Communicating with Eternal C++ Project using QT Widgets Application
Ghaas last edited by
I am an intern at NASA Ames Research Center, I am a EE Student and fairly new to coding.
I have created a QT GUI already that plots battery voltage as read from the raspberry pi in real time. I have been tasked to also plot the output of an external c++ project into this GUI. This project https://github.com/nasa/GSAP is created using Cmake. Once built, the application is started by running an executable from the linux command line. It then saves this output that I need to plot into a text file. Since reading from a text file is inefficient. I was wondering what the best way would be to include this project into my GUI application, so that I could plot the value directly instead of the application printing to a text file and then reading from there. I was looking into QProcess as a means to run a shell scrip that would start the application, but I am unclear of a good means to incorporate this value into the GUI from the stored variable location. Any help or suggestions would be appreciated.
Hi and welcome to devnet,
You should take a look at the various IPC options provided by Qt.
