stm32f030的AD转换，序列通道单次转换
void adcinit(void){
GPIO_InitTypeDef GPIO_InitStruct;
ADC_InitTypeDef ADC_InitStruct;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1,ENABLE);
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA,ENABLE);
GPIO_InitStruct.GPIO_Pin = GPIO_Pin_1 | GPIO_Pin_4 | GPIO_Pin_5;
GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AN;
GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;
GPIO_Init(GPIOA,&GPIO_InitStruct);
ADC_InitStruct.ADC_Resolution = ADC_Resolution_12b;
ADC_InitStruct.ADC_ContinuousConvMode = DISABLE;
ADC_InitStruct.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_None;
ADC_InitStruct.ADC_DataAlign = ADC_DataAlign_Right;
ADC_InitStruct.ADC_ScanDirection = ADC_ScanDirection_Upward;
ADC_Init(ADC1,&ADC_InitStruct);
ADC_ChannelConfig(ADC1,ADC_Channel_0,ADC_SampleTime_55_5Cycles);
ADC_ChannelConfig(ADC1,ADC_Channel_1,ADC_SampleTime_55_5Cycles);
ADC_ChannelConfig(ADC1,ADC_Channel_2,ADC_SampleTime_55_5Cycles);
ADC_GetCalibrationFactor(ADC1);
ADC_Cmd(ADC1,ENABLE);
}

}
if(ADC_GetFlagStatus(ADC1,ADC_FLAG_EOSEQ) == ENABLE)

ADC_ClearFlag(ADC1,ADC_FLAG_EOSEQ);
}
}
用上面的代码可以实现序列通道单次转换吗？
目的：调用一次getadcvalue()就采集一次数据
求大神指点，while（EOC）不注释掉的话，好像只能调用一次，手册上写，EOC不是读取数据后才会清零吗？
