@ -138,6 +138,14 @@ Behavior
- Adds a safe mode that does not run user code after a hard crash or brown out. This makes it
possible to fix code that causes nasty crashes by making it available through mass storage after
the crash. A reset (the button) is needed after it's fixed to get back into normal mode.
- Safe mode may be handled programmatically by providing a ``safemode.py``.
``safemode.py`` is run if the board has reset due to entering safe mode. USB is not
available so nothing can be printed. ``safemode.py`` can determine why the safe mode occurred
using ``supervisor.runtime.safe_mode_reason``, and take appropriate action. For instance,
if a hard crash occurred, ``safemode.py`` may do a ``microcontroller.reset()``
to automatically restart despite the crash.
If the battery is low, but is being charged, ``safemode.py`` may put the board in deep sleep
for a while. Or it may simply reset, and have ``code.py`` check the voltage and do the sleep.
- RGB status LED indicating CircuitPython state.
- One green flash - code completed without error.
- Two red flashes - code ended due to an exception.

- Re-runs ``code.py`` or other main file after file system writes by a workflow. (Disable with
``supervisor.disable_autoreload()``)
- Autoreload is disabled while the REPL is active.
- Main is one of these: ``code.txt``, ``code.py``, ``main.py``,
``main.txt``
- Boot is one of these: ``boot.py``, ``boot.txt``
- ``code.py`` may also be named``code.txt``, ``main.py``, or ``main.txt``.
- ``boot.py`` may also be named ``boot.txt``.
- ``safemode.py`` may also be named ``safemode.txt``.
