Build successful! Let me note the memory usage:
- RAM: 14.9% (48,708 / 327,680 bytes) - was 14.4% before, added about 1.6KB for the display framebuffer and button state
- Flash: 43.5% (1,453,861 / 3,342,336 bytes) - was 27.5% before, added about 534KB mainly from U8g2 library with Chinese fonts

That's a significant flash increase from the Chinese fonts, but well within the 8MB limit. The RAM increase is minimal thanks to PSRAM.

Let me also update the wm_strings_en.h file to make sure it's still the Chinese version (may have been overwritten by library reinstall).

短接了配网按钮行吗


The user is asking if shorting (short-circuiting) the provision button is OK. They're asking about the wiring - whether connecting GPIO14 directly to GND (shorting) for the button is acceptable.

With INPUT_PULLUP, the button is connected between GPIO and GND. When pressed, it shorts GPIO to GND, which is perfectly safe because:
1. INPUT_PULLUP enables an internal ~45kΩ pull-up resistor
2. When the button shorts GPIO to GND, current flows through the internal pull-up (~3.3V/45kΩ ≈ 73µA) - very safe
3. This is the standard way to wire buttons with Arduino/ESP32

The user might also be asking if they can temporarily short the pin to test - also fine.

Let me give a clear, reassuring answer.


没问题。`INPUT_PULLUP` 模式下，GPIO14 内部有一个约 45kΩ 的上拉电阻，短接到 GND 时电流只有约 73µA，完全安全。

接线方式：

```
GPIO14 ────┬──── 按钮 ──── GND
            │
    (内部 ~45kΩ 上拉到 3.3V)
```

- **没按**：GPIO14 读到 HIGH（3.3V）
- **按下**：GPIO14 读到 LOW（0V），电流 ~0.07mA，安全

这就是最常见的按钮接法，直接飞线短接测试也完全不会烧板子。


短接了后便没有重新配网，也没有之前的单片机wifi


The user is saying that after shorting the provision button (GPIO14 to GND for 3 seconds), the device didn't enter provisioning mode, and the ESP32's WiFi AP ("HealthMonitor-Setup") didn't appear.

Let me think about why:

1. The button manager has a 3-second long press threshold (`BTN_LONG_PRESS_MS 3000`). The user needs to hold the button for at least 3 seconds, then release.

2. But wait - looking at my button_manager.cpp code more carefully, there might be an issue. The `_processButton` function checks for long press on release. But what if the user just shorted the pins once (brief contact) and expected it to work? Or what if they held it and released, but the callback didn't fire?

3. Let me also check: the button callbacks are registered BEFORE `g_wifi.begin()`. But `g_wifi.startConfigPortal()` should work at any time.

4. Actually, wait - the button is on GPIO14. Let me check if there could be a conflict. GPIO14 is generally safe on ESP32-S3.

5. But actually, the more critical issue: the user didn't upload the new firmware yet! We compiled successfully but didn't upload to the device. The user probably just tested with the old firmware that doesn't have button support.

Let me check - the user said "短接了后便没有重新配网" - they shorted it but it didn't re-enter provisioning. And "也没有之前的单片机wifi" - the ESP32's WiFi AP didn't appear.

This could be:
1. The new firmware wasn't uploaded yet
2. The old firmware still uses GPIO0 for the provisioning button (not GPIO14)
3. GPIO0 still works for the old button

The old code (`wifi_manager.cpp`) handles GPIO0 for long press. The new button manager handles GPIO14/15/16. If we didn't upload the new firmware, GPIO14 won't do anything.

Let me tell the user: you need to upload the new firmware first, or use GPIO0 (the original button) for provisioning.

Also wait - the user said "有没有之前的单片机wifi" meaning the ESP32's AP didn't appear at all. This could also mean that:
- The ESP32 successfully connected to a previous WiFi network and didn't need to start the AP
- The device needs to be in a state where WiFi connection fails for the AP to appear
- Or the user didn't clear the previous WiFi config

Actually, looking at the wifi_manager code, after the initial setup, if WiFi connects successfully, the config portal won't start automatically on subsequent boots. The AP only appears when:
1. First boot (no saved WiFi config)
2. WiFi connection fails
3. Manual trigger via `startConfigPortal()`

For the old firmware (without the new button code), pressing GPIO14 won't do anything because only GPIO0 is monitored for long press.

