A simple way to 'remote' control a micro:bit from Python on a PC/Mac/Pi/Linux
This was some work that I did in August 2015 when MicroPython was first ported to the micro:bit
In it's current state it is now out of step with the MicroPython API, but the concept is sound and it could easily be developed into a working solution again.
The way I did this was to create a microbit module that you import on the PC/mac/pi/linux like this
import microbit
And then for each micro:bit feature, the PC version would send the appropriate REPL to MicroPython running on the micro:bit, it would 'do it's stuff' and return the result.
So, writing this on the PC
import microbit import time
while True:
x = microbit.accelerometer.get_x()
y = microbit.accelerometer.get_y()
print("pos %s %s" % (x, y))
time.sleep(1)
The bulk of this loop runs on the existing installed python on the PC. When it calls microbit.accelerometer.get_x() it sends a message to the micro:bit REPL to get the x acceleration, it returns the value, and that is assigned to the x variable in the python running on the PC.
So, the micro:bit just becomes a sort of remote sensing device.
microbit.display.scroll("hello world")
Running this on the PC would scroll Hello World on the micro:bit display.
The micro:bit MicroPython API has changed quite a lot since I first wrote this, but if this is what you are talking about, I could upload the code to github and someone else could help me update it to the latest API :)
It probably only works with python 2 at the moment and will need some love to make it python 3 compatible.
Note that a version of pyserial is embedded inside this project, as allowed by the licence agreement from pyserial. This is so that you don't have to install any dependent packages. The microbit.py module can be configured to use the embedded pyserial or the installed one in the dist path by changing a flag in the file.
pyserial 2.7 (python licence) comes from here:

The anyio package is something I wrote to make it possible to use an Arduino on PC/Mac/Linux to simulate the Raspberry Pi RPi.GPIO features, to allow GPIO projects to be written that work on any platform.
