阶段1: 将 dzbj 项目的 LVGL 8.3.11 LCD 显示集成到 AI小智 主项目， 开机显示 ScreenHome 界面，同时优化配网模式下的内存使用， 确保 WiFi+BLE+LVGL 三者共存运行。 ## 新增功能 ### dzbj 显示模块集成 - 新增 main/dzbj/ 目录，移植 LCD 驱动(ST77916 QSPI)、触摸驱动(CST816S)、 LVGL 初始化和 SquareLine Studio UI 界面 - I2C 总线共享：dzbj 触摸控制器复用主项目的 I2C_NUM_1 总线 - GPIO 冲突解决：LED(GPIO21)、Touch1(GPIO1)、Touch4(GPIO7) 改为 NC， 电池 ADC 从 GPIO6 改为 GPIO3 - 添加 LVGL、esp_lcd_st77916、esp_lcd_touch_cst816s 等组件依赖 - managed_components 纳入版本管理 ### 配网模式轻量化启动 - BoxAudioCodec: 新增 output_only 模式，仅创建 I2S TX 通道（省 ~13KB DMA） 跳过 ES7210 ADC 初始化（省 ~2-4KB） - AudioCodec: 新增 StartOutputOnly() 方法，仅启用扬声器输出 - Application: 配网模式跳过 Opus 编码器、输入重采样器、协议初始化、 天气位置检测等网络业务 - 板级构造函数: 配网模式跳过电池检测、IMU传感器、PowerSaveTimer ### WifiBoard 配网流程修复 - NeedsProvisioning() 静态方法: 读取 NVS force_ap 和 SSID 列表， 用于提前判断配网模式 - force_ap 竞态修复: 构造函数不再清零 force_ap，改在 StartNetwork() 清零， 确保 NeedsProvisioning() 能正确读到 force_ap=1 - Application 缓存 provisioning_mode_ 成员变量，避免重复读 NVS ### BLE 配网重启修复 - 配网成功后用 esp_timer 延迟重启替代 xTaskCreate， 避免内存紧张时任务创建失败导致设备不重启 - 注释掉 WiFi 连接成功后的 MAC 地址发送步骤 ### sdkconfig 内存优化 - BT_ALLOCATION_FROM_SPIRAM_FIRST=y (BLE 动态分配优先 PSRAM) - SPIRAM_MALLOC_RESERVE_INTERNAL=32768 - NVS_ALLOCATE_CACHE_IN_SPIRAM=y - WiFi 静态缓冲区数量优化 (RX=10, TX=8) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
