STM32 ADC通道9 HAL库初始化

以下是使用HAL库初始化STM32 ADC通道9的示例代码：

ADC_HandleTypeDef hadc;

void ADC_Init(void)
{
  ADC_ChannelConfTypeDef sConfig;

  // 初始化ADC外设
  hadc.Instance = ADC1;
  hadc.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4;
  hadc.Init.Resolution = ADC_RESOLUTION_12B;
  hadc.Init.ScanConvMode = DISABLE;
  hadc.Init.ContinuousConvMode = DISABLE;
  hadc.Init.DiscontinuousConvMode = DISABLE;
  hadc.Init.NbrOfDiscConversion = 0;
  hadc.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
  hadc.Init.ExternalTrigConv = ADC_SOFTWARE_START;
  hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT;
  hadc.Init.NbrOfConversion = 1;
  hadc.Init.DMAContinuousRequests = DISABLE;
  hadc.Init.EOCSelection = ADC_EOC_SINGLE_CONV;
  HAL_ADC_Init(&hadc);

  // 配置ADC通道9
  sConfig.Channel = ADC_CHANNEL_9;
  sConfig.Rank = 1;
  sConfig.SamplingTime = ADC_SAMPLETIME_480CYCLES;
  sConfig.SingleDiff = ADC_SINGLE_ENDED;
  sConfig.OffsetNumber = ADC_OFFSET_NONE;
  sConfig.Offset = 0;
  HAL_ADC_ConfigChannel(&hadc, &sConfig);
}

在此示例中，我们首先初始化了ADC外设，然后配置了ADC通道9。请根据您的具体需求进行修改。
