STM32F303xC系列ADC校准一直不通过

本来的硬件平台是STM32F303VC,ADC校准能通过。换成STM32F303CC，校准就不行了，程序用的老的固件库。ADC的校准需要什么条件才能成功。初始化代码如下：

        ADC_InitTypeDef      ADC_InitStructure;
ADC_CommonInitTypeDefADC_CommonInitStructure;

/* Configure the ADC clock */
RCC_ADCCLKConfig(RCC_ADC12PLLCLK_Div1);
//RCC_AHBPeriphResetCmd(RCC_AHBPeriph_ADC12,ENABLE);
/* Enable ADC1 clock */
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_ADC12, ENABLE);
/* ADC GPIO configuration */
ADC_GPIO_Configuration();

/* ADC DMA Channel configuration */
ADC_DMA_Configuration();
       
ADC_StructInit(&ADC_InitStructure);
/* ADC Calibration procedure */
        ADC_VoltageRegulatorCmd(ADC1, ENABLE);
ADC_VoltageRegulatorCmd(ADC2, ENABLE);

ADC_SelectCalibrationMode(ADC1, ADC_CalibrationMode_Single);
ADC_StartCalibration(ADC1);
ADC_SelectCalibrationMode(ADC2, ADC_CalibrationMode_Single);
ADC_StartCalibration(ADC2);
        while(ADC_GetCalibrationStatus(ADC1) != RESET )
        {
          calibration_value_1 = ADC_GetCalibrationValue(ADC1);
                debug_log("ADC1 Calibration Value %d",calibration_value_1);
        }
while(ADC_GetCalibrationStatus(ADC2) != RESET )
        {
                calibration_value_2 = ADC_GetCalibrationValue(ADC2);
                debug_log("ADC2 Calibration Value %d",calibration_value_2);            
        }
///* ADC Dual mode configuration */   
ADC_CommonInitStructure.ADC_Mode = ADC_Mode_RegSimul;                                                                  
ADC_CommonInitStructure.ADC_Clock = ADC_Clock_AsynClkMode;                  
ADC_CommonInitStructure.ADC_DMAAccessMode = ADC_DMAAccessMode_1;            
ADC_CommonInitStructure.ADC_DMAMode = ADC_DMAMode_Circular;

ADC_CommonInit(ADC1, &ADC_CommonInitStructure);

ADC_Init(ADC1, &ADC_InitStructure);
ADC_Init(ADC2, &ADC_InitStructure);
       
       
   ADC_TempSensorCmd(ADC1,ENABLE);

   ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 1, ADC_SampleTime_61Cycles5);

官方的例程有校准的，参考一下吧 \en.stm32f30x_dsp_stdperiph_lib\STM32F30x_DSP_StdPeriph_Lib_V1.2.3\Projects\STM32F30x_StdPeriph_Examples\ADC\ADC_BasicExample

求LZ的f303的固件库例程，我只有hal库的，不太会用，我邮箱1483060623@qq.com

用CubeMX下载的芯片包里的例程就是固件库的

之前碰过类似问题，校准时候要确保ADC使能位置0
