0070
Ethernet Dest: 01.E0.BB.00.00.15 Src: 00.E0.BB.00.DD.CC Type: 0x8868
000000: 01 E0 BB 00 00 15 00 E0 : BB 00 DD CC 88 68 48 41 .............hHA
000010: 00 E0 BB 00 DD CC 80 B3 : 00 00 FF FF 00 02 00 01 ................
000020: 01 00 F0 18 FF 7F 7F FF : FF 7F 7F FF FF 7F 7F FF ................etc., etc.
However, when I read this string into LabVIEW 6i, I only get the following:
01E0 BB
Which is the data before the first NULL or 00 information. I found a "Remove Unprintable Chars.vi" but it
just sees more data before the above string, nothing after, as seen here: 5C30 31E0 BB.
Anybody have any suggestions for how to get the rest of the string? Is there something I can do to further reformat my dll? The dll I'm using is already a wrapper around another dll so I have some flexibility, but the bottom line is, the data I want is in the format of an unsigned char *.

Excellent advice, this mostly works so I have some further questions:
I am just reading network traffic off my ethernet card right now, but here is what I get using my C program to test:

And here is what I get using LabVIEW to call the dll:
0015 00E0 BB00 DDCC 8868 4841 00E0 BB00 DDCC 80B3 0000 FFFF 0002 0001 0100 9600 7F7F 7F7E 7F7F 7F7F 7F7F 7F7F 7F7F 7F00 B405 4300 3300 0000 0000 0000 01E0 BB00 0015 00E0 BB00 DDCC 8868 4841 00E0 BB00 DDCC 80B3 0000 FFFF 0002 0001 0100 9600 7F7F 7F7E 7F7F 7F7F 7F7F 7F7F 7F7F 7F00 F405 1B04 0C04 0000 0000 0000 8000 0000 0000 0000 0800 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000
The first thing I notice is that the first 4 bytes are chopped off, and after about 50 bytes, the data is corrupted until the sequence starts to repeat, but this time it starts with the missing 4 bytes and still corrupts after about 55 bytes.
I am expecting the data in LabVIEW to look very similar to the C data because the network packets I am grabbing are pretty consistant, only a couple bytes will vary between them, not the number I am seeing in LabVIEW.
Another side effect I'm seeing is that I can only run my labVIEW code once, if I try running it again it crashes with failures such as:
memory could not be "read"
For reference, I am opening and closing the network adapter inside the read function of my dll, but the pointer seems like it should be intact...

Way to acquire more than one sample at a time into Labview from cFP?

In reading data from my cFP into Labview I see that I can use the FP Read.vi but it only grabs one sample per call (loop iteration). In other devices, I could just use the AI Acquire Waveform.vi to grab multiple samples per call. Can I use this for cFP? Is there another way to grab more than one sample per call from my cFP? I'm just running it from a host computer, not using RT.
My specific problem is that I have two things I want to do with the same signal, one slow (PID control loop) and one fast (data logging). If I put the FP Read.vi in the same loop as the PID control, I can only get one sample in the time it takes the PID loop to run which is too slow. I'm trying to think of ways around this problem.
Thanks,
Hosehead

Hello Hosehead,
With FieldPoint there is no way to acquire more than one same at a time like
you can with NI-DAQ. With the FieldPoint read and write VIs
you can only read or write a single point at a time.
Please see the Sampling
Speed of FieldPoint Modules document for more information on cFP
acquisition rates. This document explains how channels are updated, how
often the data is updated, and what happens if you miss samples. Please
note that you will be able to acquire more samples if you are running your
application on the RT controller and not on your host computer.
If this does not answer your question, can you please post more data about the rate
you want your PID loop and your data logging loop to run at.

How to import Verilog codes into LabVIEW FPGA?

