ESP32-S3 吊坠设备固件，集成火山引擎 RTC 语音助手、蓝牙配网、 VEML7700 环境光传感器驱动及石头同频匹配交友功能。 VEML7700 驱动： - 基于 ESP-IDF i2c_master API 实现，复用项目 I2cDevice 基类 - 支持 ALS + White 双通道、自动量程、Vishay 非线性校正 - 3 次采样取中位数过滤偶发异常 石头同频匹配算法（双维度）： - 维度1：光谱比值 ALS/White（石头固有光学特征，不随光照强度变化） - 维度2：亮度等级（5级对数划分，排除极端环境差异） - 比值阈值 15%，实测同石头姿势变化波动 1.6%~9.6%，安全余量充足 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
