Array in Tasks make a Guru error with ESP32

问题

Here's the translation of the code and the error message:

所以，我为这个ESP32编写了一个程序。它有一些任务，其中一个让我遇到了一些麻烦。它给我发送了一个Guru错误。以下是代码：
main.cpp：

#include <Arduino.h>

    gGPS();
  }
}

void setaktor(void * par){ // 用于获取动力装置的任务
  for(;;){
    gmotor();
    /*LEDsss(dark);

  }
}

    Sperre = true;
    U = true;
    O = false;
  } else {
    Sperre = false;
  }
  delay(10);
}

Mittelwert任务给我带来了问题：
Mittelwert.h：

#include <Arduino.h>

bool getthreeminutes = false;

int halfhouri = 0;
int threemini = 0;

double sensors[] = {gotHum, gotLux, gotTemp, gotwindgeschwingkeit};
double sensorshh[sizeof(sensors)];
double sensorstm[sizeof(sensors)];

void mittelsetup(){
    for(int i = sizeof(sensors) - 1; i >= 0; i--){
        sensorshh[i] = sensors[i];
        sensorstm[i] = sensors[i];
    }
}

void updatesenorssss(){
    sensors[0] = gotHum;
    sensors[1] = gotLux;
    sensors[2] = gotTemp;
    sensors[3] = gotwindgeschwingkeit;
}

void gMittelwerte(){
    updatesenorssss();
    vTaskDelay(1000/portTICK_PERIOD_MS);

    halfhouri++;
    threemini++;

    for(int i = sizeof(sensors) - 1; i >= 0; i--){
        sensorshh[i] += sensors[i];
        sensorstm[i] += sensors[i];
    }

    if(gethalfhour){
        for(int i = sizeof(sensors) - 1; i >= 0; i--){
            sensorshh[i] = sensorshh[i] / halfhouri;
        }
        halfhouri = 0;
        vTaskDelay(500/portTICK_PERIOD_MS);
        for(int i = sizeof(sensorshh) - 1; i >= 0; i--){
            sensorshh[i] = 0;
        }
    }
    if(getthreeminutes){
        for(int i = sizeof(sensors) - 1; i >= 0; i--){
            sensorstm[i] = sensorstm[i] / threemini;
        }
        threemini = 0;
        vTaskDelay(500/portTICK_PERIOD_MS);
        for(int i = sizeof(sensorstm) - 1; i >= 0; i--){
            sensorstm[i] = 0;
        }
    }
}

如果我不启动Mittelwert任务，一切都正常运行。所以我不知道发生了什么，我尝试找出错误，但是正如你所看到的，我是一个初学者。

这是错误代码：

So, i wrote a Programm for this esp32. It has some Tasks and one get me in some trouble. It sends me a Guru error. Here the code:

}else{

}


the Task Mittelwert is giving me the problems:

int halfhouri = 0;

double sensors[]={gotHum, gotLux, gotTemp, gotwindgeschwingkeit};
double sensorshh[sizeof(sensors)];
double sensorstm[sizeof(sensors)];

void mittelsetup(){
for(int i = sizeof(sensors)-1; i>=0; i--){

sensorstm[i]=sensors[i];
}
}

void updatesenorssss(){
sensors[0]=gotHum;

}

void gMittelwerte(){

vTaskDelay(1000/portTICK_PERIOD_MS);

    halfhouri++;
threemini++;
for(int i = sizeof(sensors)-1; i&gt;=0; i--){

}
if(gethalfhour){

halfhouri=0;

vTaskDelay(500/portTICK_PERIOD_MS);
for(int i = sizeof(sensorstm)-1; i&gt;=0; i--){
sensorstm[i]=0;
}
}

}

If I dont start the Task it funktions perfektly fine. So i dont know what is happening, i tried to find the error but, as you can see, I am an beginner.
Here the errorcode:

Thank you for your Help!!
And also, i am Austrian, so my English is not the best.
I tried to commend some parts out too find the problem and was left wiht the Mittelwert.h. I couldn find out whats specificly wrong with it. SO if someone finds the problem pleas tell me. The first error was a WatchDog error, witch i safed with the Idle_Priority, but then ther was the Guru error.

问题出在你使用`sizeof`运算符与`sensors`数组的方式上。
`sensors`是一个包含4个double值的数组，假设每个double需要8字节的内存，那么`sizeof(sensors)`将返回8x4=32，而不是你期望的4。因此，在你的for循环中，你尝试访问数组中超出你定义的4个元素限制的位置，导致你得到的`LoadProhibited`错误。
要获取数组的实际长度，你应该使用`sizeof(sensors) / sizeof(sensors[0])`。
```c
double sensors[] = {1, 2, 3, 4};
printf("sizeof(sensors) = %ld\n", sizeof(sensors)); // 输出：sizeof(sensors) = 32
printf("数组长度 = %ld\n", sizeof(sensors) / sizeof(sensors[0])); // 输出：数组长度 = 4
英文:

The issue is in the way you are using the sizeof operator with the sensors array.

sensors is an array of 4 double values, assuming each double requires 8 bytes of memory, then sizeof(sensors) will return 8x4=32, not the 4 you are expecting. As a result, in your for loops, you try to access a position in the array that is beyond the limits of the 4 elements you defined, resulting in the LoadProhibited error you get.

To get the actual length of the array, you should use sizeof(sensors) / sizeof(sensors[0]).

double sensors[] = {1, 2, 3, 4};
printf(&quot;sizeof(sensors) = %ld\n&quot;, sizeof(sensors)); // Output: sizeof(sensors) = 32
printf(&quot;Array length = %ld\n&quot;, sizeof(sensors) / sizeof(sensors[0])); // Output: Array length = 4
