Installing Mu

Editor

Mu is a simple code editor that works with the Adafruit CircuitPython boards. It's written in Python and works on

Windows, MacOS, Linux and Raspberry Pi. The serial console is built right in so you get immediate feedback from your

board's serial output!

Download and Install Mu

Download Mu

from https://codewith.mu (https://adafru.it/Be6). Click

the Download or Start Here links there for downloads

and installation instructions. The website has a wealth of

other information, including extensive tutorials and and

how-to's.

Using Mu

The first time you start Mu, you will be prompted to

select your 'mode' - you can always change your mind

later. For now please select Adafruit!

The current mode is displayed in the lower right corner

of the window, next to the "gear" icon. If the mode says

"Microbit" or something else, click on that and then

choose "Adafruit" in the dialog box that appears.

Mu is our recommended editor - please use it (unless you are an experienced coder with a favorite editor

already!)
