Embedded python: How to debug code in an isolated way

[Schachner, Joseph]

Another suggestion:  If your Python code only references  few things outside of itself, make a simulated environment in Python on your PC, so that you can run your embedded code after importing your simulated environment, which should supply the functions it expects to call and variables it expects to access.

Then you can use any PC based debugger (PyScripter, Jetbrains' PyCharm, Visual Studio with Python support, etc) to debug in the simulated environment.

Yep.  Even if you have to bit-bang a tx-only UART on a GPIO pin.

I've had to do that many times, and the last time was only a couple years ago.  Though I must admit I never had to do that _in_ Python or on a platform capable of running Python...
