This week I attended my local LabVIEW User Group (CSLUG). I have been a member for a few years and can't emphasise enough how much you can get out of a two (sometimes three/four) hour discussion once a quarter.
Topics that are discussed can be anything from new and advanced ideas, different ways of documenting code, error handling and anything else that you have an interest in or need help understanding. I am lucky enough to be part of a LabVIEW User Group that has three LabVIEW Champions and a very long list of LabVIEW Architects and Developers who are more than happy to share their knowledge and experience with those willing to learn.
Here are a few reasons to join a LabVIEW User Group in your area, and if there isn't one, maybe get hold of NI and start one.
What I got out of CSLUG this week:
The biggest idea I got from this weeks LabVIEW User Group was from a chat once most people had gone home. Late on the night before CSLUG I was working on a calibration process and was wondering how to get a value from the previous three states in a while loop. It was late, the code was working but could have been better so I left it for the night.
Then after CSLUG, someone mentioned something about multiple shift registers and something just clicked. I went home and immediately wrote a simple vi to test what I thought he meant and it was exactly what I was looking for.
The idea is that adding a shift register to a while loop gives you access to the value of the previous state. This I always knew and use often. What I didn't know is that you can add multiple input terminals to a single output terminal. This means that the top input terminal is the data from the previous state, the terminal below is the data from the state before the previous state and so forth.
Here is a video of it in action.
My hope for the new year is to try and get to some other LabVIEW User Groups in the area, to meet new people, learn something new and hopefully teach someone else something new.
Have a great Christmas, New Year and happy coding.
