--- name: Developing IoT Applications with MicroPython version: "1.0" category: Python Cursor Rules description: Best practices for writing Python code for IoT devices using MicroPython, focusing on efficiency and hardware interaction. --- ## Coding Standards - **Use MicroPython-Specific Libraries**: Utilize MicroPython's built-in libraries such as `machine` and `network` for hardware control and network operations. - **Optimize for Resource Constraints**: Be mindful of the limited memory and processing power of IoT devices. Avoid unnecessary memory allocations and choose efficient algorithms. ## Style Guidelines - **Follow PEP 8**: Adhere to Python's PEP 8 style guide for code readability and consistency. - **Use Descriptive Naming**: Choose clear and descriptive names for variables, functions, and modules to enhance code maintainability. ## Best Practices - **Modularize Code**: Break down code into reusable modules and functions to improve readability and facilitate testing. - **Implement Error Handling**: Use `try-except` blocks to handle potential errors gracefully, ensuring the application can recover from unexpected issues. - **Utilize Asynchronous Programming**: Employ MicroPython's `uasyncio` library for non-blocking I/O operations, allowing the device to handle multiple tasks concurrently. - **Optimize Power Consumption**: Implement power-saving techniques such as deep sleep modes and turning off unused peripherals to extend battery life. ## Testing - **Write Unit Tests**: Develop unit tests for individual components to ensure functionality and facilitate debugging. - **Perform Integration Testing**: Test the interaction between different modules to verify that the system operates as intended. ## Documentation - **Use Docstrings**: Provide clear docstrings for all functions and modules to explain their purpose and usage. - **Maintain Updated Documentation**: Keep project documentation current with setup instructions, usage guidelines, and contribution protocols.
