⚡️ Quick Tips and Facts
Before we get our hands dirty with the source code, here are some “byte-sized” facts about the MicroPython GitHub ecosystem:
- ✅ Main Repository: micropython/micropython
- ✅ Primary Language: C (approx. 90%), with Python and C++ making up the rest.
- ✅ Creator: Damien George, a physicist who clearly decided that standard Python wasn’t portable enough.
- ✅ Stars: Over 18,000 (and counting!).
- ✅ License: MIT License—meaning you can use it for your top-secret world-domination robot without paying a dime.
- ❌ Don’t confuse it with: CircuitPython (a fork by Adafruit) or CPython (the “big” Python you run on your PC).
- 💡 Pro Tip: If you want to save RAM on your microcontroller, use the
mpy-crosstool to pre-compile your.pyfiles into.mpybytecode!
📜 The Genesis of MicroPython: A GitHub History Lesson
Back in 2013, Damien George launched a Kickstarter campaign that would change the lives of embedded engineers forever. He wanted to run Python on a microcontroller. People laughed. They said, “Python is too slow!” “It uses too much RAM!”
Damien didn’t listen. He wrote a highly optimized implementation of Python 3 that could run in just 256KB of code space and 16KB of RAM. The first commit on GitHub was the beginning of a revolution. Since then, the repository has seen thousands of commits, evolving from a niche project for the Pyboard to the industry standard for rapid prototyping on chips like the ESP32 and Raspberry Pi Pico.
We remember the early days when getting a Wi-Fi connection on an ESP8266 felt like magic. Today, thanks to the tireless contributors on GitHub, it’s just two lines of code. 🪄
📂 Navigating the MicroPython Repository: Folders, Files, and Hidden Gems
When you first land on the MicroPython GitHub page, it can look like a labyrinth. Here’s your map:
| Folder/File | What’s Inside? | Why You Should Care |
|---|---|---|
py/ |
The Core VM | This is the “brain.” It contains the compiler, runtime, and garbage collector. |
ports/ |
Hardware Specifics | This is where the magic happens for specific chips (esp32, stm32, rp2, etc.). |
lib/ |
External C Libs | Contains third-party libraries like mbedtls for security and lwip for networking. |
docs/ |
Documentation | The source for the official MicroPython docs. Read it! |
mpy-cross/ |
Cross-Compiler | The tool that turns Python scripts into bytecode. |
tests/ |
Test Suite | How the devs ensure they didn’t break your code with the last update. |
Latest Commit & History: You can always see what the team is working on by checking the “Latest commit” at the top of the file list. Whether it’s a fix for the Raspberry Pi Pico W Bluetooth stack or an optimization for the garbage collector, the history is a goldmine of engineering wisdom.
🚀 Getting Started: Cloning and Compiling Your First Firmware
You don’t just “use” MicroPython; you experience it. While you can download pre-compiled binaries from the MicroPython downloads page, true “Robotic Coding™” experts build their own.
- Clone the Repo:
git clone --recursive https://github.com/micropython/micropython.git(Don’t forget--recursive! MicroPython uses submodules for its external dependencies.) - Build mpy-cross: Navigate to
mpy-crossand runmake. You’ll need this to compile the core. - Choose Your Port: Go to
ports/esp32(or your chip of choice). - Compile: Run
make. If you have the ESP-IDF installed correctly, you’ll get a.binfile ready to flash.
Warning: Compiling firmware for the first time is a rite of passage. You will run into dependency issues. You will forget to set your PATH. But when that “Hello World” finally blinks an LED? It’s pure euphoria. 🌟
🏗️ Supported Platforms & Architectures: From ESP32 to Raspberry Pi Pico
MicroPython isn’t picky. It runs on a staggering variety of silicon. Here are the heavy hitters you’ll find in the ports/ directory:
- STM32: The original home of MicroPython. High performance, very stable.
- ESP32 & ESP8266: The kings of IoT. If it has Wi-Fi and costs $5, it’s probably an ESP32.
- RP2 (Raspberry Pi Pico): The new kid on the block. The Raspberry Pi Pico is cheap, powerful, and has amazing MicroPython support.
- nRF52: Great for Bluetooth Low Energy (BLE) projects.
