How to flash micropython on ESP-WROOM-32

YOU’LL NEED

• This version of the installer.
• A tar.gz file that contains a valid firmware upgrade (see links bellow).
• Python 2 with pyserial installed.
• Find out the name of the serial port you’ll be using:

Windows use a COM# (where # is a number) MacOS will use something like /dev/tty.usbserial-XXXXXXXX (where XXXXXXXX is a value specific to your expansion board). > For Pytrack/Pysense this is /dev/tty.usbmodemPyXXXXXX Linux will use something like /dev/ttyUSB# (where # is a number). For Pytrack/Pysense this is /dev/ttyACM# instead. You can > use the following command as well:

# inside the script we should have something like below:
def run(*script_args):  
    print (script_args)
    
# from the shell when calling the script to run use the --script-args to pass in arguments and they will be recieved as tuples inside the script

#-> example: python manage.py runscript myscript --script-args Testing 123
will return ('Testing','123')