Let me tell the user:
1. Upload the new firmware first
2. The new firmware supports GPIO14 long-press for provisioning
3. Or use GPIO0 (the original button) if using old firmware
4. To force provisioning, you can also clear the WiFi config and reboot


新固件还没上传，旧代码里配网按钮是 GPIO0，不是 GPIO14。

两个办法：

**直接用 GPIO0（旧固件也能用）：**
```
GPIO0 ──── 按钮 ──── GND  （长按 3 秒 → 配网）
```

**或者先上传新固件，GPIO14 就生效了：**
```
pio run --target upload
```

新固件三个按钮：

| 按钮 | 旧固件 | 新固件 |
|---|---|---|
| GPIO0 | ✅ 长按配网 | ✅ 长按配网（保留） |
| GPIO14 | ❌ 无反应 | ✅ 长按配网 |
| GPIO15 | ❌ | ✅ 短按解除报警 |
| GPIO16 | ❌ | ✅ 短按翻页 |

要我帮你上传新固件吗？


链接后无法擦除


The user is saying that after connecting something (likely the OLED or buttons), they can't flash/erase the ESP32-S3. This is likely a GPIO conflict issue.

Common causes on ESP32-S3:
- GPIO 14, 15, 16 are fine for buttons (they're not strapping pins)
- But wait - GPIO 21 (SDA) and GPIO 22 (SCL) are the OLED pins. Are these safe?

Actually, the issue might be simpler. When the user connected the OLED and buttons, maybe:
1. Something is shorted on the breadboard
2. The OLED/buttons are pulling some pins low/high that interfere with boot mode

ESP32-S3 strapping pins that affect boot/download:
- GPIO 0 (already used as button) - LOW at boot = download mode
- GPIO 46 - determines boot voltage
- GPIO 3, 45, 46 - other strapping pins

But GPIO 14, 15, 16, 21, 22 should all be safe. However, if the user shorted something wrong or has a loose connection, it could prevent flashing.

Let me think... The user said "链接后无法擦除" - after connecting (the OLED/buttons), they can't erase/flash.

Possible issues:
1. GPIO 0 is being used for the config button. If the user is holding it LOW or it's shorted, the ESP32 will be stuck in download mode or not boot properly.
2. If GPIO 3 is being used or touched, it could interfere with JTAG/USB
3. The OLED SDA/SCL on GPIO 21/22 might interfere if the OLED is powered but the ESP32 isn't properly initialized

Actually, the most likely cause: when the user added the new components on the breadboard, they might have accidentally disturbed existing connections, especially the GPIO 0 button which controls boot/download mode.

Let me suggest they:
1. Disconnect all new components (OLED + 3 buttons)
2. Try flashing again
3. If it works, add components one at a time

Or maybe the issue is that the ESP32-S3 uses native USB, and sometimes needs manual entry to download mode. Let me suggest pressing the BOOT button (GPIO 0 to GND) while resetting.

Actually, let me just give practical troubleshooting advice.


这是硬件接线干扰了烧录。试试以下步骤：

**先断开新加的模块，单独烧录：**

```
1. 拔掉 OLED + 三个按钮的所有杜邦线
2. 只保留 ESP32-S3 连接电脑
3. 重新上传：
   pio run --target upload
```

**如果还是不能擦除，手动进下载模式：**

```
按住 GPIO0 接 GND → 按一下 EN/RST → 松开 GPIO0
然后立即执行上传
```

**能烧进去之后，逐个接回去测试：**

| 顺序 | 接上 | 接好后测试 |
|---|---|---|
| 1 | OLED (VCC/GND/SCL/SCA) | 重新上电，看 OLED 有没有"启动中" |
| 2 | BTN3 翻页 (GPIO16) | 短按看能不能翻页 |
| 3 | BTN2 解除 (GPIO15) | 短按测试 |
| 4 | BTN1 配网 (GPIO14) | 长按能否进配网 |

常见坑：**GPIO0 已经用作配网按钮了**，如果你是按着 GPIO0 上电的，ESP32 会一直卡在下载模式不启动。检查一下 GPIO0 是不是被什么东西压住或者短路了。


esp32在用wifi时，还能用蓝牙吗


The user is asking whether ESP32 can use Bluetooth while WiFi is active. This is a general technical question about ESP32 capabilities - they might be considering adding BLE functionality for provisioning or data transmission.

The answer is yes, ESP32 supports WiFi and Bluetooth coexistence. They share the same 2.4GHz radio but use time-division multiplexing. But there are some caveats.

