• #8: Oggi il Software è un “qualcosa” che deve aiutare !!!!Ad oggi il Software è uno strumento che deve mettere chiunque degli addetti ai lavori, in condizione di raggiungere un risultato valido e funzionale nel minor tempo possibile e con la massima efficienza !E’ uno strumento che chiunque deve essere in grado di usare in modo semplice e non specialistico ! ... Non si deve essere dei softwareristi specializzati per poter usare uno specifico software.E’ uno strumento che deve poter definire la personalizzazione delle funzionalità del proprio dispositivo in base alle specifiche esigenze.E’ uno strumento che deve aprire all’intergrazione e non creare dei limiti
• #9: Il Software è paragonabile agli optionals di una macchina (vedi Fiat 500), sono quegli strumenti semplici da usare, che fanno la differenza, che consentono di affrontare un viaggio più o meno lungo con piacere e tutti, chi meglio e chi invece meno, ma TUTTI, sono in grado di usarli.
• #15: The LabVIEW front panel includes over 300 controls and indicators designed specifically for measurement applications. Each object is configurable, enabling you to create professional graphical interfaces. A control is a front panel object for user input. Simple examples of controls include buttons, slides, dials, and text boxes. An indicator is a front panel object that displays data to the user. Examples of indicators are graphs, thermometers, and gauges. When you place a control or indicator on the front panel, a corresponding terminal is placed on the block diagram.
• #16: Build a front panel by dragging and dropping controls and indicators from the Controls palette. Similar objects are divided into subpalettes for easier navigation. Right click on any open space on the front panel to bring up the Controls palette, and navigate through the palettes by hovering over the category icon of object you want to add. Left-click on an object in the palette and it will be placed on your cursor. Move the object to the desired location and left-click to drop it onto the front panel. Once placed you can move or resize the object, or right-click on the object to adjust other properties.To access front panel objects by name, press <ctrl + Space> while the front panel is active and the Quick Drop dialog will appear. Search for objects using any part of its name and a list of possible choices will appear below. Double click on the name of the object you want it will be placed on your cursor for use on your front panel.
• #18: LabVIEW is a dataflow programming language. This means that data flows from one function to one or more other functions and propagates through the application. Unlike text-based development software, LabVIEW, because of its dataflow capability, is not sequential and can execute multiple operations in parallel using its intuitive diagram representation. For example, as you can see in this slide, the two Simulate Signal Express VIs execute in parallel. LabVIEW is a multithreaded programming environment, meaning that multiple operations can occur simultaneously without interfering with each other. Additionally, our redesigned NI-DAQmx data acquisition driver software also allows you to perform multithreaded measurements. LabVIEW is a compiled graphical dataflow programming that maps functional blocks to concepts. At the core of the LabVIEW platform is a graphical programming language called “G”. Compiled for comparable execution to C, LabVIEW G is based on dataflow technology, particularly suited to rapidly designing systems with parallel execution of tasks. The graphical nature of the language is typically a much more intuitive development paradigm for engineers and scientists than a text-based solution – it mimics the flowcharts with which these users are very familiar.The LabVIEW language abstracts a great deal of artificial complexity created by other programming tools, enabling higher productivity and faster development for test, measurement, and control applications.
• #19: Data is passed between functions on the Block Diagram by wires. Wires represent different data types, and both color and wire thickness are used to help differentiate the type of data a wire carries. A single wire can serve as an input for multiple functions across and application. Wires will appear broken if you connect a wire of one type to a function input of another type. The LabVIEW compiler processes each action you take while you code and alerts you of any errors with a broken run arrow. You can press the broken run arrow at any time to display a list of errors. Double click on any error and its location in your application will be highlighted.
• #20: Just like finding front panel objects, right-click on any empty space on the block diagram to display the Functions palette, and navigate through the palettes by hovering over the category icon of object you want to add. Each palette icon represents a subpalette, which contains VIs and functions that you place on the block diagram and wire together to create your code. Left-click on a function or VI in the palette and it will be placed on your cursor. Move the object to the desired location and left-click to drop it onto the block diagram to incorporate into your application. To access functions by name, press <ctrl + Space> while the block diagram is active and the Quick Drop dialog will appear. Search for functions using any part of its name and a list of possible choices will appear below. Double click on the name of the function you want it will be placed on your cursor for use in your block diagram.These function libraries provide everything you need in terms of the constructs and functions found in any programming language as well as functions that are unique to LabVIEW. These palettes, specifically designed for measurement and automation applications, truly differentiate LabVIEW from more traditional text-based programming languages, making it easy to find and use thousands of pre-made functions. With your productivity in mind, many templates, design patterns, and frameworks are available for typical applications to give you a head-start on development to ensure that you never have to start from scratch.
• #29: In the past, vendor-defined instruments were necessary for data acquisition systems. Those instruments were limited to the functionality designed into them by the manufacturer, eliminating the ability to customize them for a specific solution and requiring extra time and equipment to incorporate them into larger systems. When LabVIEW launched in 1986, National Instruments introduced a new concept for data acquisition: virtual instrumentation.Virtual instrumentation involves designing your application on standard desktop PCs and then deploying it to whatever hardware platform your application requires, including desktop, automated test, industrial and embedded devices. This method allows developers to use flexible, off-the-shelf hardware to create custom acquisition and control systems. It also speeds up the overall development time of your system since there’s no need for custom equipment or learning multiple programming languages for each hardware platform you use.Virtual Instrumentation is possible because of LabVIEW. LabVIEW is a graphical programming language that allows scientists and engineers to program their own applications with its easy-to-learn environment. LabVIEW works seamlessly with NI hardware and contains over 6000 instrument drivers to connect with your existing hardware.
• #30: LabVIEW uses a single driver, NI DAQmx, to integrate with all NI DAQ platforms. Your code will execute the same on different DAQ systems, leaving channel selection and hardware bandwidth as the only variables. This means that you can distribute the same application you developed on your desktop to various other form-factors and buses depending on your application requirements.
• #61: If you can’t find a local or online group that meets your needs, consider starting your group. They’re easy to set up and the User Group Leader’s Group includes presentations and other content you can download and share, as well as video tutorials and discussion forums for user group leaders.
• #62: The LabVIEW Idea Exchange is an open forum for submitting, collaborating and voting on new feature ideas for LabVIEW. LabVIEW R&D engineers monitor this board and implement as many of the most popular ideas as possible for each LabVIEW version release.In 2009: 749 ideas submitted 14,158 votes on those ideasR&D is very bought in to implementing as many popular user features as possible, as this process helps them prioritize their time and resources. We expect even more of the top user-submitted features to be implemented in future versions of LabVIEW.
• #63: We have created a central location for LabVIEW users to find all third-party LabVIEW add-ons and utilities. We are also working on creating a valid partner program and marketplace to increase the number and overall quality of LabVIEW add-ons.
