Raspberry Pi I2C Sensor Development / 树莓派 I2C 传感器开发

What problem does it solve?

This skill eliminates the common, time-consuming headaches of Raspberry Pi I2C sensor development, including incorrect GPIO wiring, unreliable software I2C bit-banging, BMI270 configuration loading failures, and undetected I2C devices that stall embedded projects.

Core Features & Use Cases

• Verified hardware guidance: Includes multi-source checked GPIO pinout tables, electrical safety rules, and clear standard vs software I2C selection criteria to avoid hardware damage and pin conflicts.
• Production-ready sensor drivers: Provides tested, optimized driver implementations for the BMI270 6-axis IMU and MAX30205 temperature sensor, with both Python (gpiod bit-banging) and C (libgpiod / ioctl) code examples.
• Comprehensive troubleshooting playbook: Covers step-by-step fixes for common failures like I2C device scan errors, BMI270 initialization timeouts, gpiod permission issues, and Flask web interface errors. Use case: For example, if you need to connect a BMI270 to non-standard GPIO8/9 pins while also running a MAX30205 on the default I2C-1 bus, this skill gives you the exact wiring, driver code, and configuration steps to get both sensors working reliably.

Quick Start

Use the Raspberry Pi I2C Sensor Development skill to wire your BMI270 and MAX30205 sensors, load the correct drivers for your chosen I2C bus type, and troubleshoot any communication issues you encounter during setup.
