I am following this guide which seems to be excllent, except for one litte problem:
When I debug, a breakpoint which I set on the first line is nor reached and the script seems to hang.
The debugger tabs shows that we are connected:

The command line shown in the console tab is
G:_Python\BBC_microbit\demo\venv\Scripts\python.exe "E:\coding\Python\PyCharm Community Edition\helpers\pydev\pydevd.py" --multiproc --qt-support=auto --client 127.0.0.1 --port 12153 --file G:/_Python/BBC_microbit/demo/demo.py
Any idea how I can get it to hit the breakpoint?
