DAQmx DO Write Output Buffer before Start Task

[Quiztus2]

Hi,

I want to write the output buffer before starting the daqmx DO task.

Can I do it somehow similar to the snippet?

Or should I Configure Software Trigger, Start,Write, Fire SW Trigger?

But you are creating an analog input task from your snippet.

If you are using a sample clock-timed digital output task, yes you should write some data before starting the task. You can refer to the shipping examples.
