stm8s003F3的ADC采集影响到有adc功能管脚的正常输出

这是初始化代码

static void AD_Configuration(void)

{

  GPIO_Init(GPIOD,GPIO_PIN_3, GPIO_MODE_IN_FL_NO_IT);           

  GPIO_Init(GPIOD,GPIO_PIN_5, GPIO_MODE_IN_FL_NO_IT);          

  GPIO_Init(GPIOD,GPIO_PIN_6, GPIO_MODE_IN_FL_NO_IT); 

  CLK_PeripheralClockConfig(CLK_PERIPHERAL_ADC, ENABLE);



  /* De-Init ADC peripheral*/

  ADC1_DeInit();

  /* Init ADC1 peripheral */

                 ADC1_Init(ADC1_CONVERSIONMODE_SINGLE, (ADC1_CHANNEL_4|ADC1_CHANNEL_5|ADC1_CHANNEL_6), ADC1_PRESSEL_FCPU_D2,\

            ADC1_EXTTRIG_TIM, DISABLE, ADC1_ALIGN_RIGHT,  ADC1_SCHMITTTRIG_CHANNEL4,DISABLE);

  

        ADC1_SchmittTriggerConfig(ADC1_SCHMITTTRIG_CHANNEL5,DISABLE);           //ad功能 关闭施密特触发器 减少对ad影响

        ADC1_SchmittTriggerConfig(ADC1_SCHMITTTRIG_CHANNEL6,DISABLE);

        ADC1_ScanModeCmd(ENABLE);

  ADC1_DataBufferCmd(ENABLE);

  ADC1_ITConfig(ADC1_IT_EOCIE,DISABLE);

}

[code]这是读数据的代码，在timer4中断中调用，4ms一次，ad读取正常，只是会影响AIN2,3的输出



void ReadAdResult(void)

{

        DS_INT16U  i,ADResult[3];

  SYSGLDATA *pSysData=NULL;

  DS_INT16U  *pDataPtr=NULL;



  pSysData=&g_pSysGloble->SysData;

  pSysData->AD1[pSysData->Ptr]=ADC1_GetBufferValue(4);

  pSysData->AD2[pSysData->Ptr]=ADC1_GetBufferValue(5);

        pSysData->AD3[pSysData->Ptr]=ADC1_GetBufferValue(6);



  pSysData->Ptr++;

  if(pSysData->Ptr>=10) pSysData->Ptr=0;

  pDataPtr=pSysData->AD1;

  for(i=0;i<3;i++)  ADResult[i]=0;

  for(i=0;i<10;i++)

  {

    ADResult[0]+=*(pDataPtr+i);

    ADResult[1]+=*(pDataPtr+i+10);

                ADResult[2]+=*(pDataPtr+i+20);

  }

  pSysData->ADdata1=ADResult[0]/10;

  pSysData->ADdata2=ADResult[1]/10;

        pSysData->ADdata3=ADResult[2]/10;//1.8

        

  g_pSysGloble->SysData.ADVoltage1=(g_pSysGloble->SysData.ADdata1*1.82)/g_pSysGloble->SysData.ADdata3;    //vo报警点

  g_pSysGloble->SysData.ADVoltage2=(g_pSysGloble->SysData.ADdata2*1.82)/g_pSysGloble->SysData.ADdata3;    // TEST  自检点

  //g_pSysGloble->SysData.ADVoltage3=(g_pSysGloble->SysData.ADdata3*4.95)/1023;    //1.8V   

        g_pSysGloble->SysData.ADVoltage3=(g_pSysGloble->SysData.ADdata3*5)/1023;    //1.8V   





        /* De-Init ADC peripheral*/

   ADC1_DeInit();

  /* Init ADC1 peripheral */

  ADC1_Init(ADC1_CONVERSIONMODE_SINGLE, (ADC1_CHANNEL_4|ADC1_CHANNEL_5|ADC1_CHANNEL_6), ADC1_PRESSEL_FCPU_D2,\

    ADC1_EXTTRIG_TIM, DISABLE, ADC1_ALIGN_RIGHT,  ADC1_SCHMITTTRIG_CHANNEL4,DISABLE);

                

        ADC1_SchmittTriggerConfig(ADC1_SCHMITTTRIG_CHANNEL5,DISABLE);           //ad功能 关闭施密特触发器 减少对ad影响

        ADC1_SchmittTriggerConfig(ADC1_SCHMITTTRIG_CHANNEL6,DISABLE);

  ADC1_ScanModeCmd(ENABLE);

  ADC1_DataBufferCmd(ENABLE);

  ADC1_ITConfig(ADC1_IT_EOCIE,DISABLE);

  /*Start Conversion */

  ADC1_Cmd(ENABLE);//启用ADC1

  ADC1_StartConversion();
