do i have the buffer in the right place

[Dennis_Knutson]

Personally, I think it's s bad design to request a sample count that is greater than the samples per second. I would put the read inside a loop. With such a high number of samples, your gui becomes unresponsive. Try it and see if the error goes away.

oh so you would need to multiply your timeout by the sample rate to get the exact number of samples you need before it times out.

[Dennis_Knutson]

No. The default timeout is fine. The default buffer is fine.

[reggie2016]

right now i am getting a million samples but i only need 324000.

[Dennis_Knutson]

Another problem with your arithmetic?

[reggie2016]

im just not sure what im doing.

[Dennis_Knutson]

I'm totally unsure of what you are doing now. Can you attach an image of your block diagram?

[reggie2016]

how do you do that.

[reggie2016]

Ok, let's take a step back.

What exactly are you trying to do with this VI?  There is a lot happening on your VI that likely just doesn't need to be there and it will help things A LOT if we do some cleaning up.
