To use the Code Editor, you will need an internet browser such as Google Chrome or Microsoft Edge. It's possible that it may work in other browsers as well, but these ones have been more thoroughly tested.
Open your browser and navigate to https://code.circuitpython.org/. Select USB on the dialog prompt that comes up.
This will display a page of instructions along with a button to bring up a list of devices to connect to.
At this point, if your device does not have a CIRCUITPY drive or it is disabled, it should now be connected.
Devices with a CIRCUITPY Drive
Devices with a CIRCUITPY drive will need a few additional steps because as the File System is mounted read-only for the REPL.
You will then need to select a Host Folder, which should be your CIRCUITPY drive unless you have renamed it.
It may ask permission to edit the files in the location that you selected. Choose Edit files. This will allow the editor to read and write files.
Alternatively, you may get a dialog that asks if you want to allow CircuitPython to Edit files. You can click Allow this time if you'd like to be presented with the dialog each time or Allow on every visit if you would rather not be asked.
If you are happy with the location that you selected, choose Use [Folder Name] where [Folder Name] is the name of the folder you selected. Otherwise you can choose Select Different Folder.
