The developer was very helpful in helping me debug some issues with installing bitlib and bitscope on my RPi4 using Python3.
For installing bitlib on Python 3, first install the corresponding source package from Trello: https://trello.com/c/WQdjoFbq/32-%E2%86%AF-fe26b-bitscope-library-20.
For installing bitscope using pip, use the following syntax: pip install bitscope==0.0.3
