Hi Sangkyu,

 

sending 18 bytes at 115200 baud takes ~18*10/115200s=1.56ms, so your data should arrive not faster than that…

 

Could you change your VI like in the attached example? Just to make sure the timing information is correct?

 

(Btw. I also removed a lot of coercion dots. Why don't you use the correct datatypes for constants?)

 

Hint for improvements:

- move the calculation of the 24 bit value into your subVI. No need to do this in your MainVI…

- don't use non-latin chars in filenames. They are really annoying for all of us with a "standard" Windows using latin chars…

Best regards,
GerdW
