Question

由于arduino上没有调试实用程序（或者至少我不熟悉），因此很难按照代码查看它停止的位置... 下面我添加了我的设置功能。在内部设置中我创建了一个init类的对象..它的构造函数负责初始化任务时间等的EEPROM数据。但是通过添加几个串行输出，我发现程序不会脱离init类。当我评论init时，一切正常。我检查了所有init类的行，但没有发现问题

       void setup() {

         Serial.begin(9600);
       pinMode(ARM_BUTTON_PIN,INPUT);
    Serial.println("start");
    //   EEPROM.put(PACKET_COUNT_EEPROM, 0);

 Init init;
 Serial.println("before Contoll");

controller= new Controller();


Serial.println("setup");

delay(200);}

这是init.cpp：

   #include "constants.h"
   #include "Sampler.h"
    #include "SDLogger.h"
   #include "Controller.h"
    #include "Init.h"

/*
 * EEPROM Structure
 * 0: @: 0 mission Time(s) uint16_t
 * 1: @: sizeof(uint16_t) packetCount uint16_t
 * 2: @: sizeof(uint16_t)+ sizeof(uint16_t) stateCode uint8_t
 * 3: @: sizeof(uint16_t)+ sizeof(uint16_t) + sizeof(uint8_t)  refAltitude int16_t 
#define MISSION_TIME_EEPROM 0
#define PACKET_COUNT_EEPROM sizeof(uint16_t)
#define STATE_CODE_EEPROM sizeof(uint16_t)+ sizeof(uint16_t) 
#define REF_ALTITUDE_EEPROM sizeof(uint16_t)+ sizeof(uint16_t) + sizeof(uint8_t) 
 */

 Init::Init(){
    Sampler sampler;
    uint16_t missionEEPROMTime ;
    EEPROM.get(MISSION_TIME_EEPROM, missionEEPROMTime);

      Serial.println("init");
delay(100);
    if(!digitalRead(ARM_BUTTON_PIN)){

  if( missionEEPROMTime == 0 ){
    //initiate reset
    Serial.println("armed0");

    resetSystem();
    Serial.println("befin");
delay(100);

    initializeSystem();
    Serial.println("befres");

    Controller::startTime = 0;
  }  else{
    Serial.println("armednot0");

    //recover
    recoverSystem();
    Controller::startTime = missionEEPROMTime;
  }
    }else{
      Serial.println("not arm");

              resetSystem();
              Controller::startTime = 0;
         EEPROM.put(REF_ALTITUDE_EEPROM, sampler.readAltitude());
              // Serial.println(sampler.readAltitude());

        // while(1);
    }

  }


     Init::resetSystem(){
          Sampler sampler;

  for (int i = 0 ; i < EEPROM.length() ; i++) {
    EEPROM.write(i, 0);
  }
           EEPROM.put(REF_ALTITUDE_EEPROM, sampler.readAltitude());

    }
    Init::initializeSystem(){
      delay(100);
              Serial.println("vbqdfewf");


           Serial.println("initSample");

        EEPROM.put(MISSION_TIME_EEPROM, 0);
        EEPROM.put(PACKET_COUNT_EEPROM, 0);
        EEPROM.put(STATE_CODE_EEPROM, 0);
       // EEPROM.put(REF_ALTITUDE_EEPROM, sampler.readAltitude());
       // SDLogger::initCSV(0);
       // SDLogger::initIMG(0);
       // SDLogger::beginBus();
        Serial.println("inited");
    }
   Init::recoverSystem(){
      //  SDLogger::initCSV(1);
      //  SDLogger::initIMG(1);
      //  SDLogger::beginBus();

  }

和init.h：

 #ifndef Init_h
  #define Init_h

  #include "constants.h"
  #include "Sampler.h"
  #include "SDLogger.h"
  #include "Controller.h"

  /*
   * EEPROM Structure

   * 1: @: sizeof(uint16_t) packetCount uint16_t
   * 2: @: sizeof(uint16_t)+ sizeof(uint16_t) stateCode uint8_t
   * 3: @: sizeof(uint16_t)+ sizeof(uint16_t) + sizeof(uint8_t)  refAltitude int16_t 
  #define MISSION_TIME_EEPROM 0
  #define PACKET_COUNT_EEPROM sizeof(uint16_t)
  #define STATE_CODE_EEPROM sizeof(uint16_t)+ sizeof(uint16_t) 
  #define REF_ALTITUDE_EEPROM sizeof(uint16_t)+ sizeof(uint16_t) + sizeof(uint8_t) 
   */
  class Init {
    public:
    Init();


    private:
      resetSystem();
      initializeSystem();
    recoverSystem();

  };
  #endif

当我执行init init时，

其他类在采样器和公墓中工作正常。所以他们没有问题。

Answer 1

这也称为Static Initialzation Order Fiasco。您必须分离对象的构造（在setup之前发生的事情）及其初始过程（在setup或更晚的版本中）。

例如，Serial和许多其他类都有begin()或init()方法，可以从草图中明确调用。

arduino上的草图停止在对象构造函数中执行
