两块 ESP32-S3-WROOM-1-N16R8 图传板(DVP 接口接 OV2640/OV3660/OV5640), 向队伍客户端与裁判终端推 UDP 图传。固件是跑在 ESP-IDF 上的 Rust,用官方 esp32-camera 组件采集;客户端是 Rust + Slint 桌面程序。 三个 crate 各自独立构建: . firmware,交叉编译到 Xtensa protocol/ 线路格式与帧重组,两端共用,无 ESP-IDF 依赖,有单元测试 client/ Slint 桌面客户端 视频走 UDP 而非 TCP:实测传感器产出 22 fps,TCP MJPEG 只送出 1.9 fps, 且只占用链路能力的 1%——链路是空的,帧堵在队头阻塞后面等一个实时画面 等不起的重传计时器。改为独立数据报、不重传、缺片丢整帧后达到 20.8 fps。 发现是双向的:板子每 2 秒广播 Hello,客户端广播 Subscribe,板子据此定向 推流。板子身份由 MAC 派生,重启不变,所以客户端可以把绑定存进配置。 裁判端同时收两块板子(每个发送方一个重组器),队伍端绑定其中一块并只显示 自己那一边的血量。装甲板接口已预留(ArmorSource trait + ARMOR_PORT), 当前无数据源,界面显示占位符。 vendor 了 esp32-camera 2.1.7:组件注册表的版本求解器找不到它,且需要打一处 补丁(见 components/esp32-camera/target/esp32s3/ll_cam.c)。 .gitignore 三条 target/ 都锚定在根目录,因为 protocol/ 与 client/ 各自也是 独立 crate;而 components/esp32-camera/target/ 是上游的按芯片分目录,里面是 源码,必须保留。
