Getting Started#

MicroPython is a version of the Python programming language designed for use on microcontrollers like the ESP32, STM32, RP2040, etc. Installation instructions are available from the micropython.org Quick Reference page for each microcontroller (sidebar links from the Documentation page), which is generally: downloading the distribution file and installing it over a USB connection.

Note that MicroPython on a microcontroller has what's effectively its own tiny file system (as a "Pyboard"), and there's not really much in the way of standardisation of how things are installed there. So if a library or function isn't defined in MicroPython itself (or, e.g., in Pimoroni's distribution of it), you can simply install the necessary files on your microcontroller, perhaps in its own or a 'lib' directory, and just be sure to manage your imports so your main.py can see the necessary files. It's not a lot more complicated than that.

I'd also recommend rshell, which provides a command line into /pyboard where you can use commands like cp (copy), df (get filesystem info), rm (delete files), rsync (synchronise with a local directory), and edit (with vim being the default editor, but changeable). repl provides access to the Python REPL so you can execute your code. Highly recommended. The `rsync` feature alone is worth it, e.g., you can sync your installation with a local directory that can be maintained on github.
