Flashing

The flash.sh script can be used to upload firmware to the ESP8266. It will copy all the files in the current directory with the ".py" extension to the board's memory. It also removes all comments and empty lines from these files before uploading to space memory space.

Usage:

./flash.sh [SERIAL PORT]

Example usage: ./flash.sh /dev/ttyUSB0
