ADC匹配配置问题

__IO uint16_t ADCConvertedValue[4];//转换的4通道AD值

DMA_InitStructure.DMA_BufferSize = 4;//数据长度为4


ADC_InitStructure.ADC_NbrOfChannel = 4;//转换的ADC通道的数目为

ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_7Cycles5); //ADC1通道2转换顺序为1，采样时间为7.5个周期 
  ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 2, ADC_SampleTime_55Cycles5);//ADC1通道3转换顺序为2，采样时间为55.5个周期 
  ADC_RegularChannelConfig(ADC1, ADC_Channel_8, 3, ADC_SampleTime_55Cycles5);//ADC1通道8  
  ADC_RegularChannelConfig(ADC1, ADC_Channel_9, 4, ADC_SampleTime_55Cycles5);//ADC1通道9 

ADC配置时，这几个参数必须匹配！否则ADCConvertedValue数组中的值会跳动！
