The safest way when something gets stuck in complex systems, to lay bare the basic system function, in this case test communication between LabView and Arduino using the LIFA. Therefore, here I present a simple LIFA program LED-on / off (LED on pin 13). Arduino LIFA Firmware is stripped to the basic function, synchronization with LabView, parsing commands and control digital outputs. Previously should check whether VISA is active (open Measurement & Automation Explorer -> Device and Interfaces -> Serial & Parallel -> COMs) then the Device Manager -> Ports -> Arduino COMx. The included program Base8.ino should load in the Arduino (UNO) as any sketch. Run supplied program SimpleLED2.vi. previously entering Arduino's COMX.Pushing the key should alternate LED13 (on / off).
