What is MicroPython?

MicroPython is a full implementation of the Python 3 programming language that runs directly on embedded hardware like Raspberry Pi Pico. You get an interactive prompt (the REPL) to execute commands immediately via USB Serial, and a built-in filesystem. The Pico port of MicroPython includes modules for accessing low-level chip-specific hardware.

Prepared knowledge

Pico and Thonny basics (Important):
If you don’t have Pico and Thonny basics, you can follow the link to learn the basics:

  1. Learn about Pico briefly.

  2. Using MicroPython in Thonny.

  3. Upload the code to Pico.

MicroPython for Pico.

Upload code to Pico

Tools:

  1. PC(Win10 or uper)

  2. Micro USB cable

Download code:
Please download the code on Github:
https://github.com/Mosiwi/Mosiwi-space-station-kit-for-pico

Upload module and main code:
Make sure your Raspberry PI Pico’s USB is plugged into your computer’s USB via a usb cable, then click on “Python” and the version number in the bottom right corner of the Thonny window, then select “MicroPython(Raspberry PI Pico)”. COMx “.

Tip

If you save a file to the Pico and give it the special name main.py, then MicroPython starts running that script as soon as power is supplied to Raspberry Pi Pico in the future.
