实在是不想调代码了

关注adc1和adc2

dontium

看看ST的例程，照着人家的做吧。

1、你的那个adc1()和adc2中的功能，应该放到初始化函数中，不要每次都要初始化一次。
2、while(ADC_GetCalibrationStatus(ADC1));
//  ADC_SoftwareStartConvCmd(ADC1, ENABLE);
return(ADC_GetConversionValue(ADC1));
ADC还在校准呢，你就读ADC结果？

关于第一个问题config的问题我不知道是配置成
ADC_RegularChannelConfig(ADC1, ADC_Channel_9, 1, ADC_SampleTime_13Cycles5);
ADC_RegularChannelConfig(ADC1, ADC_Channel_10, 1, ADC_SampleTime_13Cycles5);
还是
ADC_RegularChannelConfig(ADC1, ADC_Channel_9, 1, ADC_SampleTime_13Cycles5);
ADC_RegularChannelConfig(ADC1, ADC_Channel_10, 2, ADC_SampleTime_13Cycles5);
因为涉及到关闭后的再次打开，所以不清楚怎么弄
关于第二个问题，我这两天已经加了while(!ADC_GetFlagStatus(ADC1,ADC_FLAG_EOC)),但是没有效果

这是我发的另外一个帖子，看了你就明白我大概想做的东西了

你不是一分钟搞一次AD转换吗？使用定时器启动单次转换，ADC转换完成后使用中断，在那里读值，这样不影响整个系统的，ADC的开消很小。

亲，这不是关键，关键是通道切换功能没有实现
