Clear buffer /flush data each program start.

[Vizi]

Hello,

Im labview newbie and im wounder if there is an any option in labview options to not use old data from buffer.
I got projet on my studies and every time i test my program i have to turn off multiple diodes..

What buffer are you talking about?

[altenbach]

Your question is way too ambiguous. What is buffering the data? Can you show us some simplified code?

(Maybe stale data is retained in an uninitialized shift register, maybe some controls are at non-default values, maybe the default values of some controls are wrong, maybe you don't correctly shut down the hardware on program close, maybe you don't initialize the code correctly on first run,  etc. etc.)

If you can do it, your program can do it even better. You just need to program it right. 😄
