8. National Instruments Confidential7 What is LabVIEW? Science Technology Engineering Math Graphical programming language & Data flow LabVIEW relies on graphical symbols rather than textual language to describe programming actions The principle of dataflow, in which functions execute only after receiving the necessary data, governs execution in a straightforward manner

10. National Instruments Confidential9 How does LabVIEW work? LabVIEW programs are called:  Virtual Instruments (VIs)  because their appearance and operation imitate actual instruments. However, they are analogous to main programs, functions and subroutines from popular language like C, Fortran, Pascal, …

11. National Instruments Confidential10 Front Panel Controls = Inputs Indicators = Outputs Block Diagram Accompanying “program” for front panel Components “wired” together LabVIEW Programs Are Called Virtual Instruments (VIs)

12. National Instruments Confidential11 LabVIEW Introduction Two “sets” for development  Front Panel  Block Diagram Wiring connections LabVIEW Conventions Running LabVIEW programs

13. National Instruments Confidential12 LabVIEW Front Panel All user interface goes here! Used to display Controls or Indicators Highly customizable

14. National Instruments Confidential13 LabVIEW Block Diagram Actual program Invisible to user Read left to right, like a book Where the MAGIC happens!

15. National Instruments Confidential14 Terminals When you place a control (or indicator ) on the FRONT PANEL LabVIEW automatically creates a corresponding control (or indicator ) terminal on the BLOCK DIAGRAM

16. National Instruments Confidential15 Control? or Indicator? Controls = Inputs from the user = Source Terminals Indicators = Outputs to the user = Destinations

17. National Instruments Confidential16 Manipulating Controls and Indicators Right click on an indicator to  Change to control  Change format or precision Right click on a control to  Change to indicator  Change mechanical action (whether to latch open or closed, and what to use as default…)

18. National Instruments Confidential17 Wiring Connections Wires transport data through the block diagram Wire color indicates variable type A red “X” means something is wrong!

19. National Instruments Confidential18 Wires A LabVIEW VI is held together by wires connecting nodes and terminals; they deliver data from one source terminal to one or more destination terminals.

22. National Instruments Confidential21 Example 1: Craps From the functions – numeric panel insert a pair of dice From the Controls panel insert a numeric digital indicator (on the front panel) Use the wiring tool to connect the two (in the wiring diagram) and click the “run” button repeatedly. Numbers from 0.00 to 1.00 should be displayed in the front panel

23. National Instruments Confidential22 Example 1: Craps (continued) Delete the wire Add a multiplication node and a numeric constant to allow multiplication by 5 Add an addition node and numeric constant to allow addition of 1 Add a mathematical “Round to Nearest” node. Make a second copy of this structure to represent a second die and wire them together through an addition node with an output to a numeric constant This wiring diagram simulates the rolling of 2 dice and their addition to form a number from 2 through 12.

24. National Instruments Confidential23 MyDAQ

25. National Instruments Confidential24 MyDAQ - Designed for hands-on experimentation. NI MyDAQ combines portability with a comprehensive set of features. NI MyDAQ allows for real engineering and, when combined with NI LabView and Multisim, gives students the power to prototype systems and analyze circuits in or outside of the classroom. NI MyDAQ hardware integrates with NI Labview graphical development software, giving the students hands-on interaction with real analogue circuits, sensor measurements, and signal processing. It bridges the gap between theory and real-world practice by providing students with eight Labview software-based instruments including a digital multimeter (DMM), oscilloscope, function generator, bode analyzer, dynamic signal analyzer, arbitrary waveform generator, digital reader and digital writer. NI MyDAQ is compact enough to fit in a student's pocket, and is powered by a USB connection.
