Roy,
If you run your code, but do not give a trigger, does it
timeout? (it should) And are any samples written? (no new samples should be
written) Does all of this behavior happen the same if you use a rising edge
trigger?
I would like to ask that you post a screen shot of your
scope, showing the trigger and output signal, so that I can see the incorrect
signal being produced before the trigger happens.
