Setting up our Circuitpython toolchain

+ +
+ + +
+

Step 1: Setting up the IDE

+

There are many IDEs that we can use to program CircuitPython robot, we can even just use a text + editor.

+

However we'll be using one called "Mu Editor". So let's begin by downloading it.

+

Download

+ +

You can also get it from the Mu website, https://codewith.mu/en/

+
+
+ +
+ + +
+

Step 2: Install Circuitpython on board

+
    +
  1. Download the CircuitPython firmware UF2 file for the RP2040 Zero here.
    2. +
  2. Connect your RP2040 Zero to your computer using a USB cable.
    3. +
  3. Hold down the BOOT button, press and release the RST button.
    4. +
  4. A new USB drive appears in your file explorer called RPI-RP2.
    5. +
  5. Drag the downloaded CircuitPython firmware file into the RPI-RP2 drive.
    6. +
  6. The firmware will install, and after a moment, the drive should be called CIRCUITPY. +
    7. +
  7. Open the drive and examine the different files in there. The "code.py" file is our main + file, but we won't open it here.
    8. +
  8. Open the MU Editor, and we can start coding!