Since the project already uses ESP32-S3, which has better coexistence support than the original ESP32.

Let me give a clear answer.


可以的。ESP32 的 WiFi 和蓝牙共用 2.4GHz 天线，通过时分复用（共存机制）同时工作。

**但实际上有限制：**

| | ESP32 | ESP32-S3（你这块板） |
|---|---|---|
| 共存支持 | 协议栈级切换，常有冲突 | 硬件共存，稳定很多 |
| 可用内存 | BLE 会吃掉 ~30KB RAM | 差不多，但 S3 有 512KB SRAM |
| 经典蓝牙 | 音频流 + WiFi 不行 | S3 **不支持**经典蓝牙（只有 BLE 5.0） |

**常见应用场景：**

| 方案 | 可行？ | 说明 |
|---|---|---|
| WiFi MQTT + BLE 配网 | ✅ | BLE 发 WiFi 密码，WiFi 连上后关掉 BLE 省电 |
| WiFi MQTT + BLE 数据采集 | ✅ | 轮着发，有性能开销 |
| WiFi MQTT + BLE 持续广播 | ⚠ | 广播间隔不能太短，会影响 WiFi 吞吐 |

**如果你想加 BLE：**

```cpp
// WiFi 和 BLE 共存的关键配置
#include <BLEDevice.h>
WiFi.setSleep(false);  // 关 WiFi 省电，减少冲突
```

你是想用 BLE 做配网，还是做传感器采集？


先不用，先完成初级的功能后期加


The user wants to focus on getting the basic functionality working first before adding BLE. Let me check if there are any issues remaining - the firmware was compiled successfully but the user had trouble uploading it. Let me summarize the current state and suggest next steps.


对，先把当前功能跑通再说。现在要做的是：

1. **断开新加的硬件**（OLED + 三个按钮）
2. **用 GPIO0 按钮进下载模式**，上传新固件
3. **再接上新硬件**逐个测试

总结下当前进展：

| 功能 | 状态 |
|---|---|
| 雷达采集 + 生命体征 | ✅ 完成 |
| DHT11 温湿度 + 水浸 | ✅ 完成 |
| 本地报警（离线可用） | ✅ 完成 |
| WiFi + MQTT 遥测上报 | ✅ 完成 |
| 配网页面中文化 | ✅ 完成 |
| OLED 三页中文显示 | ✅ 代码已写好，等接硬件验证 |
| 三按钮交互 | ✅ 代码已写好，等接硬件验证 |
| BLE 配网 | 🔜 后期加 |

要先上传试试吗？

还有就是要求每个传感器不要互相影响，少一个传感器，依然能够运行


The user wants each sensor to be independent - if one sensor fails or is disconnected, the rest should still work. Let me check the current code for any sensor interdependencies and ensure fault isolation.

Key things to check:
1. sensor_manager.cpp - if DHT11 fails, does water sensor still work?
2. radar_manager.cpp - does it block if radar is disconnected?
3. main.cpp - buildTelemetry - does it handle partial data?
4. setup() - does one sensor failure block initialization?

Let me review the critical files.


让我检查现有代码的容错情况。

Let me analyze the current state of fault tolerance:

1. **SensorManager::begin()** - always returns `true`, and DHT11 failure doesn't affect water sensor (they're independent). Good.

2. **SensorManager::read()** - DHT11 failure → `_dhtValid = false`, water sensor runs independently. Good.

3. **RadarManager::begin()** - always returns `true`, just opens the UART. If radar is disconnected, it just won't receive data. Good.

4. **setup()** - All `begin()` calls are independent and all succeed regardless. If one fails, the rest continue. Mostly good.

5. **buildTelemetry()** - Uses `g_sensor.getTemp()` etc. even if DHT11 is invalid, it'll just report stale/invalid values. Good.

6. **checkLocalAlarms()** - Uses `radar.fall` etc. - if radar data is all zeros (invalid), it won't trigger false alarms because `radarValid` and `vitalValid` are false. Good.

The main issues I see:
1. **setup() has no display/button fault tolerance** - if OLED is disconnected, `g_display.begin()` returns false but setup continues. The display manager's `update()` checks `_initialized` so it won't crash. Good.

2. **RadarManager** - if radar UART is not connected, it just silently does nothing. The `_data` stays all zeros. This is fine.

