Simple file logger for Micropython

Simple file logger for Micropython. The logger reads the timestamp from the real time clock and appends a log line to the log file. Please note that the logger does not contain logic for managing the log file (like rolling, deleting old files, etc).

Example usage:

from file_logger import Logger

logger = Logger("debug", "logfile.log")
logger.info("ESP started and connected to WiFi")

This will produce the following output in logfile.log:

2019-08-14 10:20:31.911 INFO: ESP8266 started and connected to WiFi

Setting the real time clock

If the realtime clock is not set, the timestamps will start at 2000-01-01. The real time clock can be set like this:

    import machine

    rtc = machine.RTC()
    rtc.datetime(...) #array on the format (year, month, day, weekday, hours, minutes, seconds, subseconds)
