# CAN 总线调试

## 适用场景

- 嵌入式设备实现了 CAN 通信,需要验证收发是否正常。
- 需要监听 CAN 总线上的所有帧或过滤特定 ID。
- 需要向 CAN 总线发送测试帧并等待响应。
- 需要扫描总线上的活跃节点。

## 必要输入

- CAN 接口类型(pcan、kvaser、slcan、socketcan、virtual 等)。
- 通道名(取决于接口类型,如 PCAN_USBBUS1、COM3、can0)。
- 波特率(默认 500000)。

## 依赖

- `python-can`(pip install python-can)
- 对应适配器的驱动(如 PCAN 需要 PCAN-Basic API)

## 执行步骤

1. 先阅读 [references/usage.md](references/usage.md),确认操作参数。
2. 探测环境:
   ```bash
   python scripts/can_tool.py --detect
   ```
3. 根据需求执行操作:
   ```bash
   # 监听总线
   python scripts/can_tool.py --interface pcan --channel PCAN_USBBUS1 --listen --duration 10

   # 发送帧
   python scripts/can_tool.py --interface pcan --channel PCAN_USBBUS1 --send --id 0x123 --data 01,02,03

   # 扫描节点
   python scripts/can_tool.py --interface pcan --channel PCAN_USBBUS1 --scan --scan-range 0x001-0x0FF
   ```

## 失败分流

- `connection-failure`:适配器未连接或驱动未安装。
- `bus-error`:CAN 总线错误(如未接终端电阻)。
- `timeout`:发送后无响应。

## 输出约定

示例输出格式:

```
结果: ✅ 监听完成,收到 15 帧
  连接: pcan PCAN_USBBUS1 500000

  [14:30:01] 0x123  [8]  01 02 03 04 05 06 07 08
  [14:30:01] 0x456  [4]  AA BB CC DD
```

## 交接关系

- 从 `build-keil` / `build-platformio` 烧录固件后,用此 skill 验证 CAN 通信。
- 与 `serial-monitor` 互补:serial-monitor 查看串口调试输出,can-debug 进行 CAN 协议级调试。