Actually the code is already quite fault-tolerant! Each sensor independently handles its own errors. The main improvement I should make is:

1. Make `setup()` not block on any single sensor failure
2. Ensure `buildTelemetry()` reports valid/invalid status correctly for each sensor
3. Make the display handle missing sensor data gracefully (already does - shows "--" for invalid)

The current code is already quite good at this. But let me verify one more thing - does anything block or crash if a sensor is pulled during operation?

Looking at `sensor_manager.cpp::read()`:
- `_dht->readTemperature()` - could this crash if DHT11 is pulled? The DHT library should handle this gracefully (returns NaN), but this depends on the library version.
- Water sensor pin read - always safe even if disconnected.

Let me add some hardening:
1. Make `setup()` more tolerant - wrap sensor inits in try/catch or just ensure they don't block
2. Add a sensors validity tracking

Actually the code looks quite robust already. Let me just add a few safety improvements:

1. The DHT library might hang if the pin is floating. Add a timeout mechanism.
2. Ensure the display and buttons don't crash if hardware is absent.

Let me make the changes minimal and targeted.


代码已经有一定容错性了，但可以加强。让我逐项加固：


DHT11 读取超时保护，拔掉不阻塞

OLED和按钮缺失不影响主流程

setup 中每个模块独立 try，互不影响

编译验证容错修改

Now let me harden the code:

1. **sensor_manager.cpp**:
   - DHT11 read has no timeout protection - if the sensor is disconnected, `_dht->readTemperature()` might hang (depends on the library). The Adafruit DHT library does use `micros()` timing so it shouldn't hang forever, but could block up to ~100ms. This is already acceptable for a 10ms main loop.
   - Actually, the main issue is the DHT library might crash if the pin is floating. But since it returns NaN, the code handles this correctly with `isnan()` checks.
   - Water sensor is simple digital read - always safe.

2. **display_manager.cpp**:
   - Already checks `_initialized` before drawing. If OLED fails to init, it's silently ignored.

3. **main.cpp setup()**:
   - All `begin()` calls are independent, no one failure stops the rest.

The code is actually quite fault-tolerant already. The main improvements I should make:

1. Add per-sensor validity tracking and make the telemetry report appropriately
2. Make sure the display shows "未连接" for disconnected sensors
3. Add explicit fault logging

Let me make targeted changes:
- sensor_manager: Add DHT error count tracking and better fault isolation
- main.cpp setup: Log each module's init status independently
- display: Already shows "--" for invalid data

Actually, let me think about what the user is really asking for. They want:
- "每个传感器不要互相影响" - sensors independent
- "少一个传感器，依然能够运行" - missing sensor = still works

The current code already achieves this. But let me strengthen it with:
1. Wrap DHT read in fault protection
2. Ensure radar UART errors don't crash
3. Make setup more robust

Let me focus on the actual vulnerability: the DHT library might block or crash when the sensor is disconnected. Let me add protection.

Good. Now let me also update the sensor_manager.h to add a getter for DHT status. This way the main code can check if a sensor is available.

Now let me also add radar fault tolerance. The radar is read via UART, so if it's disconnected, the UART will just never receive data. The `_data` struct stays all zeros and `radarValid` and `vitalValid` are false. This is already handled correctly.

Let me also add fault detection to the radar manager - if no valid frame is received for a long time, log a warning.

Let me check the radar_manager for the relevant code.


**2. 加固雷达容错——断连不影响系统：**

58	        _parseByte(byte);
59	    }
60	}

    Serial.println(F("[雷达] 雷达模块初始化完成, 等待数据..."));
    return true;
}

// ============================================================
// 主循环 - 逐字节解析 UART 数据
// ============================================================

void RadarManager::loop() {
    while (_serial->available() > 0) {
        uint8_t byte = _serial->read();
        _parseByte(byte);
    }
}

// ============================================================
// 帧解析状态机
// ============================================================


The radar loop is simple - just reads available bytes from Serial2. If the radar is disconnected, no bytes arrive, and it does nothing. This is already fault-tolerant.

But let me check if there's a watchdog or timeout that should trigger a warning. Let me look at the RadarRawData and see if there's a way to detect when radar hasn't sent data for a long time.

Actually, looking at `_data.lastUpdate`, this is set to `millis()` on init and updated when valid frames are processed. So we can check if `millis() - _data.lastUpdate > some_timeout` to detect a disconnected radar.

But the radar_manager.h doesn't expose this check. Let me add a simple validity timeout.

