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>
