What is the maximum value for "wait" in the FGEN script?

[Joji]

In the script editor for FGEN, you can specify a 'wait' in 'samples' to pause the generation.  If you use a finite (not HW Trigger), how long can you wait?  Is the wait # limited to a U32?  If so (and assuming you were running at 20MHz), you could wait 2^32/20M=214s.  Correct?

[Drew Creel]

The wait is limited to a U32, but the limit is in bytes rather than samples.  So the actual equation for the maximum wait time is (2^31 -1)/Sample Rate, or about 107s for your example (FGEN devices use 2 bytes per sample).  However, that's just the limit for one wait; you can create a script with multiple wait statements if you need a longer wait time, like this:

script waitScript

   wait 2000000 

   wait 2000000

   wait 2000000 

   <etc.>

end script
