Install CircuitPython

Raspberry Pi Pico

Download the latest release.

If the RPI-RP2 drive doesn't automatically appear when the Pico is connected to the PC, hold down the BOOTSEL button, and while continuing to hold it, plug the Pico into USB. Continue to hold the BOOTSEL button until the RPI-RP2 drive appears.

Drag the adafruit_circuitpython_etc.uf2 file to RPI-RP2. The RPI-RP2 drive will disappear and a new disk drive called CIRCUITPY will appear.

Write some code in /media/francois/CIRCUITPY/code.py. If it doesn't run on file saving, press ctl-D.

"""Example for Pico. Blinks the built-in LED."""
import time
import board
import digitalio
 
led = digitalio.DigitalInOut(board.LED)
led.direction = digitalio.Direction.OUTPUT
 
while True:
    led.value = not led.value
    time.sleep(0.5)
