* MicroPython on STM32

* To update/modify software on STM32 board:
** Connect your computer to the CN5 connector (mcro-USB Type B).
** You should have access to the flash of the STM32 board (on my computer a  mountpoint called "PYBFLASH" is created).
** Put files of your new software.
** That's all


* Architecture of a (u)Python software:
** You need a main file "boot.py" which is read on boot-up.
** The "boot.py" file must be, in general, minimalist. For example:
--
import pyb
pyb.main('my_super_software.py')
--
In the example, "boot.py" run the file "my_super_software.py"
** Your software can be, as your convenience, composed of several files.

* You can access to a uPython prompt (start/stop program, see error...).
On Linux: use the command: "screen /dev/ttyACM0"
On other system: use Google or whatever, I don't care.
