Can not stop the scope about deviceinterface

[louiecaulfield]

First off, you don't need to use Application.DoEvents() since you're using a windows forms app. This is only necessary for console apps (on windows).

Secondly, I don't see you using IScope.GetScopeData() anywhere, nor are you using the IScope.DataSourceScope (which calls GetScopeData() in its own thread). You need to call this method, otherwise the software doesn't know what state the scope is in.

Thanks, the only other issue I have is setting the view port to match my scope set up. Thanks again. George Please excuse fat finger mis-spellings

I believe the UI reports a different viewport offset than the one used in the API. Check the source:

        public void SetViewPort(double offset, double timespan)
        {
            /*                maxTimeSpan
             *            <---------------->
             *  .--------------------------,
             *  |        ||       ||       |
             *  `--------------------------`
             *  <--------><------->
             *    offset   timespan
             */

If you don't care about the viewport vs acquisition window, best is to set offset to 0 and timespan to AcquisitionLength.

I wish to thank you all for the help, I am capturing my event and on my way, getting all the math right. Doing RMS on the samples. It would be nice to have an automatic "Delete Double Value" when working at a relatively slow 43ms you end up with a lot of doubles

Thanks again,
George

What do you mean with "double value"?

Can you describe the inconvenience?

[gjzamiar]

Not double value, like you have the average math, it would be nice have an RMS math function. George Please excuse fat finger mis-spellings

I don't understand what you're asking. Are you referring to the SmartScope app's measurements? Or features of the DeviceInterface library?

Average() is a built-in function of C# (or to be more precise, Linq).

If you're trying to calculate the RMS and don't want to write the code yourself, I suggest you just google and copy paste a few lines of code

This question has nothing left to do with the original topic of this issue, so I'm closing it. Feel free to open new ones if you have more issues.
