We are trying to modify the “SaveToFile” example for C++. This particular example comes with NI-scope 2.9.1 and some other versions. This example collects data from one channel and saves the output as a text file. Also, we are using NI PCI-5112 DAQ.
However, it can be modified to get data from channel 0 and channel 1 at the same time. There is a help file called “Fetching Multiple-Record Acquisitions”, which is under the NI-High speed digitizer help topics. This confirms that you can modify the code to get data from two channels and the output will be a text file where every other value is from one channel. This help file also gives some code. However, it is not very much helpful to us, please keep in mind that we have only taken a basic course in C++.
Our project is to analyze the data, however, we need to acquire the data before we can analyze. We have spent so much time trying to get the data. What we need to do is get data from both channels simultaneously and output the data as a text file.
Can anyone help us to modify the code so it can get data from both channels simultaneously? Or can anyone help as where we can get more information? Or does anyone know of any sample examples that will take data from two channels simultaneously and output the data as a text file or any other type of document.
Any help will be really appreciated, as we have spent so much time trying to acquire the data.
Thanks.
