One can also use Arduino IDE to load a piece of code into a device. It works perfectly well even if this solution is more basic and doesn't allow a lot of fine tuning. Because this software is well maintained and massively used, it makes it a very good tool for quickly prototyping without detours.
- Download Arduino IDE and install it on you computer
- Find and install the Circuit Playground library with the built-in
Boards Manager - Verify the code
- Upload the code
