EEPROM读取debug不正常release正常

这个超级无语,研究和半天,突然发现调到release就正常了,表现为写入看起来正常读取不正常,这个无语了,不想研究了

STVP下载不能够成功运行

现在我都只用三根线来调试仿真!

定时器消抖莫名其妙的跑不通流程

这里做了一个定时器消抖功能,但是莫名其妙的无语了,竟然跑不通消抖算法,IO中断函数设置标志位:

/**
  * @brief External Interrupt PORTB Interrupt routine.
  * @param  None
  * @retval None
  */
INTERRUPT_HANDLER ( EXTI_PORTB_IRQHandler, 4 )
{
        /* In order to detect unexpected events during development,
           it is recommended to set a breakpoint on the following instruction.
        */
  if(GPIO_ReadInputPin(KEY_LIGHTN_GPIO,KEY_LIGHTN_PIN)==0)
  {
    //uart_printf("KEY_LIGHTN Irq\r\n" );
    key_judge=KEY_TYPE_LIGHTN;
  }
  if(GPIO_ReadInputPin(KEY_SWITCHP_GPIO,KEY_SWITCHP_PIN)==0)
  {
    //uart_printf("KEY_SWITCHP Irq\r\n" );
    key_judge=KEY_TYPE_SWITCHP;
  }
}

/**
  * @brief External Interrupt PORTC Interrupt routine.
  * @param  None
  * @retval None
  */
INTERRUPT_HANDLER ( EXTI_PORTC_IRQHandler, 5 )
{
        /* In order to detect unexpected events during development,
           it is recommended to set a breakpoint on the following instruction.
        */
  if(GPIO_ReadInputPin(KEY_LIGHTP_GPIO,KEY_LIGHTP_PIN)==0)
  {
    //uart_printf("KEY_LIGHTP Irq\r\n" );
    key_judge=KEY_TYPE_LIGHTP;
  }
  if(GPIO_ReadInputPin(KEY_SWITCHN_GPIO,KEY_SWITCHN_PIN)==0)
  {
    //uart_printf("KEY_SWITCHN Irq\r\n" );
    key_judge=KEY_TYPE_SWITCHN;
  }
}

/**
  * @brief External Interrupt PORTD Interrupt routine.
  * @param  None
  * @retval None
  */
INTERRUPT_HANDLER ( EXTI_PORTD_IRQHandler, 6 )
{
        /* In order to detect unexpected events during development,
           it is recommended to set a breakpoint on the following instruction.
        */
  if(GPIO_ReadInputPin(KEY_OnOff_GPIO,KEY_OnOff_PIN)==0)
  {
    //uart_printf("KEY_OnOff Irq\r\n" );
    key_judge=KEY_TYPE_OnOff;
  }
}

定时器中断设置标志位,然后在while主循环调用消抖函数:

// 定时器 20ms
void TIMER_Initializes( void )
{
        TIM2_TimeBaseInit( TIM2_PRESCALER_16, 20000 ); 
        TIM2_ClearFlag( TIM2_FLAG_UPDATE );            //清除标志位
        TIM2_ITConfig( TIM2_IT_UPDATE, ENABLE );       //使能更新UPDATE中断
        enableInterrupts();                       //使能全局中断
        TIM2_SetCounter( 0 );                          //计数值归零
        TIM2_Cmd( ENABLE );                            //启动定时器
}
uint16_t _ticks = 0;
INTERRUPT_HANDLER ( TIM2_UPD_OVF_BRK_IRQHandler, 13 )
{
        /* In order to detect unexpected events during development,
           it is recommended to set a breakpoint on the following instruction.
        */

        TIM2_ClearITPendingBit ( TIM2_IT_UPDATE );     //清除中断标志

        _ticks++;
        timer_bit_flag.timer20ms_flag = 1;
        if ( _ticks % 25 == 0 )
        {
                timer_bit_flag.timer500ms_flag = 1;
        }
        else if ( _ticks % 50 == 0 )
        {
                timer_bit_flag.timer1000ms_flag = 1;
        }
}
void main ( void )
{
        uint8_t uart_rec_len;
        CLK_DeInit();
        CLK_LSICmd ( ENABLE );
        CLK_HSICmd ( ENABLE );
        while ( SET != CLK_GetFlagStatus ( CLK_FLAG_HSIRDY ) );
        CLK_SYSCLKConfig ( CLK_PRESCALER_CPUDIV1 );
        CLK_HSIPrescalerConfig ( CLK_PRESCALER_HSIDIV1 ); //HSI = 16M (1分频)
        GPIO_Configuration();
        TIMER_Initializes();
        UART_Initializes();
        //ADC_Initializes();
        eeprom_init();
        timer1_init();
        
        enableInterrupts();                       //使能全局中断
		if(g_config.PowerOff)
		{
			rgb_SetCompare(0,0,0);
			uart_printf("Device PowerOff\r\n");
		}
        while ( 1 )
        {
                if ( timer_bit_flag.timer20ms_flag == 1 )
                {
                        timer_bit_flag.timer20ms_flag = 0;
                        user_timer_handler();
                }

消抖函数处理完成后调用key_handle函数进行处理,这里出现一个莫名其妙的问题,竟然没有进入下面的语句清除变量,无语了,我的天了,老哥撸代码十来年,搞了大半天,投降了,最后用了在中断中直接进行定时器消抖,无语了!记录再次,以后如果悟到了再来改

int8_t key_state_read(void) 
{
  switch(key_judge)
  {
    case KEY_TYPE_LIGHTP:
      if(GPIO_ReadInputPin(KEY_LIGHTP_GPIO,KEY_LIGHTP_PIN)==0) return ((uint8_t)KEY_TYPE_LIGHTP);
      else return 0;
    case KEY_TYPE_LIGHTN:
      if(GPIO_ReadInputPin(KEY_LIGHTN_GPIO,KEY_LIGHTN_PIN)==0) return ((uint8_t)KEY_TYPE_LIGHTN);
      else return 0;
    case KEY_TYPE_SWITCHP:
      if(GPIO_ReadInputPin(KEY_SWITCHP_GPIO,KEY_SWITCHP_PIN)==0) return ((uint8_t)KEY_TYPE_SWITCHP);
      else return 0;
    case KEY_TYPE_SWITCHN:
      if(GPIO_ReadInputPin(KEY_SWITCHN_GPIO,KEY_SWITCHN_PIN)==0) return ((uint8_t)KEY_TYPE_SWITCHN);
      else return 0;
    case KEY_TYPE_OnOff:

      else return 0;
  default:
     return 0;
  }

            key_loop++;

                //uart_printf("loop long\r\n");
				key_handle(key_judge,KEY_ACTION_LONG);
				key_loop=0;
