都是这套）已内置预设","3. 其它门户：看一下登录页表单的 `action` 和各 `input` 的 `name`。登录 URL 可填完整地址，也可只填以 `/` 开头的路径（自动拼到跳转地址的主机上）；字段名填 `用户名字段,密码字段`；隐藏域填到附加参数，如 `cmd=authenticate`","4. 点 **测试连接**：`ok` 表示门户登录和拉取都通了；`portal-login-fail` 看后面的原因，`portal: Authentication failed` 就是账号密码不对","","注意：","- 服务端 URL 必须是这个网络能访问到的地址：公司网里访问不到家里的 `192.168.1.x`，要用公网域名或内网穿透","- 门户通常只劫持 80/443，直连别的端口只会超时、HTTPS 只会证书错，所以主请求失败时固件会用 `http://connect.rom.miui.com/generate_204` 探测一次确认是否被拦截；正常轮询不多发请求","- 门户按 MAC 放行几小时到几天，到期设备会自动重新登录；连续 3 次登录失败把间隔拉到 15 分钟，避免锁号","- ESP8266 只有 2.4 GHz；不支持 WPA2-Enterprise（802.1X）和要跑

[dashboard-backend](https://github.com/jackwuwei/dashboard-backend) 的 git submodule，","与 Kindle 看板共用。本设备的数据走 `GET /api/eink.json`（`server/app/eink.py`），由 `config.yaml` 的 `eink:`

字库额外包含了全国地级市名（`preview/charset_city.txt`，只进 16px）。","","部署示例（服务端跑在 NAS `192.168.1.100` 上）：HTTP `http://192.168.1.100:8090`。本文里的地址都是示例，换成你自己的。","服务端只提供 HTTP，要 HTTPS 就在前面自己加一层反代。固件侧两种验证方式：内置根 CA（`ca_certs.h` 里是 ISRG Root X1，","即公网域名上的 Let's Encrypt 证书），或者填指纹——自签证书用这个：","`echo | openssl s_client -connect 192.168.1.100:8443 2\u003e/dev/null | openssl x509 -noout -fingerprint -sha1`。","切到 HTTPS：按住 SW3 复位进配网 → 服务端 URL 改成 `https://…` → 选证书验证方式 → 测试连接 → 保存。","","## 布局与字体","","- 布局以 `preview/mock.py`（PIL）为准：改坐标先在本地渲染确认，再同步到 `ui.cpp`（坐标一一对应）。`cd preview \u0026\u0026 uvx --with pillow python mock.py out.png`","- 预览图直接用固件里的 u8g2 点阵字库绘制（`preview/u8g2font.py` 从 `fonts_noto.c` 和 U8g2 的 `u8g2_fonts.c` 解码），","  所以和屏幕逐像素一致，文字宽度也一致。`u8g2_fonts.c` 默认到 `~/arduino-user/libraries/U8g2_for_Adafruit_GFX/src/` 找，","  路径不同就设环境变量 `U8G2_FONTS_C`。预览里某个字位置空白，说明字库里没这个字，按下面的步骤重新生成字库。","- 三个预览脚本都支持 `--en`，画英文界面（英文比中文宽，改文案后用它确认不串行）：`uvx --with pillow python preview/mock.py --en`","- 字体：Noto Sans CJK SC 转成 u8g2 位图，14 / 16 / 18 px（`fonts_noto.c`，字符集 `preview/charset.txt` 由 `preview/gen_charset.py` 从源码 + 服务端 weather.py/config.yaml 自动收集），","  时间用 u8g2 自带

ECDHE，现代服务器（公司门户、公网站点）一律回 handshake_failure（日志 `ssl 40`）。多占 ~60 KB flash，无所谓。","- **看 WiFi 连不上的真实原因**：编译加 `--build-property \"compiler.cpp.extra_flags=-DWIFI_SDK_DEBUG\"` 打开 SDK 状态机日志。`state: 2 -\u003e 3 (0)` 是认证过了，","  `state: 3 -\u003e 0 (12)` 是关联被 AP 拒绝，括号里是 802.11 状态码（十六进制）：0x12=18 基本速率集不满足（SSID 只收 11ax/双流客户端，ESP8266 无解）、","  0x1f=31 要求 802.11w、0x11=17 客户端数满。`reason=203` 只告诉你“关联失败”，看不出这些。","- **开放网络不能带密码**：ESP8266 core 的 `begin()` 只要密码非空就把 authmode 设成 WPA，开放的访客 WiFi 会被过滤掉，明明扫得到却报 reason 201 no-ap。","  固件连不上时会扫描一次，目标是开放网络就去掉密码重连并把空密码存回去；配网页选到开放网络也会清空密码。","- **按键 2 (GPIO0) 和屏幕 DC 引脚共用**：屏幕初始化后 GPIO0 是输出，直接 `digitalRead` 永远是高。`keys.cpp` 读按键时临时切回输入、读完恢复输出高（只在屏幕不传数据时读，同原固件）。","- **刷新序列必须和原固件一致**：`display.init(0,0,10,0)` + 一律局刷；用 `init(0,1)` 做真全刷后，同一次上电里的局刷不上屏。\"全刷\"改为整屏刷黑再刷白（原固件 `BW_refresh`）。","","- **ESP8266 ADC 在 RF 关闭的唤醒里读数偏高 0.3 V**（基准依赖射频校准）：电压只在 RF 打开的唤醒（联网轮询）采样，分钟唤醒沿用缓存；充电推断只用这些样本。","- **充电检测无硬件信号**（GPIO3 断电后是高阻+上拉，试过不行）：实测充电中 4.34–4.35 V、拔掉 4.28 V，阈值 ≥4.32 充电 / \u003c4.29 取消，未充满靠上升趋势。","","- **WiFi 连不上（关联后 reason 8 被踢）**：华硕 WiFi 6/7 路由器 + ESP8266 默认 802.11n 模式会这样；固件连接前强制 `WIFI_PHY_MODE_11G`。","  原固件能连是因为 SDK 把这个模式持久化在 flash 里，整块刷写后被清掉了。","- **U8g2 字库放在 DRAM**：原版库在 ESP8266 上没把字库放进 flash，链接直接超 RAM；对 `~/arduino-user/libraries/U8g2_for_Adafruit_GFX` 打了和仓库","  `U8g2_for_Adafruit_GFX20211226.7z` 同样的补丁（字库进 `.text.*` 段 +

