一、配置

二、代码

  /* USER CODE BEGIN 2 */
  OLED_Init();
  OLED_Clear();
  OLED_ShowString(0,0,"Hello adc",12,0);
  uint16_t adc_number= 0;
  /* USER CODE END 2 */

  /* USER CODE BEGIN WHILE */
  while (1)
  {
	  HAL_ADC_Start(&hadc1);
	  HAL_ADC_PollForConversion(&hadc1,HAL_MAX_DELAY);
	  adc_number = (uint16_t)HAL_ADC_GetValue(&hadc1);
//	  OLED_Clear();
	  OLED_ShowNum(0,0,adc_number,6,12,0);
	  HAL_Delay(10);
    /* USER CODE END WHILE */
