1：首先使用stm32cube 配置ADC的硬件配置

uint8_t     tx_Value[2000];
struct ADC_Sample
{
	 int  ADC_count;
    uint32_t	ADC1_Sample_data;
	uint32_t  SDADC_Sample_data[];
	
} ADC;

MX_ADC1_Init();

  while (1)
  {
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
	  //  CDC_Transmit_FS((uint8_t *)"Hello world !\r\n", sizeof("Hello world !\r\n"));
		HAL_ADC_Start(&hadc1);
		  HAL_ADC_PollForConversion(&hadc1, 50);
		if(HAL_IS_BIT_SET(HAL_ADC_GetState(&hadc1), HAL_ADC_STATE_REG_EOC))
		{  
			
			ADC.ADC1_Sample_data = HAL_ADC_GetValue(&hadc1);
			tx_Value[3]= ADC.ADC1_Sample_data & 0x00FF;
		  tx_Value[2]= (ADC.ADC1_Sample_data & 0xFF00)>>8 ;
		}  
		tx_Value[0]=0X01;
		tx_Value[1]=0XEF;
		CDC_Transmit_FS(tx_Value,4);
		 HAL_Delay(500);
		 }
