• Create "ui" file in Qt Designer or Qt Creator.
• Run update_MainWindow.py which runs pyuic6 -o my_file.py <file>.ui and moves imports from the bottom to the top of the file, because promoted classes happen to be imported at the bottom for some reason which was causing an error.
• See files in this folder (e.g. file_loader.py) to see how to create/connect signals and slots.

After using Vivado block design, creating a HDL wrapper for it,
and generating bitstream, this script can be used to move the 
"_wrapper.bit" and ".hwh" files to pynq.

Tested on Windows only.