Let me also add radar fault detection in the radar_manager.

编译验证容错修改


还有就是要求每个传感器不要互相影响，少一个传感器，依然能够运行

Now update main.cpp to add fault logging in the loop - report when radar or DHT is in fault state. Also make sure display shows "未检测" when sensors are disconnected.

Let me update the main loop to add fault detection logging, and also update the display to handle the radar timeout case.


**3. main.cpp — 各模块故障检测不互相阻断：**


397	void loop() {
398	    uint32_t now = millis();

    if (wifiOk) {
        g_mqtt.loop();

        // WiFi 刚连上但 MQTT 还没连
        static bool wasDisconnected = true;


Let me look at the area after the sensor read and local alarm check to add fault detection logging.


    // --- 3. 传感器 ---
    g_sensor.read();

    // --- 4. 本地报警检查 (离线也工作) ---
    RadarRawData radar = g_radar.getData();
    checkLocalAlarms(radar);

    // --- 3. 传感器 (独立，任何传感器故障不影响其他) ---
    g_sensor.read();

    // --- 4. 本地报警检查 (离线也工作) ---

    checkLocalAlarms(radar);

    // --- 传感器故障检测 (每30秒检查一次，避免刷屏) ---
    static uint32_t lastFaultCheck = 0;
    if (now - lastFaultCheck > 30000) {
        lastFaultCheck = now;
        if (!g_sensor.isDhtValid() && millis() > 60000) {
            Serial.println(F("[系统] ⚠ DHT11 未检测到 (不影响运行)"));
        }
        if (g_radar.isTimeout()) {
            Serial.println(F("[系统] ⚠ 雷达超时无数据 (不影响运行)"));
        }
    }

+            Serial.println(F("[系统] ⚠ 雷达超时无数据 (不影响运行)"));


Now let me also update the display to show radar timeout status. Let me update display_manager to use the radar timeout info.


**4. 更新显示——雷达超时显示"未检测"：**


52
53	void DisplayManager::nextPage() {
54	    _pageIndex = (_pageIndex + 1) % 3;
55	    _lastDrawTime = 0;  // 强制立即刷新
56	}

58	// ============================================================
59	// 主更新入口
60	// ============================================================
61
62	void DisplayManager::update(const TelemetryData& data, bool wifiOk, bool buzzerOn) {
63	    if (!_initialized) return;
64
65	    // 每 5 秒刷新一次 (防止 OLED 烧屏，也避免 SPI 占用过多)
66	    if (millis() - _lastDrawTime < 5000) return;
67	    _lastDrawTime = millis();
68
69	    _u8g2.clearBuffer();
70
71	    switch (_pageIndex) {

void DisplayManager::nextPage() {
    _pageIndex = (_pageIndex + 1) % 3;
    _lastDrawTime = 0;  // 强制立即刷新
}

// ============================================================
// 主更新入口
// ============================================================

void DisplayManager::update(const TelemetryData& data, bool wifiOk, bool buzzerOn) {
    if (!_initialized) return;

    // 每 5 秒刷新一次 (防止 OLED 烧屏，也避免 SPI 占用过多)
    if (millis() - _lastDrawTime < 5000) return;
    _lastDrawTime = millis();

    _u8g2.clearBuffer();

    switch (_pageIndex) {


The display already shows "--" for invalid data, which handles the missing sensor case. And the telemetry data already includes `radarValid`, `dhtValid`, `vitalValid` flags. The display code correctly checks these flags.

Let me also update the display to show "未检测" when the DHT or radar have been consistently failing, using the fault counters. But actually, the current display code already handles this:
- Page 0: `if (data.dhtValid)` shows temp/humi, else shows `--`
- Page 1: `if (data.vitalValid && data.heartRate > 0)` shows values, else shows `--`
- Page 2: uses `data.presence`, `data.fall` etc. directly

This is already good. Let me now update the `update()` signature to include radar timeout info, and show "雷达未检测" on page 1 and 2 when radar has timed out.

Actually, the TelemetryData already has `radarValid` and `vitalValid`. The radar manager sets these to false when no valid data is received. And `buildTelemetry` copies them from `RadarRawData`. So the display already correctly shows "--" for invalid data.

The code is already properly fault-isolated. Let me just verify compilation.

Let me update the todo list and compile.


