原理图/PCB 已在 EasyEDA 里做到 12 页跨页 0 漏接，固件刚完成骨架包 A1。 这次是把已有的一切一次性纳入版本控制，没有改动任何设计内容。 纳入： - 设计与需求文档、PROGRESS.md、小米8 参考原理图 PDF 与追脚脚本 - .claude/ 下的 EasyEDA 桥接工具链与几何/网表缓存（eda-parts.json、 pcb-parts.json、pcb-pads.json、p2-ch1.json 等，是重画各页的唯一事实来源） - 117 张验证截图（本项目所有方向问题都是靠人眼看截图发现的，属于证据不是垃圾） - firmware/ 的 A1 骨架与 site/ 文档站源码 .gitignore 排除：构建产物（firmware/build、host/build、sdkconfig）、 site/node_modules、__pycache__、桥接日志 _bridge.log、脚本自标的 *.stale。 .gitattributes 默认 `* -text`：现有 .py/.json 大多是 CRLF，原样存， 不让 git 重写行尾。唯一例外是 *.sh 强制 LF —— 带 \r 的 shell 脚本 bash 跑不了。 Co-Authored-By: Claude Opus 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01QYuExfgyYa6DzRRcUso8M8

u"""补上 §25.8 遗留的**悬空 GND 焊盘** —— 自己找出来，自己打孔。
|
||||
|
||||
/c/Python314/python .claude/pcb2_route_dp.py --dump # 1. 先刷障碍表
|
||||
/c/Python314/python .claude/pcb2_gnd_patch.py # 2. 找悬空 + 选孔位 + 净距校核
|
||||
/c/Python314/python .claude/pcb2_gnd_patch.py --check # 只问「现在板上还有没有悬空的」
|
||||
/c/Python314/python .claude/pcb2_gnd_patch.py --push # 3. 下发（**只加不删**）
|
||||
/c/Python314/python .claude/pcb2_pour.py --push # 4. 必须重铺
|
||||
|
||||
## 「悬空」是自己算的，不是抄 DRC
|
||||
|
||||
把 GND 网络的**焊盘 / 过孔 / 导线**当图，两两相触连边（判据同 `pcb2_net_conn.py`），
|
||||
一个连通域里只要有**一个过孔或一个通孔焊盘**，它就落到 Inner1/Inner2 的地平面上 = 连通。
|
||||
**一个都没有的连通域就是悬空的** —— 那是纯顶层/底层的一小块孤铜。
|
||||
|
||||
⇒ 这个判据是幂等的：补完孔再跑一次，找到 0 个。
|
||||
|
||||
## 和 `pcb2_fanout.py` 的分工
|
||||
|
||||
`pcb_fanout` 是**批量**扇出（210 个孔），它对每个焊盘只试固定的几个方位，
|
||||
挤不下就跳过 —— §25.8 里剩下的这几个就是被它跳过的。
|
||||
这里换成和 `pcb2_vo_vias.py` 同一套搜索：8 个方向 × 距离 × 线宽阶梯，逐个试到过为止。
|
||||
|
||||
## 下发**不能**用 `pcb2_route_dp.push()`
|
||||
|
||||
那个函数会先把 net 上**所有**线和过孔删掉再重画 —— 对 GND 就是把 210 个扇出孔
|
||||
连同 BM24 的两条梳子全部抹掉。这里自己写一段只动**本脚本自己那几个对象**的 JS。
|
||||
|
||||
## ⚠️ 幂等靠 `_pcb2_gnd_patch.json` 这份「我上次画了啥」的清单
|
||||
|
||||
GND 上有两百多个别人的过孔，没法按网络整网重画，所以本脚本把自己下发的
|
||||
过孔/导线坐标记在 `_pcb2_gnd_patch.json` 里，下次 `--push` 先按坐标删掉它们再重画。
|
||||
|
||||
**不记账的代价实测过一次**：改完选点逻辑直接再 `--push`，板上就多出一对
|
||||
旧坐标的过孔（425 而不是 423），而且新画的短线被 EasyEDA 并进了旧的粗线里 ——
|
||||
DRC 照样报错，看上去像"改了没生效"。
