Member Function Documentation

Feed()

virtual ErrorCode LibXR::Watchdog::Feed ( )

pure virtual

立即手动喂狗 Feed the watchdog immediately

Returns

操作结果的错误码 Error code of the operation

Implemented in LibXR::STM32Watchdog.

SetConfig()

virtual ErrorCode LibXR::Watchdog::SetConfig ( const Configuration & config )

pure virtual

初始化硬件并设置超时时间 Initialize hardware and set overflow time

Parameters

config

配置参数 Configuration

Returns

操作结果的错误码 Error code of the operation

Implemented in LibXR::STM32Watchdog.

Start()

virtual ErrorCode LibXR::Watchdog::Start ( )

pure virtual

启动看门狗 / Start the watchdog

Implemented in LibXR::STM32Watchdog.

Stop()

virtual ErrorCode LibXR::Watchdog::Stop ( )

pure virtual

停止看门狗 / Stop the watchdog

Implemented in LibXR::STM32Watchdog.

TaskFun()

static void LibXR::Watchdog::TaskFun ( Watchdog * wdg )

inlinestatic

Watchdog 自动喂狗定时器任务函数 Watchdog timer task function for auto-feeding.

适合轮询/定时任务调度环境。可直接作为Timer/Task回调，每次被调度时喂狗一次。 Suitable for cooperative/periodic polling system. Called by timer, feeds the watchdog once per call.

Parameters

wdg	指向 Watchdog 实例的指针 Pointer to the Watchdog instance

Definition at line 101 of file watchdog.hpp.

  {
    if (wdg->auto_feed_)
    {
      wdg->Feed();
    }
  }

ThreadFun()

static void LibXR::Watchdog::ThreadFun ( Watchdog * wdg )

inlinestatic

Watchdog 自动喂狗线程函数 Watchdog thread function for auto-feeding.

适合 RTOS/多线程环境。可直接传递给线程创建API作为入口，循环调用 Feed()，每隔 feed_ms 毫秒自动喂狗。 Suitable for RTOS or multi-threading. Call by thread system, periodically feeds the watchdog.

Parameters

wdg	指向 Watchdog 实例的指针 Pointer to the Watchdog instance

Definition at line 78 of file watchdog.hpp.

  {
    while (true)
    {
      if (wdg->auto_feed_)
      {
        wdg->Feed();
      }
      LibXR::Thread::Sleep(wdg->feed_ms_);
    }
  }
