Hello,

I want to know if it was possible to read data from USB device without using the DEWESoft software.

Thank you

Hi,

I'm assuming that you'd like to read data from DEWESoft files without actually having DEWESoft installed on that PC? DEWESoft offers the ability to read data into several third party programming environments (MATLAB for example). This functionality is called DWDataReader and all of its files are located in the developers section of the webpage, but you need to be logged in to be able to see them.

Thank you for your answer.

I already tried using the DWDataReader library. I wish to read directly from the USB device instead of the file.

Hi,

so you would like to read data from our USB devices, but not with DEWESoft software? I don't think there's a way to do that, but you can use DCOM applications to automatize the data acquisition process or to control the acquisition via third party software, but everything still goes through DEWESoft. All of it's documentation and examples can also be found in the developers section.

Thank you so much.

I developed a plugin in C ++ and now I access to direct capture buffer. Is it possible to read the FFT result?

I read the list of channels and the data of the analog inputs are consistent. The size of the buffer and the data type of the other channels are not consistent. The code of datatype of the incosistent channels is 5, in documentation there isn't this code.

Thanks a lot.

Hi,

I have study the documentation and the datatype 5 is a "Single" value. I can not read the result of FFT from direct buffer.

How can I read the FFT information?

Thank you