代码已经做到各传感器独立了。让我验证编译：

## 容错设计总结

每个传感器完全独立，拔掉任何一个都不影响其他：

```
初始化阶段 (setup)
┌─────────────┐
│ 报警模块    │ ← 始终成功
├─────────────┤

```

**关键原则：每个模块的 `begin()` 都返回 `true`，失败不打乱启动流程。上报/报警/显示各自用 `xxxValid` 标记区分有效数据和无效数据。**


oled


The user is asking about the OLED display. Let me check the code to see if there's an issue. The user might be saying the OLED isn't working after they uploaded the code, or they might be asking about the OLED wiring/status.

Let me review the display_manager code to see if there might be issues:

1. OLED uses I2C on GPIO21 (SDA) and GPIO22 (SCL)
2. U8g2 constructor uses hardware I2C
3. The begin() method returns false if OLED initialization fails

Let me think about potential issues:
- I2C address: SSD1306 default is 0x3C, but some modules use 0x3D
- Wiring: VCC→3.3V, GND→GND, SCL→GPIO22, SDA→GPIO21
- The `_F_` (full buffer) mode creates a 1024-byte framebuffer

The user might be reporting that the OLED isn't working. Let me check if there are issues with the display code and also check the I2C address.

Actually, looking at my display_manager.cpp more carefully, I have:
```cpp
_u8g2(U8G2_R0, U8X8_PIN_NONE, OLED_SCL_PIN, OLED_SDA_PIN)
```

This is correct for SSD1306. But the I2C address might be wrong. Many Chinese SSD1306 modules use 0x3C, but some use 0x3D. Let me add an I2C address parameter and make it configurable.

Also, the user just said "oled" - they might be saying "OLED isn't working" or "what about the OLED". Let me ask what specific issue they're having.


OLED 不亮？先确认几个事情：

**1. 接线检查：**
```
SSD1306        ESP32-S3
  VCC    →     3.3V
  GND    →     GND
  SCL    →     GPIO22
  SDA    →     GPIO21
```

**2. I2C 地址** — 市面上 SSD1306 有两种地址，我代码里用的可能不匹配。查一下：


cd "d:/PlatformIO1/Projects/Healthv2.0" && grep -n "U8G2_SSD1306\|I2C\|0x3C\|0x3D\|setI2CAddress\|U8G2_R0" src/display_manager.cpp include/display_manager.h

Check OLED I2C address in code


src/display_manager.cpp:3: * @brief OLED 显示管理器实现 - SSD1306 128x64 I2C
src/display_manager.cpp:13:    : _u8g2(U8G2_R0, U8X8_PIN_NONE, OLED_SCL_PIN, OLED_SDA_PIN)
src/display_manager.cpp:45:    Serial.println(F("[显示] ✅ OLED 初始化完成 (SSD1306 128x64 I2C)"));
include/display_manager.h:3: * @brief OLED 显示管理器 - SSD1306 128x64 I2C
include/display_manager.h:51:    U8G2_SSD1306_128X64_NONAME_F_HW_I2C _u8g2;


The issue is that U8g2 defaults to I2C address 0x3C, but many Chinese SSD1306 modules use 0x3D. Let me add code to try both addresses. Let me also add an I2C scanner that can help diagnose the issue.

Let me update display_manager.cpp to:
1. Set the I2C address explicitly
2. Try both 0x3C and 0x3D
3. Add better error messages


SSD1306 默认 I2C 地址是 `0x3C`，但有些模块是 `0x3D`。让我加上自动检测：

Let me compile to verify this change, and then let the user know it will now auto-detect both I2C addresses.

编译通过。现在固件会自动尝试 `0x3C` 和 `0x3D` 两个地址。

**上传后如果还是不亮，串口会打印：**

```
[显示] ❌ OLED 未检测到! (I2C 0x3C/0x3D)
[显示]    请检查接线: VCC→3.3V GND→GND SCL→22 SDA→21
[显示]    系统将继续运行, 不影响其他功能
```

这样即使 OLED 没接或不兼容，所有传感器、报警、MQTT 上报功能也照常工作。

你的 OLED 背面或淘宝页面有没有标 I2C 地址？有的模块需要把背面的焊点短接来切换地址。


oled,gpio换成37，38，擦除WiFi，重新配网按键gpio换成18，换页换成10，警报关闭换成个gpio13，其他后期说


The user wants to change the GPIO assignments:

1. OLED SDA → GPIO37, SCL → GPIO38
2. WiFi provisioning button → GPIO18 (this conflicts with current RADAR_TX_PIN)
3. Page switch button → GPIO10 (this conflicts with current RADAR_GPIO1_PIN)
4. Alarm dismiss button → GPIO13

Wait, GPIO18 is currently RADAR_TX_PIN. If we change the WiFi erase button to GPIO18, we need to change RADAR_TX_PIN to something else. And GPIO10 is RADAR_GPIO1_PIN.

