需要用到STM32F373中的SDADC1和SDADC2，而且需要把SDADC1的增益设置为32，而SDADC2设置增益为1；程序如下，发现SDADC1的增益设置不成功，不知哪里出错了？求教！


  /*Analog Input configuration conf0: use single ended zero reference */
        SDADC_AINStructTypeDef  SDADC1_AINStructure;
        SDADC_AINStructTypeDef  SDADC2_AINStructure;
        
  SDADC2_AINStructure.SDADC_InputMode = SDADC_InputMode_SEZeroReference;
        SDADC2_AINStructure.SDADC_Gain = SDADC_Gain_1;
  SDADC2_AINStructure.SDADC_CommonMode = SDADC_CommonMode_VSSA;
  SDADC2_AINStructure.SDADC_Offset = 0;
  SDADC_AINInit(POT_SDADC2, SDADC_Conf_0, &SDADC2_AINStructure);  
        
        SDADC1_AINStructure.SDADC_InputMode = SDADC_InputMode_SEZeroReference;
        SDADC1_AINStructure.SDADC_Gain = SDADC_Gain_32;
  SDADC1_AINStructure.SDADC_CommonMode = SDADC_CommonMode_VSSA;
  SDADC1_AINStructure.SDADC_Offset = 0;
        SDADC_AINInit(POT_SDADC1, SDADC_Conf_0, &SDADC1_AINStructure);

按照STM32一贯德性，要操作个什么外设前，必须先开相应的外设时钟，否则设置无效。
