大家帮我看看,我的AD程序一直卡在校准的位置,怎么破?

#include "bsp_adc.h"

void ADC1_IN1_Config(void)
{
       unsigned intcalibration_value = 0;
        GPIO_InitTypeDef    GPIO_InitStructure;
        ADC_InitTypeDef       ADC_InitStructure;
ADC_CommonInitTypeDef ADC_CommonInitStructure;
        RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE);
       
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 ;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AN;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL ;
GPIO_Init(GPIOA, &GPIO_InitStructure);
       
       


    /* Configure the ADC clock */
    RCC_ADCCLKConfig(RCC_ADC12PLLCLK_Div1);

    /* Enable ADC4 clock */
    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_ADC12, ENABLE);
       
        ADC_StructInit(&ADC_InitStructure);

        /* Calibration procedure */
        ADC_VoltageRegulatorCmd(ADC1, ENABLE);

        ADC_SelectCalibrationMode(ADC1, ADC_CalibrationMode_Single);
        ADC_StartCalibration(ADC1);
       
        while(ADC_GetCalibrationStatus(ADC1) != RESET );
       
        calibration_value = ADC_GetCalibrationValue(ADC1);

    /* Configure the ADC4 in continuous mode */
    ADC_CommonInitStructure.ADC_Mode = ADC_Mode_Independent;                                                                  
    ADC_CommonInitStructure.ADC_Clock = ADC_Clock_AsynClkMode;                  
    ADC_CommonInitStructure.ADC_DMAAccessMode = ADC_DMAAccessMode_Disabled;            
    ADC_CommonInitStructure.ADC_DMAMode = ADC_DMAMode_OneShot;                  
    ADC_CommonInitStructure.ADC_TwoSamplingDelay = 0;      
    ADC_CommonInit(ADC1, &ADC_CommonInitStructure);

    ADC_InitStructure.ADC_ContinuousConvMode = ADC_ContinuousConvMode_Enable;
    ADC_InitStructure.ADC_Resolution = ADC_Resolution_12b;
    ADC_InitStructure.ADC_ExternalTrigConvEvent = ADC_ExternalTrigConvEvent_0;         
    ADC_InitStructure.ADC_ExternalTrigEventEdge = ADC_ExternalTrigEventEdge_None;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_OverrunMode = ADC_OverrunMode_Disable;
    ADC_InitStructure.ADC_AutoInjMode = ADC_AutoInjec_Disable;
    ADC_InitStructure.ADC_NbrOfRegChannel = 1;
    ADC_Init(ADC1, &ADC_InitStructure);

   /* ADC4 regular channel5 configuration */
    ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 1, ADC_SampleTime_181Cycles5);//2é?ùê±???a21.5us

    /* Enable EOC interrupt */
        ADC_ITConfig(ADC1, ADC_IT_EOC, ENABLE);

    /* Enable ADC4 */
    ADC_Cmd(ADC1, ENABLE);

    /* wait for ADRDY */
    while(ADC_GetFlagStatus(ADC1, ADC_FLAG_RDY) == RESET);
    GPIO_ResetBits(GPIOB,GPIO_Pin_3);
    /* ADC4 start Conversion */
//   ADC_StartConversion(ADC4);   
}
主函数调用ADC1_IN1_Config(),结果程序一直卡在while(ADC_GetCalibrationStatus(ADC1) != RESET );这条AD校准语句上面,为何?
