Advice for data transmission from LabVIEW to C (or Python, etc)
We are designing a LabVIEW application from where I would like to send data to external applications written in C or other text language. So some text coder colleagues could test raw measurement data in parallel time by time. The data to be sent usually consist of maximum 1 million integer values, type U16. The natural choice would be TCP or udp protocol to be used. The C code would be run occasionally on the same computer (localhost) or on another one being in the same LAN.
I have read several posts dealing with similar questions but I could not come to a final conclusion yet, what would be the best approach in my case.
I wonder if udp protocol could fulfill my needs as I know that pocket losses are very unlikely in a simple LAN network. But an udp datagram is limited in size (50000 bytes or so), so I would need several packages to send. So maybe I would go for the TCP protocol. Another question comes to my mind is which side should be the server and which side the client, or does it really matter? Finally I wonder what would be the best way to format the data to be sent. I have to dig into some C code examples, to see how to deal (buffer size settings, data parsing from string, etc.) with incoming TCP data, so I do the LabVIEW side code in the required way.
Maybe some of you had to build such system before, so could give me some hints and good advise...
Thanks!

Filter sine with square envelope
Hi!
I have generated a sine signal with square envelope (signal for echolocation). My task is to add White Gaussian Noise, which I already did and then to filter the noise.
How can I filter the noise with this kind of signal? I tried Bandpass IIR, but it does not completely filter the signal.
Here are signal parameters:
Sine frequency: 5kHz
Square signal period: 0,2 s.
Below signal in time domain and the spectrum without the noise:

Max and Minimum values incorrect for serial communication - VISA - MLX90621
Hello All,
I have a temperature sensor of resolution of (4*16) and am reading the values through a serial port using VISA - (The values keep refreshing very quickly). The output array values are correct but when i try to see the max and min values from the same array they are incorrect.
Could some one please help me, i have just started learning labvew.
And please excuse me if this is a dum question.

Generating output signals
Hi everyone,
Here's a very basic question. When hitting the run-button in labview, does it automatically transmit the signal from the hardware - or do I have to do something in order to get out of the simulation mode?
I'm using a BNC-2120 along with a NI PXIe-1073 and NI PXIe-6368. In labview, a square wave from the simulate-signal-block is sent to the DAQ Assistant. I've connected an oscilliscope to the analog output but all I get is noise.
Thank you in advance from a labview novice.

LabView + Ardino IR remote
Hello! This is my first post here hope I'm doing this right. Please go easy on me =')
So I just started using LIFA a few days ago and was trying to connect the remote that came with the Arduino starter kit (Elegoo EL-KIT-003) but couldn't quite understand how it works. This is how i connected the IR receiver: connected the ground and 5V pins to their respective places on the uno board and then connected the signal PIN to digital pin 11.
I set up the VI to read the digital input from pin 11, but all it outputs is the change from HIGH to LOW whenever i press any of the button on the remote. I don't understand how to assign different functions to each button if all they do is change High to low? Any help would be appreciated thank you <3

DLL is always copied during creation of lvlibp
Hi everyone,
in our "scriptengine" project which is going to be used in other Projects some VIs use a DLL.
To be easily used in other projects, I create a lvlibp.
Now during build of the lvlibp the DLL is always copied from source to destination directory. Then I have two DLLs and LabVIEW gets confused from which directory to load the DLL.
I have checked "exclude dependent libraries" in build specifications.
It does not make a difference if I include the DLL in the scriptengine project or delete it from the project and see it in dependencies.
Some self-made DLLs I can register in the GAC, but for sapnco.dll e.g. I can not do that.
Do I have to make a VI which deletes the copied DLL after the build or what can I do?
Thx in advance

Simple example with C code for labview
Good morning,
I need help. I'm looking for a simple program which uses C code in Labview , and I'm not finding nothing.
I want to know how I can generate the code in Eclipse, then, how I built the .dll library, and then, how I use this .dll library in Labview (I think that, it will be with call library block fuction, really?)
Thanks so much. I'm new in this item.

Erroneous input values from accelerometer
Hi! I hope this is the correct topic for my question. I struggle at making my acquisition system acquiring correct measurement values. I use a NI USB-4432 device with LabView 2014 SP1 on windows 7. My setup involves an impact hammer test. In particular, I use a PCB ICP 086E80 impact hammer and a PCB ICP 352A24 accelerometer (-50G to + 50G, with 100 mV/G as sensitivity, with excitation current of 2,1 mA). The hammer enters the ai0 channel, while the accelerometer is put on the ai1 channel. Finally, the hammer triggers the acquisition of both the hammer impact and acceleration within the device. The trigger is an analog edge with rise slope. The DAQ assistant virtual channels settings are attached as images. Basically the hammer impact range is from -5 to 15 N, while the accelerometer is used at its full range (-50G to 50G). My problem is the following: when I perform the impact, the accelerometer registers an acceleration which initially ranges from -120 to 120 G, then correctly sets on values below +-50 G. I would expect my accelerometer to saturate, nevertheless the acquired waveform seems not having troubles with such out of range values. I tried to convert the virtual channel from acceleration to voltage and measure the input. In this configuration, the sensor seems not to saturate at +- 5 Volts, which should correspond to +- 50 G for the acceleration. I have attached some screenshots to better explain the problem.
I hope someone could help me, as I tried everything but still cannot get my head around it.
Thank you in advance to everyone would help me!

Problems with school project
Hello,
I have problem with my school project. I have never done in labview before but i get new school project what i have to do.
I need someone to help me. My teacher give entred us new project in Labview. Unfortunetlly we havent been doing so much work in Labview before.
My project is:
To shown grpah with function x2 with case structure. The program allows multiple display with X parameter change. Also its able to change number of points of the function and number of curves displayed.
sorry for my english
thanks for any help i really dont know what to do

Error Wiring Style
I and I'm sure many others have the habit of running the error wire as seen below. Note the style how the error always heads directly downwards from VI's and is aligned horizontally to some common level.
Image may be NSFW.
Clik here to view.
The default automatic wiring (e.g. when you use Remove and Rewire, which I for one use a lot), however, doesn't follow this style. I wouldn't go as far as to say it's a major inconvenience but it does add to the manual cleaning up.
Is there any way to configure the LabVIEW default/automatic wiring style to use this pattern?

FPGA and Acquisition module Clock. Synchronization issue
Hello All,
I have a C-Rio 9082 with NI 9225 acquisition module for Voltage, NI 9227 acquisition module for Current and NI 9467 for GPS Synchronization. How can I get the Time Stamps of each sample acquired from NI 9225 and not only for PPS? Is there a way to use the same clock for FPGA and the acquisition modules?
In image "1" I wait for gps synchronization and save with local variables the value of a Timer and the value of Numeber of Samples between 2 PPS. In image "2" I start the acquisition but this use onboard module clock and not the fpga clock so I cannot go up to the time when samples were acquired.
(I can use the same clock for acquisition modules but not the same of CRio)