- MIMXRT: For when you need insane speeds (up to 1GHz!) on a microcontroller.
⚙️ The MicroPython Cross-Compiler: Mastering mpy-cross
Why would you want to cross-compile? Because microcontrollers are like tiny apartments—they have very little “closet space” (RAM).
When you run a .py file, MicroPython has to compile it to bytecode on the chip. This consumes RAM. By using mpy-cross, you do that work on your powerful PC. You upload a .mpy file, and the chip just runs it. It’s faster, leaner, and makes you look like a total pro. 🕶️
📦 The micropython-lib Deep Dive: 20 Essential Libraries You Need
The main repo is the engine, but micropython-lib is the interior, the GPS, and the heated seats. It contains ports of standard Python libraries. Here are 20 you should know:
- os: File manipulation and directory handling.
- time: Essential for delays and timestamps.
- json: For parsing API responses.
- requests: (via
urequests) The bread and butter of IoT web calls. - machine: The most important lib for hardware control (GPIO, I2C, SPI).
- network: Managing Wi-Fi and Ethernet connections.
- umqtt.simple: For talking to MQTT brokers like Mosquitto.
- uasyncio: For writing non-blocking, asynchronous code.
- math: Standard mathematical functions.
- struct: Handling binary data.
- binascii: Converting between binary and ASCII.
- hashlib: For SHA256 and other cryptographic needs.
- random: Generating pseudo-random numbers.
- re: Regular expressions (yes, even on a chip!).
- collections: Named tuples and deques.
- errno: Standard error codes.
- heapq: Heap queue algorithms.
- zlib: Data compression.
- logging: For when print statements aren’t enough.
- unittest: Because even robot code needs testing!
🤝 Joining the Robot Revolution: Contributing and Sponsoring MicroPython
MicroPython is open-source, but it isn’t “free” to make. It takes thousands of hours of expert engineering.
- Contributing: Found a bug? Open an Issue. Fixed a bug? Submit a Pull Request (PR). The maintainers are strict about code quality (they love their coding style!), so read the
CONTRIBUTING.mdfile first. - Sponsoring: You can Sponsor this project directly on GitHub. If your company uses MicroPython to make money, it’s only fair to kick some back to Damien and the team. 💸
💎 About This Repository: Releases, Packages, and Languages
The “About” section on GitHub tells a story of a mature project.
- Releases: MicroPython follows a steady release cycle. Always check the Releases tab for the latest stable version before starting a new project.
- Packages: With the introduction of
mip(MicroPython Install Package), managing libraries is easier than ever. It’s likepip, but for the small guys. - Languages: While the core is C, the ecosystem is built on Python. This “dual-citizen” status is what makes it so powerful.
🔍 Pro Tips: Using Saved Searches to Filter Results Like a Ninja
The MicroPython GitHub has thousands of issues. Don’t drown in them! Use saved searches to filter your results more quickly.
- Want to see only ESP32 bugs? Search:
is:issue is:open label:port-esp32 - Looking for “good first issues” to start contributing? Search:
is:issue is:open label:"good first issue"
We use these filters daily to see if a weird bug we found is a “me problem” or a “MicroPython problem.” (Usually, it’s a “me problem,” but hey, we can dream!)
🔗 External Dependencies and Submodules: Keeping it Clean
MicroPython doesn’t reinvent the wheel. It uses External dependencies like axtls or berkeley-db. These are managed via Git submodules.
❌ Common Mistake: Downloading the ZIP of the repo from GitHub. This won’t include the submodules, and your build will fail faster than a robot in a rainstorm. ✅ Correct Way: Always use git clone --recursive.
🏁 Conclusion
The MicroPython GitHub repository is more than just code; it’s a testament to what happens when you combine the elegance of Python with the raw power of embedded systems. Whether you’re a hobbyist building a smart plant waterer or a professional engineer designing industrial sensors, this repo is your best friend.
So, what are you waiting for? Go clone the repo, flash your ESP32, and start building something awesome! And remember, if your code doesn’t work on the first try… it’s probably just a missing semicolon in the C core. (Just kidding, Python doesn’t use semicolons—that’s why we love it!)
