The most important thing to learn LabVIEW is your programming idea, because LabVIEW is a graphical language, without too many coding language rules, it is easy to get started, and the corresponding front panel is very operable. Therefore, as long as your programming logic is good, you will get started quickly and accept large programs easily.
You'd better lay a good foundation when you just start studying. The more basic things you have, the more helpful you will find when you use them, because they are used frequently. If you haven't received LabVIEW training, you can buy some basic books to read.
Then, the basics are finished. Because LabVIEW is widely used in industry, you'd better have a project for you. In the process of doing this, in order to realize various functions, you should not only make full use of the cases brought by LabVIEW, but also go to the forum for electronic enthusiasts to discuss. Many great gods will provide more in-depth implementation methods in the forum, and you can make good progress in this process. Every time you solve the problem, your understanding and use of LabVIEW will get better and better.
