====== Log Micropython console text to file ======
Here is a small snippet, how you can write everything what you get on console to file in your Micropython device. This may help you to debug long running devices.

<code python>
import io, os

class logToFile(io.IOBase):
    def __init__(self):
        pass

    def write(self, data):
        with open("logfile.txt", mode="a") as f:
            f.write(data)
        return len(data)

# now your console text output is saved into file
os.dupterm(logToFile())

# disable logging to file
os.dupterm(None)
</code>
