Development Methods​

The RP2350-Zero-CM supports three programming languages: MicroPython, C/C++, and Arduino, offering flexible choices to developers. You can select the appropriate development tools and programming methods based on project requirements and personal preference:

  • Thonny IDE (Working with MicroPython): Thonny is a lightweight Python Integrated Development Environment designed for beginners and educational scenarios, now widely used for MicroPython / CircuitPython development. Its interface is simple and intuitive, featuring a built-in Python interpreter, support for serial REPL, code flashing, and debugging, with a straightforward setup process. MicroPython is easy to learn and runs without compilation, making it ideal for beginners to quickly start embedded development. You can refer to the Working with MicroPython for initial setup, which provides detailed environment configuration steps and example programs.

  • VS Code + Pico SDK (Working with C/C++): VS Code is a powerful cross-platform code editor. By installing the Pico VS Code extension, a complete C/C++ development environment can be quickly set up. This extension integrates the Pico SDK toolchain, CMake build system, flashing and debugging tools, supports graphical operations, and offers high development efficiency. C/C++ development fully utilizes hardware performance, making it suitable for projects with higher performance requirements and professional developers, and is more applicable for complex embedded applications. You can refer to the Working with C/C++ for initial setup, which provides detailed environment configuration steps and example programs.

  • Arduino IDE (Working with Arduino): The Arduino IDE is a convenient, flexible, and easy-to-use open-source electronics prototyping platform. Arduino boasts a vast global user community, offering a massive library of open-source code, project examples, tutorials, and rich library resources. These libraries encapsulate complex functionalities, allowing developers to implement various features quickly without delving into low-level details. It is very suitable for rapid prototyping and verification, significantly shortening development cycles.
