用stm32f103c8t6标准库配置ADC交叉通道配置代码

以下是基于STM32CubeMX和标准库的ADC交叉通道配置代码示例：

首先，需要在STM32CubeMX中配置ADC，选择所需的通道和采样时间，并启用交叉通道模式。生成代码后，在main.c文件中添加以下代码：

/* ADC initialization function */
static void MX_ADC_Init(void)
{
  ADC_ChannelConfTypeDef sConfig = {0};

  /** Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion) */
  hadc.Instance = ADC1;
  hadc.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4;
  hadc.Init.Resolution = ADC_RESOLUTION_12B;
  hadc.Init.ScanConvMode = ENABLE;
  hadc.Init.ContinuousConvMode = ENABLE;
  hadc.Init.DiscontinuousConvMode = DISABLE;
  hadc.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
  hadc.Init.ExternalTrigConv = ADC_SOFTWARE_START;
  hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT;
  hadc.Init.NbrOfConversion = 2;
  hadc.Init.DMAContinuousRequests = DISABLE;
  hadc.Init.EOCSelection = ADC_EOC_SEQ_CONV;
  if (HAL_ADC_Init(&hadc) != HAL_OK)
  {
    Error_Handler();
  }

  /** Configure for the selected ADC regular channel its corresponding rank in the sequencer and its sample time. */
  sConfig.Channel = ADC_CHANNEL_0;
  sConfig.Rank = 1;
  sConfig.SamplingTime = ADC_SAMPLETIME_28CYCLES_5;
  if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)
  {
    Error_Handler();
  }

  /** Configure for the selected ADC regular channel its corresponding rank in the sequencer and its sample time. */
  sConfig.Channel = ADC_CHANNEL_1;
  sConfig.Rank = 2;
  sConfig.SamplingTime = ADC_SAMPLETIME_28CYCLES_5;
  if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)
  {
    Error_Handler();
  }

  /** Enable ADC1 */
  if (HAL_ADC_Start(&hadc) != HAL_OK)
  {
    Error_Handler();
  }
}

int main(void)
{
  /* MCU Configuration--------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* Configure the system clock */
  SystemClock_Config();

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_ADC_Init();

  /* Infinite loop */
  while (1)
  {
    /* Start ADC conversion */
    if (HAL_ADC_Start(&hadc) != HAL_OK)
    {
      Error_Handler();
    }

    /* Wait for conversion to be completed */
    if (HAL_ADC_PollForConversion(&hadc, 1000) != HAL_OK)
    {
      Error_Handler();
    }

    /* Read the first converted value */
    uint32_t adc_value_1 = HAL_ADC_GetValue(&hadc);

    /* Wait for conversion to be completed */
    if (HAL_ADC_PollForConversion(&hadc, 1000) != HAL_OK)
    {
      Error_Handler();
    }

    /* Read the second converted value */
    uint32_t adc_value_2 = HAL_ADC_GetValue(&hadc);

    /* Print the converted values */
    printf("ADC value 1: %lu\r\n", adc_value_1);
    printf("ADC value 2: %lu\r\n", adc_value_2);

    HAL_Delay(1000);
  }
}

上述代码中，我们初始化了ADC1，并配置了两个采样通道。在无限循环中，我们启动ADC转换，并等待转换完成。然后，我们获取两个转换的值并将其打印出来。在这个例子中，我们使用了printf语句，因此需要确保在工程中启用了半主机模式，并且串口已正确配置。
