Procedure for: LabVIEW Purpose: This procedure is to continue to introduce the LabVIEW programming environment and the G programming language. The lab demonstrates several key concepts including: The FOR loop,

The WHILE loop, Data Types: Integers: 8-bit signed 8-bit unsigned 16-bit signed and 16-bit unsigned Fixed Point Numbers Floating Point Numbers Single Numbers Double Numbers Extended Numbers Complex Numbers Strings (Characters) Data Structures: Stings Arrays Clusters G-Functions Laboratory Procedure Build Array Convert Boolean Array to a Number Convert a number to a Character String Concatenate Strings Greater Than Or Equal To, Comparison Arithmetic Functions, Add, Subtract, multiply, divide Debugging Features: Data Flow Error List and broken arrow Breakpoints Probes I. In this section, you should learn (review): 1. How to create a VI (LabVIEW Program) and what are its major parts Build the First VI: Numbers-FOR-WHILEloop.VI Laboratory Procedure 2. How to change and use the various mouse functions/Tools. 3. How to access the various Controls and indicators for the User Interface. 4. How to access the various coding Functions for writing the program. 5. How to arrange and connect the functions together to accomplish a task. 6. How to use the WHILE loop to repeat operations. 7. How the Event Structure is used. 8. How to align and space items on both the User Interface and the Code window to make the program more usable and understandable. 9. How Boolean buttons are used 10. How to build an Array of Booleans and convert it into a decimal number. 11. How Loops that do not depend on each other execute in parallel. Lets begin. A. Start LabVIEW; Find LabVIEW in the start menu or the LabVIEW Icon on the desk top and activate it. B. When the splash screen appears Click "Close" to remove the "Welcome to LabVIEW" screen. C. At the LabVIEW screen go to FILE>>NEW VI D. Two Windows will appear that are the first two of the three parts of a VI: X Untitled 1 Front Panel File Edit View Project Operate Tools Window Help II 20pt Application Font ➜ 23 90x • +0 69 Front Panel: User Interface of the VI Untitled 1 Block Diagram File Edit View Project Operate Tools Window Help 20 20pt Application Font P 40 m 3 D Search Y E Search ?

The finger to operate controls b. The Arrow to select items c. The Text "A" for entering text d. The Spool of Wire for connecting items and e. The Paint Brush for adding colors for quick recognition of items 3. Click the Help button on the Tool Bar and select "Show Context Help" a. The context help will provide a brief description of items when the mouse hovers over the item Laboratory Procedure b. There is a link on the context help to a more detailed explanation of the item if more detail is required. 4. Right click on an empty area of the Front Panel and the "Controls Palette" will appear.
