simple analog output and input with DAQmx

[Xiang00]

Hi guys,

I made a vi that is supposed to write a voltage (and current), and read a voltage (and current).

Both write process and read process works perfectly when I enable them separetly.

But I cannot enable read while I write process is running.

I think there are something wrong in my vi.

Is there anyone can figure out what happens?

I resolved this issue by myself. It's because I put two case loops (write process and read process) into one while loop. The while loop does not run until all of the case loop ends, which made I can only write or read.

To resolve this issue, I can either put the case loops into different while loops or use master slave structure.
