NI LabVIEW TM Laboratory Virtual Instrument Engineering Workbench

LabVIEW  Graphical language by icon & wire  Consist of front Panel & diagram  Virtual instrument  Interpreter language  Fast development speed  Low execution speed

LabVIEW environment Front panelBlock diagram

Basic syntax  Control, indicator, constant  Loop (for, while, case, sequence)  Array & clustor  Functions (sub vi) for loop Random # generator File IO function Array

SUB VI’s  For easy to debug and maintain  Reuse the same code in different situations

Serial port communication  Communicate with only one device  Very slow  For Long distance  For low data transfer rates
