Raspberry Pi Pico
Setting Up For MicroPython
Install Or Update Thonny
Thonny is a free software IDE (Integrated Development Environment) for Python. It has extensions that allow you to work with microcontrollers.
If you are using a Raspberry Pi with a recent version of the Raspberry Pi OS, you will already have Thonny installed. You can update it with a terminal command - open a terminal with CTRL+ALT+T and then type,
sudo apt update && sudo apt upgrade -y
This will ensure that you are using the latest version in the Raspberry Pi repositories.
For Windows, Mac or Linux, go to the Thonny web site at https://thonny.org/ and download the appropriate installer.
