/**

|
|
* transport.js — 电机控制台的传输选择层
|
|||
|
|
*
|
|||
|
|
* 电机页支持两条链路，业务逻辑（解码、节点列表、STATUS 面板、波形、命令序列、
|
|||
|
|
* 流控）**完全共用**，只有"数据怎么进出"这一层不同：
|
|||
|
|
*
|
|||
|
|
* wifi ESP32 固件 80 端口的 HTTP API（原有实现，行为未变）
|
|||
|
|
* ecat EtherCAT 过程数据，经本地页面服务器 /ecat/api/* 代理到
|
|||
|
|
* tools/ecat/src/ecat_server.py
|
|||
|
|
*
|
|||
|
|
* 传输实例必须实现的接口（详见两个实现文件的注释）：
|
|||
|
|
* id / label / supportsOta / supportsPeriodSync
|
|||
|
|
* sendHint(ch) -> string
|
|||
|
|
* probe() -> statusData 连接探测，抛错=没连上
|
|||
|
|
* fetchStatus(wantFull) -> statusData 健康检查
|
|||
|
|
* describeStatus(data) -> string[] #devStatus 文本片段
|
|||
|
|
* reportedIp(data) -> string|null 设备回报 IP（ECAT 恒 null）
|
|||
|
|
* fetchMotorState() -> {have_data, age_ms, active_count, boot_active, motors[]}
|
|||
|
|
* fetchFeedback() -> {channels:[{ch,enabled,valid,rx,tx,err,tec,rec,bus_state}]}
|
|||
|
|
* sendFrames(frames, {ch}) -> results[] frames=[{id,dlc,data}]
|
|||
|
|
* sendBurst(frames, {suffix,dlc}) -> results[]
|
|||
|
|
* fetchVersionNode(node) -> {node,seq,version}|null
|
|||
|
|
* setPeriod(ms) -> void 不支持则空实现
|
|||
|
|
* teardown() -> void 切走时收尾
|
|||
|
|
* 可选：takeNodeIdReport(node)、debug()
|
|||
|
|
*
|
|||
|
|
* motors[] 每项的字段契约（ECAT 实现负责补平差异）：
|
|||
|
|
* {node, ch, online, dlc, rx_count, seq, data(64hex), config_data(48hex|"")}
