If you already have a large block diagram this could lead to more difficulty navigating within your diagram. LabVIEW Navigation Window : If you want to zoom out to get an overview of the code, you can use the Navigation Window to easily select or move to the code that you want to edit (if the VI is too large to fit into a single window). LabVIEW ties the creation of user interfaces (called front panels) into the development cycle. LabVIEW programs/subroutines are called virtual instruments (VIs). Each VI has three components: a block diagram, a front panel, and a connector panel. The last is used to represent the VI in the block diagrams of other, calling VIs. The Navigation window displays an overview of the active front panel in edit mode or the active block diagram. We can use the Navigation ... r/LabVIEW.

LabVIEW is a graphical programming environment. Unlike C/C++ where programs are written in text, in LabVIEW creates Virtual Instruments (VIs) by graphically composing them from different elements and structures that are placed like the blocks of a block diagram and interconnected with wires to indicate the intended signal flow paths.

From the menu bar on the front panel, select Window >> View Diagram. If that option's not there, the VI was saved without a diagram so you won't be able to view it. Saving a VI without a diagram is an option which can be used when you distribute your VIs so someone else can use them but not see or alter your code.

Step 2: Front Panel. When you open your blank VI, it'll open two windows - a front panel and block diagram. The front panel is a visual representation and helpful tool for user inputs and measurements from the code. Each module on the front panel has a corresponding block or section of code that is created and can be found in the block diagram.

The centre frequency of the plucked filter is dependent on tension in fabric. If you start with white noise you must convert that to random trigger events. Maybe use a comparator that detects when the random noise amplitude is greater than a set value. The positive edge of that triggers the drum filter. You do not identify your...
