what the best way to start labview.
can it be used for embedded controller like 89C51, PIC16F, MSP430G2553.

 

Labview is generally used to control various types of test instrumentation and make virtual test sets with a PC to perform dedicated tests of production electronic hardware. For example I worked on a space program where they performed all the system tests of the satellite using a PC controlled test set programmed in Labview.

For programming embedded controllers, C or Assembly is usually used (although some old die-hards like me prefer Basic for hobby applications).

 

This might be of interest ..
