I am trying to integrate or combine two different VI in LabVIEW. One of the VI is responsible to measure the airflow through a USB device connected to the computer. The other VI is responsible for sound acquisition through audio jack. Since I’m quite new to this LabVIEW, I tried to copy and paste the sound acquisition block diagram into the other block diagram which measures the airflow. After the insertion of the block diagram of sound acquisition into block diagram of airflow measurement, only the sound acquisition program runs and displays sound signals. But the airflow measurement was not working and even not displaying in the graph. I don’t know how to connect the sound acquisition program with the airflow measurement.
Is it copy pasting the block diagram is possible to integrate the two VI? Is there any other way to combine the two VI?
Here I attached the two different VI, the VI for airflow measurement (STtrace) and the VI for sound acquisition (microphone setup 2_listen).
Could anyone help me to solve this problem?
