功能：添加 Wi-Fi 连接管理组件

Browse Source 
在 wifi-connect.c 中实现了新的 Wi-Fi 连接管理模块，负责配网、连接及状态上报。

添加了用于 Wi-Fi 配置和状态显示的 HTML 界面。

集成了 NVS 用于存储 Wi-Fi 凭证。

更新了 CMakeLists.txt 以包含新模块的依赖项。

修改了 main.c 以初始化 Wi-Fi 连接管理并等待连接成功。

# 组件：BH1750
[![组件注册](https://components.espressif.com/components/espressif/bh1750/badge.svg)](https://components.espressif.com/components/espressif/bh1750)
![维护状态](https://img.shields.io/badge/maintenance-as--is-yellow.svg)
:warning: **BH1750 组件按“现状”提供，不再进行后续开发及兼容性维护**
* 本组件将向您展示如何使用 I2C 模块读取外部 I2C 传感器数据，此处以 BH1750 光传感器（GY-30 模块）为例。
* BH1750 测量模式：
* 单次模式：BH1750 仅在接收到单次测量命令时测量一次，因此每次需要获取光照强度值时，都需要发送该命令。
* 连续模式：BH1750 在接收到连续测量命令后将持续进行测量，只需发送一次该命令，之后反复调用 `bh1750_get_data()` 即可获取光照强度值。
## 注意：
* BH1750 在不同测量模式下的测量时间不同。可通过调用 `bh1750_change_measure_time()` 更改测量时间。

# wifi-connect 组件说明
`wifi-connect` 是一个基于 ESP-IDF 的 Wi-Fi 配网组件，支持：
- 长按按键进入配网模式
- 启动 SoftAP + Captive Portal（网页配网）
- 手机连接热点后，通过网页扫描并选择路由器
- 保存 Wi-Fi 凭据到 NVS
- 下次开机自动重连
- 支持两种配网模式：按键触发 / 常驻配网
面向最终用户的一页版操作说明见：`USER_GUIDE.md`
现场打印张贴版（四步卡）见：`QUICK_POSTER.md`
---
## 目录结构
- `wifi-connect.c`：组件主实现（按键、APSTA、HTTP、DNS、状态机）
- `include/wifi-connect.h`：对外 API
- `Kconfig.projbuild`：组件配置项
- `CMakeLists.txt`：组件构建依赖
---
## 对外 API
头文件：`include/wifi-connect.h`
- `esp_err_t wifi_connect_init(void);`
- 初始化组件（NVS、Wi-Fi、事件、按键任务等）
- 尝试自动连接已保存网络
- `esp_err_t wifi_connect_start(void);`
- 启动配网（APSTA + HTTP + DNS）
- `esp_err_t wifi_connect_stop(void);`
- 停止配网（关闭热点与相关服务）
- `wifi_connect_status_t wifi_connect_get_status(void);`
- 获取当前状态：`idle / provisioning / connecting / connected / failed / timeout`
- `esp_err_t wifi_connect_get_config(wifi_connect_config_t *config);`
- 读取已保存的 Wi-Fi 凭据
- `esp_err_t wifi_connect_clear_config(void);`
- 清除已保存的 Wi-Fi 凭据（SSID/密码）
---
## 快速使用
在 `main/main.c`：
```c
#include "esp_check.h"
#include "wifi-connect.h"
void app_main(void)
{
ESP_ERROR_CHECK(wifi_connect_init());
}
```
运行后：
1. 选择配网模式：
- 按键触发模式：长按配置按键进入配网
- 常驻配网模式：上电自动进入配网
2. 手机连接 `ESP32-xxxxxx` 热点
3. 打开 `http://192.168.4.1`
4. 选择 Wi-Fi 并输入密码提交
5. 配网行为：
- 按键触发模式：连接成功后按配置自动关闭热点
- 常驻配网模式：配网热点保持开启，不自动关闭
如需清空历史凭据，可在配网页面点击“清除已保存”。
---
## Kconfig 配置项
在 `idf.py menuconfig` 中：`WiFi Connect` 菜单
- `Provisioning mode`：配网模式（二选一）
- `Button triggered`：按键触发配网（默认）
- `Always-on provisioning`：常驻配网（上电自动进入且不自动关闭）
- `WIFI_CONNECT_BUTTON_GPIO`：进入配网的按键 GPIO
- `WIFI_CONNECT_BUTTON_ACTIVE_LEVEL`：按键有效电平
- `WIFI_CONNECT_DEBOUNCE_MS`：按键去抖时间
- `WIFI_CONNECT_LONG_PRESS_MS`：长按触发时长
- `WIFI_CONNECT_BUTTON_STARTUP_GUARD_MS`：上电保护窗口（该时间内忽略长按检测）
- `WIFI_CONNECT_BUTTON_RELEASE_ARM_MS`：松手解锁时间（先稳定松手再允许长按触发）
- `WIFI_CONNECT_CONNECT_TIMEOUT_SEC`：连接路由器超时
- `WIFI_CONNECT_IDLE_TIMEOUT_SEC`：配网页面空闲超时
- `WIFI_CONNECT_MAX_SCAN_RESULTS`：扫描网络最大数量
- `WIFI_CONNECT_AP_MAX_CONNECTIONS`：SoftAP 最大连接数
- `WIFI_CONNECT_AP_GRACEFUL_STOP_SEC`：联网成功后 AP 延迟关闭秒数
---
## 日志与状态说明（中文）
组件会输出统一中文状态日志，例如：
- `【状态】wifi-connect 初始化完成`
- `【状态】检测到按键长按：开始进入配网模式`
- `【状态】配网已启动：配网热点已开启，SSID=...`
- `【状态】开始连接路由器：收到配网请求，目标网络=...`
- `【状态】联网成功：已连接 ...，获取 IP=...`
- `【状态】配网已停止：热点已关闭，设备继续以 STA 模式运行`
说明：ESP-IDF 驱动层（如 `wifi:`、`esp_netif_lwip:`）仍会输出英文日志，这是框架默认行为。
---
## 常见问题
### 1) 手机连上热点但不自动弹出页面
- 手动访问：`http://192.168.4.1`
- 确认手机没有强制使用 HTTPS
- 查看串口是否有 `配网已启动`、`DNS 劫持服务已启动` 日志
### 2) 提交后连接失败
- 检查密码是否正确
- 查看日志中的失败原因码（`连接失败，原因=...`）
- 检查路由器是否禁用了新设备接入
- 若曾保存过旧配置，可先在页面点击“清除已保存”后再重试
### 4) 按键未按下却误触发配网
- 常见原因是按键引脚与 LCD/外设复用，初始化期间电平抖动被误判为长按
- 可增大 `WIFI_CONNECT_BUTTON_STARTUP_GUARD_MS`（如 8000~10000）
- 可增大 `WIFI_CONNECT_BUTTON_RELEASE_ARM_MS`（如 300~500）
- 若硬件允许，优先给配网按键使用独立 GPIO
### 5) 成功后热点消失是否正常
- 在按键触发模式下：正常，可通过 `WIFI_CONNECT_AP_GRACEFUL_STOP_SEC` 调整关闭延时
- 在常驻配网模式下：热点不会自动关闭
---
## 依赖
由 `CMakeLists.txt` 声明：
- `esp_wifi`
- `esp_timer`
- `esp_event`
- `esp_netif`
- `nvs_flash`
- `esp_http_server`
- `lwip`
- `driver`
---
## 版本建议
- 推荐 ESP-IDF `v5.5.x`
- 当前项目验证环境：`esp-idf v5.5.2`（ESP32-C3）
