Obtaining Data from a Raspberry Pi

[mlw1624]

Hello all!  I have a Raspberry Pi 4 Model B for my Senior project. I have it set up already with LINX. So my question is. What should I use to be able to obtain "Real World" data such as Voltage and Current. Then use those values in my LabView program. I've read on a couple of posts that the VISA blocks are what I should be using with the help of LINX. I'm just a little confused on what blocks I should be using to obtain my data since there are so many VISA blocks. All help is appreciated. Thank you!
