LABVIEW BASICS MINI-COURSE Ing. Luca Baglivo, Ing. Alberto Fornaser Department of Structural Mechanical Engineering, University of Trento Email: a.fornaser@ing.unitn.it

Labview Basics Graphic programming language (GPL) like Simulink Simple calculations friendly, complex calculations very unfriendly (must use math scripts) Complex GUIs and logic are prototyped in a flash Most powerful things: Instrument management Huge ready-to-use libraries Fast prototyping, expecially for Real Time multithreading and multicore

Labview Basics Front panel and Block diagram Input output: controls and indicators Setting default values makes your life easier Array 1-D creation and management Structures: while , for , case , sequence Running a VI and debugging Exercise 1.1 Generate a commanded circular path

Labview Basics Shift registers, derivative, integration Examples : blinking led digital filter on a step input Plotting: graphs and charts Example : visualize the commanded path Exercise 1.2 Generate a sinusoid, visualize its derivative and integral

Labview Basics Create subVIs as functions Exercise 1.3 Matrices Create a subVI for the path planning and give it your own icon. Use it with input parameters. Matrices Exercise 1.4 Fit a cloud of noisy points on a line using a pseudoinverse matrix Local and global variables
