Have you searched the Web or read the documentation you get with a myRIO? Are you a student? Have you talked to your instructor or classmates? Are you looking for a Personal LabVIEW Guru (if so, please learn how to spell LabVIEW ...)
BS
Bob's explanation may seem a bit harsh, but there is reason for it. Many single aspects of LabVIEW could be used as a career for the rest of your life. Asking for "basic VI of LabVIEW" is like asking the basic wrench for fixing a car.
Here is some free training on the myRIO essentals guide. It has examples, documentation and youtube videos.

It is by no means a complete guide to LabVIEW. I'm at my 14th year of doing this daily, and am still learning.
