[Realtime data consumption of a C++ program]

Hi @matt.casavecchia

You can use the Tool.exec or .start functions to launch an external application, see the Help in the app

You can also use the WF SDK/API and for linking use -ldwf, see the manual and examples

@attila I'm having trouble extracting data from the "rgwSample" variable on the C++ example "DigitalIn_record.cpp".

I'm measuring a 1Hz square wave on DIO0. 

Ideally i'm trying to see when the digital input switches from 0 to 1. I have it set to take 100 samples at 10Hz... The program returns immediately with only rgwSamples[0] through rgwSamples[6] filled in. Can you help shed some light on how to use this variable properly & how to figure out what time these measurements were taken at. 

[Realtime data consumption of a C++ program]

Right now I'm trying to consume digital Input measurements and use them in a C++ (Linux) application. 

Currently, I'm writing to file from the Waveforms application. Then running the c++ application which reads from the file which waveforms is writing to. Is there a better way to do this? Any Ideas would be appreciated .

if there is a way for waveforms to send udp packets that might also work for this application... 

 

EDIT: I see there's a way to do this with the sdk but I'm having trouble linking the library with CMAKE. Has anyone used CLION+CMAKE with this dwf dynamic library?
