Plug in the RP2040 feather to your computer. Next, hold down 'boot sel' button and press the 'reset' button (while holding 'boot sel'). Release 'boot sel' and the RP2040 feather should appear as a USB flash/thumb drive. Copy the .uf2 file in this directory to the drive. The RP2040 feather should reset and reappear as a drive with a 'code.py' file and a 'libs' directory. Copy the files in the 'libs' directory in this directory (the 'neopixel.mpy' and 'adafruit_pixelbuf.mpy' files) to the 'libs' directory on the RP2040 feather.
You should now be ready to load any of the examples for this workshop onto the RP2040 feather!
