We are developing standalone application in qt software using c++/python language. We are sending some digital data/ waveforms from hardware and that we have to see on the application. We want to know how we can interface this application with the STM hardware. For Gui and hardware communication, we are using usb communication. But we don't know which usb class we should use for the communication.
