I am fairly new to LabVIEW but I wanted to know if it was possible to run two different DAQmx tasks in the same loop? I want to read and filter analog voltage input and view thermocouple readings. Below is a picture of how I currently have them running but I want to know if I can integrate them into the same loop.

LabVIEW: USRP Tx IQ samples from .csv file

Hello all,

 

I was hoping to get some advice on how to transmit an array of comma separated IQ samples from a USRP.  My current set up consists of

 

LabVIEW 2016

NI USRP driver

NI USRP 2932

 

I have successfully transmitted a few waveforms using examples I have found on the forum so I know the correct software is in place.  I have read that it is possible to transmit an array of IQ samples from a file but I haven't seen an example on how to do so.  I am still a little new to LabVIEW so any help is appreciated.  If any other info would be helpful I will try to provide it.  Thank you!

Using the (N-1) data from N data points

Hello everyone,

I am receiving continuous set of data points (average and stand dev.) from the VI with time. Like as, when it is 1s, i get one data, when two second i get another data and it continues. So continuously i am having the last point data if I want to use it for other purposes. My issue: I want to use the previous point data and use that with the present data. Example: Equation: (Present point - previous point); But i don't have the previous data as i am having the last data continuously. How can i store the previous data continuously and use it with the present one? Like as whenever, my third point comes up, i want to use both the third point and second point.

 

Thanks,

How to use Invoke Nodes on VI

$

I'm trying to use an Invoke Node on VIs so i can call it from another VI, i tried a lot of exemples but none of them works, and its been hours of reading and reading but i havent found a solution, what im trying to achieve is that i want to call a VI from another VI,  is it that hard?!?!


*Invoke Node to call Control_Manual when you select Control Manual from Enum (VI: Panel_Frontal)


Also I want to close the SubVi when I'm done, pushing a button and re-direct to Panel_Frontal, after that i will call a second VI the same way like the first one, but i believe that if i get help, calling the second VI will be the same way.


Please I've been reading from10AM to 7:11PM and no results T.T

SPI on myRIO with synchronous 8 channel ADC

$

Hello I am working on an acoustic direction finding project that uses time difference of arrival of 8 analog microphones to determine the direction of an acoustic event. I have an ads1278 which provides delta sigma ADC. I have not done any SPI parsing on LabVIEW so I am trying to get some help on what my limitations are and what the community would recommend for the best implementation for a beginner like myself. I see the default SPI VI can run up to 16 bits, so I am curious would I only be able to run the 24 bit ADC device through FPGA? If I acquired the ADS1178 (same link) 16 bit version that provides a slower sampling rate, could I get the MISO through the default SPI VI and avoid using FPGA? Any help will be greatly appreciated! 

 

Thanks.
