融合已经完成，目前只做出一个通道的ADC，用的是有DMA的，ADC2，通道2，转换结果AD_value=ADC_GetConversionValue(ADC2);然后无限发射给另一个NRF，NRF通过转USB虚拟串口发给上位机，上位机也能正常接收到转换结果，但是不知双通道的ADC怎么做，想加个通道1，需要怎么改…… GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;

GPIO_Init(GPIOA, &GPIO_InitStructure);

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;

 GPIO_Init(GPIOA, &GPIO_InitStructure);

……………………

ADC_InitStructure.ADC_NbrOfChannel = 2;

……………………

ADC_RegularChannelConfig(ADC2, ADC_Channel_1, 1, ADC_SampleTime_55Cycles5);

ADC_RegularChannelConfig(ADC2, ADC_Channel_2, 2, ADC_SampleTime_55Cycles5);

……………………

AD_value=ADC_GetConversionValue(ADC2) 是这样么？

 

可是这样接收到的数据是这样的

The current AD value = 0x0FFF
The current AD value = 0x0000
The current AD value = 0x0000
The current AD value = 0x0000
The current AD value = 0x0000
The current AD value = 0x0FFF
The current AD value = 0x0000
The current AD value = 0x0000
The current AD value = 0x0000
The current AD value = 0x0000
The current AD value = 0x0000
The current AD value = 0x0FFF

(我一个脚测5V一个脚测0v)
