我有一个大师错误，当我试图编译和上传这段代码，这只是代码的一部分，但错误是在这一部分。
在模拟和我的esp 32开发工具包中，我得到了相同的错误！

当一个向上这个代码到一个esp 32我有这个错误

这只是代码的一部分，但问题就出在这方面！
使用exception解码器，我得到这个错误：

您应该在loop()中使用延迟，而不是使用busy-wait循环。在该循环中，任何启用的看门狗都不会得到服务，并且任何较低/同等优先级的任务都将被阻止运行：

void loop() 
{
  vTaskDelay( 1 ) ;  // do nothing, allow scheduler to run
}

字符串
我知道在ESP 32上的platformio中，setup()和loop()本身运行在RTOS上下文中。
您的taskLeituraSensor()运行到完成并返回-这不是任务函数的常见行为-通常任务在无限循环中运行。任务至少应删除自身以在终止时恢复资源：

void taskLeituraSensor(void * pvParameters)
{
  .
  .
  .

  vTaskDelay(pdMS_TO_TICKS(3000)); 
  vTaskDelete(0) ;  // Delete self
}

型
在任何情况下，如果任务在任何情况下简单地终止，则根本不清楚延迟的目的是什么。
更常见的任务结构是：

void taskLeituraSensor(void * pvParameters)
{
  for(;;)
  {
    .
    .
    .

    vTaskDelay(pdMS_TO_TICKS(3000)); 
  }
}

型
或者，如果任务打算在某个点终止：

void taskLeituraSensor(void * pvParameters)
{
  bool terminate = false ;

  while( !terminate )  // Run until terminated
  {
    .
    .
    .

    vTaskDelay(pdMS_TO_TICKS(3000)); 
  }

  vTaskDelete(0) ;  // Delete self on terminate
}