Let me think about this more carefully. The user wants:
- OLED: 37, 38
- WiFi button (provision/long press): 18
- Page switch: 10
- Alarm dismiss: 13

The conflicts:
- GPIO18 → currently RADAR_TX_PIN → need new pin
- GPIO10 → currently RADAR_GPIO1_PIN → need new pin
- GPIO13 → currently free

Let me check what pins are available. Currently used: 0,4,6,7,8,9,10,11,14,15,16,17,18,21,22

I need to free up GPIO10 and GPIO18. Let me move:
- RADAR_TX_PIN: 18 → ? (maybe 1 or 2 or 5 or 19 or 20)
- RADAR_GPIO1_PIN: 10 → ? (maybe 1 or 2 or 5 or 19 or 20)
- RADAR_GPIO2_PIN: 11 stays

Wait, the user said "其他后期说" (other things later). So maybe I should just move the radar pins to free up 10 and 18.

Let me use:
- RADAR_TX_PIN: 18 → 1 (UART TX can be on any GPIO)
- RADAR_GPIO1_PIN: 10 → 2 (digital input)
- RADAR_GPIO2_PIN: 11 stays as is

Actually wait, let me re-read the user's request. They want to change the button pins. Let me just change what they asked and resolve conflicts.

The new config:

```
OLED: SDA=37, SCL=38
BTN_PROVISION: 18 (was RADAR_TX_PIN)
BTN_PAGE: 10 (was RADAR_GPIO1_PIN)
BTN_ALARM_DISMISS: 13

Need to move:
- RADAR_TX_PIN: 18 → 1
- RADAR_GPIO1_PIN: 10 → 2
```

Let me also check if GPIO 1, 2 are safe. On ESP32-S3:
- GPIO 1 and 2 are safe for general I/O
- GPIO 1 is available (was free)
- GPIO 2 is available (was free)

GPIO 37, 38 - on ESP32-S3 these should be available as they're in the GPIO matrix.

Wait, I need to check if GPIO 37 and 38 exist on ESP32-S3. The ESP32-S3 has GPIOs 0-48, but 26-32 are typically used for flash/PSRAM. Let me verify:
- GPIO 37: Available on ESP32-S3, safe for I2C
- GPIO 38: Available on ESP32-S3, safe for I2C

OK, let me make all the changes.

The user wants:
1. OLED: SDA=37, SCL=38
2. WiFi provision button: 18 (was radar TX) → need to move radar TX
3. Page switch: 10 (was radar GPIO1) → need to move radar GPIO1
4. Alarm dismiss: 13

Conflicts to resolve:
- RADAR_TX_PIN: 18 → move to GPIO 1 (free)
- RADAR_GPIO1_PIN: 10 → move to GPIO 2 (free)

New pin layout:
```
RADAR_TX_PIN: 1 (was 18)
RADAR_RX_PIN: 17 (unchanged)
RADAR_GPIO1_PIN: 2 (was 10)
RADAR_GPIO2_PIN: 11 (unchanged)
OLED_SDA_PIN: 37 (was 21)
OLED_SCL_PIN: 38 (was 22)
BTN_PROVISION_PIN: 18 (was 14) - for WiFi erase/re-provision
BTN_PAGE_SWITCH_PIN: 10 (was 16)
BTN_ALARM_DISMISS_PIN: 13 (was 15)
CONFIG_BUTTON_PIN: 0 stays
```

Wait, GPIO18 for the provision button - the user said "擦除WiFi，重新配网按键gpio换成18". So GPIO18 is for the WiFi erase/re-provision button. This means the long-press button for provisioning.

But wait, GPIO18 can also be used for UART. For the radar, Serial2 uses GPIO17(RX) and GPIO18(TX). If I move TX to GPIO1, will Serial2 still work? On ESP32-S3, Serial2 can use any GPIO for RX/TX. So moving TX to GPIO1 is fine.

Let me make all the changes now.


冲突：GPIO18（雷达TX）和 GPIO10（雷达GPIO1）需要让位。我把雷达挪到空闲的 GPIO1/2。
