→La LED heartbeat
== La LED heartbeat ==
== La LED heartbeat ==
By default the heartbeat LED flashes once every 4s to signal that the system is alive. This can be overridden through the {{fname|wipy}} module:
<nowiki>>>> import wipy
>>> wipy.heartbeat(False)</nowiki>
There are currently 2 kinds of errors that you might see:
# If the heartbeat LED flashes quickly, then a Python script (eg {{fname|main.py}}) has an error. Use the REPL to debug it.
# If the heartbeat LED stays on, then there was a hard fault, you cannot recover from this, the only way out is to press the reset switch.
