Wi-Fi 配置在 `menuconfig -> Example WIFI Configuration` 中配置 Wi-Fi SSID `WiFi STA SSID` 和密码 `WiFi STA Password`。 2. 测试功能配置在 `menuconfig -> Audio Test Solution Configuration` 中配置 AFE 功能。注意：当开启唤醒词和命令词识别时，需要至少 8MB Flash，并使用 `partitions_sr_model.csv` 分区表。 - 默认开启 AEC：`Enable AEC` - 默认关闭唤醒词识别：`Enable Wakeup` - 默认关闭语音命令识别：`Enable Voice Command` 在开启 AFE 功能后，需进一步根据硬件设计配置 AFE 相关配置 `ESP GMF Loader -> GMF Audio Configurations -> GMF AI Audio -> Initialize GMF AI Audio AFE -> Audio Front-End (AFE) Configuration` - `Feed Task Setting` 和 `Fetch Task Setting`：任务相关设置 - `AFE Channel Allocation`：根据硬件设计配置麦克风通道信息，使用 `M`、`R`、`N` 字符分别表示麦克风、回采信号和未使用通道默认开启 `Enable store test audio in embed flash` 选项，将必要的待播放音频嵌入固件中，以减少对网络带宽的依赖。 3. 分区配置在 `menuconfig -> Partition Table` 中配置分区表。 - 默认使用 `partitions.csv` 分区表 - 当开启唤醒词和命令词识别时，需要使用 `partitions_sr_model.csv` 分区表，或根据 log 信息自定义分区表大小 ### 编译和下载编译本例程前需要确保已配置 ESP-IDF 的环境。如果已配置可跳到下一项配置；如果未配置，需要先在 ESP-IDF 根目录运行下面脚本设置编译环境。有关配置和使用 ESP-IDF 的完整步骤，请参阅 [《ESP-IDF 编程指南》](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32s3/index.html)： ```bash ./install.sh . ./export.sh ``` - 执行预编译脚本，根据提示选择编译芯片，自动设置 IDF Action 扩展，通过 `esp_board_manager` 选择支持的开发板或自定义开发板在 Linux / macOS 中运行以下命令： ```bash source prebuild.sh ``` 在 Windows 中运行以下命令： ```powershell .\prebuild.ps1 ``` - 通过 `esp_board_manager` 选择支持的开发板或自定义开发板，请务必参阅 [ESP Board Manager](https://components.espressif.com/components/espressif/esp_board_manager)，以 ESP32-S3-Korvo2 V3.1 为例： ```bash idf.py gen-bmgr-config -b esp32_s3_korvo2_v3 ``` - 使用 menuconfig 配置工程，参考[配置](#配置)章节修改配置项 ```bash idf.py menuconfig ``` - 编译例子程序 ```bash idf.py build ``` - 烧录程序并运行 monitor 工具来查看串口输出 (替换 PORT 为端口名称)： ```bash idf.py -p PORT flash monitor ``` - 退出调试界面使用 `Ctrl-]` ## 如何使用例程 ### 功能和用法 - 例程开始运行后，将自动连接到 Wi-Fi 并启动 WebSocket 服务，等待电脑连接 ```plaintext I (1059) main_task: Calling app_main() I (1062) MAIN: [1/4] Initializing board...
