como graficar una señal acondicionada en arduino?

buenas para todos. estoy integrando arduino con labview. quiero graficar mi señal de 0-5v que acondicione, tambien poder graficar su espectro de frecuencias. gracias

neoflash,

Sorry I don't speak Spannish.  The google translation of your post is:

good for everyone. arduino am integrating with LabVIEW. I plot my 0-5V signal that conditions, also to plotits frequency spectrum. thanks

So I assume you are trying to plot the frequency domain of an alalog signal you are acquiring with LIFA.  You can use the FFT vi to convert your results to the frequency domain and display them on a graph or chart.  Let us know if this is not what you are trying to do.

AMIGO NEOFLASH, es muy fácil integrar arduino a labview y obviamente graficar señales analógicas, solo tienes que instalar las tolkits de arduino

en labview tal y como lo enseñan en el siguiente tutorial:

https://lumen.ni.com/nicif/us/evaltlktlvardio/content.xhtml

o bíen, en el siguiente:

http://vishots.com/getting-started-with-the-labview-interface-for-arduino/

Simplemente es instalar los drivers en labview y el toolkit para que acepte la comunicación con arduino, y a la placa arduino cargarle un firmware que se denomina LIFA, Que despues de instalar todo queda guardado en:C: \ Archivos de programa \ National Instruments \ LabVIEW 2010 \ vi.lib \ LabVIEW interfaz para Arduino \ Firmware \ LVIFA_Base \ LVIFA_Base.pde

YO HICE LA PROGRAMACIÓN PARA OBTENER LA SEÑAL ANALÓGICA DE FORMA GRÁFICA EN LABVIEW Y ME QUEDÓ ASÍ:b.png

y ya eso es todo, para ver el resultado mirate este video:

y para aprender a usar labview:

espero que te sea útil, cualquier duda me la haces saber.

Hi Sammy K
Thanks in advance for your help
I have a question I am using the arduino interface, I can use the I / 0 digital and analog inputs, but requires the use of digital filters in LabVIEW, you could help me with an example?

Hey vicoba,

What kind of digital filters are you going to be using in LabVIEW? You will probably need to take multiple samples from the Arduino and turn that into waveform data to use with the Filter VI's.  This conversion to waveform data will not be very accurate with the current setup of the LIFA since the maximum sample rate is dependent on the rate of serial communication between the Arduino and your computer.  There will be some improvements coming to this in the next release of the toolkit but for right now you will be pretty limited in the speed you can sample at.

hi thanks for your response sammy and Kevin_F, I solved the problem with analog filters through anyway, now I have made ​​the executable program and download the labview runtime for 2010, this to another PC where LabVIEW is not installed, the executable runs well but not recognizes the port where the arduino one, which can be?, the port can select the user because it can be different for each computer, I go a couple of pictures for better analysis, which may be what I am doing wrong?
