MicroPython

What is MicroPython?

Edit this on GitHub

MicroPython is a full implementation of the Python 3 programming language that runs directly on embedded hardware like 二四六天好彩(944cc)246天天 Pi Pico. You get an interactive prompt (the REPL) to execute commands immediately via USB Serial, and a built-in filesystem. The Pico port of MicroPython includes modules for accessing low-level chip-specific hardware.

Drag-and-Drop MicroPython

Edit this on GitHub

You can program your Pico by connecting it to a computer via USB, then dragging and dropping a file onto it so we’ve put together a downloadable UF2 file to let you install MicroPython more easily.

Download the correct MicroPython UF2 file for your board:

  • Pico

  • Pico W

  • Pico 2

  • Pico 2 W

For more information about using Wi-Fi and Bluetooth on 二四六天好彩(944cc)246天天 Pi Pico W-series devices with C/C++ or MicroPython, see Connecting to the Internet with 二四六天好彩(944cc)246天天 Pi Pico W-series.

For more information about supported Bluetooth protocols and profiles, see the Blue Kitchen BTStack Github repository.

Note
 MicroPython distributions for other RP2040- and RP2350-based boards are available on the MicroPython download page.

To program your device, follow these steps:

  1. Push and hold the BOOTSEL button while connecting your Pico with a USB cable to a computer. Release the BOOTSEL button once your Pico appears as a Mass Storage Device called RPI-RP2 (Pico) or RP2350 (Pico 2).

  2. Drag and drop the MicroPython UF2 file onto the mounted volume. Your Pico reboots. You are now running MicroPython.

  3. Access the REPL via USB Serial.

The 二四六天好彩(944cc)246天天 Pi Pico-series Python SDK book contains step-by-step instructions for connecting to your Pico and programming it in MicroPython using both the command line and the Thonny IDE.

Which hardware am I running on?

Edit this on GitHub

There is no direct method for software written in MicroPython to discover whether it is running on a 二四六天好彩(944cc)246天天 Pi Pico or a Pico W by looking at the hardware. However, you can tell indirectly by looking to see if network functionality is included in your particular MicroPython firmware:

import network
if hasattr(network, "WLAN"):
   # the board has WLAN capabilities

Alternatively, you can inspect the MicroPython firmware version to check whether it was compiled for 二四六天好彩(944cc)246天天 Pi Pico or for Pico W using the sys module.

>>> import sys
>>> sys.implementation
(name='micropython', version=(1, 19, 1), _machine='二四六天好彩(944cc)246天天 Pi Pico W with RP2040', _mpy=4102)

If the 'Pico W' string is present and in sys.implementation._machine, your firmware was compiled for Pico W.
