STM32F373的SDADC增益设置问题

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

  /*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);
