103的ADC配置，请大家帮我看看问题在哪里

是否解决:

需求是这样的：adc0~3通道由TIM1_TRGO触发注入采样，adc4通道由SWSTART触发规则采样，注入采样4路AD完成后进入ADC中断，规则采样在需要的时候开启并读取。

void adc_init(void)
{
ADC_InitTypeDef ADC_InitStructure;

RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1,ENABLE);
RCC_ADCCLKConfig(RCC_PCLK2_Div6);//60M/6 = 10M
//-------------------------------------
ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
ADC_InitStructure.ADC_ScanConvMode = ENABLE;
ADC_InitStructure.ADC_ContinuousConvMode = DISABLE; //非连续转换
ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;//SWSTART
ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
ADC_InitStructure.ADC_NbrOfChannel = 1;
ADC_Init(ADC1, &ADC_InitStructure);

ADC_RegularChannelConfig(ADC1,ADC_Channel_4,1,ADC_SampleTime_7Cycles5);//通道一转换结果
//-------------------------------------
/* Set injected sequencer length */
ADC_InjectedSequencerLengthConfig(ADC1, 4);

/* ADC1 injected channel Configuration */
ADC_InjectedChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_7Cycles5);
ADC_InjectedChannelConfig(ADC1, ADC_Channel_1, 2, ADC_SampleTime_7Cycles5);
ADC_InjectedChannelConfig(ADC1, ADC_Channel_2, 3, ADC_SampleTime_7Cycles5);
ADC_InjectedChannelConfig(ADC1, ADC_Channel_3, 4, ADC_SampleTime_7Cycles5);

/* ADC1 injected external trigger configuration */
ADC_ExternalTrigInjectedConvConfig(ADC1, ADC_ExternalTrigInjecConv_T1_TRGO);

/* DISable automatic injected conversion start after regular one */
ADC_AutoInjectedConvCmd(ADC1, DISABLE);

/* Enable ADC1 external trigger */
ADC_ExternalTrigConvCmd(ADC1, ENABLE);
ADC_ExternalTrigInjectedConvCmd(ADC1, ENABLE);

ADC1->CR1 |= 0x80; //Interrupt enable for injected channels
//-------------------------------------
ADC_Cmd(ADC1, ENABLE);

ADC_ResetCalibration(ADC1);
while(ADC_GetResetCalibrationStatus(ADC1));
ADC_StartCalibration(ADC1);
while(ADC_GetCalibrationStatus(ADC1));
}
