Background: The Evolution of CircuitPython 📜

travel the world

CircuitPython is built upon the foundation of MicroPython, a lightweight implementation of Python designed for microcontrollers and embedded systems. MicroPython was created by Damien George, who wanted to bring the power of Python to the world of microcontrollers.

Adafruit, a well-known open-source hardware company, recognized the potential of MicroPython and decided to support its development. They collaborated with Damien George to create CircuitPython, a beginner-friendly version of MicroPython that simplifies the process of coding on microcontroller boards.

Since its inception, CircuitPython has gained popularity among educators, hobbyists, and professionals alike. Its user-friendly design and extensive library support have made it a go-to choice for those looking to experiment with coding on microcontrollers.

CircuitPython offers a range of features that make it an excellent choice for beginners and experienced coders alike. Let’s take a closer look at some of its key features:

1. No Upfront Desktop Downloads Needed ✨

Unlike some other programming languages, CircuitPython doesn’t require you to download and install any additional software on your desktop before you can start coding. All you need is a compatible microcontroller board and a text editor, and you’re ready to go!

2. Quick and Easy Code Editing and Execution ⚡

With CircuitPython, editing and executing code is a breeze. You can simply connect your microcontroller board to your computer via USB, and it will appear as a USB drive. You can then open the code file on the microcontroller board using a text editor, make changes, and save the file. The changes will be immediately reflected on the microcontroller board, allowing you to see the results in real-time.

3. Beginner-Friendly Design for Educational Purposes 🎓

CircuitPython is designed with beginners in mind. Its simplified syntax and user-friendly interface make it easy for anyone to get started with coding. Whether you’re a student learning the basics of programming or an educator teaching a coding class, CircuitPython provides an accessible and engaging platform for learning.

4. Easy Code Updates and File Storage 💾

Updating your code on a microcontroller board can be a hassle with some programming languages. However, CircuitPython simplifies the process by allowing you to update your code by simply copying and pasting the new code file onto the microcontroller board. This makes it easy to iterate and experiment with different code versions.

CircuitPython also provides file storage capabilities, allowing you to store data and files directly on the microcontroller board. This can be useful for data logging, storing configuration files, or even creating interactive projects that require file access.

5. Serial Console + REPL for Live Feedback and Interactive Programming 🖥️

CircuitPython provides a Serial Console and a Read-Eval-Print Loop (REPL) that allows you to interact with your code in real-time. The Serial Console provides live feedback from your microcontroller board, allowing you to debug and monitor your code as it runs. The REPL allows you to execute code interactively, making it easy to test and experiment with different ideas.

6. Strong Hardware Support with Libraries and Drivers for External Components 🛠️

One of the standout features of CircuitPython is its extensive library support. CircuitPython comes with a vast collection of libraries that provide pre-written code for various functionalities. These libraries make it easy to interact with external components and sensors, such as LEDs, motors, displays, and more. Instead of starting from scratch, you can leverage these libraries to save time and effort in your projects.

Additionally, CircuitPython libraries are designed to be cross-platform compatible. Most CircuitPython libraries also work on single board computers (SBCs) like Raspberry Pi. This means you can easily transfer your code from a microcontroller board to an SBC without any major modifications.
