Instrumentation Laboratory Exercise 33
As the digitization process takes time (in this case 200 ms), we must
wait for the data to be read before we can display it so we will have
to include the following loop which waits for completion of the
digitization.
First we need to add another Until Break loop. It is fed from the
bottom of the first Direct I/O box. Its output (right side square) is
connected to another Direct I/O box which queries the DAQ device to
see if the digitization process has been completed. To do this you
must enter 2 lines into this second Direct I/O box:
1 "WAV:COMP?" // Asks if the digitization
is complete
2 READ TEXT x STR // Reads the answer in
TEXT form into the
variable x
