Week4 - Micropython

Micropython​

MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments.

I refer to my classmate - Hongtai's assignemnt, I choose a online tool for flashing the firmware to XIAO board.

  • choose <ESP32 COM PORT> from the dropdown menu.

  • Select the Firmware we just downloaded.

Open the serial monitor to observe the output. I use mobaXterm to connect to serial monitor.

  • Go to Session
  • Choose Serial
  • Choose the COM of the board and set the baud rate as 115200

Then, restart the board, you can see the command windows which can be inputed the command.

Write program​

We send hello fab academy to serial monitor.

import machine

while True:
    print("hello, fab academy!")
