对我的电动滑板车进行逆向工程并使用 Rust 重写固件
Reverse engineering my e-scooter and rewriting the firmware in Rust

此数据日志包含一系列 CAN 总线通信帧。日志反映了一个重复的循环，其中包含标准操作信号（ID 1024、1025、1028、513、515 和 528），以及通过 ID 495 传输的诊断或识别数据，该 ID 输出字符串（例如 "L.D.CR.S807.C.2.1" 和 "EG.2.2.1"）。 主要观察结果包括： * **循环流量：** ID 1024、1025 和 1028 显示出连续的心跳式消息。 * **初始化/握手：** 帧 494 和 495 似乎用于辅助握手或版本信息交换。 * **系统状态：** ID 768 有周期性的更新记录（[0, 90, 100, 90, 100...]）。 * **扩展帧：** 在初始化序列之后，日志以引入包含特定负载数据的扩展 ID（1856、1857、1861）结束。 总体而言，该日志呈现了一个典型的汽车或工业控制网络过程，涉及设备发现、状态报告和持续的周期性通信。