I tried to import Verilog code by instantiation followed by the instruction in http://digital.ni.com/public.nsf/allkb/7269557B205B1E1A86257640000910D3,
but still I can see some errors while compiling the VI file.
Simple test Verilog file is as follows:
==============================
module andtwobits (xx, yy, zz);
input xx, yy;
output reg zz;
always @(xx,yy) begin
zz <= xx & yy;
end
endmodule
==============================
and after following up the above link, we created the instantiation file as
==============================================
library ieee;
use ieee.std_logic_1164.all;
entity mainVHDL is
port(
xxin: in std_logic;
yyin: in std_logic;
zzout: out std_logic
end mainVHDL;
architecture mainVHDL1 of mainVHDL is
COMPONENT andtwobits PORT (
zz : out std_logic;
xx : in std_logic;
yy : in std_logic);
END COMPONENT;
begin
alu : andtwobits port map(
zz => zzout,
xx => xxin,
yy => yyin);
end mainVHDL1;
==============================================
Sometimes, we observe the following error when we put the indicator on the output port,
ERROR:ConstraintSystem:58 - Constraint <INST "*ChinchLvFpgaIrq*bIpIrq_ms*" TNM =
TNM_ChinchIrq_IpIrq_ms;> [Puma20Top.ucf(890)]: INST
"*ChinchLvFpgaIrq*bIpIrq_ms*" does not match any design objects.

TNM_ChinchIrq_IpIrq;> [Puma20Top.ucf(891)]: INST "*ChinchLvFpgaIrq*bIpIrq*"
does not match any design objects.
and interestingly, if we remove the indicator from the output port, it sucessfully compiles on the LabVIEW FPGA.
Could you take a look at and please help me to import Verilog to LabVIEW FPGA?
I've followed the basic steps of instantiation on the above link, but still it won't work.
Please find the attachment for the all files.
- andtwobits.v : original Verilog file
- andtwobits.ngc: NGC file
- andtwobits.vhd: VHD file after post-translate simulation model
- mainVHDL.vhd: instantiation main file
Since there is no example file for Verilog (there is VHDL file, but not for Verilog), it is a bit hard to do the simple execution on LabVIEW FPGA even for the examples.
Thank you very much for your support, and I'm looking forward to seeing your any help/reply as soon as possible.

Hi,
I am facing problem in creating successfully importing VHDL wrapper file for a Verilog module,into LabVIEW FPGA using CLIP Node method. Please note that:
I am working on platform SbRIO-9606.
Labiew version used is 2011 with Xilinx 12.4 compiler tools
NI RIO 4.0 is installed
Xilinx ISE version installed in PC is also 12.4 webpack ( Though I used before Xilinx 10.1 in PC for generating .ngc file for verilog code FOR SbRIO 9642 platform, but problem remains same for both versions)
Query1. Which versions of Xilinx ISE (to be installed in PC for generating .ngc file) are compatible with Labview 2011.1(with Xilinx 12.4 Compiler tools)? Can any version be used up to 12.4?
Initially I took a basic and gate verilog example to import into LabVIEW FPGA i.e. simple_and.v and its corresponding VHDL file is SimpleAnd_Wrapper.vhd
///////////////// Verilog code of “simple_and.v”//////////////////////
module simple_and(in1, in2, out1);
   input in1,in2;
   output reg out1;
   always@( in1 or in2)
   begin
      out1 <= in1 & in2;
   end
endmodule
/////////////////VHDL Wrapper file code of “SimpleAnd_Wrapper.vhd” //////////////////////
LIBRARY ieee;
USE ieee.std_logic_1164.ALL;
ENTITY SimpleAnd_Wrapper IS
    port (
        in1    : in std_logic;
        in2    : in std_logic;
        out1   : out std_logic
END SimpleAnd_Wrapper;
ARCHITECTURE RTL of SimpleAnd_Wrapper IS
component simple_and
   port(
         in1    : in std_logic;
         in2    : in std_logic;
         out1   : out std_logic
end component;
BEGIN
simple_and_instant: simple_and
   port map(
            in1 => in1,
            in2 => in2,
            out1 => out1
END RTL;
Documents/tutorials followed for generating VHDL Wrapper file for Verilog core are:
NI tutorial “How do I Integrate Verilog HDL with LabView FPGA module”. Link is http://digital.ni.com/public.nsf/allkb/7269557B205B1E1A86257640000910D3
In this case, I did not get any vhdl file after “post-translate simulation model step” in netlist project using simple_and.ngc file previously generated through XST. Instead I got was simple_and_translate.v.
Query2. Do I hv to name tht “v” file into “simple_and.vhd”?? Anyways it did not work both ways i.e. naming it as “simple_and with a “v” or “vhd” extension. In end I copied that “simple_and.v” post translate model file, “simple_and.ngc”, and VHDL Wrapper file “SimpleAnd_Wrapper.vhd” in the respective labview project directory.
Query3. The post-translate model file can also be generated by implementing verilog simple_and.v file, so why have to generate it by making a separate netlist project using “simple_and.ngc” file? Is there any difference between these two files simple_and_translate.v generated through separate approaches as I mentioned?
2. NI tutorial “Using Verilog Modules in a Component-Level IP Design”. Link is https://decibel.ni.com/content/docs/DOC-8218.
In this case, I generated only “simple_and.ngc” file by synthesizing “simple_and.v “file using Xilinx ISE 12.4 tool. Copied that “simple_and.ngc” and “SimpleAnd_Wrapper.vhd” file in the same directory.
Query4. What is the difference between this method and the above one?
2. I followed tutorial “Importing External IP into LABVIEW FPGA” for rest steps of creating a CLIP, declaring it and passing data between CLIP and FPGA VI. Link is http://www.ni.com/white-paper/7444/en. This VI executes perfectly on FPGA for the example”simple_and.vhd” file being provided in this tutorial.