<p dir="auto">4.2 寸 Z96 墨水屏 + ESP8266，硬件是 <a href="https://gitee.com/Lichengjiez/weather-ink-screen" rel="nofollow">Lichengjiez/weather-ink-screen</a> 的 4.2 寸板 revB-230621（HINK-E04A13-A0 / Z96 屏）。
本仓库是在这块板子上重写的独立固件：把屏做成家庭机房（NAS / 树莓派 / 路由器）状态看板，保留原固件的时间、温湿度、电量显示，并带万年历和天气预报页。
屏幕驱动、时钟芯片、温湿度、电压检测逻辑从原固件移植，不改硬件。设计文档见 <a href="/jackwuwei/eink-dashboard/blob/main/DESIGN.md">DESIGN.md</a>，可 3D 打印的外壳在 <code>stl/</code>（见<a href="#%E6%96%87%E4%BB%B6">文件</a>）。</p>

<p dir="auto">从左到右、从上到下：看板、Claude 用量、服务器详情、天气、万年历、设备信息。</p>
<p dir="auto">顶栏（时钟 / SHT30 温湿度 / 当前天气小图标 / WiFi / 电量）由设备本地数据每分钟局刷；内容区来自服务端 JSON，有变化才局刷。
（图为 <code>preview/</code> 脚本渲染的布局预览，与固件坐标一一对应）</p>
<ul dir="auto">
<li><strong>页面</strong>（交互窗口内 SW2 / SW3 翻页）：看板 → Claude 用量 → 服务器详情 → 天气 → 万年历 → 设备信息
<ul dir="auto">
<li>万年历：农历、二十四节气、节日全部在设备端查表（2019–2100，与 lunar_python 逐日对拍无差异），不依赖网络</li>
<li>天气：当前天气 + 4 天预报 + 日出日落 + 提示语，图标沿用原固件位图；数据由服务端下发，默认 Open-Meteo（免 key）并按公网 IP 自动定位，也可手动指定城市或改用心知天气</li>
</ul>
</li>
<li><strong>数据来源</strong>：<code>server/</code> 里的共用服务端——git submodule 指向 <a href="https://github.com/jackwuwei/dashboard-backend">dashboard-backend</a>，
和 Kindle 看板同一套（NAS 上的 Docker），提供 <code>GET /api/eink.json</code>，
支持 HTTP / HTTPS（BearSSL，内置根 CA 或指纹校验）、上游 WiFi 门户自动登录</li>
<li><strong>省电</strong>：整分对齐深睡；每分钟只刷顶栏；每 N 分钟（默认 5，夜间 30）联网一次；每小时整点清一次残影；660 mAh 电池</li>
<li><strong>配网</strong>：按住 SW3 复位进入热点 <code>ESP8266 E-Paper</code>，手机连上自动弹配置页（Captive Portal）</li>
<li><strong>不改硬件</strong>：屏幕驱动、时钟芯片、温湿度、电压检测逻辑均从原固件移植；原天气固件的整块 flash 备份在 <code>backup/</code>，可随时刷回</li>

逐日对拍 0 差异）。不依赖网络。</li>
<li><strong>天气</strong>：由服务端随 <code>/api/eink.json</code> 的 <code>w</code> 字段下发（<code>server/app/weather.py</code>），设备按心知天气码选图标（图标沿用原天气固件的
45×45 位图 <code>weather_icons.h</code>）。默认 <strong>Open-Meteo（免 key）+ 按服务端公网 IP 自动定位</strong>（<code>myip.ipip.net</code> 取城市 → Open-Meteo

<p dir="auto">部署示例（服务端跑在 NAS <code>192.168.1.100</code> 上）：HTTP <code>http://192.168.1.100:8090</code>。本文里的地址都是示例，换成你自己的。
服务端只提供 HTTP，要 HTTPS 就在前面自己加一层反代。固件侧两种验证方式：内置根 CA（<code>ca_certs.h</code> 里是 ISRG Root X1，
即公网域名上的 Let's Encrypt 证书），或者填指纹——自签证书用这个：
<code>echo | openssl s_client -connect 192.168.1.100:8443 2&gt;/dev/null | openssl x509 -noout -fingerprint -sha1</code>。
切到 HTTPS：按住 SW3 复位进配网 → 服务端 URL 改成 <code>https://…</code> → 选证书验证方式 → 测试连接 → 保存。</p>
