Hello labview programmers !
After i realized that visa read function is polling the port thus stucking my code i looked how to use visa events.
I did exactly as the shipped examples showed, but the visa events acts like polling - it hangs the front panel and stucking other
loops in my program to run properly. i looked at cpu consumption stats and it was ok - 3%.
what could be the problem ?
Go to Solution.
I figured it out !
In the properties of the vi -execution - execution system - the value was set by me by mistake to user interface.
visa events and visa functions works bad in this mode !!!
I switched it to same as caller and it finally solved my problem !