Seeing these errors I have reached the following conclusions.
There is some problem in making that VHDL Wrapper file, LabVIEW does not recognize the Verilog component instantiated in it and treat it as unresolved black box.
Query6. Is there any step I maybe missing while making this VHDL wrapper file; in my opinion I have tried every possibility in docs/help available in NI forums?
2. Query7. Maybe it is a pure Xilinx issue i.e. some sort of library conflict as verilog module is not binding to top VHDL module as can be seen from warning HDLCompiler89. If this is the case then how to resolve that library conflict? Some hint regarding this expected issue has been given in point 7 of tutorial “How do I Integrate Verilog HDL with LabView FPGA module”. http://digital.ni.com/public.nsf/allkb/7269557B205B1E1A86257640000910D3. But nothing has been said much about resolving that issue.
3. Because of this unidentified black box, the whole design could not be mapped and hence could not be compiled.
P.S.

I wish to know whether a program in VB can be downloaded into labview to make it into a VI

I am interested in controlling a stepper motor using labview. I have the program developed in VB and the code is working perfectly. I wish to know whether it is possible to convert the VB file into a VI file with all the control palettes and loops. If yes, please give me the method of doing it.

I'm not aware of any method for directly "translating" Visual Basic code into LabVIEW. However you can make use of the ActiveX and DLL access capabilities of LabVIEW to control a VB application.
Also, I would suggest that you post your question in the LabVIEW section of Developer Exchange and not in the Motion section, in that way your question will be seen by LabVIEW users and not only Motion Control users. There will be lots and lots of more users in LabVIEW than in Motion Control that may give suggestions.
The Development Library section in the Developer Zone will provide you with code and application notes for controlling external applications or code with LabVIEW.
Good luck!

Loading a Previously Saved Task into LabView

I have created a digital generation task in LabView and saved it using DAQmx Save Task.vi. I am able to open and run my task in Measurement and Automation Explorer. Now I am wondering if it is possible to load this task back into LabView and run it in a new program. Can I do this with the task saved from DAQmx Save Task.vi or would I need to go about it differently? Where would I start loading the task in terms of vi's?
Thank you for your help.

I am actually not asking the same question as before. Previously, I was having problems using a LabView-created task in MAX. Now I am attempting to create a task in LabView and bring it back into LabView on a separate VI. I have found the answer, though.
