Hi Yun,

1) You should type a descriptive title for your post and put the "main" text into the post. Putting the text into the title is annoying...

2) You should init the task before the loop and de-init after the loop. No need to do this with every iteration!

3) When trying to output an array of values you should use a FOR loop instead of the while loop and use the autoindexing feature of the loops to get the actual values from the input array...

Thank you!

could you give me an example?

Hi Yun,

here I don't have DAQmx installed. But there are several examples to look at when using the Example finder in the help menu of LabVIEW!

I have seen those examples.But,I still have no idea to solve my problem.

Yun,

Here's a simple example I wrote that does what you are trying to do. You can wire an array into an Analog Out 1D DBL 1 chan N Samples. Then I wired the size of the array into the number of samples per channel on the timing vi.
