Why I use Serial communication in LabView it will run like a loop but I don't create a loop

I don't see where you are saving data.

Check to see if the number of bytes equals zero and use that to drive a case structure where you either do save or don't save your data.

I try to add an resgister to save the data but I have a problem. When the period is less than the delay time I send from my PIC. the data receive will equal 0. I can not save the data when it do that.

Can you help me to fix that

You have not done a single thing that I suggested. That shift register makes no sense to me. What do you think it is supposed to do?

Sorry I am new with LabVIEW.

I can save the data when I use the local variable. But I don't want to use this. Can you help me another way to store and display the data when the period is less than the delay time my PIC send ( the data will be zero if the period is less than the delay time ).

Here I try to use the shift resgister but I doesn't work.

Your shift register does not make any sense. Try this mod.

[thecone]

Your mod is great.

I reversed the table to see the new data update.

When my period is larger than the delay time data send from my PIC. How I can get only the lasted data ? (But do not use shift register or variable)

Can you help me?
